Abstract

The present invention discloses a health and safe preservation technology of tomatoes. The health and safe preservation technology comprises the following steps: I, pretreatment; II, pre-cooling; III,preservation treatment; IV, sterilization; and V, refrigeration. The health and safe preservation technology of the tomatoes is simple in process steps, environmentally protective and safe, can effectively reduce the nutrient loss of the tomatoes, delays occurrence of cold damage symptoms of the post-harvested tomato fruits, inhibits the decay and deterioration of the tomato fruits, and prolongsthe shelf life of the tomatoes.

Description

Technical field [0001] The invention relates to the technical field of food preservation, in particular to a tomato healthy and safe preservation process. Background technique [0002] Tomato, also known as tomato, is a 1-year-old herbaceous plant in the Solanaceae family. As one of the most widely consumed vegetables in the world, tomatoes are rich in nutrients such as vitamins, organic acids, sugars and minerals. Due to the high moisture content of tomato, the fresh tender skin is thin, it is very easy to damage, it is a respiration type fruit, the ripe fruit is easy to be softened, senescence, and disease-causing microorganisms infects and cause quality deterioration and rot during postharvest storage and transportation. Not conducive to storage and transportation. [0003] At present, there are many ways to store tomatoes. The commonly used tomato preservation technologies in China now mainly include cold storage, modified atmosphere preservation, dry preservation, etc., and ...
