Photo-induced glycosylations of trichloroacetimidate donors and alcohols using an edible polyphenol, curcumin, were examined under visible photo-irradiation (470 nm). It was found, for the first time, that these glycosylations proceed smoothly under mild reaction conditions to give the corresponding glycosides in high yields. In addition, the present glycosylation method was applicable to a wide range of trichloroacetimidate donors and alcohol acceptors and showed high chemoselectivity over glycosyl phosphite, phosphate, (-phenyl)trifluoroacetimidate, fluoride, glycal and thioglycoside.

Baru (Dipteryx alata Vogel), a fruit native to the Brazilian Cerrado, has gained scientific interest due to its nutritional potential and commercial value. Its edible seed, of high commercial value, represents around 5 % of the fruit. On the other hand, its pulp, a byproduct of the baru processing industry, is normally discarded, generating a huge volume of waste with reported antioxidant properties.

Background: Traditional methods for fabricating protein-polyphenol conjugates have not preserved the structural and functional integrity essential for the food industry effectively. This research introduces an advanced encapsulation methodology designed to overcome these limitations, with the potential to enhance the stability of edible oil matrices significantly, leading to improved preservation techniques and extended shelf life.
Results: Glycated pea protein isolate-curcumin conjugates (gPPI-CUR) were developed, demonstrating a marked improvement in the oxidative stability of walnut oil (WO), a proxy for edible oil matrices.

This study evaluates the microencapsulation of peanut skin phenolic compounds by spray drying, assessing their physicochemical properties and storage stability and the protective effect against oxidative deterioration in walnut kernels. Extraction yield, total phenolic content, and HPLC-ESI-MS/MS analysis were performed on peanut skin crude extract (PCE). Microencapsulation of PCE with 10%, 20%, and 30% maltodextrin via spray drying was conducted.
