Question 9.
‘Proper information about the purchase, storage and preservation of food is essential.’
In the above context discuss :

(a) Storage of milk to maintain its quality. [5]
Answer:
Storage of milk : Milk comes under the category of perishable foods. Perishable foods are those food items requiring refrigeration and special handling. For storage of milk to maintain its quality we should do the following things :

  • Select milk according to quality needed, i.e., Tonned Milk and Full Cream Milk.
  • Check colour and taste of milk. Generally milk has slightly sweet taste, stale milk has sour taste and an unpleasant smell.
  • Boil milk should be kept in a cool place. If there is no refrigerator, boil milk after every 5-6 hours to keep it free from germs.
  • Never mix old milk with fresh milk.
  • Keep away from strong smelling foods, e.g., onions, guava etc. as it easily absorbs the smell.

(b) Use of salt in food preservation. [5]
Answer:
Use of salt in food preservations: Salt is perhaps most well known as a food preservative and flavouring agent. It has been used to preserve food for many thousands of years and is the most common seasoning. The reason why salt is such an effective preservative is that it draws moisture out of food. Dry foods are less likely to spoil as moisture is a key requirement for organisms that want to spoil the food. But salt also plays other, lesser-known roles in the food we eat as an essential nutrient, providing flavour and texture, and enhancing colour. For these reasons, salt is used in food production, which is why the sodium content of processed foods is so high.
Salt has been used as a preservative for ages, and works to preserve food in two ways :

  • Salt dries food: Salt draws water out of food and dehydrates it. All living things require water and cannot grow in the absence of water, including the bacteria which can cause food poisoning. Salt is used to preserve beef jerky by keeping it dry, and it prevents butter from spoiling by drawing water out, leaving just the fat.
  • Salt kills microbes: In very high salt solutions, many microbes will rupture due to the difference in pressure between the outside and inside of the organism. High salt can also be toxic to internal processes of microbes, affecting DNA and enzymes. Solutions high in sugar also have the same effects on microbes, which is why it is used as a preservative of foods such as jams and jellies.

(c) Need for consumer education to make wise purchases. [5]
Answer:
Need for consumer education: Consumer education means to educate the consumers as to what, how much, where, when and how to buy and how to use what they have bought. It develops critical awareness and living skills which are oriented towards building a better future for all. Consumer education assists the buyer in wise selection of goods to meet family requirements.
As we know, today’s market is a complex system because it is flooded with a variety of products that may confuse the buyer as to what they should buy. As they have limited knowledge, everyone can confuse them easily. Therefore, there is a need for consumer education.
An educate consumer can :

  1. develop the ability to decide and choose things intelligently.
  2. always demand safe, reliable and good quality products at a reasonable price.
  3. take suitable action when faced with a problem.
    At times even an experienced consumer find it difficult to select the best option. The right selection provides immense satisfaction. However, while selecting if certain considerations are kept in mind, one can be assured the purchase of right kind of commodity. The consumer education programme should be aimed at developing an awareness about consumer rights and responsibilities consumer choice and product evaluation.

Question 10.
Explain the following:

(a) Steps and precautions involved in the household method of laundering coloured cotton. [5]
Answer:
Steps and precautions involved in the household methods of laundering coloured cotton: Cotton is available in the low-cost range also. Its maintenance is costly, as it has to be repeatedly washed and finished. As we know cotton clothes catch the soil or dirt very easily so such clothes require frequent laundering.
Steps:

  1. Preparation: Preparation is the first step of laundering process. In this we examine the garments for tears, holes, stains or foreign particles.
  2. Steeping: In steeping, firstly sort out white and coloured cotton garments. The white cotton clothes can be kept soaking overnight, if these are very dirty. If less dirty, they can be soaked for an hour.
    For coloured garments, soaking should be avoided. If required, they should be soaked in tap water for not more than 15 minutes to half an hour.
  3. Washing: As we know, cotton clothes are strong fabrics and become more stronger when wet. When these are very much dirty, they should be washed with scrubbing on  board. Friction or rubbing or scrubbing methods clean them quickly.
  4. Rinsing: Cotton clothes should be rinse two or three times in clean, tap water. It is very important.
  5. Starching and Blueing: These two process should always be performed equally at the same time as it saves time. These are carried to clean the clothes, and make them smooth and bright.
  6. Drying: Drying varies depending upon the type of cloth. As shirts and kurtas should be dried on hangers, trousers are hung folded on the clothes line, salwar and pajamas should be spread full width and sarees, bed sheets should be hung after straightening their edges.
  7. Ironing: As we are talking about cotton clothes, these should be ironed when damp. If they become fully dry, sprinkle water on them to moisten to get good results of ironing. For starched clothes, it is preferable to iron them when still damp.

Extra tips for cotton garments :

  • When it comes to bleach, hvoid using more than the recommended amount with cotton, as it can damage the fibers of your favourites. If your garment has had a finish applied to it, then avoid using bleach altogether.
  • Because cotton items tend to wrinkle and shrink easily, they are usually combined with other fibers. Because of this mix, no cotton garment is created equal so check the fabric care instructions on the tags before washing.
  • Cotton is a durable, soft fiber, and most clothes today are made from it. Unfortunately, it does have one serious drawback: It tends to shrink when washed and dried.

(b) Importance of labels on a packed product. [5]
Answer:
Importance of labels on packed products: A label is expected to provide information about the product. It assists consumer in making a wise selection of the commodity.

Following are the information printed on a label:

  • Name of Product

  • Marks Manufacture and Expiry Date
  • Licence Number
  • Maximum Retail Price (MRP)
  • Net weight of the content
  • Brand Name
  • Manufacture’s Name and Address
  • Ingredients
  • Batch Number
  • Warning, if any
  • Direction of use/storage

(c) Fixed Deposit Account and its features. [5]
Answer:
Fixed Deposit Account: Fixed deposits are investment instruments offered by banks and non-banking financial companies, where you can deposit money for a higher rate of interest than savings accounts. We can deposit a lump sum of money in fixed deposits for a specific period, ranging from 7 days to 10 years. Once the money is invested with a reliable financier, it starts earning an interest based on the duration of the deposit. Usually, the defining criteria for FD is that the money cannot be withdrawn before maturity, but you may withdraw them after paying a penalty.
Features of Fixed Deposits :

  • Fixed deposits enable investors to earn higher interest on their surplus funds.
  • You can deposit money in a fixed deposit account only once, but to deposit more money, you need to create another account.
  • Though liquidity in fixed deposits is lesser, you can look for higher rates of interests, which are higher in case of company fixed deposits.
  • Fixed deposits can be easily renewed.
  • Tax is deducted at source, from interest on Fixed Deposits as applicable, as per the Income Tax Act, 1961.
