蔬菜脆片属于一种脱水食品,全称为蔬菜真空低温脱水脆片,简称为VF。该产品充分保留了蔬菜的营养成分及色泽风味,具有纯天然,低脂肪,低热量的特点,口感脆酥,清新自然,是目前国际上流行的一种时尚休闲食品。
Dried fish chips belong to a kind of dehydrated food, which is called dried fish vacuum low temperature dehydrated chips, or VF for short. The product fully retains the nutritional components, color and flavor of dried fish. It has the characteristics of pure nature, low fat and low calorie. It tastes crisp, fresh and natural. It is a fashionable leisure food in the world.
(一)油和水的沸点降低(油在84℃左右,水在42℃左右);
(二)达到沸点后,水由液态转为气态;而油则不同;
(三)油和水的比重不同,可以在高沸点下将物料中的水分置换出,能在短时间内使水果、蔬菜等物料迅速脱水。
Because the product is processed in a vacuum tank, and the dehydration of fruits and vegetables is carried out at a relatively low temperature, the nutritional components and natural color and flavor of the food are not damaged by high temperature. Therefore, it is quite different from normal temperature fried food in meaning. Its basic principle is to use the three different physical phenomena of oil and water under the condition of decompression
(1) The boiling points of oil and water decrease (about 84 ℃ for oil and 42 ℃ for water);
(2) When the boiling point is reached, water changes from liquid state to gas state, but oil is different;
(3) Due to the different specific gravity of oil and water, the water in the material can be replaced at high boiling point, which can quickly dehydrate fruits, vegetables and other materials in a short time.
