Effect of modified atmospheric packaging on chemical and microbial changes in dietetic rabri during storage

Rabri is a dairy based sweet popular in the Indian subcontinent. The high sugar and fat content impose restrictions on its consumption due to health reasons. Dietetic rabri was prepared by the replacement of sugar with aspartame. Inulin was added to partially replace the milk fat and to improve the consistency of rabri. The rabri samples were packed in the polyethylene bags filled with different gaseous compositions (Air, 50 % CO2:50 % N2 and 100 % N2) and stored at 10 °C. The shelf life was evaluated on the basis of changes in the chemical quality parameters such as HMF, TBA and FFA and microbial content such as total plate count, yeast and molds and coliform counts. The chemical parameters and microbial spoilage increased in all the samples with the progression of storage period. The samples packed with air showed significantly higher chemical deterioration and microbial spoilage as compared to the other two combinations. The samples packed with 100 % N2 were more shelf stable than with air and 50 % CO2:50 % N2 combinations.
