Problems solved by technology

Dried vetch is a food that is easy to store for a long time. The process of rehydrating dried scallions is relatively simple, and the rehydration rate of dried scallions is also very low, resulting in poor quality of dried scallions after rehydration, and the taste and taste are not good. , and the existing process of rehydration under normal pressure requires higher temperature and consumes more energy

Embodiment Construction

[0009] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0010] A method for vacuum rehydration of dried weed, which comprises the following steps in turn: dry weed, select, remove impurities, soak in cold water for 4 hours, wash, add warm water at 70°C to the spare vacuum tank, and use a water-vegetable ratio of 6:1 Proportionally add dried weeds for processing, adjust the water temperature to 58°C, vacuumize to -1~-1.6 kPa, maintain the vacuum state for 3 hours, open the tank, and rinse with water for 12 hours.

[0011] Cleaning is to use the mixture of fruit and vegetable cleaning agent and alcohol to clean and then rinse with water. The mixing ratio of vegetable cleaning agent and alcohol is 5:1.

[0012] Within 3 hours under the vacuum state, it gradually changed from -1 kPa to -1.6 kPa and th...

Abstract

The invention discloses a vacuum rehydrating method for dried osmunds and relates to the technical field of food processing. The method is characterized in that the method comprising the following successive steps: selecting dried osmunds, removing impurities, soaking in cold water for 3 to 5 hours, cleaning, adding warm water at a temperature of 70 DEG C to a spare vacuum tank, adding the dried osmunds treated for standby use in the vacuum tank according to a water to dried osmunds ratio of 6:1, regulating the water temperature to 58 DEG C, vacuumizing to a pressure magnitude of 1 to 1.6 kPa below zero, maintaining the vacuumized state for 3 hours, opening the vacuum tank, and rinsing with water for 12 hours. The rehydration rate is improved to 6.5 times from 5.8 times offered by a conventional art. Energy can be saved by lowering the soaking temperature. The product quality is improved and the unique crispness and flavor of osmunds are kept.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a vacuum rehydration method for dried welt. Background technique [0002] Dried Weicai is a dried vegetable made by processing Weicai moss. Wei Cai is an annual or biennial herbaceous plant. It breeds in deep mountains and valleys above 1000 meters above sea level, and likes to be cloudy and damp. Its scientific name is Ziqi, commonly known as Dadongtou, cat's claw, and it was called "nest vegetable" or "vetch" in ancient times. It has a long history and is widely eaten among the people. The earliest "Book of Songs Xiaoya Caiwei" in China. Wei Cai is also a unique nutritious food. It not only has the same unique flavor as bracken, but also has the same nutritional value as bracken, containing a lot of vitamins, protein, and sugar. And tannins, carbohydrates, etc. The processed dried weasel is curved, brown or brown, shiny and elastic. Stir-fried shredded pork with ...
