摘要:

杨梅具有较高的营养价值和独特风味。该研究采用植物乳杆菌(Lactobacillus plantarum)对杨梅果浆进行发酵,利用单因素和正交试验探究其最佳发酵工艺,并分析不同发酵程度对杨梅果浆功能性成分、抗氧化能力和风味成分的影响。结果表明,发酵杨梅果浆的最佳工艺为料液比2∶1,初始pH值6.0,海藻糖添加量8%,菌添加量0.8%。在此工艺条件下发酵48 h后,杨梅果浆中的功能性化合物含量显著(P<0.05)升高,总酚、总黄酮和总花色苷含量分别为1.83 μmol·mL-1、5.54 mg·mL-1、31.56 μg·mL-1;抗氧化活性亦得到显著提升,DPPH自由基清除率、ABTS+自由基清除率、羟自由基清除率和总抗氧化能力分别为80.30%、83.95%、65.97%和24.20 mmol·L-1。气相色谱-离子迁移谱(GC-IMS)和主成分分析显示,发酵后的果浆中醇类、醛类和烯烃类物质的相对含量增加,发酵48 h的果浆保留了杨梅的果香、木质香和脂香味,品质最佳。

Abstract:

Chinese bayberry (Myrica rubra) has high nutritional value and unique flavor. In this study, Lactobacillus plantarum was used to ferment bayberry pulp, and the optimal fermentation process was investigated using one-way and orthogonal tests, and the effects of different fermentation levels on the functional components, antioxidant capacity and flavor components of bayberry pulp were analyzed. The results showed that the optimal fermentation process of bayberry pulp was as follows: solid-liquid ratio of 2∶1, initial pH of 6.0, alginate addition amount of 8%, and bacterial addition amount of 0.8%. After 48 h of fermentation under these process conditions, the content of functional compounds in bayberry pulp was significantly (P<0.05) increased, as the contents of total phenols, total flavonoids and total anthocyanosides reached 1.83 μmol·mL-1, 5.54 mg·mL-1 and 31.56 μg·mL-1, respectively; and the antioxidant activity was also significantly enhanced, with the DPPH radical scavenging rate, ABTS+ radicals scavenging rate, hydroxyl radical scavenging rate and total antioxidant capacity being 80.30%, 83.95%, 65.97% and 24.20 mmol·L-1, respectively. Gas chromatography-ion mobility spectrometry (GC-IMS) and principal component analysis showed that the relative contents of alcohols, aldehydes and olefins increased in the fermented bayberry pulp, and the pulp fermented for 48 h retained the fruity, woody and fatty flavors of bayberry with the best quality.
