Problems solved by technology

At present, the conventional superfine pulverization generally adopts the two-stage method from coarse pulverization directly to superfine pulverization. Because the particle size range of the raw material at the entrance of the second stage is too large, the average particle size of the powder is large, and the powder production rate is low.

Embodiment

[0024] Embodiment: the production of selenium-enriched deodorized superfine garlic powder

[0025] 30 kilograms of fresh garlic heads (moisture content 70% wet basis), firstly selected, washed in cold water, peeled, sliced ​​2mm thick, using sodium selenite as the selenium source, the selenium concentration in the soaking liquid is 80 micrograms / gram, after soaking Carry out constant temperature rapid selenium enrichment (soaking temperature 30 ℃, immersion time 5 minutes, reach selenium content 0.5-0.6 microgram / gram) according to the solid-liquid ratio of 1: 10 in the liquid, carry out vacuum freeze-drying ( In the sublimation drying stage, the partition heating temperature is 70°C, and the temperature is kept constant for 8 hours. In the analysis drying stage, the temperature is lowered to 45°C and kept for 5 hours. 20-35°C) three-stage crushing method (the first stage of mechanical crushing: the average particle size to 1-2 mm, the second stage of mechanical crushing: the ...

Abstract

The present invention relates to deep agricultural product processing and functional food. The preparation process of selenium-enriched deodorized superfine garlic powder includes the steps of: slicing garlic, constant temperature soaking in selenium solution to reach selenium content of 0.5-0.8 microgram / g, vacuum freeze drying to water content below 2% to reach selenium content of 3.6-5.8 microgram / g, three-stage crushing to average size below 10 micron, and final oxygen eliminating packing. The said process can maintain the active components in garlic, eliminate the bad smell of garlic, and make the garlic powder easy to be absorbed by human body.

Description

technical field [0001] The invention discloses a preparation method of selenium-enriched deodorized ultrafine garlic powder, which belongs to the field of deep processing of agricultural products and relates to functional food processing. technical background [0002] Selenium is an essential trace element for the human body. Maintaining an appropriate amount of selenium throughout the year can protect biofilms, eliminate free radicals, fight cancer, prevent aging, and enhance immune function. Garlic itself has the ability to enrich trace selenium in the soil, but in non-high-selenium areas, the amount of selenium contained in garlic itself is still low (1-100ppb), so in order to achieve a functional effect, artificial enrichment is necessary. selenium. [0003] Most of the selenium enrichment of fruits and vegetables adopts prenatal selenium enrichment method, and there are two main methods: 1) foliar spraying selenium enrichment method, 2) soil selenium enrichment method....
