Abstract
The present investigation ―Standardization of processing technology for instant Kadhi
premix‖ was conducted with objectives to develop instant kadhi premix, and evaluate to the quality and
shelf life of the product during storage. Instant kadhi premix consisted of the kadhi powder, seasoning
and dried vegetables (optional) packed separately. Kadhi was prepared from besan, turmeric and salt
along with curd and buttermilk. It was freeze dried and tray dried; finely ground to form powder and
packed in aluminium and polypropylene pouches. Seasoning was prepared from partially dried
(microwave) and onion and garlic. The developed product was evaluated at 15 days intervals for its
quality and shelf life during the 90 days of storage.
Physico-chemical, the moisture, crude protein, crude fat, crude fibres, ash, carbohydrates and
energy of kadhi powder prepared from curd and buttermilk ranged (4.70 and 4.93%), (8.79 and 9.57%),
(2.90 and 5.10%), (4.90 and 5.87%), (8.46 and 10.15%), (71.10 and 73.94%) and (675-726Kcal).
Moisture, water activity, non-enzymatic browning, acidity, free fatty acids and peroxide value
significantly increased while rehydration ratio was significantly decrease during three months storage
with time. Instant kadhi reconstituted from instant kadhi premix was acceptable during the storage. The
freeze dried kadhi prepared from buttermilk was more acceptable than tray dried kadhi prepared from
curd. Instant kadhi premix packed in aluminium laminated pouches had better storage quality over the
product packed in polypropylene pouches.
The instant kadhi premix took 3 minutes and 30 seconds for reconstitution in boiling water.
The cost of 25 g kadhi powder prepared from curd using freeze drying method was `128.80 instant
premix powder (with seasoning) followed by kadhi prepared from curd using tray drying `31.36, kadhi
from buttermilk using freeze drying `108.61and kadhi prepared from buttermilk using tray drying
`128.80 providing 270 ml of kadhi sufficient for one serving.
