Problems solved by technology

At present, boiling water, steam, etc. are generally used for heat treatment to kill enzymes. Although heat treatment is effective, it will lead to the degradation of protein, vitamins and other nutrients, and affect the color, aroma, taste and texture of food.
In addition, during the processing of quick-frozen fruits and vegetables, it is usually necessary to use sharp metal knives to cut raw materials, but the cut surfaces of fruits and vegetables are prone to browning after contact with metal, and the metal knives are easy to wear, which reduces production efficiency or cutting quality

Abstract

The invention relates to the technical field of food processing, in particular to a quick-frozen orange peel production technology. The technology comprises the steps of enzyme deactivation treatment of an orange, peeling, selection, mercerization, rinsing, precooking, dehydration, secondary selection, packaging, cooling and quick freezing. With the adoption of the method, the problem of serious active ingredient loss in the storage process of orange peel is effectively solved, the inherent nutrition of the orange peel is reserved to the greatest extent, and processing and utilization in a later stage are facilitated.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a production process for quick-frozen orange peels. Background technique [0002] Most of the oranges are sold as fresh fruit, but no one cares about the processed fruit, which brings great economic losses to the fruit growers, and some fruit growers have to bury the processed fruit on the spot. In years with high yields, orange sales have always been a major problem for fruit farmers. Deep processing and comprehensive utilization of the peel and pulp of navel oranges is the most effective way to increase orange production. [0003] Quick freezing refers to reducing the temperature of food to a certain temperature below its freezing point in a short period of time, so that all or most of the water contained in the food will form reasonable tiny ice crystals with the internal heat of the food. It is a method to minimize the microbial life activities in food and the liquid...
