Making method of dried apples

Abstract

The invention relates to a making method of dried apples. A making method of dehydrated apples comprises the following steps of (1) washing apple raw materials; (2) removing peel and cores from the washed apples; (3) cutting the apples obtained in the step (2) into slices, strips or small triangle dices; (4) performing color protection treatment on the apple blocks obtained in the step (3); (5) performing hot air drying on the apple blocks obtained in the step (4); (6) performing microwave drying on the half-dried apple blocks obtained in the step (5); (7) performing vacuum drying on the products obtained in the step (6); and (8) bagging the products obtained in the step (7), inflating nitrogen, and performing sealing so as to obtain the dehydrated apples. According to the making method disclosed by the invention, a combined type drying technology is applied in the process of making the dehydrated apples, so that the negative influences on color, luster and nutrient contents of the apples by long-time heating treatment are effectively avoided, and a dehydrated dried apple product with color and luster close to those of fresh fruits, with the original fragrance of the apples, beingcrisp in mouth feel, and which can be maintained at room temperature for two years or above without deterioration is obtained.

Description

technical field [0001] The invention relates to a method for preparing dried apples.

Problems solved by technology

Hot air drying is the most widely used processing method at present. The advantage is the lowest energy consumption. The disadvantage is that the nutritional components of apples are lost more and the color and shape change greatly; the apple slices made by vacuum freeze drying are better in color and shape, but the production cost is too high. Conducive to energy saving; fried drying is unhealthy and has been gradually abandoned by consumers; microwave drying can easily burn some parts of the product, suitable for drying materials with low moisture content
