Abstract

The invention discloses a preparation method of a corn germ protein beverage modified by Maillard reaction, and belongs to the technical field of vegetable protein. The method comprises the followingsteps: taking corn germ meal, a byproduct after oil extraction, as a raw material, extracting corn germ protein by an alkali-dissolving and acid precipitation method, preparing a Maillard reaction product of corn germ protein by reacting with reducing sugar, and mixing the reaction product with concentrated juice, various food additives, drinking water to obtain the corn germ protein beverage modified by the Maillard reaction. This beverage comprises, in parts by mass, 5-10 parts of a Maillard reaction modified product of corn germ protein, 5-10 parts of concentrated juice, 3.5-5 parts of white sugar, 0.5-1 part of an acidulant, and 0.1-0.3 part of a compound stabilizer, 0.05-0.1 part of an emulsifier and the balance drinking water. The preparation process of the Maillard modified proteinbeverage is simple, no other chemical reagents are added, the safety is high, the yield of the Maillard modified product is high, and method is high in operability and suitable for large-scale food industrial production.

Description

technical field [0001] The invention relates to a functional beverage, in particular to a preparation method of a Maillard reaction modified corn germ protein beverage. It specifically relates to a method for producing a novel corn germ protein beverage by using Maillard reaction with reducing sugar, and belongs to the field of food. Background technique [0002] Corn germ protein has good nutritional properties, and its Maillard reaction product has good functional properties such as solubility, emulsification and antioxidant activity. The corn germ protein is used as a raw material, and the maillard reaction is carried out with reducing sugar to prepare the corn germ protein powder modified by the Maillard reaction. In recent years, many scholars have studied the preparation, functionality and stability of various compound protein drinks, and believe that compound protein drinks can better meet the balance of amino acid composition required by people, have more comprehens...
