Problems solved by technology

[0003] In the prior art, the vacuum low-temperature frying and puffing technology is mainly used to produce okra chips. The produced okra chips have the advantages of good color, strong aroma, and crisp taste. However, the vacuum low-temperature frying and puffing technology is used. The okra crisps still have shortcomings such as high oil content, which is not conducive to health.
At the same time, due to the rancidity caused by the oil content, it also seriously threatens its shelf life

Abstract

The invention discloses a production method of instant crisp okra chips. The production method is characterized by comprising the following steps: step 1, treatment of raw materials: selecting fresh okra fruits, performing thorough cleaning and removing pedicles; step 2, color protection by blanching: putting the okra treated in the step 1 into boiled water for 10s, and cooling the okras to 2-5 DEG C after color protection by blanching; step 3, freezing: putting the okra soaked and flavored in the step 2 into a refrigerated warehouse with the temperature of -18 to -15 DEG C for performing freezing for 2-4h; and step 4, microwave vacuum freeze drying: taking out the okra subjected to freezing treatment from the refrigerated warehouse, putting the okra into microwave vacuum freeze drying equipment and performing drying to obtain freeze-dried crisp okra chips with the moisture content of 5% and below by mass. Compared with the prior art, the crisp okra chips produced by the production method of the instant crisp okra chips disclosed by the invention have the advantages of integral appearance, smooth surface, crisp mouthfeel, good sensory quality, longer storage life and the like, andavoid the defects of high oil content and the like in a traditional frying process.

Description

technical field [0001] The invention relates to the field of deep processing of okra, in particular to a production method of instant okra chips. Background technique [0002] Okra, also known as kidney-tonifying grass, okra, okra, etc., is an annual herb of the Malvaceae okra family. It is native to the tropical regions of Africa. It was introduced into my country in the 1990s and is now cultivated everywhere. Okra is eaten with tender fruit, which is rich in protein, free amino acids and minerals. The fruit also contains viscous substances composed of pectin and polysaccharides. It is determined that every 100 grams of tender fruit contains 2.5 grams of protein, 0.1 grams of fat, Sugar 2.7 grams, cellulose A660 international units. 10.2 mg of vitamin B, 20.06 mg of vitamin B, 44 mg of vitamin, 81 mg of calcium, 63 mg of phosphorus, and 0.8 mg of iron are ideal high-grade green nutrition and health vegetables in the new century. In recent years, it has become a popular ve...
