Embodiment 1

[0017] Embodiment 1: the ultramicro treatment of granular yeast

[0018] Source and specifications of granular yeast: Yeast for angel noodles, particle diameter ≤ 500 μm, moisture content ≤ 8%.

[0019] Ultra-fine equipment: "Berry" BM-100S micro-powder machine, provided by Jinan Beili Powder Technology Engineering Co., Ltd.

[0020] Specific steps:

[0021] (1) Set the feed frequency to 1-15Hz; set the discharge frequency to 5-40Hz.

[0022] (2) Automatic feeding according to the selected frequency.

[0023] (3) The yeast cells are squeezed and impacted by the movement of the grinding medium in the pulverizer, and the particles are continuously crushed from large to small. During the crushing process, the large particles are first subjected to force and crushed first.

[0024] (4) After crushing, the particles are discharged according to the selected frequency. Feeding, crushing and discharging are carried out continuously.

[0025] (5) The ultra-fine material directly e...

Embodiment 2

[0027] Embodiment 2: the ultrafine treatment of powdery yeast

[0028] Source and specifications of powdered yeast: Angel nutritional yeast powder, see Table 1 for particle size distribution.

[0029] Ultra-fine equipment: "Berry" BM-100S micro-powder machine, provided by Jinan Beili Powder Technology Engineering Co., Ltd.

[0030] Specific steps:

[0031] (1) The feed frequency is set to 3.4Hz, and the discharge frequency is set to 20Hz.

[0032] (2) Other steps are the same as in Example 1.

[0033] The cell wall breaking rate of the ultrafine edible nutritional yeast powder produced in this example is 80%, and the particle diameter is ≤10 μm. Protein is 48%, moisture is 4%, ash is 5.6%.

[0034] The particle size distribution of the yeast powder before ultramicronization is shown in Table 1, and the particle size distribution diagram and microscopic image are shown in Figure 2 and Figure 3, respectively.

[0035] After micronization, the particle size distribution of t...

Embodiment 3

[0041] Embodiment 3: edible zinc-enriched yeast superfine treatment

[0042] In this embodiment, Angel zinc-rich yeast (produced by Hubei Yichang Angel Yeast Co., Ltd.) with a zinc content of 5000 mg / kg is subjected to ultrafine treatment, and the specific method is the same as that in Example 2.

[0043] According to the following animal experiments, the bioavailability of zinc-enriched yeast ultrafine was determined.

[0044] (1) Take 39 male Wistar rats. The body weight is 40-60 grams. Randomly divided into 13 groups according to body weight, fed with zinc-deficient feed, and after the appearance of the model, the metabolic experiment was carried out. The zinc source was ultrafine zinc-enriched yeast. The intragastric dose was calculated as 4.99mg / kg body weight based on zinc, and the intragastric volume was 1.5ml. / 100g body weight. After gavage, collect urine and feces according to different time periods (0 (before gavage), 0.5, 1, 3, 5, 7, 9, 11, 13, 15, 18, 21, 24h),...

Abstract

The invention involves the production methods of ultrafine nutritional edible yeast powder, including the following steps : (1) to set up the frequency of feed and discharge ; (2) feeding; (3) ultrafine; (4) discharging; (5) packaging, the edible nutritional yeast include leavened dough yeast, Saccharomyces cerevisiae, various edible yeast and yeast which rich in trace elements . The invention also involves the method of production under the Ultra-food nutrition yeast products. The invention use the yeast or yeast particles which under the processing of fermentation, isolation, drying as raw material. According to the invention of the production methods, the cell broken rate is above the 70% of Ultra-food nutritional yeast, its particle diameter less than 150 mum. It can greatly enhance the bioavailability nutritional components within Yeast.

Description

technical field [0001] The present invention relates to a production method of superfine edible nutritional yeast powder, more specifically, relates to a method for breaking the cell wall of edible nutritional yeast by using a superfine pulverizer so that the cell wall breaking rate is ≥ 70%, and the particle diameter is ≤ 150 μm. The edible nutritional yeast includes pasta yeast, saccharomyces cerevisiae, various edible yeasts and various trace element-rich yeasts. The invention also relates to the products produced by this method. Background technique [0002] Yeast is a single-cell microorganism with rich and balanced nutrition. Yeast is rich in protein, minerals, and B vitamins, which can provide people with a variety of comprehensive nutrients, but these nutrients are wrapped by the thick cell wall of yeast . However, there is no effective enzyme in the human body that can digest the yeast cell wall, so the nutrients in the yeast cannot be fully released from the cell...
