preparation example Construction

[0030] A preparation method of probiotic fermented strawberry fruit powder, comprising the following steps:

[0031] Probiotic fermentation: in parts by mass, take 100 parts of sterilized and enzyme-inactivated strawberry pulp, add 100-200 parts of sterile water, 0.001-5 parts of probiotic starter and 1- 10 parts of sugar preparation, mixed evenly, transferred to 37-40°C for fermentation for 60-72 hours, filtered to obtain probiotic fermented strawberry pulp;

[0032] Drying: the fermented strawberry pulp adopts low-temperature vacuum drying method to remove moisture, and obtains probiotic fermented strawberry fruit powder;

[0033] Wherein, the probiotic starter is Bacillus coagulans, or the probiotic starter is a mixed starter composed of at least one of Lactobacillus rhamnosus, Lactobacillus casei and Lactobacillus plantarum and Bacillus coagulans;

[0034] The sugar preparation includes at least one of fructose syrup, glucose powder, dissolved white granulated sugar and h...

Embodiment 1

[0047] Step 1: Prepare Probiotic Seed Solution

[0048] The freeze-dried bacterial powders of Bacillus coagulans, Lactobacillus rhamnosus, Lactobacillus casei, and Lactobacillus plantarum were respectively inoculated into MRS solid medium, and then activated for three generations. Then the activated bacteria were inoculated in the MRS liquid medium to expand the culture, and the bacteria were collected by centrifugation, and finally suspended with 0.85% physiological saline, and prepared as seed liquid for later use.

[0049] Step 2: Prepare the starter

[0050] Prepare skimmed milk emulsion with a concentration of 10% by mass percentage, inoculate probiotic seed liquid with a volume ratio of 5% after sterilization, and cultivate at 37°C. Regularly detect the number of viable bacteria in the fermentation liquid of 4 strains of probiotics, when the number of viable bacteria in each fermentation liquid reaches 10 8 -10 10 When the CFU / mL is reached, the culture is stopped and...

Embodiment 2

[0070] In this example, the first step: preparation of probiotic seed liquid, the second step: preparation of starter and the third step: preparation of powder freeze-dried strains are all the same as in Example 1.

[0071] Step 4: Prepare the compound probiotic starter

[0072] According to the weight of each powder freeze-dried strain, take Bacillus coagulans powder 2g, Lactobacillus plantarum powder 2g, Lactobacillus casei powder 2g and Lactobacillus rhamnosus 2g, mix well and make a compound probiotic starter for fermentation Strawberry puree. The compound probiotic starter is measured for the total number of live bacteria wherein by a stepwise dilution method to ensure that the total number of live bacteria in the composite probiotic starter is greater than or equal to 10 8 pcs / g.

[0073] Step 5: Prepare probiotic fermented strawberry fruit powder

[0074] (1) Preparation of strawberry pulp

[0075] Select 1000g of fresh strawberry fruit with moderate ripeness, good ...

Abstract

The invention discloses a preparation method of probiotic fermented strawberry fruit powder. The preparation method comprises the following steps of performing fermentation with probiotics: taking 100parts of sterilized strawberry pulp after enzyme deactivation, adding 100-200 parts of sterile water, 0.001-5 parts of a probiotic fermenting agent and 1-10 parts of a sugar agent to the taken strawberry pulp, performing uniform mixing to obtain a mixture, transferring the mixture to the condition of the temperature being 37-40 DEG C, performing fermentation for 60-72h, and performing filtrationso as to obtain probiotic fermented strawberry pulp; and performing drying: removing moisture from the fermented strawberry pulp by a low-temperature vacuum drying method so as to obtain the probioticfermented strawberry fruit powder. The invention further discloses the probiotic fermented strawberry fruit powder prepared by the preparation method. The probiotic fermented strawberry fruit powderdisclosed by the invention is not liable to damage, storage and transportation of strawberry products are convenient, the quality guarantee period of the strawberry products is prolonged, and the probiotic fermented strawberry fruit powder also has various efficacy of regulating the intestinal flora of human bodies balanced, alleviating diarrhoea and constipation, promoting digestion, enhancing immunity, preventing cancer, resisting cancer and the like.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of probiotic fermented strawberry fruit powder and the probiotic fermented strawberry fruit powder prepared by the method. Background technique [0002] Strawberry is a herbaceous plant belonging to the family Rosaceae. It has a red heart shape in appearance and contains a special strong fruit aroma. The aroma is rich and sweet. Strawberries are rich in nutrition and contain multiple vitamins (especially VC). The content of VC is 10 times higher than that of apples, watermelons and grapes, and 2 to 3 times higher than that of citrus. It is called "live vitamin pills" in Taiwan. Strawberries also contain organic acids, amino acids, calcium, phosphorus, iron and other minerals and trace elements, especially rich in biologically active substances such as anthocyanins and flavonoids, which have the functions of moistening the lungs and promoting body flui...
