Q. Which of the following is a method to delay the onset of spoilage on storage?

View solution

Q. The reason why vegetables like green peas and beans are stored in the deep fridge (approximately 0°C) and not ordinary refrigeration is because freshly harvested vegetables themselves release a lot of heat and peas and beans evolve a lot of heat at low temperatures also.

View solution

Q. Which of the following microorganism is popular for spoilage in fruits and vegetables?

View solution

Q. Statement 1: Microorganism responsible for most organism pathogen in humans is thermophile.
Statement 2: Mesophiles have an optimum temperature growth below 10° C and psychrophiles have an optimum temperature growth at around 55° C.

View solution

Q. Which of the following is needed in order to establish a refrigeration requirement?

View solution

Q. The heat load for the storage of fruits and vegetables is calculated by multiplying the specific heat of the food by the number of degrees of the temperature that needs to be lowered divided by the weight of the food.

View solution

Q. Specific heat of food is calculated by the formula Specific heat = 0.008 (percentage water in food) + 0.2.

View solution
