A kind of Lactobacillus plantarum strain jp-8 and application thereof

Abstract

The invention relates to a Lactobacillus plantarum strain JP-8 and a process for fermentation of sea asparagus puree by the strain to prepare ready-to-eat crisp chips. The strain is preserved in China General Microbiological Culture Collection Center on September 29, 2013 with a preservation number of CGMCC No.8289. The employed technical scheme includes: (1) using am MRS culture medium to prepare a Lactobacillus plantarum JP-8 seed bacterial liquid; (2) pulping sea asparagus, inoculating the seed bacterial liquid, and conducting anaerobic fermentation; and (3) preparing sea asparagus ready-to-eat crisp chips by means of material mixing, material spreading in a tray, hot air drying, microwave vacuum drying, and nitrogen-filled packaging. Through fermentation by the Lactobacillus plantarum, the quality (nutrition, flavor, shelf life and the like) of the sea asparagus ready-to-eat crisp chips is improved. According to the invention, hot air drying and microwave vacuum drying technologies are adopted successively, while the taste of the crisp chips is improved, and the flavor and nutrients of sea asparagus are reserved to the utmost, the production cycle is shortened, the energy consumption is reduced, and the production cost is lowered.

Description

technical field

[0001] The invention belongs to the technical field of food microbes and food processing, and in particular relates to a Lactobacillus plantarum strain JP-8 and a process for preparing ready-to-eat crisps by using the strain to ferment sea asparagus. Background technique

[0002] Sea asparagus, also known as salicornia, belongs to the Chenopodiaceae Salicornia genus and is an annual herbaceous halophyte. In my country, sea asparagus is mainly distributed around coastal tidal flats or saltwater lakes, including natural growth and artificial cultivation. There are more than 30 species of sea asparagus, but the currently commercially grown sea asparagus is mainly North American salicornia (Salicornia biggelowii). Sea asparagus is an alkaline plant, resistant to diseases and insect pests, no need to apply chemical fertilizers and pesticides, and its tender stems are a new type of pure natural organic health-care vegetables. Sea asparagus is rich in nutrition, r...
