新型发酵剂对沙棘果酒品质及抗氧化性的影响

Effects of New Starter Cultures on Quality and Antioxidation of Sea-Buckthorn Wine

  • 摘要: 以沙棘果酒的理化性质、总酚含量、总黄酮含量及抗氧化性为指标,探究酵母菌传统发酵(方法Ⅰ)、巴氏葡萄球菌TS-82联合酵母菌发酵(方法Ⅱ)和酵母菌发酵并添加类胡萝卜素降解酶(方法Ⅲ)三种不同酿造方法对沙棘果酒发酵品质及抗氧化性的影响。结果表明:与方法Ⅰ相比,方法Ⅱ和Ⅲ对pH、可溶性固形物、酒精度、还原糖、滴定酸及微生物指标影响不大,且无致病菌检出。应用方法Ⅱ,可显著提高总酚含量(p<0.05),达到9.3 g/L(gallic acid计),且DPPH·的清除能力(86.5%)和铁离子还原能力(88%)也有所提高(p<0.05)。应用方法Ⅲ,沙棘果酒总酚含量为8.7 g/L(gallic acid计),DPPH·的清除能力为84.7%,铁离子还原能力为87.6%,与方法Ⅱ相比,总酚含量和DPPH·清除能力显著降低(p<0.05)。因此巴氏葡萄球菌TS-82联合酵母菌发酵的方式(方法Ⅱ)应用在沙棘果酒酿造中,在改善风味的同时,有利于开发高抗氧化性的保健食品。

     

    Abstract: This study was conducted to analyze the effects of three different brewing methods including traditional yeast fermentation(Ⅰ),Staphylococcus pasteuri(S. Pasteuri)TS-82 combined with yeast(Ⅱ),and yeast fermentation with carotenoid cleavage enzyme(Ⅲ)on the quality and antioxidation of sea-buckthorn wine. The results showed that compared with traditional method Ⅰ,the physicochemical properties including pH,total soluble solid(TSS),alcoholic strength,reducing sugar and titrable acid as well as microorganisms were hardly affected by methods Ⅱ and Ⅲ. Also,pathogenic bacteria were not detected. The contents of total phenolic compounds,achieved 9.3 g/L(gallic acid)were enhanced significantly(p<0.05)by applying the method Ⅱ,compared with the method Ⅰ. The DPPH·scavenging activity(86.5%)and the reducing capacity(88%)increased accordingly(p<0.05). The contents of total phenolic compounds were 8.7 g/L(gallic acid)by applying the method Ⅲ. The DPPH·scavenging activity and the reducing capacity were 84.7% and 87.6% respectively. Compared with the method Ⅱ,the contents of total phenolic compounds and the DPPH·scavenging activity were significantly lower(p<0.05). Therefore,application of Staphylococcus pasteuri(S. Pasteuri)TS-82 combined with yeast(Method Ⅱ)in sea-buckthorn wine is conducive to develop the anti-oxidative health food.
