Question

1. Some of your friends have produced a product with the formulation indicated below. They decide that it would be best to sell it as a frozen product and want you to calculate how much heat will have to be removed to reduce the temperature from 72°C at which it is processed to a final temperature of -18°C. Unfortunately, all they know about their product is that it freezes at -0.9°C. Luckily, you have taken the Food Processing course and can figure this out once you have the formulation. How much heat must be removed from a batch of their product to reach the desired frozen temperature? For purposes of this calculation, express your answer to the nearest kiloJoule.High molecular weight starches (dry) = 37.7 KgSucrose (5% moisture by weight) = 24.3 kg Protein powder (dry) = 5.7 kg Pure mountain spring water =215.3 kg
