Abstract:

<em>In this study, the effects of the grape seed powders and extracts of from two different grape cultivars (Razakı and Siyah Gemre) on the quality characteristics of Turkish sausage were investigated during the ripening period. Some characteristics of Turkish sausage including phenolic content, radical scavenging, hydrogen peroxide scavenging, Fe<sup>+2 </sup>chelating activity, Inhibition of Escherichia coli, Staphylococcusaureus, Candida albicans were studied. In fermented sausage, grape seed powders and extracts demonstrated the greatest inhibitory activity against Staphylococcus aureus. F

Abstract:

Grape seeds are agro-industrial by-products, which if improperly managed, may be responsible for socioeconomic and environmental problems. Nevertheless, it is possible to effectively valorize them by means of extraction of the bioactive compounds, especially the antioxidant phenolic molecules, using a safe, green, and environmentally-friendly extractive medium (i.e., hydro-glyceric solution). In the present study, the extraction was performed using seeds from two Lebanese varieties, Obeidi and Asswad Karech, and three international varieties, Marselan, Syrah, and Cabernet Franc.

Abstract:

Camu camu (Myrciaria dubia) is a fruit from the Peruvian Amazon, highly valued for its high content of vitamin C, which is concentrated in its pulp. Due to this nutritional characteristic, it is processed into juices and extracts. However, its industrialization generates a considerable amount of waste. Therefore, its utilization is vital to reduce environmental pollution. The content of phenolic compounds in the peel and seed of camu camu has been studied, indicating that factors such as drying temperature and the method of stabilizing the concentrated powder are key to preserving its antioxid
