Preparation method of natural additive-free pure apple powder

Abstract

The invention relates to a preparation method of natural additive-free pure apple powder. The preparation method comprises the following steps: soaking clean and fresh apples in water at 50 DEG C before draining; peeling the apples; removing non-edible parts, such as fruit bases and fruit cores; then, cutting the apples into apple slices with the thickness of 4-8mm; placing the apple slices into aboiling jacketed pan to blanch; placing the blanched apple slices in a vacuum can for vacuum solidification and impregnation by using sweat water as an impregnating solution; transferring the solution to a vacuum drying oven to obtain apple crisps; grinding and screening the apple crisps; and packaging apple powder. The invention improves the dry-method process, introduces vacuum impregnating andvacuum drying treatment working procedures, overcomes the defects of nutrient content loss, original color and luster loss, damaged apple flavor, poor condensation, additive addition, granular sensation absence, and the like brought by a traditional preparation method of apple powder, improves the product quality and decreases the production cost.

Description

technical field [0001] The invention belongs to the technical field of solid beverage processing, and in particular relates to a method for preparing green, healthy and additive-free natural pure apple powder. Background technique [0002] Apples are sweet and sour, fragrant and colorful, and rich in nutrition. Traditional Chinese medicine believes that apples are cool in nature, sweet in taste, and non-toxic; , Yixin Qi, prevent food accumulation, and eliminate mouth poison" are its specialties; it also has the effect of neutralizing excess gastric acid and promoting kidney secretion. Therefore, apples have high therapeutic and health effects. [0003] At present, the production method of apple powder mostly adopts dry method or wet method. The dry process is mainly to dry and dehydrate the raw materials with hot air first, and then crush them. The produced apple powder product has serious loss of nutrients and flavor damage, poor rehydration, and the product loses its o...

Problems solved by technology

The dry process is mainly to dry and dehydrate the raw materials with hot air first, and then crush them. The produced apple powder product has serious loss of nutrients and flavor damage, poor rehydration, and the product loses its original attractive color, which has a great impact on the sensory effect of the product. big impact

The wet process is mainly to homogenize the raw materials before spray drying. Although it can solve some problems of the dry process to a certain extent, it still has the following problems, such as: the particle size of the fruit powder after spray drying is small ( less than 200 mesh), it is easy to agglomerate in water, and its sedimentation and dispersibility are very poor. After being further made into a drink, it does not have a chewy taste of fruit particles; in addition, in order to prevent sticking to the wall during spray drying, a certain proportion of drying agent should be added Additives, etc., affect the pure natural taste of the product
