Coffee silverskin extract protects against accelerated aging caused by oxidative agents
Nowadays, coffee beans are almost exclusively used for the preparation of the beverage. The sustainability of coffee production can be achieved introducing new applications for the valorization of coffee by-products. Coffee silverskin is the by-product generated during roasting, and because of its powerful antioxidant capacity, coffee silverskin aqueous extract (CSE) may be used for other applications, such as antiaging cosmetics and dermaceutics. This study aims to contribute to the coffee sector’s sustainability through the application of CSE to preserve skin health. Preclinical data regarding the antiaging properties of CSE employing human keratinocytes and Caenorhabditis elegans are col…
Simultaneous analysis of lysine, Nɛ-carboxymethyllysine and lysinoalanine from proteins
Protein quality was assayed by simultaneous measurement of lysine (Lys), carboxymethyllysine (CML) and lysinoalanine (LAL). GC-FID analysis of N-tert-butyl dimethylsilyl (tBDMSi) derivatives of these amino acids was undertaken. tBDMSi derivates were separated on a CP-SIL 5CB commercially fused silica capillary column (25 m × 0.25 mm i.d., 0.25 μm film thickness) employing a thermal gradient programmed from 200 to 300 °C. The identity of tBDMSi derivatives of Lys, CML and LAL was established by GC–MS while FID detection was employed for quantification. Analytical parameters such as linearity (lysine 350–4200 μM, LAL 3–81 μM, CML 16–172 μM), precision (1–13% variation coefficients), accuracy …
Patented and commercialized applications
Abstract The commercialization of high added-value compounds recovery from food wastes deals with several issues such as laboratory research, scale-up problems, protection of intellectual properties, and development of market-destined applications. These issues are described in this chapter wherein a collection of commercially available compounds recovered from food by-products is presented. Verification of market existing products matching with patented processes was conducted using patent applicant name in each case. However, this matching as well as production characteristics may not be correct in all cases, as most companies typically are secretive about their methods of production and …
