Abstract

The invention discloses a preparation process for wet rice vermicelli with a long shelf life. The process includes: draining soaked rice and then conducting crushing to obtain rice vermicelli, adding ginger essential oil accounting for 0.1-0.5 per thousand of the weight of the rice vermicelli and cinnamon oil accounting for 0.1-0.2 per thousand of the weight of the rice vermicelli into the obtained rice vermicelli, mixing them uniformly and carrying out squeezing molding, and subjecting the obtained vermicelli to aging, water bath, subpackaging, and sterilization, thus obtaining the wet rice vermicelli. Compared with the prior art, by adding an antistaling agent composed of ginger essential oil and cinnamon oil into the crushed rice vermicelli in the invention, the prepared wet rice vermicelli has a shelf life of 90 days at room temperature, and the wet rice vermicelli within the shelf life can maintain the taste and quality of fresh wet rice vermicelli. In addition, as the added antistaling agent is a natural plant extract, people can eat the wet rice vermicelli with assured safety.

Description

technical field [0001] The invention relates to a processing technology of rice noodles, in particular to a preparation technology of wet rice noodles with a long shelf life. Background technique [0002] Wet rice noodles are processed by pressing and forming the rice noodles obtained by soaking and refining rice. The characteristic flavor and taste of wet rice noodles are recognized by rice noodle eaters, but the retention period of wet rice noodles is short, which has become a constraint. An important bottleneck for its long-distance sales. In the prior art, the purpose of prolonging the shelf life of wet rice flour is reached by adding antiseptic and bactericide in the production process usually, such as the invention patent of CN1231837 with the publication number, by adding anti-starch aging agent (which can be oligosaccharides) in the production process , sorbitol, sodium carboxymethylcellulose), and then the steamed vermicelli after extrusion is pickled with a sour a...
