The influence of processing sequence and frozen storage on the seasoned alaska pollack (Theragra chalcogramma) roe product quality

Theragra chalcogramma Hydrolysate, Rich in Gly-Leu-Pro-Ser-Tyr-Thr, Alleviates Photoaging via Modulating Deposition of Collagen Fibers and Restoration of Extracellular Components Matrix in SD Rats

“…Although many foodderived peptides with anti-photoaging properties have been reported, little information about the Theragra chalcogramma processing by-product was available until now. As a commercially important fish species in China and throughout the world, the biomass of processing by-products from Theragra chalcogramma is increasing, and only a few works in the literature about the peptides' release from Theragra chalcogramma exist so far [21][22][23], and no information on the anti-photoaging effects of Theragra chalcogramma hydrolysates is available. Therefore, in the present study, we aimed to prepare the hydrolysate with potent photoaging prevention from the discarded industrial processing by-product of Theragra chalcogramma (TCH, rich in low-molecular-weight peptides) by enzymatic proteolysis, and then to further clarify the underlying mechanism.…”
