ABSTRACT
Paneer is an acid cum heat coagulated milk product and is widely consumed in the northern part of India. When the food safety officer collecting the paneer sample for chemical analysis, formalin @0.4% is added to remain fit for analytical analysis. In the present study two different packaging pouches i.e. seven layer NYLON/EVOH/70μ polyethylene and 12μPET/70μ polyethylene were used to preserve paneer with or without formalin at 27±1ºC for 120 days. The results revealed that on the addition of formalin @0.4% in paneer samples showed an increase in moisture content (52.88±0.061 to 53.55±0.06%) and acidity (0.62±0.017 to 0.67±0.011% LA), whereas fat percentage decreases (24.02±0.155 to 22.05±0.126%). Tyrosine value, acidity, FFA, peroxide value, of paneer rapidly increased while moisture, fat percentage and pH decreased during storage at 27±1ºC respectively. Paneer sample preserved with formalin in seven layer NYLON/EVOH/70μ polyethylene showed no significant (P>0.05) difference in moisture content (53.55±0.068 to 53.54±0.04%) and fat percentage (22.05±0.126 to 22.04±0.089%) up to 45 days respectively. However, 12μPET/70μ polyethylene pouch showed, no significant (P>0.05) difference in moisture content (53.55±0.068 to 53.53±0.076%) and fat percentage (22.05±0.127 to 21.95±0.080%) upto 30 days respectively. Based on above findings it can be concluded that paneer samples preserved with formalin under vacuum packaging in seven layer NYLON/EVOH/70μ polyethylene pouch at 27±1ºC remained fit for analytical purpose up to 45 days.
