[摘 要]【目的】研究直投式酒酒球菌SD-2a发酵剂进行苹果酸-乳酸发酵（MLF）对葡萄酒品质的影响，并与商业MLF发酵剂Viniflora ® Oenos进行比较。【方法】将4 ℃保存的SD-2a和Viniflora ® Oenos发酵剂于室温30min后，均以10 mg/L的接种量直接投入到赤霞珠干红葡萄酒中于20℃进行 MLF，发酵结束后立即加入60 mg/L SO2终止发酵，将发酵后的葡萄酒分别标记为MLF-1和MLF-2，每个处理重复三次。然后采用高效液相色谱法（HPLC）和气质联用法（GC-MS）分别测定CK、MLF-1及MLF-2中的花色苷和挥发性成分，并进行感官分析。【结果】与CK相比，采用SD-2a和Viniflora ® Oenos发酵剂进行MLF都能显著提高葡萄酒的品质。MLF-1发酵时间24天，MLF-2发酵时间20天；CK、MLF-1、MLF-2花色苷含量分别为78.51 mg/L、49.60 mg/L、55.60 mg/L；香气物质含量分别为12.30 mg/L、15.84 mg/L、15.58 mg/L；感官品评得分分别为68.7、74.6、74.9。【结论】直投式酒酒球菌SD-2a发酵剂的MLF性能良好，具有开发商业乳酸菌发酵剂的巨大潜力。 Abstract：【Objective】Study the effect of Direct Vat Set Oenococcus oeni SD-2a starter culture to conduct MLF on the quality of red wine after alcoholic fermentation(AF), and comparing with commercial MLF starter culture (Viniflora ® Oenos). 【Method】Take the SD-2a and Viniflora ® Oenos starter culture from 4℃ to indoor temperature. After 30 min, both of the starter culture were inoculated directly to the Cabernet Sauvignon dry red wine with the inoculum size of 10 mg/L to conduct MLF at 20℃.The wine after MLF were added 60 mg/L SO2 and remarked as MLF-1 and MLF-2 respectively. All three parallel processing. High performance liquid chromatography (HPLC) and Gas Chromatography-Mass Spectrometer(GC-MS) were used to determine anthocyanins and volatile substance content in CK, MLF -1 and MLF -2. Sensory analysis was used to identify the quality of wine.【Result】Comparing with CK, inoculated with Oenococcus oeni SD-2a and Viniflora ® Oenos can finish MLF and improve the quality of wine. MLF-1 finished in 24 days, MLF-2 finished in 20 days; Anthocyanin content of CK, MLF-1 and MLF-2 was 78.51 mg/L, 49.60 mg/L, 55.60 mg/L respectively; Volatile components were 12.30 mg/L, 15.84 mg/L, 15.58 mg/L respectively; Sensory tasting were 68.7, 74.6, 74.9 respectively.【Conclusion】Oenococcus oeni SD-2a showed good fermentation performence, and has potential to be developed as MLF starter culture. |
