بررسی میزان افت ترکیبات تغذیه‌ای در طی تولید ماست تغلیظ شده و پنیر لبنه در سطح صنعتی و به روش سپراتوری

در این تحقیق مشخصات شیمیایی دو نوع محصول اصلی (ماست تغلیظ شده پرچرب و پنیر لبنه کم چرب) و محصولات فرعی مربوطه (آب ماست و آب پنیر اسیدی ) و هم چنین هدر رفت مواد مغذی در طی تولید این دو محصول مورد بررسی قرار گرفته است. میانگین داده‌های سه بچ کاملاً صنعتی بیانگر آن است که مقادیر قابل توجهی از مواد مغذی در آب ماست و آب پنیراسیدی وجود دارد. میانگین درصد ماده خشک، پروتئین، چربی، لاکتوز و خاکستر کل برای آب ماست به ترتیب 6.13، 0.71، 0.22، 3.58 و 0.54 و برای آب پنیر اسیدی به ترتیب 6.56، 0.95، 0.30، 3.64 و 0.58 بدست آمد. هم چنین مقادیر بالایی از کلسیم و فسفر در آب ماست (99 و 60 میلی‌گرم در 100 گرم) و آب پنیر (101 و 69 میلی‌گرم در 100 گرم) مورد اندازه‌گیری قرار گرفت. بررسی میزان افت برای لاکتوز، پروتئین، چربی و خاکستر و مشخصاً برای کلسیم و فسفر بیانگر درصد افت بالا برای تمام مواد مغذی بوده و در تمام موارد برای آب پنیر بیشتر از آب ماست می‌باشد. در بین مواد مغذی بیشترین و کمترین افت به ترتیب متعلق به لاکتوز و چربی می‌باشد. محصولات لبنی تغلیظ شده به روش سپراتوری دارای ارزش تغذیه‌ای بالایی هستند ولی میزان مواد مغذی موجود در محصولات فرعی مرتبط با این محصولات نیز قابل توجه می‌باشد. این امر نیازمند به کارگیری روش‌های نوین و فرمولاسیون‌های جدید در جهت استفاده از این محصولات فرعی در تولید محصولات جدید می‌باشد.

Evaluation of the nutrient losses during the production of concentrated yoghurt and labneh cheese at industrial level and in separating method

Centrifugal force for separating different whey’s from main product is one of the most practical and industrially methods for producing concentrated yoghurt and different cheese. In this research chemical characteristic of two main products (concentrated yoghurt and low fat labneh cheese) and related byproducts (two kind of acid whey’s) were investigated. Result of three industrial batch showed, high amount of nutrient is in acid whey’s. Average of dry matter, protein, fat, lactose and total ash for yoghurt whey respectively were 6.13, 0.71, 0.22, 3.58 and 0.54 and for labneh cheese whey respectively were 6.56, 0.95, 0.30, 3.64 and 0.58. Also, the results of the measurements indicate high amount of Ca and P is in yoghurt whey (99 and 60 mg/100g) and cheese whey (101 and 69 mg/100g). Nutrient losses for all compound (lactose, Fat, protein, ash, Ca and P) were remarkable and these loss for yoghurt whey was lower than cheese whey. Among the all compound highest level of loss was for lactose and lowest level was for fat. Concentrated dairy product have a high nutritional value but there is considerable amount of nutrient in related byproducts. This will need to be using new methods and formulation for producing new products.
