Lesson Content/Board Summary

Fruits

Definition of Fruits

Fruits are the mature ovaries of flowering plants, typically containing seeds. They are an important part of a healthy diet, providing essential vitamins, minerals, and fiber.

Types of Fruits

Fruits can be broadly classified based on their structure and characteristics. The following are types of fruits:

Fleshy Fruits: These have a fleshy pericarp (fruit wall).
- Berries: Entire pericarp is fleshy or pulpy (e.g., tomato, grape, banana, date).
- Drupes: Fleshy outer part and a hard, stony inner part enclosing the seed (e.g., mango, plum, cherry, olive).
- Pomes: Fleshy part is derived from the receptacle, with the core containing seeds (e.g., apple, pear).
- Citrus Fruits: Characterized by a leathery rind and juicy segmented flesh (e.g., orange, lemon, grapefruit).
Dry Fruits: These have a dry pericarp at maturity.
- Dehiscent Fruits: Split open at maturity to release seeds (e.g., beans, peas, groundnut).
- Indehiscent Fruits: Do not split open at maturity (e.g., maize, rice, sunflower seed).

Nutritive Value of Fruits

Fruits are rich sources of various nutrients essential for human health. The following are key nutritive values of fruits:

Vitamins:
- Vitamin C (Ascorbic Acid): Found in citrus fruits, guava, pineapple. Important for immune function, skin health, and wound healing.
- Vitamin A (Carotene): Found in yellow and orange fruits like mango, papaya. Important for good vision and skin.
Minerals:
- Potassium: Found in bananas, oranges. Important for blood pressure regulation and muscle function.
- Iron: Present in small amounts in some fruits.
Dietary Fiber: Helps in digestion, prevents constipation, and can help manage blood sugar levels.
Water: Fruits have high water content, contributing to hydration.
Antioxidants: Protect body cells from damage.

Factors Affecting Choice of Fruits

When selecting fruits, several factors influence the choice. The following are factors affecting choice of fruits:

Seasonality: Fruits are usually cheaper and fresher when in season.
Cost: Budget constraints can influence the choice of fruits.
Availability: What is locally available in the market.
Freshness and Quality: Ripe, firm, unblemished fruits are preferred.
Personal Preference: Individual taste and liking.
Dietary Needs/Health Conditions: Specific fruits may be chosen based on nutritional requirements or health concerns (e.g., low sugar for diabetics).

Preparation and Serving of Fruits

Proper preparation and serving ensure fruits are safe and appealing to eat. The following are steps for preparation and serving of fruits:

Washing: Always wash fruits thoroughly under running water, even if they are to be peeled.
Peeling: Peel fruits where necessary (e.g., banana, orange, mango).
Cutting: Cut fruits into desired shapes and sizes, removing seeds or cores.
Arranging: Arrange cut fruits attractively on a plate or in a bowl.
Serving: Serve immediately to preserve freshness and nutrient content.

Fruit Drinks and Juice

Fruit Juice: This is the natural liquid extracted from fruits. Fresh fruit juice is made directly from whole fruits with no added sugar or preservatives. It is a good source of vitamins but lacks the fiber of whole fruits.

Fruit Salad and Jam

Fruit Salad: A dish consisting of various kinds of fruit, sometimes served in a liquid, either their own juices or a syrup. It is a refreshing and nutritious dessert or snack.

Fruit Jam: A fruit preserve made from whole fruit or pieces of fruit, sugar, and sometimes pectin. The mixture is cooked until it reaches a thick consistency suitable for spreading.

Practical Fruit Handling

Safe and hygienic handling of fruits is essential to prevent contamination and spoilage. The following are tips for practical fruit handling:

Wash hands thoroughly before handling fruits.
Use clean utensils, cutting boards, and bowls.
Store fruits properly: some require refrigeration, others room temperature.
Avoid cross-contamination by keeping fruits separate from raw meats.
Handle fruits gently to avoid bruising, which can lead to spoilage.
