摘要:
A method for manufacturing grape juice in which muscat aroma is emphasized is disclosed. The method comprises step (a) and step (b), or comprises step (a), step (b) and step (c): (a) obtaining fruit skin or fruit skin-containing fruit juice by crushing and squeezing grape berries; (b) heating a material formed by adding water to the fruit skin obtained in step (a) or the fruit skin-containing fruit juice obtained in step (a), wherein the temperature of the material or the fruit juice is elevated to reach 45°C to 95°C to form a mixture; (c) air-cooling the mixture obtained in step (b) and subsequently adding an enzyme having a glycosidase activity for diglycoside to the mixture. By using grape juice which is manufactured according to this method as a raw material, wine having rich muscat aroma can be manufactured.
摘要:
A method is disclosed for manufacturing fruit liquor in which muscat fragrance is emphasized. The method includes either or both of set of step (a) and step (d) and another set of step (b) and step (c). Step (a) is to obtain fruit juice or fruit juice containing pericarp, by crushing and squeezing the fruit part of grapes. Step (b) is to heat the fruit juice or the fruit juice containing pericarp obtained in step (a) so as to make the article temperature reach 45 to 95 °C. Step (c) is to add enzyme having the glycosidase activity at the article temperature of fruit juice in a range of 10 to 55 °C. Step (d) is to ferment the fruit juice obtained in step (b) or step (c) using a yeast having the β-glucosidase activity. The fruit liquor manufactured by this method has favorable muscat fragrance.
