This invention belongs to the field of
food technology, specifically relating to a fermented tomato cube and its preparation method. The preparation method includes the following steps: (1) Peel and seed fresh tomatoes,
cut them into cubes, sterilize them, and place them in a sterile
fermentation container. First, add *
Lactobacillus casei*, mix evenly, and anaerobic ferment. Then, add *
Lactobacillus rhamnosus*, mix evenly, and continue anaerobic
fermentation. After sterilization, fermented tomato cubes are obtained; (2) Wash and peel onions,
cut them into cubes, and pre-cook them to obtain pre-cooked onion cubes; (3) Mix the fermented tomato cubes, pre-cooked onion cubes, and seasonings evenly, cook at 80-85℃ for 20-25 minutes, and cool to
room temperature to obtain fermented tomato cubes. The preparation method of this invention can ensure the efficient increase of total
phenols in fermented tomato cubes while reducing the degradation of
lycopene, achieving synergistic optimization of the
nutritional quality of fermented tomato cubes, and improving the sensory quality of the final product.
