Problems solved by technology

[0008] Although the tussah moth has a high food and medicinal value, according to the survey, the edible tussah moth is mainly used in the tussah stocking areas and some cities in the north, and it is less eaten in the south. Stored in frozen mode, the taste of eating is much worse than that of fresh food

Abstract

The present invention relates to a modified atmosphere preservation technology of tussah food. The modified atmosphere preservation technology of the tussah food is characterized by comprising the following steps: material selecting is conducted: fresh tussah larvae, tussah pupae, tussah tender pupae or tussah moths are prepared; packaging is conducted: the selected tussah larvae, tussah pupae, tussah tender pupae or tussah moths are subjected to modified atmosphere preservation packaging and packaging bags should be selected with food-grade packaging bags with at least 3 layers of composite high-gas barriers and filled gas is nitrogen and carbon dioxide gas; and sterilizing is conducted: the packaged tussah larvae, tussah pupae, tussah tender pupae or tussah moths are placed in a counter-pressure high-temperature sterilization pot for the sterilizing, after set sterilizing time is completed, counter-pressure temperature-lowering begins, so that the manufactured tussah larva, tussah pupa, tussah tender pupa or tussah moth food does not break the bags, and the tussah food in the bags can maintain original shape, does not produce water, is free of deformation and good in eating mouthfeel, and can be stored at room temperature for 3 months and cold-stored for 6 months. The manufactured modified atmosphere preserved and packaged tussah food can be eaten once the bags are opened andcan also be used for eating methods of stir-frying, oil-frying, grilling, etc.

Description

technical field [0001] The invention relates to the technical field of food, and relates to a modified atmosphere fresh-keeping production process of tussah silkworm food. Background technique [0002] Tussah is an insect belonging to the genus Tussah of the Lepidoptera Cephalidae family. It belongs to complete metamorphosis insects. One generation passes through four developmental stages: egg, larva, pupa, and adult. Tussah silkworm chrysalis is one of the main products of tussah sericulture. Tussah silkworms are artificially raised in the wild in the oak forest. They feed on the leaves of the tussah tree without pollution. They are a kind of natural insect food and have high edible and medicinal value. my country is the world's largest producer of tussah cocoons, with an annual output of about 70,000 tons of cocoons, accounting for more than 80% of the world's total cocoon production. Among fresh tussah cocoons, tussah chrysalis account for more than 75% of the total weigh...
