Naqshadaynta tijaabada
Qalabka tijaabada: caano cusub,xylo-oligosaccharides, Lactobacillus bulgaricus (Lb), Streptococcus thermophilus (St).
Dhaqdhaqaaqa cadaadiska: Ku shaqee Lactobacillus bulgaricus iyo Streptococcus thermophilus caanaha dufanka leh saddex jeer ilaa ay hawshooda xasiloon tahay (waxaa lagu xukumay baaritaan microscopic ah iyo caano la karkariyey), ka dibna ku kaydi qaboojiyaha si hadhow loo isticmaalo. Habka tijaabada: Diyaari 21 qiyaasood oo isku mid ah oo muunado caano cusub ah una kala qaybi 3 kooxood, koox kastana 7 muunado. Ku dar uruurinta (%, w/v) ee 0, 0.5, 0.6, 0.7, 0.8 muunadaha koox kasta. . Qashin heerkul joogto ah oo ah 42°C, oo qaado muunado wakhtiyo joogto ah si loo cabbiro tirada bakteeriyada shaqaynaysa, qiimaha pH, aysiidhka iyo waxa ku jira lactic acid ee koox kasta oo caano ah.
natiijooyinka imtixaanka
(1) Lb: St = 2: 1, saamaynta xylo-oligosaccharides ee koritaanka iyo soosaarka aashitada ee noocyada halsano ee yogurt
Sida laga arki karo Jaantuska 1, 0 ilaa 1.5 h waa xilliga la qabsiga cadaadiska iyo marxaladda bilowga ah ee gelitaanka marxaladda koritaanka logarithmic. Cadaadisku si dhakhso ah uma koraan, qiimaha pH ayaa si tartiib ah hoos ugu dhacaya, iyo acidity iyo lactic acid ayaa si degdeg ah u kordhaya. Marka qiyaasta xylo-oligosaccharide tahay 0.7%, wadarta bakteeriyada Qiimaha ugu badan waa 1.94×108 CFU/ml ( xakamaynta waa 1.15×108 CFU / mL), iyo pH, acidity iyo content lactic acid waxay la mid yihiin kantaroolka; inta u dhaxaysa 1.5 h iyo 3.5 h, cadaadisku wuxuu galaa marxaladda koritaanka logarithmic wuxuuna u koraa si degdeg ah. pH ayaa si degdeg ah hoos ugu dhacday, iyo aashitada iyo waxa ku jira lactic acid ayaa si degdeg ah u kordhay. Marka qiyaasta xylo-oligosaccharide ay ahayd 0.7%, wadarta guud ee bakteeriyada waxay ahayd 5.65×108 CFU/ml ( xakamayntu waxay ahayd 5.41×108 CFU/ml). pH, acidity, iyo lactic acid content Waxay ahaayeen 5.82, 63 iyo 4.93 siday u kala horreeyaan, pH, acidity iyo lactic acid content ee xakamaynta waxay ahaayeen 6.05, 56 iyo 4.67. Laga soo bilaabo 3.5 saac ilaa 4.5 saacadood, wadarta tirada bakteeriyada ayaa hoos u dhacday, pH ayaa hoos u dhacday si tartiib ah, iyo waxa aysiidhka iyo lactic acid ka kooban tahay ayaa si tartiib ah u kordhay.
