Method for preparing high-salt dilute soy by adopting immobilized cell fermentation

Abstract

The invention discloses a method for preparing a high-salt dilute soy by adopting immobilized cell fermentation, which comprises the following steps of: 1. preparing a soy by using a traditional high-salt dilute fermentation method and preparing a soy stock solution through fermentation for 60-90 days for standby; 2. fetching four strains of activated torulopsis, zygosaccharomyces rouxii, shengxiangsaite candida and soy tetrads to respectively prepare immobilized cell particles; 3. compounding the prepared immobilized cell particles of the four strains of the torulopsis, the zygosaccharomycesrouxii, the shengxiangsaite candida and the soy tetrads in the step 2 to obtain mixed immobilized cell particles; then inoculating the mixed immobilized cell particles into the high-salt dilute fermentation soy stock solution obtained in the step 1 for fermentation; and 4. after fermentation is finished, separating the maturely fermented high-salt dilute fermentation soy and the mixed immobilizedcell particles to obtain a finished product of the high-salt dilute fermentation soy. The method not only can enhance the taste of the high-salt dilute soy, but also shortens the period of soy fermentation and overcomes the defects of long fermentation period, low equipment utilization ratio and higher production cost of the high-salt dilute fermentation method.

Description

technical field [0001] The invention relates to a method for preparing high-salt dilute soy sauce, in particular to a method for preparing high-salt dilute soy sauce by fermenting immobilized cells. Background technique [0002] Soy sauce is a condiment with a long history. At present, domestic soy sauce brewing methods mainly include high-salt dilute fermentation method and low-salt solid-state fermentation method. The low-salt solid-state fermentation method has a short fermentation period, but the product flavor is far inferior to the high-salt dilute state fermentation method. The high-salt dilute state brewing method uses soybeans and flour as the main ingredients, is fermented by microorganisms such as Aspergillus oryzae to make koji, and is brewed by using the fermentation method of high-salt dilute state natural exposure to dew. The fermentation process of the high-salt dilute state fermentation process mainly has two stages of biochemical changes: the first stage i...
