High pressure pasteurization of Curry (liquid seasoning) to achieve shelf-life of 100 days and more in the cooler (39-41 F)

摘要

The present invention is a method for pasteurization of Curry, a sauce or simmer sauce made with onion, tomato and plethora of spices, mostly used in Indian or other Asian cuisines. CAPS uses 5 things to achieve such long shelf-life—2-step unique cooking process, ingredients mainly spices, HPP (high pressure pasteurization), PET containers and refrigeration. We are not using HPP here for a 2.5-5 log cycle reduction in microorganisms as done by all products now as our cooking process itself brings microbes level to 10. However as evident from the lab reports, HPP does play a role in extending the shelf-life as we compared both pre-HPP and post-HPP samples. Our choice of PET containers (recycle code 1) has a role too on account of its 50 times less OTR than the microwavable PP containers (recycle code 5) used mostly for the restaurant take-outs.
