بررسي خواص عملكردي و توليد ماست فراسودمند با استفاده از كلاژن پوست ماهي سنگسر

Investigation of functional properties and production of ultrasound yoghurt using collagen Gangsar fish skin

هدف از تحقيق حاضر بررسي خواص عملكردي ماست فراسودمند با استفاده از كلاژن پوست ماهي سنگسر بود. نتايج نشان داد كه كمترين قدرت كاهندگي متعلق به نمونه كلاژن طبيعي (2/0 %) و بالاترين ميزان آن در نمونه كلاژن هيدروليز (5 %) بود .(P<0.05) كمترين فعاليت آنتي اكسيداني متعلق به نمونه هاي كلاژن طبيعي (2/0 %) و كلاژن طبيعي (1 %) بود. بالاترين فعاليت آنتي اكسيداني در نمونه كلاژن هيدروليز (5 %) ملاحظه شد (P<0.05). بالاترين حلاليت متعلق به نمونه كلاژن هيدروليز (4pH=) و پائين ترين حلاليت متعلق به نمونه كلاژن هيدروليز (10pH=) بود (P<0.05). نتايج آزمون هاي نمونه هاي ماست نشان داد كه در روز يكم، pH تيمارهاي 2 (محتوي 1% كلاژن طبيعي) و 3 (محتوي (5/1% كلاژن هيدروليز) به طور معني داري پائين تر از ديگر تيمارها بود .(P<0.05) فعاليت آنتي اكسيداني نمونه 4 (محتوي 50% كلاژن + 50% كپسول) بالاترين مقدار را دار بود(P<0.05). همچنين بالاترين سينرزيس متعلق به نمونه شاهد و كمترين ميزان آن در نمونه 4 (محتوي 50% كلاژن + 50% كپسول) ملاحظه شد(P<0.05) در هر دو روز مورد بررسي، اختلاف آماري معني داري در امتياز رنگ، طعم، عطر و بو نمونه ها ملاحظه نشد و تيمار 4 (محتوي 50% كلاژن + 50% كپسول) به عنوان تيمار برتر معرفي شد(P<0.05).

The purpose of this study was to investigate the functional properties and production of ultrasound yoghurt using collagen skin of Sangar. The results of collagen samples showed that the lowest reducind power was observed in normal collagen samples (0.2%) and the highest in collagen hydrolysis (5%) (P<0.05).The least antioxidant activity belonged to normal collagen (0.2%) and normal collagen (1%). The highest antioxidant activity was observed in collagen hydrolysis (5%) (P<0.05). The highest solubility belonged to the collagen hydrolysis sample (pH=4) and the lowest solubility belonged to the collagen hydrolysis sample (pH =10) (P <0.05).The results of tests of yoghurt samples showed that the pH of sample code 5 was significantly higher on day 1 and pH of treatments of code 2 (containing 1% of normal collagen) and 3 (containing 1.5% collagen hydrolysis) There was a significant low level of other treatments (P<0.05). Antioxidant activity of code 4 (containing 50% collagen + 50% capsule) was highest and antioxidant activity The samples were higher than the control sample.On the 14th day, the highest index of Associated Thiobarbituric acid belonged to the control (no collagen) and the least amount belonged to code 5 (containing 100% capsule). On day 1, it was found to be lowest in code 4 (50% collagen content + 50% capsule) and 5 (100% capsule contents). On the 14th day, the highest control group was observed and the lowest was observed in code 4 (containing 50% collagen + 50% capsule) (P<0.05). In both days, a significant difference was found in the color score the taste; odour of the samples were not observed. Only on the first day, the taste and odour of the code 2 sample were significantly lower than other treatments. (P<0.05). Treatment of code 4 (containing 50% collagen + 50% capsule) was introduced as a superior treatment.
