The heat of dump grain in storage occurs due to .......... content and growth of moulds.

  1. High moisture

  2. Low moisture

  3. Biotic

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Heating of stored grains results due to the high moisture content in the grains. The grains heat up the water content present in the grain due to thier pre existing temperature which attracts more moisture leading to the growth of microbes in the grains or germinate the seeds thus destroying the yield. 

So, the correct option is 'High moisture'.

How temperature causes damage to a food material?

  1. It affects the growth of casual organisms

  2. Alters the enzyme action

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Food can be spoiled when temperatures are not controlled because high temperature give way for the growth of bacteria and excessive heat increases the rate of enzyme reactions. Exposing food to clod temperature also damages the food.

So, the correct option is 'Both A and B '.

Preventive and control measures adopted for the storage of grains include

  1. Strict cleaning

  2. Proper disjoining

  3. Fumigation

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The grains are stored in huge stores and warehouses. These stores and warehouses should be regularly and strictly cleaned, disinfected and kept dry to avoid ants, insects, worms or rodents infestations and keep the grains safe and hygienic for consumption at any time. There should be proper space or be disjoining between the grain sacks for fumigation and regular inspection of the grains The grains are stored in mass scale in huge chambers called silos. the silos have a proper outlet to withdraw the desired quantity of grains.The silos have built-in arrangements for aeration, fumigation, protection from rodents, insects and bird etc. Thus all three options strict cleaning, proper disjoining and fumigation is equally important for the storage of grains.

Therefore, the correct answer is option D.

In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of:

  1. $Cl _2$
  2. $H _2$
  3. $N _2$
  4. $O _2$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of $N _2$ to prevent from being rancid or oxidised. 
Nitrogen is added to the potato chip packet to add strength to the packaging. Normally aluminium cans are used for packaging beverages, these beverages are carbonated drinks and the carbon dioxide present in them provides the internal pressure in the can and thus gives internal strength to the aluminium can. But in non-carbonated drinks, there is no carbon dioxide present and so Nitrogen is added to it to give the required strength to the packing.

  2. Bacterial metabolism inside the dung releases heat.

  3. Undigested material releases heat due to oxidation by air.

  4. Dung is dark and absorbs a lot of heat.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

At the later stages of decomposition of cowdung, mesophilic micro-organisms decompose the dung, generating heat from exothermic( process which produces heat) processes; such heat generation is associated with the well known phenomenon of the elevated temperature of composting.
