Abstract

The study was carried out to find out the effectiveness of biopreservatives and vacuum packaging on the shelf-life of milk solids based khoa. Khoa samples were prepared individually by combinations of Skim milk powder (SMP) with ghee and whey protein concentrates and SMP with cream (50% fat). The control khoa sample was prepared utilizing full cream buffalo milk (6% fat). Natamycin at 10 ppm and nisin at 100 IU/g were added when khoa was still hot (85–90°C). The samples without biopreservatives were packaged in simple and vacuum packaging. It was found that vacuum packaged as well as biopreservatives incorporated samples were organoleptically acceptable up to 5 months of storage at freezing temperature (−18±2°C).

HIGHLIGHTS

Khoa is very parishable item.

Incorporation of biopreservatives as well as vacuum packaging improved the storage life of khoa.
