| Outline of Final Research Achievements |
Reducing food losses and waste is an increasing global interest. We previously found that fluorescent substances were produced from 3-O-methylgallate (3-MGA) by a non-biological process. In this study, we examined a simple method for transforming proteins in food into fluorescent substances via a chemical reaction using 3-MGA. Fluorescent substances were produced effectively by incubation of 3-MGA and Tryptone at neutral pH at 28 C for 2 days. The antioxidants inhibited the production of fluorescent substances, but other food ingredients showed no inhibition. The incubation of 3-MGA with pancreatic hydrolysates of several proteins also produced fluorescent products. Finally, the incubation of 3-MGA with pancreatic hydrolysate of crude caseins prepared from commercial milk produced fluorescent substances. The simple transformation will contribute to the development of new basic techniques for the effective utilization of proteins in food losses and waste.
