For control of insects and mites in grains, fumigation is done. What factor does the toxicity of fumigation depend on?

Statement 1: Grains are identifiable by their unique volatile organic compounds.Statement 2: Wheat that survives in Britain might not survive in the USA.

Aerobic respiration leads to loss of moisture, rise in carbon-di-oxide and increase of temperature of grain.

In aerobic respiration, hexose decomposes to carbon-di-oxide + Ethyl alcohol + Energy.

Which of the following factor affects the moisture content in a grain bulk?

With the increase in temperature, the amount of relative moisture in the atmosphere decreases.

Statement 1: Heat from external sources penetrates into the grain bulk at a very slow rate.Statement 2: Heat generated by microbes affects grain to a larger extent than the daily temperature fluctuations.

The physical property that influences the deterioration of grain is _____

Statement 1: - amylase increases in the harvested grain which turns wet.Statement 2: Damaged starch has _____ - amylase.

When the protein content is reduced, the moisture content is harder to control.

Statement 1: Packaging material test is followed by formed container test.Statement 2: Compression, impact and vibration and drop tests and standard/offset methods are some of the test for _____

Which of the following is an important criteria for the packaging of a food material?

Shell thickness is directly proportional to the effect of storage of eggs.

Statement 1: Meat is more perishable than fish.Statement 2: At low temperatures, sometimes, the inside of the egg shell might solidify and expansion of the shell might lead to causing of the shell to crack.

Statistics show that -1 deg C is the best temperature to store eggs. With respect to that result, the room temperature can be brought down to a lower value when needed for better results of storage.
