Anacardium plants: Chemical,nutritional composition and biotechnological applications
Anacardium plants are native to the American tropical regions, and Anacardium occidentale L. (cashew tree) is the most recognized species of the genus. These species contain rich secondary metabolites in their leaf and shoot powder, fruits and other parts that have shown diverse applications. This review describes the habitat and cultivation of Anacardium species, phytochemical and nutritional composition, and their industrial food applications. Besides, we also discuss the secondary metabolites present in Anacardium plants which display great antioxidant and antimicrobial effects. These make the use of Anacardium species in the food industry an interesting approach to the development of green foods.AK.

Stirred-type yoghurt incorporated with sour cherry extract in chitosan-coated liposomes
Yücetepe, Aysun ( Aksaray, Yazar )Liposomal systems are promising carrier systems for the delivery of phenolic compounds. However, the commercial usage of aqueous liposomal dispersions is still challenging. In this study, an aqueous liposomal dispersion which was loaded with sour cherry phenolics (SCE) were converted into powder form by spray drying to make the use of such delivery systems industrially applicable. Then, the obtained SCE loaded liposomal powder was incorporated into a stirred-type yoghurt system. During 21-day storage at 4 °C, sensorial and physicochemical properties such as pH, color, and whey syneresis of yoghurt with SCE loaded liposomal powder were investigated. According to the results, SCE was successfully encapsulated in aqueous liposomal dispersion and spray dried. Spray drying process did not degrade phenolic compounds that were encapsulated by liposomes. The structure of liposomes in the sample contained spray dried liposome encapsulates with SCE (Y-encapsulated SCE) was the most stable in yoghurt during storage which also affects the stability of SCE. Thus, SCE showed the lowest degradation level in this sample among all samples in terms of total phenolics and antioxidant capacity. This means that the SCE in yoghurt with liposomal encapsulates was protected during the storage period. The spray drying process also led to an increased total dry solid and reduced syneresis. Although syneresis of yoghurt containing liposomal powder with SCE and without SCE was the lowest, control yoghurt was chosen to be the best according to the sensorial evaluation
Recovery of Polyphenols Using Pressurized Hot Water Extraction (PHWE) from Black Rosehip Followed by Encapsulation for Increased Bioaccessibility and Antioxidant Activity
In this work, pressurized hot water extraction (PHWE) of hydrophilic polyphenols from black rosehip fruit was maximized using response surface methodology for simultaneous optimization in terms of extraction yield, total antioxidant capacity, total (poly)phenols, catechin, total monomeric anthocyanins, and cyanidin-3-O-glucoside. Extraction parameters, including temperature (X1: 40–80 °C) and the solvent-to-solid ratio (X2: 10–40 mL/g), were investigated as independent variables. Experimentally obtained values were fitted to a second-order polynomial model, and optimal conditions were determined using multiple regression analysis and analysis of variance. The black rosehip extract (BRE) obtained at optimized PHWE conditions was further encapsulated in biopolymer-coated liposomes and spray dried to enhance its processing and digestive stability. After reconstitution, the fabricated particles had an average size of 247–380 nm and a zeta-potential of 15–45 mV. Moreover, encapsulation provided remarkable protection of the phenolics under in vitro gastrointestinal digestion conditions, resulting in up to a 5.6-fold more phenolics in the bioaccessible fraction, which also had 2.9–8.6-fold higher antioxidant activity compared to the nonencapsulated BRE. In conclusion, PHWE in combination with a biopolymer coating is a potent method for the production of stable and safe edible natural extracts for the delivery of (poly)phenolic compounds in food and dietary supplements

Assessment of Biochemical Composition and Antioxidant Properties of Algerian Date Palm (<i>Phoenix dactylifera</i> L.) Seed Oil
Date palm (Phoenix dactylifera L.) trees are largely cultivated across the Algerian oases; they are principal sources of remuneration and the economic basis for residents of these areas. Date palm fruits are rich sources of essential nutrients, vitamins, minerals, and dietary fibers, with many potential health benefits, yet there are few studies on the chemical composition and biological properties of date palm seed oil. In this study, we present an in-depth characterization of the biochemical composition and antioxidant properties of date palm seed oil (DPSO) produced in Algeria. DPSOs of eight Algerian cultivars, Arechti, Degla-Baida, Deglet-Nour, Ghars, Haloua, Itima, Mech-Degla, and Tentbouchet, were investigated to determine their biochemical compositions and antioxidant properties. The results highlight the potential of DPSO as an alternative food and a natural resource, thanks to several important compounds having high antioxidant capacity. In particular, fatty acids and triacylglycerol (TAGs) analyses showed that oleic (42.74–50.19%), lauric (18.40–22.2%), and myristic (8.83–10.17%) were the major fatty acids, while 1-myristoyl 2-oleoyl 3-linoleoyl glycerol, 1-linolenoyl 2-oleoyl 3-linoleoyl glycerol, 1-2-linolenoyl 3-linoleoyl glycerol, and 1-linolenoyl 2-myristoyl 3-linoleoyl glycerol were the major TAGs. Biophenols and tocopherols analyses revealed the presence of important compounds, such as catechin (22.04–24.92 mg/kg), vanillin (10.67–23.98 mg/kg), and α-tocopherol (443.59 mg/kg), at high remarkable levels. Therefore, a comparison with the literature data concerning other seed oils, including olive oil, confirms that DPSO can be considered a high-quality oil, from a biochemical and biological point of view

Antioxidant, Antimicrobial, and Anticancer Effects of Anacardium Plants: An Ethnopharmacological Perspective
Anacardium plants have received increasing recognition due to its nutritional and biological properties. A number of secondary metabolites are present in its leaves, fruits, and other parts of the plant. Among the diverse Anacardium plants' bioactive effects, their antioxidant, antimicrobial, and anticancer activities comprise those that have gained more attention. Thus, the present article aims to review the Anacardium plants' biological effects. A special emphasis is also given to their pharmacological and clinical efficacy, which may trigger further studies on their therapeutic properties with clinical trials.AJ acknowledged the funding from Uttarakhand council for Biotechnology, Pantnagar, Uttarakhand, India (File No. UCB/R&D Project/2018-311) for this work.
