Embodiment 1

[0029] A kind of preparation technology of wheat seedling whole powder, the steps are as follows:

[0030] (1) Pretreatment: choose wheat seedlings with a length of 20 cm as raw materials; cut them off from the ground about 3 cm with a shearing machine, immerse them in clear water for washing, and select impurities and yellow leaves, then spray and clean them, and set them aside;

[0031] (2) Color protection: immerse the pretreated wheat seedlings in 70°C water containing 0.3wt% sodium bicarbonate for 8 minutes to remove grassy smell and inactivate oxidase activity, put them in 25°C clear water for 3 minutes after color protection ;

[0032] (3) dehydration: put the blanched wheat shoots into a centrifuge for dehydration;

[0033] (4) Heat pump drying: put the dehydrated wheat seedlings into the drying room, and dry them at 50°C-60°C for 5 hours, and use the eight-stage drying method in Table 1. After drying, the moisture content of the wheat seedlings is not higher than 7 ...

Embodiment 2

[0043] A kind of preparation technology of wheat seedling whole powder, the steps are as follows:

[0044] (1) Pretreatment: choose wheat seedlings with a length of 25 cm as raw materials, cut them off from the ground about 3 cm with a shearing machine, immerse them in clear water for washing, and select impurities and yellow leaves, then spray them for cleaning, and set them aside;

[0045](2) Color protection: immerse the pretreated wheat seedlings in 75°C water with a baking soda concentration of 0.5wt% for 5 minutes to remove grassy smell and inactivate oxidase activity, and then put them into 25°C clear water for 2 minutes;

[0046] (3) dehydration: put the blanched wheat shoots into a centrifuge for dehydration;

[0047] (4) Heat pump drying: put the dehydrated wheat seedlings into the drying room, and dry them for 7 hours in the range of 50°C-60°C, and use the eight-stage drying in Table 2. After drying, the moisture content of the wheat seedlings is not higher than 5 ...

Embodiment 3

[0055] A kind of preparation technology of wheat seedling whole powder, the steps are as follows:

[0056] (1) Pretreatment: choose wheat seedlings with a length of 30 cm as raw materials, cut them off from the ground about 3 cm with a shearing machine, immerse them in clear water for washing, and select impurities and yellow leaves, then spray them for cleaning, and set them aside;

[0057] (2) Color protection: immerse the pretreated wheat seedlings in 80°C water with a mass concentration of 0.8% baking soda for 3 minutes to remove grassy smell and inactivate oxidase activity, and then put them in 25°C clear water for 1 minute;

[0058] (3) dehydration: put the blanched wheat shoots into a centrifuge for dehydration;

[0059] (4) Heat pump drying: put the dehydrated wheat seedlings into a drying room, and dry them at 50°C-60°C for 8 hours, and use the eight-stage drying method in Table 3. After drying, the moisture content of the wheat seedlings is not higher than 4 %:

Abstract

The invention belongs to the technical field of food processing, and particularly relates to a technology for preparing wheat seedling whole flour through combination of heat pump drying and low-temperature superfine comminution. The technology comprises the following steps of sequentially performing pretreatment on wheat seedlings, performing color protection, performing dehydration, performing heat pump drying to prepare coarse flour, performing superfine comminution, and performing microwave sterilization to obtain the wheat seedling whole flour. According to the technology disclosed by the invention, the color, the flavor and the nutrition of the wheat seedlings are protected, temperature control and energy consumption problems in the processing course are solved, the operation sequences are simple, the processing time is short, and the energy consumption is low. The obtained wheat seedling whole flour product has favorable color, favorable flavor, favorable dispersibility and favorable stability, the original nutrients, the original flavor, the original color and the original mouth feel of wheat seedling flour are furthest reserved, and the wheat seedling whole flour is wheat seedling flour whole in nutrients and capable of being fully utilized.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a process for preparing wheat seedling whole powder by combining heat pump drying and low-temperature ultramicro. Background technique [0002] Wheat is an important food crop in my country, especially winter wheat, whose annual output has exceeded 100 million tons. Most of the tillers in winter wheat are ineffective tillers before winter and early spring. Wheat seedlings are the tender stems and leaves of the grass wheat, so the available wheat seedling resources are very abundant. Wheat seedlings are rich in chlorophyll, dietary fiber, beneficial enzymes (SOD) and other nutrients, which can improve the acid-base balance of the human body, expel toxins from the body, clean the blood, and improve immunity. Seventy percent of the solids in wheat seedlings are natural chlorophyll. Chlorophyll can be quickly converted into heme in the human body, and it has sig...
