摘要
发酵调味醋一直有"养生饮料"、"保健醋品"等美誉.该研究以药食同源的蒲公英根、叶以及灯笼草为原料,利用乳酸菌发酵,通过总酸含量、沉淀率等指标确定调味醋比例,优化发酵工艺,对发酵液进行调配及稳定性研究,从而研制出口感较佳、营养成分丰富且抗氧化性良好的蒲公英-灯笼草复合调味醋.结果表明,在蒲公英根∶蒲公英叶∶灯笼草汁为5∶2∶0.2的混合比例下,乳酸菌接种量3％、蔗糖添加量8％、柠檬酸添加量0.02％、CMC-Na添加量0.05％、明胶添加量0.15％、琼脂添加量0.05％、35 ℃发酵65 h为最佳工艺条件.在此发酵条件下,各类抗氧化活性物质增长迅速,具有显著的抗氧化性、在保健调味醋及醋饮料领域具有很好的发展前景.
Abstract
Fermented seasoned vinegar has always been known as"healthy drink"and"healthy vinegar product".In this study,with medicine and food homologous dandelion roots,leaves and Clinopodium polycephalum as the raw materials,lactic acid bacteria are used for fermentation,through the indexes such as total acid content and precipitation rate,the proportion of seasoned vinegar is determined,the fermentation process is optimized,the fermentation broth is blended and the stability is studied,therefore,the dandelion-Clinopodium polycephalum compound seasoned vinegar with better taste,rich nutrients and good antioxidant activity is developed.The results show that under the mixing proportion of dandelion roots∶dandelion leaves∶Clinopodium polycephalum juice of 5∶2∶0.2,3％lactic acid bacteria inoculation amount,8％sucrose addition amount,0.02％citric acid addition amount,0.05％CMC-Na addition amount,0.15％gelatin addition amount,0.05％agar addition amount,and fermentation at 35 ℃ for 65 h are the best technological conditions.Under these fermentation conditions,all kinds of antioxidant active substances grow rapidly and have significant antioxidant activity.It has a good development prospect in the fields of health-care seasoned vinegar and vinegar beverage.
