Abstract
Maillard reaction plays an important role in the flavour and color of some food. However, the excessive occurrence of Maillard reaction may affect the quality and safety of food. In this study, a simulated Maillard system composed of gluten and glucose was established to evaluate and analyze the regulatory role of tea polyphenols (TP) in it. The addition of tea polyphenols alleviated excessive browning of the Maillard reaction and significantly inhibited the accumulation of fructosamine and late glycosylation end products in the system. Based on the analysis of laser particle sizer and atomic force microscope, the large particle size distribution and aggregation structure of the Maillard reaction products in the tea polyphenol group disappeared. Further experiments showed that with the addition of tea polyphenols, the free radicals content in the system decreased, while the amount of reaction substrates increased. It was also shown that tea polyphenols effectively inhibited the isomerism of glucose to fructose and affected the content of free sulfhydryl and free amino groups in the system. The results indicated that tea polyphenols can regulate the Maillard reaction between gluten and glucose, which gives it the potential for application in the field of bakery and thermally processed foods.
期刊介绍:
LWT - Food Science and Technology is an international journal that publishes innovative papers in the fields of food chemistry, biochemistry, microbiology, technology and nutrition. The work described should be innovative either in the approach or in the methods used. The significance of the results either for the science community or for the food industry must also be specified. Contributions written in English are welcomed in the form of review articles, short reviews, research papers, and research notes. Papers featuring animal trials and cell cultures are outside the scope of the journal and will not be considered for publication.
