8. How to Test Food Components
A. Test for Starch / Carbohydrate
Materials: Food sample, dropper, diluted iodine solution, clean dish.
Procedure: Place a small piece of food on a dish. Add 2–3 drops of diluted iodine solution.
Observation: If the food turns blue-black, starch is present.
Result: Potato, rice, bread and chapati usually show presence of starch.
Important: Sugar is a carbohydrate, but it does not turn blue-black with iodine because iodine detects starch, not all carbohydrates.
B. Test for Fat
Materials: Food sample and paper.
Procedure: Place the food item on paper, wrap it and press gently. Let the paper dry if the food contains water.
Observation: Hold the paper against light. If an oily translucent patch appears, fat is present.
Result: Butter, oil, peanuts and coconut usually show presence of fat.
C. Test for Protein
Materials: Food paste or powder, test tube, water, copper sulfate solution and caustic soda solution.
Procedure: Put half teaspoon of food sample in a test tube. Add 2–3 teaspoons of water and shake well. Add 2 drops of copper sulfate solution. Then add 10 drops of caustic soda solution. Shake and keep undisturbed for a few minutes.
Observation: Violet colour indicates presence of protein.
Result: Gram, pulses, peas, soya bean and peanuts usually show presence of protein.
Safety: Copper sulfate and caustic soda are harmful chemicals. This test should be done only under teacher supervision.
9. Balanced Diet
A balanced diet contains all essential nutrients, roughage and water in the right amount for proper growth and development. Nutritional needs vary according to age, gender, physical activity, health status and lifestyle.
A Good Diet Should Include
Cereals, pulses, fruits, vegetables, milk products, nuts, seeds, water and sufficient roughage.
Avoid Too Much
Potato wafers, candy bars, carbonated drinks, biscuits, noodles and other junk foods.
Why Avoid Junk Food?
It has high sugar and fat but low protein, vitamins, minerals and dietary fibre. Frequent consumption may lead to obesity and health problems.
10. Millets: Nutrition-rich Cereals
Millets are small-sized grains such as jowar, bajra, ragi and sanwa. They are native crops of India and can be grown in different climatic conditions. They are called nutri-cereals because they are rich in vitamins, minerals like iron and calcium, and dietary fibre.
11. Food Miles: From Farm to Plate
The distance travelled by a food item from the place of production to the consumer is called food miles. Reducing food miles helps reduce transport cost and pollution, supports local farmers and keeps food fresh.
12. Textbook Question Answers
1. Pick the odd one out and give reasons.
(i) Jowar, Bajra, Ragi, Chana
Answer: Chana is the odd one out because jowar, bajra and ragi are millets, while chana is a pulse.
(ii) Kidney beans, Green gram, Soya bean, Rice
Answer: Rice is the odd one out because kidney beans, green gram and soya bean are rich sources of protein, while rice is mainly a source of carbohydrate.
2. Discuss traditional versus modern culinary practices in India.
Answer: Traditional culinary practices used tools such as chulha for cooking and sil-batta for grinding. Modern practices use gas stoves, induction cooktops, electric grinders and mixers. Traditional methods required more manual effort and time, while modern methods are faster and easier. These changes happened due to technology, transport and better communication.
3. A teacher says that good food may act as medicine. List two questions Ravi can ask.
Answer:
1. How can fruits and vegetables protect our body from diseases?
2. Which food items should we eat to avoid deficiency diseases like scurvy, anaemia and goitre?
4. Not all delicious foods are necessarily healthy, while not all nutritious foods are always enjoyable. Share your thoughts with examples.
Answer: Many delicious foods like chips, candy bars, noodles and carbonated drinks may taste good but are not healthy because they contain high sugar or fat and very little fibre, vitamins and minerals. On the other hand, nutritious foods like green vegetables, sprouts, millets and pulses may not always be liked by everyone, but they help in growth, energy and protection from diseases. We should learn to enjoy nutritious food by preparing it in tasty but healthy ways.
5. Medu does not eat vegetables but enjoys biscuits, noodles and white bread. He often has stomach ache and constipation. What changes should he make?
Answer: Medu should eat more green leafy vegetables, fresh fruits, whole grains, pulses and nuts because they provide roughage. Roughage helps in smooth passage of stools and prevents constipation. He should reduce biscuits, noodles and white bread because these are low in fibre and may cause digestive problems.
6. Reshma has trouble seeing things in dim light.
(i) Which deficiency disease is she suffering from?
She is suffering from night blindness or poor vision in darkness.
(ii) Which food component may be lacking in her diet?
Vitamin A may be lacking in her diet.
(iii) Suggest four food items.
She should eat carrot, papaya, mango and milk. She may also include other Vitamin A rich foods.
7. Canned fruit juice, fresh fruit juice or fresh fruit — which one would you prefer and why?
Answer: I would prefer fresh fruit because it contains natural nutrients and dietary fibre. Fresh fruit juice may contain nutrients but has less fibre than whole fruit. Canned fruit juice may contain added sugar and preservatives, so it is less healthy.
8. Gourav got a fracture. The doctor gave calcium tablets and later Vitamin D syrup.
(i) Why did the doctor give calcium tablets?
Calcium helps keep bones and teeth healthy. It supports bone repair after fracture.
(ii) Why was Vitamin D given along with calcium?
Vitamin D helps the body absorb calcium properly. Therefore, it supports better healing of bones.
(iii) What question arises in your mind?
A possible question is: Why does the body need Vitamin D to use calcium effectively for bone healing?
9. Sugar is a carbohydrate but does not turn blue-black with iodine. Why?
Answer: Iodine test detects starch, not all carbohydrates. Sugar is a carbohydrate but it is not starch. Therefore, sugar does not turn blue-black with iodine.
10. “All starches are carbohydrates but not all carbohydrates are starches.” Explain with an activity.
Answer: Starch is a type of carbohydrate. Sugar is also a carbohydrate but not starch. To test this, take potato and sugar in separate dishes. Add iodine solution to both. Potato turns blue-black because it contains starch. Sugar does not turn blue-black because it does not contain starch. This proves that all starches are carbohydrates, but all carbohydrates are not starches.
11. Iodine fell on Mishti’s socks and teacher’s saree. Saree turned blue-black but socks did not. Why?
Answer: The teacher’s saree probably contained starch, so iodine turned it blue-black. Mishti’s socks did not contain starch, so there was no colour change.
12. Why are millets healthy? Can eating just millets fulfil all nutritional requirements?
Answer: Millets are healthy because they are rich in vitamins, minerals like iron and calcium, and dietary fibre. They are also called nutri-cereals. However, eating only millets cannot fulfil all nutritional requirements. We need a balanced diet with pulses, fruits, vegetables, milk products, water and roughage.
13. How would you check whether a given solution is iodine solution?
Answer: Take a starch-containing food item such as potato, rice or bread. Add a few drops of the given solution. If the food turns blue-black, the solution may be iodine solution.
