Development of a Triticale‐Based Amylolytic Biocatalyst for Starch Hydrolysis With Applications in Brewing Wort Sugar Enhancement

Food Bioengineering, Volume 4, Issue 3, Page 305-317, September 2025.
Co‐immobilization of α‐amylase and β‐amylase from triticale malt in cross‐linked gelatin improved kinetic parameters and achieved over 100% immobilization efficiency. The triticale malt‐based α‐amylase and β‐amylase biocatalyst enhanced reducing sugar release in barley wort by 11.8 g/L in the first cycle and retained 5.8 g/L after five reuse cycles ...

The derivation of the formyl-group oxygen of chlorophyll b in higher plants from molecular oxygen. [PDF]

, 1994
The mechanism of formation of the formyl group of chlorophyll b has long been obscure but, in this paper, the origin of the 7-formyl-group oxygen of chlorophyll b in higher plants was determined by greening etiolated maize leaves, excised from dark-grown

Comparative Studies on the Structure and Biological Activities of Two New Polysaccharides From Tricholoma flavovirens (TF‐P) and Trametes versicolor (TV‐P)

Food Frontiers, Volume 6, Issue 5, Page 2437-2455, September 2025.
Two water‐soluble polysaccharides were isolated and purified from Tricholoma flavovirens (TF‐P) and Trametes versicolor (TV‐P), respectively. The structures of the two polysaccharides were identified by combining GPC, FT‐IR, HPLC, GC–MS, and NMR, and the structure–activity relationship has also been studied using immune cells and tumor cells. TV‐P with
