摘要

[目的] 针对鲜豆渣水分过高难以直接发酵的问题,研究干燥辅料类型及混合比例对豆渣发酵参数的影响,筛选适宜的发酵工艺。[方法] 选取木薯酒糟渣、玉米芯粉和水稻秸秆粉作为水分调节辅料,设置3 个混合比例（92∶8、84∶16和76∶24）,并以纯豆渣作为高水分对照组。所有组别均接种1×10⁷ CFU/g的植物乳杆菌,发酵30 天后测定相关指标。[结果] 玉米芯粉和水稻秸秆粉能有效降低物料水分,提高发酵品质;其中玉米芯粉组在84∶16比例下乳酸含量最高,感官品质优良。而在76∶24的高辅料比例下,玉米芯粉组出现局部霉变,提示了物料压实度与水分的临界平衡点。木薯酒糟渣组因高灰分带来的强缓冲性及缺乏水溶性碳水化合物,导致pH值显著高于其他组。[结论] 玉米芯粉按84∶16比例混合是优化豆渣发酵与营养保留的最佳工艺。

Abstract

[Objective] Aiming at the problem that fresh soybean residues are difficult to ferment directly due to excessively high moisture content,this study was conducted to explore the effects of types and mixing ratios of dry auxiliary materials on the fermentation parameters of soybean residues,and to screen out suitable fermentation processes.[Method] Cassava distillers' grains,corn cob powder and rice straw powder were selected as moisture-regulating auxiliary materials.Three mixing ratios （92∶8,84∶16 and 76∶24） were set,with pure soybean residues as the high-moisture control group.All groups were inoculated with Lactobacillus plantarum at 1×10⁷CFU/g,and related indexes were determined after 30 days of fermentation.[Result] Corn cob powder and rice straw powder could effectively reduce the moisture content of materials and improve fermentation quality.Among them,the corn cob powder group had the highest lactic acid content and excellent sensory quality at the mixing ratio of 84:16.However,local mould growth occurred in the corn cob powder group at the high auxiliary material ratio of 76∶24,indicating a critical equilibrium point between material compaction and moisture.Due to the strong buffering capacity caused by high ash content and the lack of water-soluble carbohydrates,the pH value of the cassava distillers' grains group was significantly higher than that of other groups.[Conclusion] Mixing soybean residues with corn cob powder at a ratio of 84∶16 is the optimal process for optimizing soybean residue fermentation and nutrient retention.
