Long shelf life fermented pickled vegetable and preparation method thereof

Abstract

The invention relates to long shelf life fermented pickled vegetable and a preparation method thereof, which belong to the technical field of picked fermented foods. The preparation method comprises the following steps: using tuber mustard as the raw material; slicing, picking, softening and then packaging the tuber mustard in a picked vegetable jar; filling ferment agent prepared by mixing 3-5 percent of Lact.Plantarum and Lact.Casei according to the proportion of 1:1 and salt water with 4-6 percent of salt content; fermenting for 48h under the temperature of 20-30 DEG C; ending the fermentation until the acidity of the fermented solution reaches 0.45-0.55 percent; dehydrating, seasoning and embrittlementing; packaging by using laminated film bags and sterilizing for 15min under the temperature of 70 DEG C. The preparation method basically keeps the fermented picked vegetable pure, tender and crisp, salubrious and tasty, the fermented picked vegetable has the basic characteristics of separating fat and stimulating the appetite, promoting the digestion, and the like, and can be kept for more than six months under the normal temperature. The invention can be popularized and applied to the vegetable processing industry.

Description

technical field

[0001] The invention relates to the technical field of salted fermented food, in particular to a fermented mustard pickle with a long shelf life and a preparation method thereof. Background technique

[0002] China is the world's largest producer of vegetables and there are many varieties of processed vegetables. Among them, the most traditional and the largest vegetable products are pickled vegetables. Pickled vegetables originated in the Zhou Dynasty and have a history of more than 3,000 years. With the improvement of processing technology, pickled products are increasing, among which kimchi is famous for its unique flavor. It uses seasonal vegetables as raw materials, and is fermented and soaked in pickling liquid by lactic acid bacteria. The history of Chinese kimchi can be traced back to more than 2,000 years ago. With its fresh and pure, crisp and fragrant, refreshing and delicious, natural color, mellow and long-lasting, greasy and appetizing, promot...
