“…These findings align with previous investigations conducted by [1,5,7,8,9,13,21,22,37,41,43] reporting protein content in date seeds ranging from 4.8 to 12.5%. Date seeds are known to contain water-soluble proteins like globulin, albumin, prolamin, and glutelin [35]. Furthermore, the protein content in Yemeni coffee (10.95%) closely resembles the findings reported by [38].…”

The study aimed to investigate the chemical composition of three widely available types of date seed in the Yemeni market (Iraqi, Saudi, and Yemeni) and their potential use as caffeine-free coffee alternative. Quantitative estimation was conducted for moisture, ash, protein, fiber, fat, carbohydrates, and caffeine, along with a descriptive estimation for alkaloids, tannins, and resins. Date seed coffee was prepared and sensory evaluation was performed by trained panelists. The results showed that Yemeni date seeds had the highest extraction Rate on average (30%), while Saudi date seeds had higher moisture, protein, fat, and fiber contents on average (8.997, 6.897, 11.167, and 16.333%, respectively). Yemeni date seeds contained the highest carbohydrate content on average (58.290%). All tested date seeds were caffeine-free, while the chemical composition for Yemeni coffee were 7, 0.9, 13.9, 14.4, 12.8, 4.1, and 1.5% for moisture, ash, protein, fat, fiber, carbohydrates, and caffeine, respectively. Descriptive estimation results showed the absence of alkaloids in all date seeds and coffee samples, with the presence of both tannins and resins. For sensory evaluation indicated high values for all attributes of date seeds coffee alternative, with Saudi date seeds coffee outperforming other types, suggesting its potential use as a caffeine-free coffee alternative and its associated health benefits.

“…In the case of 10% DSP, peroxide values were similar to or slightly lower than the control group, displaying fluctuations throughout the storage period. compared to the control group during the 15-day storage period (Al-Khalili et al, 2023). The varying patterns in peroxide values across all levels and the control group indicate the need for further investigation to determine the effect of DSP on the oxidative stability of chicken burgers during storage.…”

The main objective of this study is to explore the potential use of date seed powder in improving the oxidative stability of some meat products; beef and chicken burgers. The phytochemical analysis of date seed powder revealed its significant antioxidant potential, including high DPPH scavenging activity (81.38%), low IC50 value (0.59 mg/mL), and substantial levels of phenolics (2.53 mg/g), flavonoids (1.37 mg/g), saponins (287 mg/100g), and anthocyanins (238 mg/100g). These properties, attributed to phenolics content, position date seed powderas a valuable source of natural antioxidants. When assessing the impact of date seed powder (DSP) supplementation on the oxidative stability of beef and chicken burgers, distinct outcomes were observed. Beef burgers with 1 to 10% DSP exhibited consistently lower peroxide values, indicating improved oxidative stability. On the contrary, chicken burgers showed varied peroxide values across all DSP concentrations (1, 3, 5, 7, and 10%). The Thiobarbituric Acid (TBA) values of beef and chicken burgers with varying DSP concentrations also displayed divergent trends. Specifically, the 3 and 10% DSP beef burger samples showed potential for maintaining or enhancing oxidative stability. Conversely, the influence of DSP addition on chicken burgers' oxidative stability varied across different concentrations. In this context, the findings suggest that DSP has the potential to improve the oxidative stability of beef burgers, while its impact on chicken burgers remains inconclusive.

“…Accumulated evidence from the literature indicates that the high antioxidant activities of date seeds (DS) are attributed to their richness in polyphenolic compounds. 134,171 Thus, date by-products could be explored as a source of natural preservatives with potential applications in the pharmaceutical, medical, and food industries. Pharmacological, nutritional, and clinical evidence has positioned polyphenols as novel natural bioactive compounds, garnering attention from researchers for various health and industrial applications owing to their established antioxidant properties.…”

“…Some of the potential applications of date seeds in their natural and modified forms in different food sectors are presented in Table 2. The utilization of date seeds (raw, roasted, powdered, and defatted) and their secondary products, such as dietary fiber, and oils, has been reported by researchers in bakery and confectionery, 132,133 beverage, 134 meat, dairy, and among the major industrial food sectors (Fig. 3).…”
