Xeem tsim
Cov ntaub ntawv xeem: mis nyuj tshiab,xylo-oligosaccharides, Lactobacillus bulgaricus (Lb), Streptococcus thermophilus (St).
Kev ua kom muaj zog: Ua kom Lactobacillus bulgaricus thiab Streptococcus thermophilus hauv skim mis peb zaug kom txog thaum lawv qhov kev ua haujlwm ruaj khov (kev txiav txim los ntawm kev tshuaj xyuas microscopic thiab curdled mis nyuj), tom qab ntawd muab cia rau hauv lub tub yees rau siv tom qab. Txoj kev sim: Npaj 21 qhov sib npaug ntawm cov qauv mis nyuj tshiab thiab faib ua 3 pawg, nrog rau 7 tus qauv hauv txhua pawg. Ntxiv cov concentrations (%, w / v) ntawm 0, 0.5, 0.6, 0.7, 0.8 rau cov qauv hauv txhua pawg. , 0.9 thiab 1.0 xylo-oligosaccharides, thiab sib tov Lb thiab St nyob rau hauv proportions ntawm 2: 1, 1: 1, thiab 1: 2 raws li ua kom pib kab lis kev cai, thiab tom qab ntawd inoculate rau hauv 3 pawg nrog cov nyiaj inoculation ntawm 3%. Ferment ntawm qhov kub thiab txias ntawm 42°C, thiab coj mus kuaj ib ntus los ntsuas tus naj npawb ntawm cov kab mob siv tau, pH tus nqi, acidity thiab lactic acid cov ntsiab lus hauv txhua pawg ntawm cov mis nyuj.
xeem tau
(1) Lb: St = 2: 1, cov nyhuv ntawm xylo-oligosaccharides ntawm kev loj hlob thiab acid zus tau tej cov yogurt fermentation hom
Raws li pom tau los ntawm daim duab 1, 0 mus rau 1.5 h yog lub sijhawm hloov pauv ntawm cov kab mob thiab pib theem pib nkag mus rau theem kev loj hlob ntawm logarithmic. Cov kab mob tsis loj hlob sai, pH tus nqi txo qis, thiab acidity thiab lactic acid nce sai. Thaum xylo-oligosaccharide concentration yog 0.7%, tag nrho cov kab mob Qhov siab tshaj plaws tus nqi yog 1.94×108 CFU / mL (kev tswj hwm yog 1.15×108 CFU / mL), thiab pH, acidity thiab lactic acid cov ntsiab lus zoo ib yam li kev tswj hwm; nruab nrab ntawm 1.5 h thiab 3.5 h, cov kab mob nkag mus rau theem kev loj hlob ntawm logarithmic thiab loj hlob sai. Cov pH poob sai sai, thiab acidity thiab lactic acid cov ntsiab lus tau nce sai. Thaum xylo-oligosaccharide concentration yog 0.7%, qhov siab tshaj plaws tag nrho cov kab mob suav yog 5.65×108 CFU / mL (kev tswj hwm yog 5.41×108 CFU / ml). Cov pH, acidity, thiab lactic acid cov ntsiab lus Lawv yog 5.82, 63 thiab 4.93 raws li, thiab pH, acidity thiab lactic acid cov ntsiab lus ntawm kev tswj yog 6.05, 56 thiab 4.67. Los ntawm 3.5 mus rau 4.5 h, tag nrho cov kab mob suav tau txo qis, pH poob qis, thiab acidity thiab lactic acid cov ntsiab lus nce qeeb.
