Abstract
The application relates to the technical field of microorganisms, in particular to a composite fermentation method of lactobacillus plantarum ZF605 and lactobacillus paracasei ZF616 and application thereof. The compound fermentation method combines the flavor characteristics of the two bacterial metabolites, and butanedione with butter flavor is produced in the fermentation process. The method is applied to the fermentation process of soy sauce, can not only improve the richness of the taste of the soy sauce on the premise of not obviously increasing the difficulty of fermentation operation and production cost, but also reduce salty impact and salty and fragrant feel of the soy sauce while improving the oleic acid feel of the soy sauce, so that salty and sour are not unbalanced, the flavor modification effect is achieved, and the salty and sour are mixed more naturally when the soy sauce is matched with seasonings such as table vinegar.
Description
Technical Field
The application relates to the technical field of microorganisms, in particular to a composite fermentation method of lactobacillus plantarum and lactobacillus paracasei and application thereof.
Background
In recent years, with the acceleration of the life rhythm of the young people in the current generation and the continuous improvement of the taste requirements of food, the development of the pre-made dish industry is accelerated, and simultaneously, new requirements are also provided for the dish flavor. The cold dishes play a role in allaying hunger and stimulating appetite on modern dining tables in summer, and the cooked vegetables or meats are mainly used as the main ingredients, and various seasonings such as soy sauce, aromatic vinegar or apple vinegar, sesame oil and the like are used as the auxiliary ingredients to endow cool and sour flavor. The traditional seasoning mode enables the taste of dishes to be prominent in salty and sour feeling according to the proportion of added soy sauce or the proportion of aromatic vinegar, the whole flavor structure is unbalanced, salty and sour separation is shown, and the taste is transitional and unnatural.
In the aspect of the technology for improving the flavor quality of brewed soy sauce at present, the characteristics of mellow fragrance and thick taste of the soy sauce are mainly presented by improving the content of flavor substances of the soy sauce such as substances of full glutamic acid, amino nitrogen, 4-vinyl guaiacol and the like, the technology mainly aims at using the 'sauce, fresh and fragrant' taste of the soy sauce, and the evaluation standard is mainly a single seasoning mode. According to the preparation method of the soy sauce, as 202211309055.1, cellulase is added in a starter making link, and amylase, glutaminase and other enzyme preparations are added in the process of fermenting soy sauce mash to improve the content of the total nitrogen glutamic acid in the soy sauce. 202211171572.7A soy sauce brewing technology for improving the whole flavor of soy sauce by directionally adding acid flora and aroma-enhancing bacteria, wherein the composite flavor fermentation flora comprises lactobacillus, acetobacter and trichoderma hedgehog, but the addition of the complex microbiota easily reduces the stability of the yeast microbiota, is difficult to predict abnormal aroma production, and is unfavorable for the control and later adjustment of the sensory properties of crude oil.
Along with the enhancement of health consciousness in recent years, the consumption of the food additive is reduced, and the requirements of people on healthy life are met. Therefore, how to improve the taste of soy sauce while meeting the health requirements of people and to make the taste transition of the flavoring juice more natural by matching with vinegar becomes the focus of research.
