Jogurt od devinog mlijeka i melase borovice

In this study, yoghurt was produced from camel (Camelus dramedarius) milk with whey protein isolate (3 % w/v) and fortified with 3 % (w/v) traditional samphire molasses (TSM) (YTSM), 3 % (w/v) TSM+0.1% (w/v) κ-carrageenan (YTSMC) or 3 % (w/v) TSM+0.05 % (w/v) xanthan gum (YTSMX). In yoghurt samples, physical-chemical properties, texture, color and sensory analysis were determined on the 1st, 5th, 10th and 14th days of storage, while total phenolics (TF) levels were determined on the 14th, 24th, 32nd, 48th, 72nd, 120th, 240th and 336th hours of storage. In all samples during storage, hardness and viscosity increased along with the acidity increase, although the increases in YTSM and YTSMC were lower than in YTSMX. In YTSMX, in spite of the increase in acidity after the 1st day, serum separation was very low while viscosity and hardness values were higher compared to the other samples. YTSMX was found to be superior to the other samples in terms of physicochemical, textural, microbiological and sensory properties. Total phenolic contents and L*a*b* levels increased in all samples throughout storage, the highest values of which were in YTSMX. After the 5th day of the storage, Lactobacillus delbrueckii subsp. bulgaricus became the dominant microbial flora. After the 5th day of storage, Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus levels were highest in YTSMX.Jogurt od devinog mlijeka (Camelus dramedarius) proizveden je u 3 varijante: (A) uz dodatak proteina sirutke (3 % w/v) i melase borovice (3 % w/v); (B) uz dodatak proteina sirutke (3 % w/v) i melase borovice (3 % w/v ) + 0,1 % (w/v) κ-karagenana; (C) uz dodatak proteina sirutke (3 % w/v) i melase borovice (3 % w/v ) + 0,05 % (w/v) ksantan gume. Fizikalno-kemijska svojstva, tekstura, boja te senzorska svojstva praćeni su 1., 5., 10. i 14. dana skladištenja. Koncentracija fenola analizirana je nakon 14, 24, 32, 48, 72, 120, 240 i 336 sati skladištenja. U svim uzorcima utvrđeno je povećanje kiselosti, čvrstoće i viskoziteta tijekom skladištenja, ali u jogurtu uz dodatak ksantan gume (C) to povećanje je bilo jače izraženo, te je u tom jogurtu (C) izdvajanje sirutke bilo vrlo slabo izraženo. Također, jogurt C je pokazao bolja fizikalno-kemijska, teksturalna, mikrobiološka i senzorska svojstva u odnosu na druga dva jogurta (A, B). Ukupna koncentracija fenola također se povećavala tijekom skladištenja, a najveće vrijednosti utvrđene su u jogurtu C. Najveća koncentracija Lactobacillus delbrueckii subsp. bulgaricus i Streptococcus thermophilus bakterija nakon 5. dana skladištenja utvrđena je u jogurtu C
