Abstract

The invention discloses a method for making a fermented crystal crisp sweet bamboo shoot. According to the prepared bamboo shoot, low-salt curing and low-temperature slow freezing are conducted, two kinds of lactic acid bacteria are added for fermentation, seasoning, packaging and sterilization are conducted on the fermented bamboo shoot, and then the fermented crystal crisp sweet bamboo shoot which is crisp, refreshing, bright in color and lustre, rich in nutrient, unique in flavor, convenient to carry and capable of being eaten instantly is obtained. Due to the fact that low-salt curing, low-temperature slow freezing and fermentation are conducted, the original bright green color, the nutritive value and the crisp and refreshing taste of the bamboo shoot are reserved, the bamboo shoot and other auxiliary materials are fermented fully, and thus the quality and the flavor of the bamboo shoot are improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing fermented crystal crispy bamboo shoots. Background technique [0002] Bamboo shoots have been regarded as "treasures in dishes" in China since ancient times. Bamboo shoots are a traditional Chinese delicacy with a crisp taste and a very long history of eating and cultivation. In terms of nutrition, bamboo shoots are rich in protein, amino acid, fat, sugar, calcium, phosphorus, iron, carotene, vitamin B1, B2, and C. The content of multivitamins and carotene is more than double that of Chinese cabbage; and the protein of bamboo shoots is superior, containing lysine, tryptophan, threonine, phenylalanine necessary for the human body, and in the process of protein metabolism Glutamic acid and cystine, which play an important role in maintaining protein configuration, are excellent health-care vegetables. Bamboo shoots are not only rich in various nutrients, but...
