Abstract

The present invention provides a quick-freezing technology of fresh broad beans. The quick-freezing technology comprises the following steps: 3% water in the fresh broad beans is firstly removed, then a hot white vinegar solution is used to spray the broad beans wet and then the broad beans are put still for 1 hour; the broad beans are taken out, the taken out broad beans are rinsed clean with clean water, the rinsed broad beans are naturally air-dried and then the air-dried broad beans are preserved for 2-4 hours; the broad beans are taken out and the taken out broad beans are soaked using a soaking solution; after the soaking, the broad beans are put into a pressure container at a pressure of 0.5 MPa, the pressure is kept for 1 hour, then the broad beans are taken out, the taken out broad beans are treated with clean water once, the broad beans are taken out, and the taken out broad beans are treated with hot oil at 60-70 DEG C for once; distilled water is sprayed on surfaces of the broad beans; and the broad beans are sent into a quick-freezing tunnel to be quick-frozen. The method can greatly maintain freshness of the broad beans. The soaking of the white vinegar can lock water of the broad beans and fills internal pores of the broad beans. The soaking solution can enhance a polymerization force of chlorophyll in the broad beans, so that the chlorophyll is not easily frostbitten when being frozen. The hot oil covers surfaces of the broad beans, so that the freezing can play a certain separating role in the broad beans.

Description

Technical field [0001] The invention relates to the field of quick-frozen food, in particular to a quick-freezing process for fresh broad beans. Background technique [0002] Quick-frozen food refers to the food that has undergone a low temperature treatment below -30°C, and quickly passes through the largest ice crystal zone of -1~-11°C within 30 minutes. More than 80% of the water in the food becomes ice crystals with a particle size of less than 100μm, and the core temperature is at -18°C or less, and the temperature fluctuation of the storage environment is required to be controlled within 2°C. Frozen food obtained through this process. Quick-frozen food keeps the original freshness, color and flavor, nutritional content, appearance quality and internal texture of natural food to the maximum extent. With the rapid development of my country’s frozen food processing industry, as well as the fast-paced lifestyle and the improvement of people’s living standards, quick-frozen foo...
