Guava-ganoderma lucidum biological beverage and preparation method thereof

Abstract

The invention discloses a guava-ganoderma lucidum biological beverage and a preparation method thereof. The preparation method comprises the following steps: adding ganoderma lucidum mycelium pellet culture into guava contained fruit juice for fermentation, thereby obtaining the guava-ganoderma lucidum biological beverage; and fermentation conditions are as follows: temperature: 28 DEG C + / - 2 DEGC, pressure: 0.25-0.35 MPa, agitation speed: 100-200 r / min, the volume of liquid: 50-70% of the tank volume, ventilatory capacity: 1 / 5-3 / 5 of the tank volume / min, and culture: 3-10 days. According tothe invention, the ganoderma lucidum mycelium pellets are utilized for deep fermentation of the fruit juice, thus increasing contents of ganoderma lucidum active ingredients, proteins, essential amino acids and vitamins in the product, and making the guava-ganoderma lucidum biological beverage unique in flavor and soft and elastic and fine and smooth in mouthfeel; and the product has nutrition and health care effects on the human body, making up for the deficiency of nutritional factors of the fruit juice.

Description

technical field [0001] The invention mainly relates to the fields of biotechnology and beverage and food technology, in particular to a guava ganoderma biological drink and a preparation method thereof. Background technique [0002] Juice is a kind of leisure food with wide consumer groups and large consumption. But traditional fruit juice is made with fresh fruit juice or fresh fruit juice with water and table sugar etc., and functional variety is less. Therefore, it is necessary to develop new functional juice products to meet the needs of different consumer groups. [0003] Guava is a tropical and subtropical fruit. It is native to the United States. Now it is cultivated in South China and the Sichuan Basin. It is sweet and delicious. Guava tastes sweet and juicy, with smooth flesh and less core. It is rich in nutrients, especially high in protein and vitamin C. In addition, it also contains vitamin A, vitamin B and trace elements calcium, phosphorus, iron, Potassium, ...

AI Technical Summary

Problems solved by technology

However, wild Ganoderma lucidum resources are scarce; the period of planting Ganoderma lucidum is long, covers a large area, and is affected by seasons

Therefore, the cost of raw materials is high

In addition, traditional Ganoderma lucidum is used as medicine with fruiting bodies or spores, the former is highly fibrous and lignified, and has a strong bitter taste; the latter has low yield and thick cell walls

Therefore, both are not suitable for direct use as food raw materials.
