Background
Tomatoes, i.e. tomatoes, are an annual or perennial herbaceous plant that is rich in nutrients: in recent years, with the improvement of the technological level and the cultivation technology, the annual yield of tomatoes is increased year by year, but if the tomatoes are mainly eaten by fresh foods, the problems of poor storage property, short shelf life, difficult transportation and the like are faced. At present, tomato products in the market mainly comprise tomato sauce, tomato juice, tomato beverage and the like, are mainly concentrated on primary tomato products, and have low nutritional value and single taste. However, the existing tomato products still have the following problems:
1. the existing processing technology mostly peels off the tomato peel manually, and the peeled tomato peel contains more lycopene, crude protein, cellulose and the like, so that the tomato raw material is not completely utilized, the waste degree of the tomato raw material is high, byproducts of agricultural and sideline products are added, and the tomato peel processing technology is not beneficial to environmental protection.
2. Lycopene is unstable when being exposed to light, heat and oxygen, the existing processing technology is not enough, lycopene is easy to generate degradation reaction in the processing process of tomato products and in high-temperature and aerobic environments, so that the content of lycopene in the final product is not high, the existing technology cannot achieve the purpose of well protecting lycopene, and the flavor and color stability of the product are poor.
3. In addition, the tomatoes contain some crude proteins and cellulose which are not easy to be digested and absorbed by human bodies, and the existing process cannot well utilize the nutrient substances in the tomatoes, so that the nutrient resource waste is caused. These are all problems that need to be solved.

The whole utilization of tomatoes can be solved through a biological enzymolysis mode, the utilization rate of tomato raw materials by enterprises is improved, and the problems of tomato peel waste and environment-friendly agricultural and sideline product byproducts are solved.
4. The tomatoes contain some crude proteins and cellulose which are not easy to be digested and absorbed by human bodies, and the cellulose in the tomatoes can be decomposed into glucose by the cellulase; the pectin has a large molecular weight and is difficult to be quickly dissolved by digestive juice of a human body, and no matter the pectin is saliva, gastric juice, pancreatic juice or intestinal juice of the human body, the pectin does not contain enzymes which can destroy the structural integrity of the pectin, so the pectin is difficult to be digested by intestines and stomach of the human body, and the pectinase can decompose the pectin into galacturonic acid and methyl galacturonate, thereby being beneficial to the absorption of the human body; the ficin can decompose the crude protein in tomato into amino acids and polypeptides small molecular substances, which are more beneficial for human body digestion and absorption, and the amino acids and polypeptides substances are beneficial for improving the nutritive value and flavor of the product. The enzymolysis can increase the initial water soluble solid in the tomato pulp, so that the proportion of soluble nutrient substances in the tomato pulp is greatly increased, the later fermentation is facilitated, and the tomato pulp has unique flavor, long taste and rich fermentation flavor. After the tomato pulp is subjected to enzymolysis, more monosaccharide, amino acid and other substances are contained, and conditions which are more favorable for fermentation can be provided for zymophyte: most oligosaccharides require hydrolysis to produce monosaccharides before they can be fermented. The bifidobacterium asteroides, the lactobacillus plantarum and the lactobacillus bulgaricus can ferment sugar to generate acid, natural acidity is provided for a tomato fermented product, and a finished product can have good sour and sweet taste without additionally adding an acidity regulator; diacetyl, acetaldehyde and other substances generated in the fermentation process provide unique flavor for the product; the three fermentation strains are anaerobic or facultative anaerobic strains, and lycopene can be protected from being oxidized to the greatest extent in the fermentation process. The extracellular polysaccharide generated in the fermentation process of the bifidobacterium asteroides has strong viscosity and is relatively stable, the tomato fermentation product can form viscous texture, the stability of the tomato fermentation product is improved, and the viscous texture of the tomato fermentation product can be ensured without additionally adding additives such as xanthan gum and the like into the fermented product. The compounding of the three strains is beneficial to producing various acid, aldehyde, ketone, alcohol and ester flavor compounds after the tomato fermentation, and provides unique flavor for the tomato fermentation product.
