All food undergoes this process; self-decomposition of food is known as

Explanation
Autolysis refers to the natural breakdown of cells and tissues by their own enzymes, leading to the decomposition of food. This process occurs in all food as a result of enzymatic activity, which occurs after the death of an organism or the harvesting of plant material. During autolysis, the enzymes released from the cells break down the proteins, fats, and carbohydrates present in the food, resulting in the release of nutrients and the formation of byproducts. Autolysis is an essential step in the natural decay and decomposition of organic matter.

3 CLASSIFICATIONS of foods according to perishability

Perishable
Semi-Perishable
Non-Perishable
Fresh
Organic

Correct Answer(s)

A. Perishable
A. Semi-Perishable
A. Non-Perishable

Explanation

The correct answer is Perishable, Semi-Perishable, Non-Perishable. This classification system categorizes foods based on their perishability. Perishable foods are those that have a short shelf life and can spoil quickly if not stored properly, such as fresh fruits and vegetables. Semi-perishable foods have a longer shelf life compared to perishable foods but still need to be consumed relatively quickly, such as dairy products. Non-perishable foods have a long shelf life and can be stored for extended periods without spoiling, such as canned goods or dried grains.

Perishable, Semi-Perishable, or Non-Perishable? What category is Tomato?

P
SP
NP
Not known

Correct Answer

A. P

Explanation

Tomatoes are classified as perishable because they have a relatively short shelf life and can spoil quickly if not stored properly. They are highly susceptible to bruising, rotting, and mold growth, which makes them perishable in nature. Therefore, they belong to the category of perishable items.

Perishable, Semi-Perishable, or Non-Perishable? What category is POTATO?

P
SP
NP
Not known

Correct Answer

A. SP

Explanation

Potatoes are classified as semi-perishable because they have a longer shelf life compared to perishable items but still have a limited lifespan. While they can be stored for several weeks or even months under the right conditions, they will eventually spoil and become inedible. This makes them different from non-perishable items, such as canned goods, which can last for years without spoiling. Therefore, the correct category for potatoes is semi-perishable.

Perishable, Semi-Perishable, or Non-Perishable? What category is BEANS?

P
SP
NP
Not known

Correct Answer

A. NP

Explanation

Beans are classified as non-perishable because they have a long shelf life and can be stored for extended periods without spoiling. They do not require refrigeration or special storage conditions to maintain their quality. This makes them suitable for long-term storage and transportation, making them a non-perishable food item.

Perishable, Semi-Perishable, or Non-Perishable? What category is GARLIC?

P
SP
NP
Not known

Correct Answer

A. SP

Explanation

Garlic falls under the category of semi-perishable. This is because garlic has a relatively long shelf life compared to other perishable items, but it can still spoil or deteriorate over time if not stored properly. Garlic can last for several weeks to a few months when stored in a cool and dry place, making it semi-perishable.

4 FACTORS affecting food spoilage

Microbial
Macrobial
Chemical
Physical
Synthetic

Correct Answer(s)

A. Microbial
A. Macrobial
A. Chemical
A. Physical

Explanation

The correct answer is microbial, macrobial, chemical, and physical. These four factors are known to affect food spoilage. Microbial factors refer to the growth of microorganisms such as bacteria, yeast, and mold that can cause food to spoil. Macrobial factors include pests and insects that can contaminate and spoil food. Chemical factors involve the reactions and interactions of different substances in food that can lead to spoilage. Physical factors include temperature, humidity, and packaging, which can impact the shelf life of food. Synthetic factors are not mentioned in the question and therefore not included in the answer.

Write P(Preservative), S(Stabilizers), C(Coloring), F(Flavoring), A(Antioxidant), N(Nutrients).What category is Salt?

Correct Answer(s)
P

Explanation
Salt falls under the category of P (Preservative) because it is commonly used as a preservative to prevent the growth of bacteria and other microorganisms in food. It helps to extend the shelf life of various food products by inhibiting the growth of spoilage-causing organisms.

General Methods of Food Preservatives

Bacteriostatic
Bactericidal
Bacteriology
Biotechnology

Correct Answer(s)

A. Bacteriostatic
A. Bactericidal

Explanation

Bacteriostatic and bactericidal are both general methods of food preservation. Bacteriostatic refers to substances that inhibit the growth of bacteria, while bactericidal refers to substances that kill bacteria. These methods are commonly used in food preservation to prevent the growth of harmful bacteria and extend the shelf life of food products. Bacteriology is the study of bacteria, and biotechnology refers to the use of biological systems and organisms to develop or manufacture products.
