“…The crude fiber content of date fruit varied between 1.71 to 2.77g/100g. The values were within the range (1.0-2.5g/100g) reported by Al-Harrasi et al (2014). Elsohaimy and Hafez (2010) reported a higher value of crude fiber (5.30 to 6.51 g/100g) whereas Sadiq et al (2013) reported lower value (0.50g/100g) of crude fiber content than the values obtained in present study.…”

The present investigation was conducted to evaluate the nutrient composition of four varieties of date fruit. The results of the study indicated that the variety Shamran had highest protein (2.77%) content and the variety Medjool the lowest (1.88%). Fat and crude fibre contents of date fruit varieties ranged from 0.17 to 0.50% and 1.71 to 2.22%, respectively. The variety Medjool had lowest amount of total soluble sugars (67.49g/100g) and reducing sugar (61.31g/100g). All the varieties of date fruit differed non-significantly among themselves for their non-reducing sugar content. The variety Khadrawi had the highest amount of starch content. Total dietary fiber (11.70g/100g) and soluble dietary fiber (3.34g/ 100g) were highest in variety Hillawi. All the four varieties of date fruit differed significantly from each other for their total dietary fiber content and soluble dietary fiber content. The varieties Khadrawi (8.46%), Hillawi (8.35%) and Shamran (7.94%) had significantly (p 0.05) higher insoluble dietary fiber as compared to variety Medjool (4.25%). The variety Shamran had highest amount of calcium (195.33mg/100g) and zinc (1.81mg/100g). The variety Medjool contained lowest amount of calcium (70.33mg/100g), iron (1.91mg/100g) and potassium (713mg/100g) while the highest amount of phosphorus (52.66mg/100g). A non-significant (p0.05) difference was observed in magnesium content of all the varieties. Polyphenol content of date fruits from different varieties ranged from 228.79 to 253.21 mg/100g.

Majhoul and Boufeggous date fruits, commonly grown in oases of Southern east Morocco, are widely consumed after post‐harvest season. Due to the perishability of date fruits, there is a need to extending their shelf life through cold storage. This study aimed to evaluate total soluble solids (TSS) content, moisture, acidity, color, firmness, as well as sensory attributes at 0, 1, 2, 3, and 5 months of cold storage for Majhoul and Boufeggous. Significant variations (p ≤ .05) in physico‐chemical attributes were observed during cold storage, but the two varieties did not behave similarly. The variation was more pronounced for Majhoul, especially for TSS, acidity, and Hunter‐color. Regarding sensory analysis, the stored samples were found to be less acceptable (p ≤ .05) with respect to mouthfeel, appearance, and color. Results obtained herein suggested that commercial cold storage (between +2°C and +4°C) should be seriously improved in order to retain overall quality of date fruits. Practical applications In the season of date (Phoenix dactylifera L.) harvest, production exceeds the market demand. Thus, most farmers store their production into cold stores in order to preserve intrinsic quality of the fruit until releasing into the market. This study will add current knowledge to the storage of date fruit and will provide an in depth insight on how cold storage can affect the acceptability of stored date fruits by consumers.

“…The date fruit is also an excellent source of potassium and high fiber content. Date pit constitutes 10 to 15% on an average mass of total date fruit (Al‐Harrasi et al, ). It contains 7.7%–12.5% oil on an average basis (Al‐Farsi & Lee, ).…”

The study was planned to formulate edible wax coating by utilizing date pit oil. Date pit oil was extracted from three date varieties (Aseel, Hallawi, and Dhakki) through solvent extraction method. One variety was selected on the basis of physicochemical analysis of date pit oil. The different treatments (T1, T2, T3, and T4) of wax coating were formulated by replacing water in standard wax formulation with date pit oil as 0.5%, 1%, 1.5%, and 2%, respectively. The storage studies were carried out for 16 days; different fruit parameters like pH, weight loss, total soluble solids (TSS), titratable acidity, fruit firmness, and vitamin C content were studied. Results indicated significant improvement in the shelf life of coated guava fruits as compared to uncoated guava fruits.T4 showed highest keeping quality as compared to T3, T2, and T1. Practical applications This research work is novel in the field of edible coating by using date pit oil as natural barrier against environmental factors affecting the shelf life of guava fruit. There is immense potential in this new commodity to explore more applications of promising importance. Moreover, this study can be replicated for other fruits and vegetables to curtail postharvest losses and supplementing economic benefits.
