炎夏黄酒生产工艺探索

市通地区坛装低档黄酒市场需求量大，厂家遍地开花，竞争激烈，但受季节的限制，各厂家纷纷于6月底被迫停产，9月初才开始生产。由于是边生产、边销售，各厂家宝坛限制，夏季市场常常脱销，又由于黄酒生产属粗放型生产操作，夏季气温都在30～39t之间，故杂菌繁殖旺盛，缸中品温常常超过菌种生长繁殖所需的正常温度，发酵产生的热量难于散发，从而抑制菌种正常生长发酵，促使杂菌生长繁殖加快，精转酸的比例增多，故此炎夏黄酒生产历来被传统工艺视之为生产“禁区”。我厂通过1994年以来的夏季高温连续性生产取得了突破性进展。一、炎夏黄酒…

RICE WINE BREWING WITH SPROUTING RICE,SPROUTING RICE INFECTED WITH ASPERGILLUS ORYZAE AND RICE KOJI

Fermentation tests were performed with sprouting rice, sprouting rice infected with koji mold, i.e. Aspergillus oryzae and rice koji, as saccharifying agent. Characteristics of the various rice wines were compared by gas chromatography and organoleptic testing. The rice wine made with sprouting rice was colorless and had light and refined characteristics in terms of both aroma and taste. The rice wine made with sprouting rice infected by Aspergillus oryzae was rich in isoamyl alcohol, isoamyl acetate and acetaldehyde; it was faintly yellow in color and had rich and mild characteristics. This rice wine had something in common with conventional Japanese sake as compared with the sprouting rice wine, and it might be a transitional intermediate between ancient sprouting rice wine and conventional Japanese sake. In accordance with the traditional method for sake brewing, starchy materials, tap water and sprouting rice as the saccharifying agent were added to the initital mash as first and second additions. The rice wine was somewhat improved by these additions, as assessed by organoleptic testing. The body of the resultant rice wine was fortified with dextrin and its acidic taste was masked by sugar and dextrin.     

EFFECTS OF PROTEOLYTIC ACTIVITY ON THE CHARACTERISTICS OF AROMATIC RED RICE WINE

The quality of rice wine made from uncooked, unpolished aromatic red rice grain was improved by use of a commercial preparation of acid protease from Aspergillus niger during ethanol fermentation. The fermentation rate of the mash which contained the acid protease was much higher than that of mash that did not contain the preparation of acid protease. The rice wine made from uncooked, polished aromatic red rice, which usually had a less acceptable aroma, was improved by use of the preparation of acid protease, and large amounts of isobutyl alcohol, n-propyl alcohol and ethyl acetate were detected in the resultant rice wine. By contrast, the quality of rice wine made from the bran fraction of aromatic red rice was not improved by the preparation of acid protease. The polished rice fraction of aromatic red rice was affected by the acid protease and the aromatic quality of the rice wine was improved. The aromatic characteristics of red rice wine made from cooked, unpolished aromatic red rice grains, which was rather inferior in terms of both aroma and color, were also improved by the addition of the preparation of acid protease during ethanol fermentation. Thus acid protease has beneficial effects on the production of aromatic red rice wine.

EFFECTS OF THE COOKING PROCESS ON THE CHARACTERISTICS OF AROMATIC RED RICE WINE

Fermentation tests were performed with cooked and/or uncooked, polished aromatic red rice (Oryza sativa var. Indica, Tapol) and aromatic red rice bran using compressed baker's yeast and a preparation of glucoamylase produced by Rhizopus, sp. as saccharifying agent. The quality in terms of both aroma and taste of the red rice wine made with uncooked, unpolished aromatic red rice was much higher than that of rice wine made with cooked, unpolished aromatic red rice. However, the bran fraction of aromatic red rice was fairly resistant to the cooking process and this fraction was hardly affected or degraded by the cooking process. Furthermore, the bran fraction improved the quality of rice wine made from mash that contained cooked, polished rice which had a rather lower-quality aroma. In red rice wine brewing, the polished rice fraction of aromatic red rice may suffer from undesirable effects during the cooking process.
