Lesson Content/Board Summary

Choice and Storage of Foodstuffs

Meaning of Common Terms

1. Price list: A list showing the prices of goods or services offered by a seller.
2. Food list: A compilation of food items needed, often for a meal, week, or specific event.
3. Bulk buying: Purchasing goods in large quantities, often at a reduced price per unit.
4. Commercial foods: Food products prepared, processed, and sold by businesses or industries.
5. Homemade foods: Food prepared in the home, often using fresh ingredients and traditional methods.
6. Brand name: A name, term, design, symbol, or other feature that identifies one seller’s good or service as distinct from those of other sellers.
7. Net weight: The weight of the contents of a package, excluding the weight of the packaging material itself.
8. Gross weight: The total weight of a product, including its packaging.

Factors Affecting Food Selection

1. Cost: Budget available for purchasing food.
2. Availability: Seasonal availability of certain foods.
3. Nutritional value: The health benefits and essential nutrients provided by the food.
4. Family preferences: Tastes and dietary requirements of family members.
5. Storage facilities: Availability of appropriate storage equipment (e.g., refrigerator, pantry).
6. Quality and freshness: Appearance, smell, texture, and expiry dates.
7. Quantity needed: Amount of food required for the household.
8. Time for preparation: How long it takes to prepare the food.

The Shopping List

A shopping list is a written or mental list of items to be purchased from a store. It helps in planning, saves time, prevents impulse buying, and ensures all necessary items are bought.

Market Survey and Cost Analysis

1. Market Survey: The process of visiting different markets or stores to compare the quality, availability, and prices of various food items before making a purchase.
2. Cost Analysis: Evaluating the cost-effectiveness of different purchasing options, considering factors like unit price, quantity, and potential waste, to get the best value for money.

Bulk Purchasing of Food

This involves buying large quantities of food items. It is often done to save money (due to lower unit prices) and reduce the frequency of shopping trips. However, it requires adequate storage space and proper preservation methods to prevent spoilage.

Storage Equipment

1. Refrigerator: Used for short-term storage of perishable foods at low temperatures (e.g., fresh fruits, vegetables, cooked leftovers).
2. Freezer: Used for long-term storage of perishable foods by freezing them (e.g., meat, fish, frozen vegetables).
3. Pantry/Cupboard: A cool, dry, dark place for storing non-perishable items (e.g., canned goods, dry grains, pasta).
4. Food containers: Airtight containers for storing dry goods and leftovers to protect from pests and moisture.
5. Baskets/Racks: For storing certain vegetables and fruits that do not require refrigeration (e.g., onions, potatoes).

Storage of Perishable Foods

Perishable foods spoil quickly and require careful handling and storage to extend their shelf life. Methods include:

1. Refrigeration: Storing fresh meats, poultry, fish, dairy products, and most fruits and vegetables in the refrigerator.
2. Freezing: Freezing meats, fish, and some vegetables for longer preservation.
3. Washing and drying: Washing fruits and vegetables just before use or drying them thoroughly before refrigeration to prevent mould.
4. Proper packaging: Using airtight containers or wraps to prevent contamination and moisture loss.

Storage of Non-Perishable Foods

Non-perishable foods have a longer shelf life and can be stored at room temperature, typically in a pantry or cupboard. Methods include:

1. Cool, dry, dark place: Storing items like grains, pasta, canned goods, dried beans, and spices in a pantry away from direct sunlight and heat.
2. Airtight containers: Using sealed containers to protect dry goods from moisture, pests, and air.
3. Original packaging: Keeping items in their original sealed packaging until ready for use.
4. First-in, first-out (FIFO): Using older stock before newer stock to ensure freshness.

Teacher Guide for Using This Lesson Plan

Before the lesson, ensure you have charts of storage facilities and actual samples of perishable and non-perishable foods ready for demonstration. Begin by engaging students with questions about their home experiences with food shopping and storage to activate prior knowledge. Clearly explain each term and concept, using relatable examples relevant to the Nigerian context. Guide discussions on factors affecting food selection and the benefits of planning purchases. During the demonstration of storage methods, emphasise hygiene and practical tips. Allow students to practice creating a shopping list. Ensure students copy the Board Summary notes neatly after the main teaching points have been covered and understood. Monitor their note-taking and provide support where needed. Conclude by reinforcing the practical importance of the lesson for their daily lives.
