Storing Grains
What temperature range is ideal for storing grains to prevent rancidity?
10c
What happens to potatoes when they are stored in a refrigerator?
The starch changes to simple sugars, causing cold-induced sweetening.
What happens to milk when it is exposed to light?
It breaks down vitamins and oxidizes fats, making it taste "off."
Which type if meat goes bad the fastest: poultry, pork or beef?
Poultry
Why do whole grain flours go rancid more quickly than white flours?
They contain the germ and bran layer, which has oil that can go rancid.
How do you slow down moisture loss in vegetables and fruits?
By keeping them in a restricted space, such as containers or refrigerator drawers.
How can you prevent eggs from absorbing odors from other foods?
By storing them in an airtight container.
What storage method can slow down the rancidity of meat fats?
Wrapping meat well and storing it in the colder part of the refrigerator (the bottom).
What should grains be stored in to keep them fresh as long as possible?
Air tight containers with tight fitting lids.
Why is it not advisable to store bananas in the refrigerator?
They turn brown and do not ripen at low temperatures.
Why is refrigeration important for milk?
Milk is highly perishable and spoils quickly without refrigeration.
Why do minced and chopped meats spoil faster than larger cuts?
They have a greater surface area exposed to air.
What can happen to grains stored in a warm environment?
They can spoil faster due to rancidity of oils and encourage mould growth.
What is the effect of cutting produce on respiration rates?
It increases the rate of respiration.
What is the impact of storing milk in a transparent container?
It increases nutrient degradation due to light exposure.
What happens to the nutritional content of meat when it is frozen?
Some vitamin E is lost, but proteins do not change significantly.
How does moisture affect the quality of grains?
Moisture encourages mould groth and reduces quality.
What nutrient loss occurs when vegetables are soaked in water?
Water soluble vitamins and minerals leach out into the water.
What happens to milk's nutrients during normal refrigeration?
Most nutrients are preserved; however, light can still degrade some vitamins if exposed.
What is the reason beef has a longer shelf life compared to other meats?
It has a higher content of saturated fat, making it more stable against rancidity.
