Abstract

Instrumental colour and texture and sensory quality changes in blast-frozen and cryo-frozen ripe jackfruit bulbs packed in A 2 1/2 cans and stored at - 18oC were studied. At the end of 6 months of storage, Instron (W.B. Shear) measurement showed a reduction of toughness from an initial value of 1.62 kg/cm2 to 1.42 kg/cm2 in the case of cryo-frozen bulbs and to 1.29 kg/cm2 in the case of blast-frozen samples. Similarly, the colour retention was better in cryo-frozen product. During sensory evaluation, cryo-frozen bulbs were rated at par till 6 months and later superior to blast-frozen bulbs.
