Embodiment 1

[0027] Raw material selection: The whole raw material should be orange-red, smooth and short, fine texture, consistent in size and not too old;

[0028] Cleaning: Clean the qualified raw materials, clean the surface sediment and dirt, and then cut off the head about 5mm and the tail about 2-3cm, so as not to affect the quality of the product;

[0029] Peeling: Peeling removes the bitter substances contained in the skin of the carrot stem. There are many methods of peeling, such as manual method, steam method, chemical method and so on. The steam method is to heat and peel in 0.48Mpa pressure steam for 40-100s or in 0.69Mpa pressure steam for 25-30s; the lye peeling in the chemical method has a sodium hydroxide concentration of 4%-6% and a temperature of 92 -98°C, time 2-3min. After peeling with lye, immediately rinse with flowing water until it is neutral when tested with pH test paper. In industrial production, steam method and lye method are mainly used for peeling;

Abstract

The invention discloses a production process of dehydrated carrot slices, comprising: selecting raw material, washing, skinning, draining, freezing at the low temperature of -35 DEG C for 2 h, lyophilizing, starting to introduce hot steam at 50 DEG C for heating when vacuum degree reaches 80 Pa, and finally packaging to obtain the finished carrot slices. Experiments prove that the dehydrated carrot slices lyophilized by vacuum maintain a maximum degree of color, aroma and taste and nutrients of carrot, are easy to store, have good rehydration characteristic and greatly prolonged shelf life and have increased added value; the dehydrated carrot slices are leisure food suitable for both the young and the old and have a promising market prospect.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable processing, in particular to a production process of dehydrated carrot slices. Background technique [0002] Drying is one of the ways to keep things from spoiling. There are many drying methods, such as drying, boiling, drying, spray drying and vacuum drying. But these drying methods are all carried out at a temperature above 0°C or higher. The products obtained by drying generally shrink in size and harden in texture. Some substances are oxidized, most of some volatile components will be lost, and some heat-sensitive substances, such as proteins and vitamins, will be denatured. Microorganisms will lose biological activity, and dried substances are not easy to dissolve in water, etc. Therefore, compared with before drying, the product after drying has a great difference in properties. [0003] Radishes are rich in carotene, ranking first among common fruits and vegetables. Long-t...
