The aim of this study was to evaluate the nutritional potential of the Saba pulp for better valorisation. The study was carried out on the fruit of Saba Senegalensis collected in the north area of Côte d'Ivoire. After the pulp extraction, the biochemical analyses were determined. Macronutrients (total carbohydrate, proteins and fat content), micronutrients (mineral and vitamin) and nutritional profile of the pulp were determined. The results showed that proteins and fat content (2.91 ± 0.51%) and (1.48 ± 0.21 %) respectively were lower in the Saba pulp. On the other hand, total carbohydrate (8.42 ± 0.74 %) and total sugar (6.13 ± 0.12 %) were higher in this pulp. The results showed that Saba pulp was rich in potassium (116.6 ± 2.06 mg/100g), vitamin C (36.67 ± 2.22 mg/100g) and β-carotene (189.62 ± 1.33µg/100g). It contains also phytonutrients such as total phenols (264.76 ± 4.54 mg/100g) and the antinutritionals factors such as phytates (31.18 ± 0.13 mg/100g). The nutrient profile by the determination of scores SAIN > 5 and LIM <7.5 classified the Saba senegalensis pulp in food of group 1, recommended foods for health. Due to the high energy value, Saba fruit could be recommended as a local juice to prevent certain pathology of the malnutrition.
In the tropical countries, many wild fruits are consumed by the rural populations. These fruits contribute to improve quality of feed rations through the supply in micronutrients, but very few information are available on these local fruits concerning their annual productions, their vegetative cycles 1. According to 2, some of these fruits, although known by the people, were less passion due to their organoleptic quality, the eating habits and especially of the ignorance of their nutritional values and therapeutic. Among these fruits species, appears Saba senegalensis which is a species of plants of the family of Apocynaceae.
Saba senegalensis is a wild liana which pushes in African savannahs. As an indigenous fruits tree, Saba senegalensis fruit is called by different language dialects. This fruit is called Saba in French, zaban in Malinké language, amani in Baoulé, wèda in Mooré, Madd in Wolof and côcôta in the urban language of Côte d'Ivoire. Saba Senegalensis is a globulous envelope which contains seeds coated with yellow pulps and juicy 3. Data from 4 demonstrated that these orange-yellow fruit pulps and juicy are acid and sweet but are not appreciated by everyone because the acid taste similar to that of tamarind can disturb sometimes. Nutritionally, the studies carried of by 4 in Burkina Faso, reported that the fruits of Saba senegalensis are a true source of provitamin A (β-carotene = 1559 µg/g) which would play a significant role in the prevention of cancer. Moreover, 5 in Burkina Faso and 6 in Senegal revealed that Saba senegalensis are high content of antioxidants activities (17.57 mmol AEAC/100 g for pulp and 18.4 μg/mL for leaves). Previous studies stablished by 7 showed that Saba comorensis pulp was acidic (pH =3.10 ± 0.04) and rich in crude protein (4.83 ± 0.01 g/100 g), dietary fibre (7.97 ± 0.85 g/100 g), and minerals like magnesium (894.9 ± 0.32 mg/100 g) and calcium (209.0 ± 0.51 mg/100 g) According to 8 and 9, the indigenous fruits have great opportunities to be developed into products like juice, jam and wine that can improve not only the nutrition and health of people, but also livelihoods.
In Côte d'Ivoire, the previous studies carried out by 10, 1 and 11 in the ethnobotanic field showed the use of leaves, roots and fruit of Saba senegalensis in human health for the treatment of certain diseases such as the dysentery, the diarrhoea and the cough. The nutritional value of Saba senegalensis pulp has not been investigated. Yet a better knowledge of the nutritional composition followed by an extension of the research results will make it possible to remedy the problems of malnutrition considerably in Côte d’Ivoire. In this study, the aim was to determine the nutritional potential of the pulp of Saba senegalensis for a better valorisation in Côte d'Ivoire.
The plant material was collected from Waraniéné, area located at approximately 5 km of Korhogo (northern of Côte d’Ivoire) (Figure 1).
The Saba Senegalensis fruits (10 kg) were cutted into half with stainless steel knife. The combination of the pulp with seeds was removed with stainless spoon. The pulp together with the seeds were put into the mixer of mark ilux (NO: LX-176P/AC: 220-240V 50Hz 350W) for mixing. The pulp together with the seeds were put into the stainless-steel sieve and blended manually to separate the seeds from the pulp. The pulps obtained was stored at -20°C for the various analysis
The pH is determined according to the method of 12 using a pH-meter (Consort pH-meter P 107).
Titratable acidity
Titratable acidity was determined according to AOAC standard method by titrating 10 ml of the pulps and juices against 0.1 M NaOH standard solution using phenolphthalein indicator 13.
Dry matter content
Moisture was determined by drying the sample at 105°C for 24 h according to 13. Samples were then cooled in desiccators and weighed. The loss of weight was expressed as a percentage of the initial weights of the samples give their moisture content.
Protein content
Protein was determined by determination of total nitrogen according to the Kjeldahl method 14. The principle: under the action of NAOH and after sulphuric mineralization in the presence of catalyst (CuSO4), ammoniac formed was neutralized. The ammonia in the sample solution was then distilled into the boric acid until it changed completely to bluish green. The distillate was then titrated with 0.1 N HCl solutions until it became colourless. The percent total nitrogen and crude protein were calculated using a conversion factor of 6.25.
Fat content
Fat was determined based on the Sohxlet extraction method of 15. Five gram (5.0 g) of the sample was introduced into a cartridge of Whatman. An empty flask reweighed and containing 60 ml of hexane was placed on the heating block of the Soxhlet apparatus and heated at 110°C. After 6 hours of extraction, the flask was removed from apparatus and then the solvent was evaporated on a Rotary Evaporator. The flask containing the fat and residual solvent was placed on a water bath to evaporate the solvent followed by a further drying in an oven at 60°C for 30 min to completely evaporate the solvent. It was then cooled in desiccators and weighed. The fat obtained was expressed as a percentage of the initial weight of the sample.
Total carbohydrate content
Total carbohydrate content is determined by difference method [100% - (% moisture + % ash + % fat + protein %)].
Ash content
Ash was obtained according to 13. A 5 g sample was weighed into a previously dried and weighed porcelain crucible. The crucible with its content was placed in a furnace at 550°C for 6 h. After cooling in desiccators, the crucible with its content was weighed. The weight of the ash was expressed as a percentage of the initial weight of the sample.
Mineral content
Mineral content are determined by atomic absorption spectrophotometry. Ash (0.1g) is weighed in platinum crucibles to which was added 1 ml of distilled water. In each crucible, 5 ml of hydrofluoric acid 50% and 2 drops of sulfuric acid (v / v) were added. Whole, well homogenized and heated at 100°C until fully evaporated. Residue obtained was dissolved in 10 ml of 50% hydrochloric acid. Solution was left to stand for 10 minutes on the bench and the final volume was brought to 100 ml.
Vitamin C content
The method used for the dosage is that described by 16. Ten (10) grams of pulp are watered in 40 mL of acetic metaphosphoric-acid acid (2%; p/v). The mixture obtained is centrifuged with 3000 trs/min during 20 min. The supernatant is adjusted to 50 ml with water distilled boiled and cooled to be kept dry. A test specimen of 10 mL introduced into an Erlenmeyer is titrated with the 2.6 DCPIP with 0.5 g/L until the turn with the pink persisting during 30s.
Fibbers Content
Crude fibers were proportioned according to the method described by 13. Two (2) gram of the sample are weighed in a balloon. 50 mL of sulphuric acid 0.25 N was added to the contents was homogenized and the whole carried with boiling during 30 min under cooling agent with backward flow. Then, 50 mL of sodium 0.31N are added to the contents and the whole carried to boiling during 30 min under cooling agent to backward flow. The extract obtained is filtered on filter paper Whatman and the residue is washed several times at hot water until complete elimination of alkalis. After elimination, the residue is dried with the drying oven with 105°C during 8 H, cooled with the weighed desiccator then. The residue obtained is incinerated with the furnace with 550°C during 3 h. Finally, it is cooled with the desiccator then weighed ashes.
Phenolic content
The total phenolics were estimated by the method of Folin-Ciocalteu 17. 800 µl of reagent of Folin-Ciocalteu are added to 200 µl of pulp extract, then the mixture is left at ambient temperature during 2 min. 1 ml of sodium carbonate (75g.l-1) was added. The reactional mixtures are agitated and incubated 15 min with 50°C. The reading of the absorptance with 760 nm is done with help to a spectrophotometer UV 1205. The content of the phenolic compounds is calculated starting from a calibration curve.
Flavonoids content
The dosage of the flavonoïdes was carried out according to the method described by 18. A volume of 0.5 ml of pulp extract is introduced into a tube. At this volume, is successively added 0.5 ml of distilled water, 0.5 ml of aluminium chloride with 10%, 0.5 ml of acetate of potassium 1N and 2ml of distilled water. The tube is left at rest during 20 min with the darkness and the optical density is read to 415 nm against a white.
The quantification of the phytates is based on the method of 19. The optical density was read to 470 nm against a white.
The oxalic acid content was proportioned according to the method described by 14.
The dosage of the tannins was carried out according to the method described by 20. One (1) ml of pulp extract is introduced into a test tube. To the contents of the tube 5 ml of reagent are added to vanillin. The tube is left at rest during 20 min with the darkness and the optical density is read to 500 nm against a white.
The nutritional profile used was the SAIN and LIM system described by 21. The SAIN refers to the favourable aspects of the food (qualifying nutrients) and the LIM refers to the unfavourable aspects (disqualifying nutrients). A food has a good profile when its SAIN is high and its LIM is low.
SAIN calculation formula is as follows:
RNI (Recommended nutritional intake)
The LIM calculation formula is as follows:
SFA= Saturated fatty acid
These two values plotted on a graph used to classify foods into four groups. It considers two acceptability thresholds (SAIN> 5 and LIM <7.5):
1. Foods recommended for health (SAIN> 5 and LIM <7.5)
2. Neutral foods (SAIN <5 and LIM <7.5)
3. Foods recommended in small quantities or occasionally (SAIN> 5 and LIM> 7.5)
4. Foods to limit (SAIN <5 and LIM> 7.5).
Results made in triplicate measurements were expressed as means with standard deviation with statistica 7.1. Graphical representations were made with Microsoft Word and Microsoft Excel.
The pH and titratable acidity value, ash (%) and the dry matters (%) contents of the Saba pulp are represented in Figure 2. Results showed that Saba senegalensis pulp has a low value of pH (3.03 ± 0.01) and titratable acidity (0.28 ± 0.01 %). It also contains 0.46 ± 0.01 % of ash and 13.26 ± 0.81 % of dry matter.
The composition in macronutrients of the Saba pulp is presented in Figure 3. Results showed the low content of protein, lipid and reducer sugar respectively (2.91 ± 0.51 %), (1.48 ± 0.21 %) and (2.03 ± 0.08 %). On the other hand, total carbohydrates and total sugars content were higher with respective values of 8.42 ± 0.74 % and 6.13 ± 0.12 %.
The minerals, vitamin C, β-carotene and fibbers contents of the Saba pulp are represented in Table 1. The results showed that Saba pulp is rich in minerals content. This pulp has a high percentage of potassium (116.96 ± 2.06 mg/100g), a considerable quantity in calcium (36.61 ± 2.79 mg/100g). Nevertheless, it is weak in zinc (0.38 ± 0.11 mg/100g) and in iron (1.04 ± 0.65 mg/100g). The results showed that Saba pulp is rich in vitamin C and β-carotene with respective contents of 36.67 ± 2.22 mg/100g and 189.62 ± 1.33 µg/100g. Concerning the fibbers, Saba pulp contains a low fibbers content of 0.20 ± 0.02 %.
The phytonutrients content and antinutritionals factors content are showed in Table 2. The results showed the high content of oxalic acid, total phenols and tannins with respective values of 381.33 ± 12.67 mg/100g, 264.76 ± 4.54 mg/100g and 198.94 ± 1.19 mg/100g. As for as the contents of flavonoids and phytates, results showed the low values respectively of 53.44 ± 1.16 mg/100g and 31.18 ± 0.13 mg/100g.
Figure 4 shows the SAIN and LIM score of the Saba pulp. The SAIN score of the pulp was 18.85 and LIM score was 2.29. Results showed that Saba senegalensis pulp have a good nutritional profile because their SAIN were higher than 5 and LIM were lower than 7.5. The different SAIN and LIM scores obtained show that Saba senegalensis pulp studied belongs to Group 1 foods. This group contains foods recommended for health.
The objective of this study was to evaluate the nutritional potential of Saba senegalensis pulp for better valorization. The pH value helps to determine the state of deterioration of the fruit and is therefore associated with its quality and safety. In this result, the low pH value obtained (3.03) showed that the S.senegalensis pulp is acid and it will be able to resist of microbial activities, especially the pathogenic germs and could be conserved for long time. These results were accordance with those obtained by 22 in similar fruits such as passion (2.77) and the mango (3.90). The previous studies carried out by 23 reported that pH between 2.5 and 5.5 prevents the multiplication of micro-organisms and involves a long conservation of the fresh fruit. Like pH, titratable acidity is also very important for the determination of the pulp fruit quality. Titratable acidity is related to the sour taste of food and expresses the quantity of organic acids. The low titratable acidity value obtained in these results could be explained by the organic acids content in Saba pulp. According to 24, the organic acids contents have the capacity to reduce the pH and the growth of certain bacteria pathogenic. Due to the low pH and low acid titratable values obtained in this result, S. senegalensis pulp could be used as food preservative.
The moisture content in S.senegalensis pulp was relatively high (86.73 ± 0.46 %). This value vas higher than those obtained by 7 in Saba comorensis pulp (74.08 ± 0.15%), mango (83.11 ± 0.85 %), and passion juice (82.1 ± 0.85 %), but lower than those obtained in orange juice (87.1 ± 0.15 %). Moisture determination is one of the most important and the most measurements used in processing and testing of food. Moisture content is importance to both the stability and quality of foods. According to 25, the moisture of the pulpy fruits is about 80 to 90 %.
Concerning the composition of macronutrients of Saba senegalensis (S.senegalensis) pulp, the results showed the low content of crude proteins (2.91 ± 0.51 %). Most fruit pulps often contain less protein. This low protein content was comparable with those obtained by 26 in the juice of baobab leaves (Adansonia digitata L.) which varies between 1.80 % and 2.60 %, but higher than that obtained by 27 in pineapple juice (Ananas comosus L.) (0.54 %). Due to the low protein content, S.senegalensis like the other fruit could not be excellent source of protein.
Fat content is known to provide high energy content and can be reservoir of fat-soluble vitamins.
According to 28, food with low fat content is good for obese patients as they don’t require high levels of carbohydrates. In this study, the lipid content obtained (1.48%) is lower than those obtained by 29, 30 in the pulp of Saba (8.92%), but higher than that of the table of composition of food in West Africa (0.2 ± 0.1%). The difference of fat content obtained in this result and those of the literature could be explained either by the different varieties studied, or by the nature of solvent and the extraction method used. The pulp of S.senegalensis has a low content of energy ≈ 58.64 kcal. This low content of energy can be explained by the low contents of macronutrients in S. senegalensis pulp. Considering its low energy value, Saba senegalensis fruit could be recommended to the obese and diabetic patients or in overweight.
The carbohydrates content obtained in this result (8.42 ± 0.74 %) was lower than those of by 28 in the Saba pulp (14.23%). In addition, the carbohydrates content obtained was lower than those available in the composition table of food of West Africa which is 17.1%. The difference of these results could be explained either by the various varieties used, or by the various extraction and dosage methods. The studies carried out by 31 have showed that sugar contents vary according to the climate, the stage of maturation, the exposure to the sun, the availability of water and the content of minerals of the soils. The total sugar contents of S.senegalensis pulp (6.13 %) were in agreement with those of wild fruits such as Ziziphus mauritiana Lamk. varying from 5.4 to 10.5% 32. In this study, the low reducer sugar content of S. senegalensis is comparable to those of oranges and tangerines which varies between 2 and 4% 33. These values were lower than those obtained by 34 on cashews (7.8%). Taking into the contents obtained in this study, S.senegalensis would constitute a considerable source of sugars which provide calories, and confer on the fruits their sweet savors.
The ash content represents the total quantity of minerals present in food. The ash content in S.senegalensis was 0.46 ± 0.01%. This value was in agreement with that reported in the table of composition of food in West Africa which is 0.40% 35. Studies carried out by 36 showed that the micronutrients do not provide calories but they play a significant role in the metabolic processes of the organism. The results showed that the pulp of Saba senegalensis is an excellent source of minerals compared to other consumed fruits. Among these minerals, potassium is present in high quantity (116.96 ± 2.06 mg/100g). This result is comparable with that of 37 which showed that potassium is the most abundant mineral in the pulp of baobab. In this result, the K/Na ratio was 26.40. This ratio is higher than that recommended by 38 which is 5.0. The K/Na ratio is a significant parameter in the nutritional evaluation of food especially for the persons suffering from hypertension. Due to the high content of potassium and its availability in Saba senegalensis pulp, the consumption of this fruit could help to fill the daily nutritional requirement in potassium and to avoid disfonctionnements of the human organism. Saba senegalensis is a significant source of calcium (36.61 ± 2.79 mg/100g). This result is higher than that reported by 39 on the orange fruits (25.50 ± 1.90). Saba senegalensis fruit contained a low amount of crude fibber (1.52 ± 0.06%) as compared to that of the table of composition of food in West Africa which is 1.30. This result is lower than that reported by 28 on Saba fruit which is 13.52%. This difference could be explained by various conditions: geographical localization, the genetic constitution, the state of the ground, climatic conditions and the methods of culture and analysis. The pulp of S. senegalensis is also rich in vitamin A (β-carotene ≈ 189.62 ± 1.33 μg / 100g) and vitamin C. The β- carotene reported in this study is much lower than that of Saba senegalensis juice (1559 μg / 100g) as has been reported by 4, but higher than that reported in the West African food composition table (traces). Β-carotene is converted into retinol (vitamin A) in the human organism with a better yield estimated at 1/6 40. Vitamin A intervenes in growth, vision, and resistance to infection. Its deficiency is a major contributor to infant-juvenile mortality 41. Due to the high vitamin content, Saba pulp could be a promising choice to increase dietary intake of carotenoids. Moreover, the consumption of this pulp could be beneficial for health considering the protective role and the antioxidant capacity of the vitamin C that it contains.
Like the composition in macro and micronutrients, Saba senegalensis pulp contains also phytonutrients which play the role of antioxidants. Saba pulp has a total phenol content of 264.76 ± 4.54 mg / 100g. This content is higher than that of Safou (100 mg / 100g) obtained by 42. The flavonoids content in this result (53.44 ± 1.16 mg / 100g), is higher than that of the apple (37.27 mg / 100g) obtained by 43. The high levels of total phenols of Saba pulp could explain its astringency which would limit its consumption. This result also showed the high content of tannin (198.94 ± 1.19 mg/100g). Antioxidant compounds in food play an important role as health protecting factor. Scientific evidence suggests that antioxidants reduce the risk of chronic diseases including cancer and heart disease. The fact that S.senegalensis pulp contains the high content of antioxidants such as tannins and flavonoids, the consumption of this fruit in sufficient amount could provide nutrients and adequate protection against diseases.
The results showed that Saba pulp contains antinutritional factors such as phytates (31.18 ± 0.01 mg / 100 g) and oxalic acids (381.33 ± 12.67). The phytate content obtained in this result was lower than that of baobab pulp (200 mg / 100 g) reported by 44. Phytates have the characteristic to chelate the minerals by generating insoluble molecular complexes with divalent cations such as Ca2+, Fe2+, Zn2+or Mg2+, which can modify their bioavailability and decrease their absorption. The high content of oxalate (381.33 ± 12.67 mg / 100g) in this result could be cause the irritation in the mouth and interferes with the absorption of minerals especially bivalent calcium.
As far as the nutritional profile, results showed that Saba senegalensis pulps have a good nutritional profile because their score SAIN is higher than 5 and their score LIM is lower than 7.5. These score SAIN and LIM have classified S. senegalensis in the group 1 food. This group contains foods recommended for health. The use of the SAIN and LIM system help to choose the best food for children and also help to reduce malnutrition. These results were in accordance with those obtained by 45. These authors demonstrated that beans and peas have LIM scores below 7.5 and SAIN scores above 5. Beans and peas belong to the group of foods recommended for health. Results obtained in S.senegalensis pulp were in accordance with those obtained by 46, 47, 48. These authors in previous studies are demonstrated that the group 1 foods are characterized by the low-calorie, but rich in mineral, and vitamin.
This study determined the biochemical composition and nutritional potential of Saba senegalensis fruit. The results were showed that the pulp has a low content of proteins, but high content of vitamin C, β-carotene and minerals. The nutritional profile of Saba senegalensis pulp has shown that this fruit is healthy food for consumption. So it can be recommended for the health and growth of children. The results suggested that the consumption of the fruit in sufficient amount could provide nutrients and adequate protection against diseases. In the same way, the implementation techniques for valorization of the pulp and juice will make it possible to reach a wider public and will make this resource available out of season.
