The influence of two autochthonous lactobacilli strains with probiotic potential (Lactobacillus mucosae CNPC007 and Lactobacillus plantarum CNPC020) in comparison to a commercially available probiotic strain (Lactobacillus rhamnosus LR32) in non-fermented dairy desserts added with ingredients (syrup and hydroethanolic extract) derived from jabuticaba (Myrciaria cauliflora) peels was investigated. L. mucosae showed the best survivability and stability of the studied lactobacilli after processing and during storage, respectively, and also remarkably influenced the texture and sensory features of desserts in comparison to the other strains; L. plantarum achieved viability comparable with the commercial probiotic, above 6 log cfu/g up to the 21st day of the products refrigerated storage. The hydroethanolic extract and syrup from the jabuticaba peel contributed to the phenolic content of the dairy desserts (around 30 mg GAE/100 g) that showed to be able to scavenge DPPH radicals (around 300 g dessert/g DPPH). The different lactobacilli strains did not significantly influence the antioxidant capacity parameters of the desserts (p > 0.05), although the desserts' color was not stable during storage and tended to reduce the acceptability scores of the three trials. Non-fermented dairy desserts with jabuticaba peel ingredients showed to be good sources of phenolic compounds with an antioxidant capacity, offering suitable conditions for the viability maintenance of the autochthonous lactobacilli cultures.
研究了两种具有益生菌潜力的本土乳杆菌菌株(黏膜乳杆菌 CNPC007 和植物乳杆菌 CNPC020)与一种市售益生菌菌株(鼠李糖乳杆菌 LR32)在添加了源自嘉宝果(Myrciaria cauliflora)果皮的成分(糖浆和水醇提取物)的未发酵乳制品甜点中的影响。黏膜乳杆菌在加工和储存过程中表现出最好的存活率和稳定性,与其他菌株相比,还显著影响了甜点的质地和感官特征;植物乳杆菌的存活率与商业益生菌相当,在冷藏储存的第 21 天,活菌数达到 6 个对数 cfu/g 以上。嘉宝果果皮的水醇提取物和糖浆增加了乳制品甜点的酚类含量(约 30mg GAE/100g),并具有清除 DPPH 自由基的能力(约 300g 甜点/g DPPH)。不同的乳杆菌菌株对甜点的抗氧化能力参数没有显著影响(p>0.05),尽管在储存过程中甜点的颜色不稳定,且有降低三次试验接受度评分的趋势。含有嘉宝果果皮成分的未发酵乳制品甜点是酚类化合物和抗氧化能力的良好来源,为本土乳杆菌培养物的存活提供了适宜的条件。
