“…The time of each phase, therefore, sometimes varied between the studied trees and between years in the same tree, suggesting that there was high variability between D. edulis fruits, including those from the same AEZ. These findings were in accordance with those of previous studies showing that apparently homogeneous groups may exhibit considerable variations [2].…”

Dacryodes edulis (G. Don) H.J. Lam is an underexploited oil-bearing fruit tree highly appreciated in the Central Africa rainforest. To improve horticultural management and provide relevant data to scientists for physiological studies, the reproductive phenology of D. edulis as well as their fruit (safou) development and ripening indexes has been defined and correlated to climatic conditions. Changes in safou were assessed in four production localities in Cameroon. Fruit-setto-ripening time was evaluated over 2 consecutive production years. Four fruits developmental and ripening stages and their durations were determined as follows: The putative cell division (1-2 weeks); putative elongation (10-14 weeks); pre-ripening (2-7 weeks); and ripening phases (3-5 weeks). Rainfall, average, and cumulative temperatures were found to be correlated with the chronology of reproductive phenophases. The average temperature during the period ranging from the floral bud emergence to the fruit set can be used to predict the thermal time. Similarly, the average ambient temperature during the period from floral bud emergence to anthesis can help to determine the temperature to be cumulated during the ripening phase. These findings are considerable contributions that could help producers to enhance the industrial management of safou sector, reduce fruit perishability, and better control their harvesting time.

“…Overall, safou has a high nutritional value. Its mesocarp or pulp can be eaten dry, raw, roasted, or boiled in hot water [2]. Safou contains 40-70% of lipids (on dry matter) [3] and its oil is widely used in pharmaceutical, cosmetics, and food industries [4].…”

“…Decoctions from different parts of the plant are used to relieve certain digestive disorders caused by microbial infection ( Ebana et al, 2016 ). The D. edulis fruit has traditionally been consumed (boiled or roasted) due to its nutritional and medicinal properties ( Kadji et al, 2016 ), while the seeds, which are usually discarded, are known to contain high amounts of soluble carbohydrates and lipids ( Bratte, 2010 ). The documented antimicrobial benefits to human health and nutrition informed the choice of the D. edulis plant for evaluation for its suitability in use as feed supplement and growth promoter in indigenous chicken in this study.…”

This study aimed at testing the efficacy and safety of Dacryodes edulis plant parts in diets fed to chicken. The plant has potential for use as a natural prebiotic to substitute the conventionally used antibiotic growth promoters in poultry production. Phytochemical analyses of the plant leaves, stem, and bark combination (stembark) and seed powders from the D. edulis were carried out. The powder from the three D. edulis plant parts were used as supplement in formulating six experimental diets tested in this study. The diets were TL0Ed (0.5% leaves powder), TL1Ed (1.0% leaves powder), TB0Ed (0.5% stembark powder), TB1Ed (1.0% stembark powder), TS0Ed (0.5% seeds powder), and TS1Ed (1.0% seeds powder). Besides, a positive (T+ positive control; 0.5-g oxytetracycline as recommended by the manufacturer) and a negative (T- negative control; having no commercial antibiotic and no plant supplement) diets were prepared for comparison purposes. The diets were fed to a total of 288 dual-purpose chicken for a period of 14 weeks. The chicken growth and body composition characteristics, blood chemistry, and microbiota count were collected and used as indicators of the plant parts efficacy and safety. The analysis of the D. edulis plant parts significantly differed (P ≤ 0.05) in their phytochemical contents. The initial body weight and feed conversion efficiency ratios were not significantly different (P ≥ 0.05) between and among treatment groups. However, significant differences (P ≤ 0.05) were detected in the feed intake and body weight gain at eighth week. Live weight at eighth week was significantly different (P ≤ 0.05) with its values ranging between 503.32 and 614.93 g for treatments TL1Ed and TNeg-, respectively. The dietary treatment of D. edulis leaves, stembark, and seed powder at the two inclusion levels significantly (P ≤ 0.05) decreased the colonies forming unit of Escherichia coli and Salmonella sp. as compared with negative control treatment in the eighth week phase. The level of glucose, total cholesterol, triglycerides, aspartate aminotransferase, alanine amino transferase, alkaline phosphatase, and the packed cell volume did not differ significantly (P ≥ 0.05) between and among dietary D. edulis treatments. The findings from this research provide crucial information on the efficacy and safety of D. edulis plant parts. This is an important step in testing the potential of the plant in use as a prebiotic in chicken feeds production.

“…In recent years, attention has focused on unconventional crops that may be of interest for local or industrial development (Ricinodendron heudoletii, Irvingia gabonensis, Dacryodes edulis) of populations in Africa [1,2,3]. The safoutier (Dacryodes edulis), produced in many countries of Central Africa and the Gulf of Guinea [4] has a strong economic potential which can contribute to the reduction of poverty of the rural population [5].…”

The objective of this study was to assess the impact of post-harvest softening on parameters (nutritional and antinutritional) of saffron pulp (Dacryodes edulis). Thus, the safou fruits were picked at physiological maturity and stored at room temperature (27±1.2 °C) for 12 days during which five stages of softening (S0, S1, S2, S3 and S4) were defined. The softening index of D. edulis fruits varied from 0.86±0.06 mm to 3.53±0.03 mm (edulis) and from 0.85±0.05 mm to 2.86±0. 04 mm (parvicarpa). This study reveals that the softening index is significantly different (p <0.05) from one variety to another. The contents of total polyphenols decrease significantly during the post-harvest softening and vary from 13.54±0.2 mg/g to 2.54±0.13 mg/g (edulis), then from 13.31±0.3 mg/g at 2.41±0.1mg/g (parvicarpa). The flavonoid contents decrease from 0.71±0.02 mg/100 g to 0.15±0.02 mg/g (edulis) and from 0.69±0.03 mg/100g to 0.12±0.02 mg/100 g (parvicarpa). The tannin content decreases significantly during softening but there is no significant difference between two varieties of safou at each softening stage. The inhibitory concentration of safou increases significantly to the threshold of 5% during post-harvest softening from one variety to another and no significant difference is observed. Correlation test showed that the softening stage is significantly correlated (p <0.05) with the parameters studied. No significant variation in the content of total oxalates of safou is observed from one variety to another while the phytate contents decrease significantly and the values are respectively 1.46±0.03 mg/100g at 0.35±0.02 mg/100 g (edulis) and from 1.43±0.01 mg/100g to 0.31±0.01 mg/100g (parvicarpa). The post-harvest softening greatly reduced the anti-nutritional contents in the safou pulp and this led to a loss of its nutritional value.
