## 1 Introduction  
Dates, or _Phoenix dactylifera_ L, are widely consumed in northern Africa and the Middle East area in addition to diverse regions including Central and South America and Europe (the southern part) (FAOSTAT, 2022). Due to their high quantities of sugar, dietary fiber, macronutrients, and minerals, dates have long been deemed by Middle Easterners as the ideal meal supplement [1]. The sweetness and texture of dates are influenced by their adulthood and mellowness stage [2]. Dates are normally picked and sold in three developmental stages: aged hard (Besser or Khalal), demi-seasoned (Rutab), and seasoned (Tamr). In addition to their nutritional estimate, dates are associated with a number of bioactive effects, i.e., antioxidant, anti-mutagenic, anti-inflammatory, anti-tumor, anti-bacteriological, and immunositulant [3, 4]. It is believed that the polyphenols in dates, containing hydroxycinnamates, phenolic acids, flavonoid glycosides, and proanthocyanin oligomers, contribute to their beneficial properties [5]. Numerous polyphenols contained in date fruits, including pellargonin and derivatives of cinnamic acid, have been demonstrated to enhance cellular resistance recently [6]. However, these substances are unstable. Microencapsulation techniques in this case might aid in stabilizing polyphenols for use in industrial applications. By protecting bioactive substances from O2, H2O, light, and other environmental variables, microencapsulation increases their stability and converts liquid solutions into powders for easier handling [7]. Dates are popular treats that are sold in a range of cuisines due to their added nutritional value. However, between 12 and 15% of dates contain stones that are often regarded as the fruit's by-product and are not yet commercially valuable [2]. Bedouin tribes used to consume roasted date seed infusions, but most societies have not really used them to date, even though date stones contain superior polyphenic quantities and outstanding antioxidant effects. Abundant research on animals shows biological advantages, such as a decrease in oxidative impairment, progress in memory and conception deficiencies in Alzheimer's patterns, and anti-diabetic effects [8]. Given the importance of dates as a dietary component and the emerging benefits of eating raw fruit for health, further in-depth study of date seed biochemical composition is desirable. On the other hand, one of the most significant issues facing people today is obesity, which is linked to several metabolic disorders like diabetes mellitus and cardiovascular disease. Recently, it has become more common among Eastern children and teenagers [9]. Recently, dietary fibers extracted from dates which were integrated into biscuit models showed anti-obesity features in animal models by controlling their lipid outline, kidney, blood sugars, and liver activity [10]. Date palm pits from the Kentichi type had a strong inhibitory impact against key enzymes linked to diabetes and obesity, showing its ability to be used in the agro-food, cosmetic, and pharmaceuticals industries instead of synthetic additives [11]. The processes behind the anti-obesity benefits are still not completely known. In detail, it has been suggested that the anti-obesity characteristics result from the regulation of the manifestation of lipogenic enzymes in the liver and pale adipose matter [12] as well as the reticence of \(\alpha\)-glucosidase in the starch assimilation in the presence of purple corn's anthocyanins [13], which might be occurring in the presence of date seed polyphenols. By accumulating tri-acylglycerols or circulating free fatty acids (FFAs) in response to variations in vitality demands, adipocytes are crucial for retaining lipid homeostasis and strength equilibrium. Since both adipocyte hyperplasia and hypertrophy can result in increased adipose tissue mass, the creation and characteristics of adipocytes have been the emphasis of obesity investigations [14]. Adipogenesis is a multifaceted process.
