Abstract

The invention discloses a GABA-rich yogurt and a preparation method thereof. The yogurt comprises the following components in mass percentage: 80-95% of milk or reconstituted milk, 0.1-10% of sweetener or white granulated sugar, 0.1-1% of sodium glutamate, 0.1-10% of compound bacterial agent, concentrated The protein powder is 0.5-5%; the mass ratio of Lactococcus lactis subsp. lactis and Streptococcus thermophilus in the compound bacterial agent is 1-10:90-99. In the present invention, a compound bacterial agent is prepared by mixing high-yielding GABA strains in a certain proportion, and through a specific fermentation process, the GABA content in the fermented yogurt is doubled and can reach 450 mg / g; the obtained yogurt has a rich frankincense and a thick texture. Thick, delicate taste and rich in nutrition, on the premise of ensuring healthy and delicious, it can play a functional effect of decompression and soothing. The preparation method of the invention has simple process, convenient operation and low production cost, and is suitable for large-scale factory fermentation production.

Description

technical field [0001] The invention relates to the technical field of fermented foods, in particular to a GABA-rich yogurt and a preparation method thereof. Background technique [0002] Gamma-aminobutyric acid (GABA) is a non-protein amino acid widely distributed in nature. In vivo, it is converted from glutamic acid by glutamic acid decarboxylase. It is an important inhibitory neurotransmitter that has been deeply studied. It participates in various metabolic activities in the body and has many physiological functions, such as lowering blood pressure, Improve brain function, sedation, enhance long-term memory, liver and kidney functions and other functions. The research and development of GABA-rich foods has become a hot spot in foreign research. GABA is widely used in food, medicine and other fields, including plants (rice germ, rice bran, green tea, pumpkin, soy products, tomatoes, chlorella, etc.), Foods of GABA derived from microorganisms (lactic acid bacteria, yeas...
