The invention belongs to the technical field of food with homology of
medicine and food, and particularly relates to a preparation method of rose ferment. The method comprises the steps of separating petals, sieving, protecting color, carrying out
superfine grinding, carrying out
fermentation pretreatment, planting
bacteria for the first time, planting
bacteria for the second time, planting
bacteria for the third time, finely filtering and feeding collagen to obtain rose ferment liquid. According to the method,
probiotic strains which are good for the intestinal tract of a
human body are selected for use, and the
fermentation temperature is strictly controlled, so that the loss of effective components in roses can be effectively reduced, and the activity of the rose ferment is maintained to the utmost extent; the dominant bacteria are implanted for three times, so that the growth of other bacteria can be effectively inhibited, and the product quality is stable;
lactobacillus acidophilus,
lactobacillus thermophilus and
lactobacillus plantarum are selected, have
symbiosis performance and can be planted in the intestinal tract after being fermented in a mixed way; furthermore, the comprehensive activity of ferment products can be better improved. The prepared rose ferment has a certain prevention function for chronic diseases such as
heart disease and
liver disease, and has the effects of soothing the liver and activating the
spleen. After being eaten for a long time, the rose ferment also has the functions of
smoothing the
skin, whitening the
skin and beautifying the face.
