Embodiment 1

[0029] A method for preparing dried bamboo shoots, comprising the steps of raw material pretreatment, soaking, fermentation with compound lactic acid bacteria, microwave vacuum drying, baking, and packaging;

[0030] Wherein, the compound lactic acid bacteria are Lactobacillus plantarum and Lactobacillus germanus. The specific operation can adopt the conventional operation of the prior art.

Embodiment 2

[0032] In this example, on the basis of Example 1, the process parameters are further optimized: the inoculation amount of compound lactic acid bacteria fermentation is 2-4%, the fermentation temperature is 30-35°C, and the fermentation time is 48-72h. The fermentation efficiency and the quality of the finished product Higher, including indicators of lactic acid content and crude fiber content.

Embodiment 3

[0034] A method for preparing dried bamboo shoots, comprising the steps of raw material pretreatment, soaking, fermentation with compound lactic acid bacteria, microwave vacuum drying, baking, and packaging;

[0035] Wherein, the compound lactic acid bacteria are Lactobacillus plantarum and Lactobacillus germanus.

[0036] Further, the liquid-solid ratio of the complex lactic acid bacteria fermentation is 1.

[0037] The Lactobacillus plantarum is Lactobacillus plantarum 550.

[0038] The soaking adopts salt water soaking, and 8% dried hawthorn is also added in the salt water, wherein the mass ratio of water and salt in the salt water is 1:1.4, and the mass ratio of salt water and bamboo shoots is 5:2.

Abstract

The invention discloses a preparation method of dried bamboo shoots, and belongs to the technical field of food processing. The method comprises the steps of raw material pretreatment, digestion, compound lactobacillus fermentation, microwave vacuum drying, baking and packaging. Compound lactobacillus includes lactobacillus plantarum and German-style lactobacillus. Compared with an existing dried bamboo shoot processing method, the compound lactobacillus is inoculated for fermentation, the color protecting and flavoring effects are achieved by adding hawthorn, gradual drying in the two modes of microwave vacuum drying and baking is adopted finally, water is removed more thoroughly, the dried bamboo shoots have the baking fragrance, the color is more attractive, and the dried bamboo shoots have the advantages of being low in crude fiber content and rich in nutrition.

Description

technical field [0001] The invention relates to a preparation method of dried bamboo shoots, belonging to the technical field of food processing. Background technique [0002] Dried bamboo shoots not only assist famous dishes, but also have considerable nutritional and medicinal value. The nutritional content of dried bamboo shoots is determined by the Nanjing Forestry Chemical Research Institute. The bamboo shoots contain 2-4% sugar, 0.2-0.3% fat, 2.5-3% protein, and contain 18 kinds of amino acids such as cystine and glutamic acid and polysaccharides. The content of multivitamins and carotene is more than double that of Chinese cabbage; and the protein of bamboo shoots is superior, which is an excellent health-care vegetable. According to medical research, because dried bamboo shoots contain a variety of vitamins and cellulose, they have anti-cancer and anti-cancer effects. Fat people can also promote digestion after eating bamboo shoots, which is a good product for obes...
