摘要

牛油菌和链球菌热灌肠酸奶(Cayratia trifolia, L)调味料的优化。作为对大肠杆菌的抗菌研究已经进行。酸奶是由发酵的全奶油奶粉制成的,它添加了菌根和热部培养,以及草甘膦酸盐提取物。发酵过程在很大程度上依赖于所使用的细菌培养。本研究旨在确定草本菌的最佳成分。这项研究是通过将红杉酸酸奶中的细菌L. bulgaricus和S. thermophilus的成分变化来进行的。对lakum酸奶的分析是通过检测酸度、pH值、花青素水平和大肠杆菌抑制性活动进行的。使用MANOVA(多变量分析)进行数据分析。研究表明,酸奶与L. bulgaricus和S. thermophilus 2:1 (v/v)组合在储存中,酸度增加,pH值下降,提供良好的稳定性。酸奶中的花青素水平在储存过程中下降,而plain(不添加拉酸提法)将L. bulgaricus和S. thermophilus 2:1 (v/v)结合起来,具有最高的抑制性大肠杆菌。牛奶芽孢杆菌和链球菌在酸奶中形成热己糖(Cayratia trifolia, L)的优化。在这个研究中,美国对Escherichia大肠杆菌的研究是第一次。酸奶是由由L。诉讼时效已过。研究的目标是确定L. Bulgaricus和S. thermophilus杆菌对E.大肠杆菌的最佳化合物。这项研究是由L. bulgaricus和S. thermophilus细菌培养在lakum水果酸奶中进行的。Lakum水果酸奶是对酸稳定测试、pH、腺苷水平和抑制抑制抑制抑制抑制进行分析的。数据分析正在对MANOVA进行。The results那里那个lakum水果酸奶composition of The L . bulgaricus和S . thermophilus 2:1 (v / v)有一个好稳定和increased acidity和decreased博士anthocyanin in lakum水果酸奶decreased之价值和普通酸奶(没有lakum水果extract) composition of The L . bulgaricus和S . thermophilus 2:1 (v / v)给《最高inhibitory价值的大肠杆菌。

Optimasi Komposisi Lactobacillus bulgaricus dan Streptococcus thermophilus pada Yogurt Terfortifikasi Buah Lakum (Cayratia trifolia (L.) Domin) sebagai Antibakteri terhadap Escherichia coli
Optimasi komposisi Lactobacillus bulgaricus dan Streptococcus thermophilus pada yogurt terfortifikasi buah lakum (Cayratia trifolia (L.) Domin) sebagai antibakteri terhadap Escherichia coli telah dilakukan. Yogurt dibuat dengan memfermentasikan susu bubuk full cream dengan penambahan variasi kultur bakteri L. bulgaricus dan S. thermophilus, serta penambahan ekstrak buah lakum. Proses fermentasi sangat bergantung pada kultur bakteri yang digunakan. Penelitian ini bertujuan untuk mengetahui komposisi optimal bakteri  L. bulgaricus dan S. thermophilus pada yogurt terfortifikasi buah lakum sebagai antibakteri pada E. coli. Penelitian dilakukan dengan cara memvariasikan komposisi bakteri L. bulgaricus dan S. thermophilus pada yogurt buah lakum. Analisis terhadap yogurt buah lakum dilakukan dengan pengujian stabilitas keasaman, pH, kadar antosianin dan aktivitas daya hambat terhadap bakteri E.coli. Analisis data dilakukan dengan menggunakan MANOVA (Multivariate Analysis of Variance). Hasil penelitian menunjukan bahwa yogurt buah lakum dengan kombinasi L. bulgaricus dan S. thermophilus 2:1 (v/v) memberikan stabilitas yang baik selama penyimpanan dengan nilai keasaman yang meningkat dan pH yang turun. Kadar antosianin dalam yogurt selama penyimpanan mengalami penurunan dan yogurt plain (tanpa penambahan ekstrak buah lakum) dengan kombinasi L. bulgaricus dan S. thermophilus 2:1 (v/v) memiliki daya hambat terhadap bakteri E. coli dengan nilai yang paling tinggi. Optimization of composition of Lactobacillus bulgaricus and Streptococcus thermophilus in yoghurt fortified by lakum fruit (Cayratia trifolia (L.) Domin) extract as an antibacterial against Escherichia coli was investigated for the first time in this research. Yoghurt was made by fermenting milk with several compositions of L. bulgaricus and S. thermophilus as starter cultures and also adding lakum fruit extract as an antibacterial against E. coli. The fermentation process was depended on the bacterial culture used. The aim of the research was to determine the optimal composition of L. Bulgaricus and S. thermophilus bacteria in lakum fruit yoghurt as an antibacterial against E. coli. The research was done by making variation of composition of L. bulgaricus and S. thermophilus bacteria culture in lakum fruit yoghurt. Lakum fruit yoghurt was analysed with acidity stability test, pH, anthocyanin level and inhibitory activity against E. coli.

The results showed that lakum fruit yoghurt with composition of L. bulgaricus and S. thermophilus 2:1 (v/v) had a good stability with increased acidity dan decreased pH. The value of anthocyanin in lakum fruit yogurt decreased and plain yoghurt (without lakum fruit extract) with composition of L. bulgaricus and S. thermophilus 2:1 (v/v) gave the highest inhibitory value against E. coli.
