Particle size is an essential concept in flour milling which influences dough rheological properties and food product quality. The grape seeds flours (GSF) obtained by further grinding grape seeds vary in particle size and differ in chemical composition. Grape seeds selected from red wine pomace and wheat flour of a low extraction rate of 480 type were used in samples formulation. The objective of this work was to investigate the influence of different particle sizes and addition levels of grape seeds flour (GSF) ...

The skin is covered with a hydrolipid film that, depending on the area of the body, comprises secretions from sebaceous glands and from apocrine and eccrine sweat glands. Decomposition products from corneocytes and cornification (cellular debris and stratum corneum lipids) in the process of being shed are also present. This film provides a natural defense against pathogenic organisms but also attracts dirt and pollutants from the environment. Thus, periodic cleansing to remove debris, dirt, and odor is essential t...
