Abstract

The invention discloses a processing method for compressed fruit and vegetable food and belongs to the technical field of food processing. The processing method for the compressed fruit and the vegetable food solves the problems that existing compressed food contains lots of calorie, and nutrient loss is severe. The processing method comprises the steps of 1, selecting materials, wherein fresh fruits or vegetables meeting hygienic standards are selected as raw materials and washed clean; 2, drying the raw materials, wherein the raw materials are placed in a drying bin to be dried, and raw material semi-finished products are obtained; 3, lowering the temperature, wherein the raw material semi-finished products are placed in a warehouse to be cooled; 4, conducting smashing, wherein the raw material semi-finished products recovered to room temperature are smashed and screened with a sieve with 60-80 meshes, and raw material powder is obtained; 5, compressing the raw material powder, wherein the raw material powder is compressed to sheet-shaped or block-shaped products, and the products are packaged and stored. Products produced through the method are smaller in size, higher in energy density, longer in shelf life, short in production period, low in cost and convenient to produce in a mass mode.

Description

technical field [0001] The invention relates to a processing method of compressed food, in particular to a processing method of compressed fruit and vegetable food, and belongs to the technical field of food processing. Background technique [0002] With the development of modern science and technology, people pay more and more attention to nutrition and health. In recent years, food technology has emphasized returning to nature, but there are still many problems in the current food, such as high additive content and serious damage to the nutritional content of food. Compressed dry food is a better carrier of food. It is small in size and easy to carry, which meets the needs of the fast-paced human life. However, the compressed food produced by the prior art has high calories and insufficient dietary fiber, water-soluble vitamins and minerals. Meet human requirements for a healthy diet. Contents of the invention [0003] The purpose of the present invention is to provide...
