Method for brewing persimmon brandy

The invention provides a method for brewing persimmon brandy. The method comprises the following steps: (1) picking ripe persimmon fruits of 'Fuping Sharp Persimmons', naturally airing and freezing the persimmon fruits, then crushing to remove stones and calyxes, measuring sugar, then putting into a fermentation tank, and adding 80-90g / t of potassium metabisulfite; (2) adding 30-50g / t of pectase and 10-30g / t of cellulase, and adjusting the pH value of persimmon juice to be 4.0; and (3) adding high-activity yeasts, stirring fully and uniformly, dissolving by using a persimmon juice-water mixed solution which is 10 times of the weight of the yeast in the tank, placing for 30 minutes to ensure that the temperature difference between the yeast and the persimmon juice in the tank is less than or equal to 10 DEG C, pouring into the fermentation tank, stirring uniformly, fermenting for 8-12 days at 18-20 DEG C, and appropriately adding cane sugar according to the condition of raw materials and alcohol degree in the fermentation process. According to the method, the high-quality raw material of 'Fuping Sharp Persimmons' with local features is adopted and is subjected to air-drying and freezing to obtain persimmon clear juice for fermentation, water is not added, and the raw material liquid is clarified and transparent and is easy to filter; the residual fermentation partial normal juice is utilized, and a Methode Charantaise is adopted for treatment and ageing, thereby obtaining the persimmon brandy which has mellow aroma and a plump wine body.

Preparation method of canned yellow peach in syrup

The invention discloses a preparation method of canned yellow peach in syrup. The preparation method comprises the following steps: performing mixed-enzyme immersion, enzymolysis and covered moistening on the yellow peaches so as to soften the skin of the yellow peaches as well as prevent the yellow peaches from aging, oxidative de-colorization and browning. According to the preparation method, no peeling process is required in the processing cycle, so that the product yield is increased while the original nutrients, color and appearance of the yellow peaches are preserved to the maximum. Cane juice, tea polyphenols and the like are added in the immersion solution, so that the immersion solution is green and natural in ingredients, and has the effects of sterilization and antisepsis; thus, the special mellow fragrance of the yellow peach is preserved. The canned yellow peach in syrup prepared according to the preparation method solves the problem of difficult storage of the yellow peaches. The yellow-peach flesh of the canned yellow peach in syrup is firm in texture but not half-cooked, rough-edged or rotten-soft. The canned yellow peach in syrup is bright and golden in color and luster, elastic, low in fiber content, appropriate in hardness and good in taste.
