Problems solved by technology

This kind of fruit and vegetable powder often adds more sugar content, which is not conducive to the health of consumers, especially middle-aged and elderly consumers
In addition, complex changes will occur between the various chemical components added to the fruit and vegetable powder during the fermentation process, resulting in interactions between the fruit and vegetable powder and probiotics, which may reduce the activity of probiotics and the functional effects of the fruit and vegetable itself

Embodiment 1

[0026] The present invention provides a kind of preparation method of middle-aged and elderly blueberry probiotic powder, comprising the following steps:

[0027] Step 1, under aseptic condition, dissolve the freeze-dried bacterial powder of Bacillus natto in sterilized physiological saline, and activate it statically at 37°C for 30 minutes;

[0028] Step 2, culture Bacillus natto based on sterilization at 121°C for 20 minutes, then cool to 37°C, inoculate statically activated strains according to 10% of the medium volume, and culture statically in an anaerobic box at 37°C for 12 hours; Centrifuge the good bacterial solution at 4000rpm for 15min to collect the bacterial sludge;

[0029] Step 3, adding 2% glycerin, 15% skimmed milk powder, 2% gelatin, and 12% trehalose to the bacteria slime in sequence, pre-freezing at -80°C for 12 hours, and then freeze-drying to obtain probiotic powder;

[0030] Step 4: Select fresh blueberries to remove rotten and diseased fruits, wash them...

Embodiment 2

[0035] The present invention provides a method for preparing probiotic powder of middle-aged and aged blueberries. The difference from the examples is that the sonic crushing power is 650W, the temperature is 38°C, and the ultrasonic time is 15min. 2; the detection results of active ingredients in the blueberry probiotic powder that the present embodiment obtains are as shown in table 1.

[0036] Table 1 Detection of active ingredients in blueberry probiotic powder

[0037] Example Anthocyanin content Bacillus natto protein sugar content 1 1.2mg / g 0.27g / g 4.42mg / g 5.7％ 2 1.3mg / g 0.26g / g 4.53mg / g 5.9％

Embodiment 3

[0039] The present invention provides a method for preparing probiotic powder of middle-aged and aged blueberries. The difference from Example 1 is that in step 4, only a beater is used for crushing. Detect the dissolved substances in the serum obtained in step 3 of Example 1 and Example 2, as shown in Table 2.

Abstract

The invention provides a preparation method of blueberry probiotic powder for middle aged and elderly people. The preparation method comprises the following steps: dissolving freeze-dried bacillus natto powder in sterilized normal saline in a sterile state, and carrying out static activation; sterilizing a bacillus natto culture medium, inoculating a strain which is subjected to static activationaccording to 10% of the volume of the culture medium, and carrying out anaerobic static culture at 37 DEG C for 12-15 hours; centrifuging the cultured bacterial solution, and collecting bacterial sludge; based on 100% of the bacterial sludge, sequentially adding 2% by mass of glycerol, 15% by mass of skim milk powder, 2% by mass of gelatin and 12% by mass of trehalose into the bacterial sludge, carrying out pre-freezing at -80 DEG C for 12 hours, and then carrying out freeze-drying to obtain probiotic powder; primarily crushing fresh blueberries, then performing ultrasonic crushing, performingfiltering, and collecting clear liquid; sequentially adding xylitol, high fructose syrup and maltodextrin into the blueberry clear liquid, and then performing sterilizing and freeze-drying to obtainblueberry fruit powder; and mixing the probiotic powder and the blueberry fruit powder according to a mass ratio of (0.75-1):1 to obtain the blueberry probiotic powder.

Description

technical field [0001] The invention relates to a probiotic powder, which belongs to the technical field of formulas of health care products, in particular to a middle-aged and elderly blueberry probiotic powder and a preparation method thereof. Background technique [0002] Since Tissey discovered the first strain of beneficial bacteria—Bifidobacteria in 1899, human research on probiotics has never stopped, and the benefits of probiotics on human health have also been increasingly revealed, such as promoting the body Absorption and utilization of nutrients, maintenance of intestinal micro-ecological balance, enhancement of immune function and so on. It has also given birth to a variety of health products added with probiotics, among which probiotic fruit and vegetable powder is the most popular among middle-aged and elderly consumers. However, most of the existing probiotic fruit and vegetable powders are produced by using the probiotic freeze-dried powder to ferment the c...
