峡江生麦制曲的生产工艺初探 总被引:2,自引:2,他引:0
“峡江老冬酒”是以当年收割的早尖糯米为原料,并用农家自制的酒曲粒和踩制生麦曲为糖化发酵剂酿制而成。其风味来源主要得益于当地得天独厚的自然条件和以江皮、小麦、红泥土为原料踩制成的生麦曲。该文初探了峡江生麦制曲的工艺制造和操作要求,在此基础上提出了传统生麦踩曲中所含微生物种群和生麦曲的特征和作用。 相似文献

Rheological studies of raw and steamed wheat flour suspensions with added ingredients 总被引:1,自引:0,他引:1
The effect of commonly used ingredients such as salt (NaCl) and oil (groundnut oil) or their mixture on the pasting characteristics using a Rapid Visco Analyser (RVA) and the rheological constants of raw and steamed wheat flour has been studied. All the RVA parameters showed greater changes for steamed flour compared to raw flour and also for salt compared to oil. The flour steamed for 15 min exhibited a point of inflection for most of the RVA characteristics. Apparent viscosity and rheological constants showed slight changes at 30% and 33% batter concentrations while much greater changes were observed at a 36% concentration in the presence of the added ingredients. The steamed flour showed slightly lower values of apparent viscosity compared to raw flour in the presence of salt, oil, or their combination, but slightly higher values of rheological constants. However, at a 33% batter concentration, the values showed only marginal changes, which has implications for the product preparations. 相似文献

不同工艺制曲过程中微生物分布与蛋白酶变化研究 总被引:2,自引:0,他引:2
制曲是酱油酿造的关键环节,直接影响酱油最终产品的质量和原料利用率.实验对原池浇淋及低盐固态2种工艺下制曲过程中总好氧菌(TMAB)、总芽孢菌(Bacterial endospores)、乳酸菌(LAB)、肠道菌群(Enterobactericeae)及真菌(Fungi)的分布状态及蛋白酶变化进行了研究.结果表明,2种工艺制曲12h~15h,主要是好氧性细菌、乳酸菌、肠道菌及酵母菌在迅速繁殖,至制曲15h时基本上达到最大值,其中TMAB及LAB数量均大于109cfu/g,乳酸菌是优势菌,并造成曲料pH值下降.米曲霉在制曲15h后迅速繁殖,21h后对细菌及酵母菌表现出抑制效果.不同工艺制曲对蛋白酶影响不显著,细菌对蛋白酶活有一定的贡献. 相似文献

Each year (2001–2005), 300 samples of wheat from fields of known agronomy were analysed for ten trichothecenes by gas chromatography-mass spectrometry (GC/MS) including deoxynivalenol (DON), nivalenol, 3-acetyl-DON, 15-acetyl-DON, fusarenone X, T2 toxin, HT2 toxin, diacetoxyscirpenol, neosolaniol and T-2 triol and zearalenone by high-performance liquid chromatography (HPLC). Of the eleven mycotoxins analysed from 1624 harvest samples of wheat, only eight were detected, and of these only five–deoxynivalenol, 15-acetyl-DON, nivalenol, HT-2 and zearalenone–were detected above 100 µg kg?1. DON was the most frequently detected Fusarium mycotoxin, present above the limit of quantification (10 µg kg?1) in 86% of samples, and was usually present at the highest concentration. The percentage of samples that would have exceeded the recently introduced legal limits varied between 0.4% and 11.3% over the five-year period. There was a good correlation between DON and zearalenone concentrations, although the relative concentration of DON and zearalenone fluctuated between years. Year and region had a significant effect on all mycotoxins analysed. There was no significant difference in the DON concentration of organic and conventional samples. There was also no significant difference in the concentration of zearalenone between organic and conventional samples, however organic samples did have a significantly lower concentration of HT2 and T2. Overall, the risk of UK wheat exceeding the newly introduced legal limits for Fusarium mycotoxins in cereals intended for human consumption is low, but the percentage of samples above these limits will fluctuate between years. 相似文献

以以低值鱼为氮源,麸皮为碳源,用4种霉菌进行单菌和混菌制曲。以成曲的中性蛋白酶、酸性蛋白酶、糖化酶活力、氨基念氮的含量和发酵液的感观评定为指标,筛选出制曲所选用的菌种。结果表明:经过菌种的筛选,选用As3.042:As3.350=3:1,物料配比为7:3。此时获得的中性蛋白酶活力为1971.28U/g(干基),酸性蛋白酶活力为896.92U/g(干基),氨基酸态氮含晕为2.98g/100g,糖化酶活jj为84.05U/g。 相似文献
