    Study Notes

    Fruits & Vegetables - Definitions

    • Vegetables are the edible parts of herbaceous plants.
    • Herbaceous plants have flexible stems with little to no woody part.
    • Vegetables are often grouped by the edible part, like leaves, stems, or roots.

    Fruits - Definitions & Classification

    • Fruits are the mature ovaries of flowering plants.
    • Ovaries contain seeds that develop after fertilization.
    • Fruits' main purpose is to spread plant seeds.
    • Fruit classifications include: Simple, Aggregate, Multiple, and Accessory.

    Parts of a Plant

    • Fruits: Avocado, cucumber, eggplant, okra, pepper, pumpkin, snap beans, squash, tomato
    • Flowers: Artichoke, broccoli, cauliflower
    • Stems & Shoots: Anise (fennel), asparagus, celery, kohlrabi
    • Leaves: Beet greens, bok choy, Brussels sprouts, cabbage, chard, Chinese cabbage, collards, dandelion greens, endive, escarole, kale, lettuce, mustard greens, parsley, romaine spinach, turnip greens, watercress
    • Tubers: Ginger root, potato, sunchoke
    • Roots: Beet, carrot, celeriac, jicama, parsnip, radish, rutabaga, sweet potato, turnip
    • Seeds: Beans, corn, lentils, peas

    Pigments & Nutrients

    • Carotenoids: Fat-soluble pigments (yellow, orange, red, purple) with antioxidant properties. Examples: carotene, lycopene, xanthophyll, lutein, zeaxanthin. Found in carrots, oranges, peaches, pineapples, red peppers, tomatoes, and winter squashes.
    • Chlorophyll: Fat-soluble pigment, slightly soluble in alkaline media, responsible for green color in plants and algae. Essential in photosynthesis.
    • Flavonoids: Water-soluble pigments with antioxidant properties. Some examples: anthocyanin, anthoxanthin, betalains. Found in berries, cauliflower, onions and beet roots.

    Nutrients & Health Benefits

    • Good sources of dietary fiber, potassium, folate, vitamin A, and vitamin C.
    • Commonly low in fat and calories, and cholesterol free.
    • Phytochemicals offer anti-inflammatory, anti-oxidant, and anti-cancer effects.

    Vegetable & Fruit Storage

    • Fruits: Store ripe fruits for a shorter period, unripe in a paper bag. Grapes are best stored unwashed in refrigerator in plastic bag.
    • Vegetables: Store at room temperature or in the refrigerator depending on the type of vegetable. Keep vegetables in refrigerated crisper drawer to preserve moisture and to maintain freshness.

    Browning of Fruits & Vegetables

    • Tannins: Naturally occurring polyphenols; bitter taste and astringent feeling. Common in unripe fruits.
    • Enzymatic browning: Reaction of tannins with PPO enzymes in presence of oxygen.
    • To avoid browning: heat, acid, cold temperatures (inhibits, but doesn't prevent), and antioxidants (ascorbic acid & sulfur compounds).

    Preparation Methods to Preserve Color

    • Blanching: Foods cooked briefly in boiling water, then plunged in ice water. This helps retain color and stops the cooking process.

    Ripening and Storage

    • Climacteric Fruits: Continue ripening after harvest (e.g., apples, avocados, bananas, tomatoes).
    • Non-climacteric Fruits: Best ripen before harvest (e.g., blueberries, cherries, grapes, strawberries).

    Sensitivity to Cold

    • Non-chilling-sensitive commodities: Do not need to be stored in cold temperatures (e.g., Apple, Apricot, Avocado, Banana...).
    • Chilling-sensitive commodities: need specific temperatures (e.g., bananas, melons, sweet potatoes).

    Definitions of Fruit Types

    • Berries: Fleshy fruits without a pit, entire ovary wall in a single flower.
    • Citrus Fruits: Typically sour, with a waxy outer layer. Rich in vitamin C.
    • Fleshy Fruits: Thick, soft, and succulent fruits. Larger in size, sometimes seeds edible along with the flesh e.g. melons and papaya.
    • Pomes: Fruits with a central core surrounded by edible flesh and a tough outer layer. Apples and pears.
    • Stone Fruits (Drupes): Have pulp on the outside and an inedible large, hard stone in the middle, plums, cherries, peaches, and mangoes.

    Acidity in Fruits

    • Acidity is due to organic acid in the vacuole.
    • Acidity decreases as fruits ripen.
    • Volatile and non-volatile acids.
    • Common organic acids: citric, malic, tartaric, oxalic.
