Embodiment Construction

[0019] Choose 2kg of ripe fresh persimmons, clean them, remove the stalks and cores, add 30% of water, and beat the skin and meat in a beater. , separate the fruit juice and pomace, and moderately squeeze the pomace, and combine it with the fruit juice to obtain coarsely filtered juice.

[0020] Aspergillus niger AS5.12 was cultured on a potato dextrose agar slant at 28°C for 5 days, and 1kg of bran was selected as the main material of the medium, and 3% soybean meal medium was added, the initial pH was adjusted to 3.50, and the inoculum size was 10 6 spores / g dry basis, cultivated at 37°C for 80 hours, and made into solid koji.

[0021] Dilute the coarsely filtered persimmon juice with 2 times of distilled water, add solid koji at 5% of the diluted solution, and perform enzymatic hydrolysis treatment at 45° C. for 10 hours. The treated juice is filtered through 8 layers of gauze to obtain juice with clear juice and no sticky feeling.

[0022] Blend the honey and fruit juice...

Abstract

The invention provides a production technique of persimmon mead, which comprises the following steps: using persimmon and honey as raw materials; adding Aspergillus niger to treat persimmon juice; eliminating precipitate and astringency by utilizing tannase and pectinase generated by the Aspergillus niger; adding the honey, and adding Saccharomyces cerevisiae; fermenting the honey persimmon juice; and finally, treating the liquor with cobalt 60-gamma rays to promote the liquor to become mature. Thus, the invention greatly shortens the maturing time of the persimmon mead, thereby producing the fruit mead with unique flavor and abundant nutrients in a short time.
