Abstract:
PURPOSE: Fermented rice gruel containing fruits or vegetables, and a producing method thereof are provided to offer the excellent health functionality derived from the fruits or vegetables to eaters. CONSTITUTION: A producing method of fermented rice gruel containing fruits or vegetables comprises the following steps: dipping rice in water, and dehydrating the rice before crushing; mixing 100 parts of crushed rice by weight with 50-150 parts of water by weight, and steaming the mixture before cooling; mixing the cooled product with strains of the genus aspergillus, and culturing the mixture to obtain malted rice; adding water into the fermented rice to obtain rice fermented liquid; grinding the rice fermented liquid with a blender and a mixer after sterilizing; and mixing the ground rice fermented liquid with fruit or vegetable puree, and gelatinizing the mixture.
Abstract:
Provided is a method of manufacturing glutinous rice flour for fried rice cakes(Gangjeong) through enzyme treatment, which is able to reduce the soaking period for manufacturing the fried rice cakes and the rate of oil absorption as a cause of acidification during storage of the fried rice cakes and produce the fried rice cakes within 3 to 5hr without soaking for 7 to 21 days. The glutinous rice flour for fried rice cakes is prepared by following three methods (i) controlling 20% glutinous rice flour dispersion to a pH of 6.0 at 37deg.C, adding 1 to 25 units of alpha-amylase(per 100g glutinous rice flour), reacting for 120min or 60 to 120min, lowering the pH to 4.0 and centrifuging (ii) putting glutinous rice flour into 0.001M aqueous NaOH solution to obtain 20% glutinous rice flour dispersion, controlling the pH to 10.0 at 50deg.C, adding 20 to 60 units of protease(per 100g glutinous rice flour), reacting for 5 to 180min, lowering the pH to 4.0 and centrifuging or (iii) putting glutinous rice flour into 0.001M aqueous NaOH solution to obtain 20% glutinous rice flour dispersion, controlling the pH to 10.0 to 50deg.C, adding 20 to 60 units of protease(per 100g glutinous rice flour), reacting for 5min, lowering the pH to 4.0, controlling the glutinous rice flour dispersion to a pH of 6.0, additionally adding 25 units of alpha-amylase(per 100g glutinous rice flour), reacting for 60 to 120min, lowering the pH to 4.0 and centrifuging. The 20% glutinous rice flour dispersion is prepared by soaking glutinous rice in water for 2hr, grinding to 20meshes and adding water.
