In recent years there has been an extensive search for nature-based products with functional potential. All structural parts of (bladder cherry), including fruits, pulp, and less-explored parts, such as seeds and peel, can be considered sources of functional macro- and micronutrients, bioactive compounds, such as vitamins, minerals, polyphenols, and polyunsaturated fatty acids, and dietetic fiber. The chemical composition of all fruit structural parts (seeds, peel, and pulp) of two phenotypes of were studied.

The present paper aims to investigate the chemical composition of unripe black pine seeds obtained from Bulgaria. The lipid fraction was evaluated in unripe seeds, and the cellulose, total carbohydrates, glucose, fructose, and sucrose were evaluated in seedcakes. The major fatty acid identified in the seed oil was unsaturated linoleic acid (44.

Fruits contain a number of useful substances including antioxidants. Their bio-accessibility after passing through the digestive tract is of primary importance when considering their benefits. In this respect, we investigated the effect of in vitro digestion on the phytochemicals of eight fruit juices.

Exploring the chemical composition and biological activity of different fruit varieties is essential for the valorization of their health claims. The current study focuses on a detailed comparative analysis of three early- and two mid-ripening peach varieties: "Filina" (peach), "July Lady" (peach), "Laskava" (peach), "Gergana" (nectarine), and "Ufo 4" (flat peach). They were characterized in terms of essential nutrients such as carbohydrates (sugars and dietary fibers), amino acid content, and lipids as well as mineral content, fat-soluble vitamins, carotenoids, and chlorophyll.

The interest in carob pod as an ingredient of functional foods is constantly increasing due to its beneficial health effect and functional properties. The aim of this study was to evaluate the chemical composition and antioxidant potential of carob seeds, as well as the functional properties of its isolated galactomannan fraction. The lipid, protein, carbohydrate and phenolic composition were analysed.

Article Synopsis
  • * PI shows a higher crude protein content (72.84%) and a greater concentration of total phenols compared to PI, which holds 68.67% crude protein.
  • * The solubility of PI ranges significantly with pH, while PI has lower solubility; adding NaCl affects their solubility differently, with PI's solubility increasing notably under certain conditions.

Members of the bacterial genus are known as producers of a broad spectrum of antibiotic compounds of proteinaceous nature that possess inhibitory activity against different saprophytic and pathogenic microorganisms. In the current research, a peptide synthesized by strain BM47, previously isolated from a natural thermal spring in Bulgaria, was identified and characterized as a bacteriocin. antimicrobial screening of the crude bacteriocin substance of BM47 showed activity against the plant pathogenic fungi , , sp.
