Study Notes
Legumes: Overview
- Legumes are part of the Fabaceae family, the third largest flowering plant family.
- Flowers are 5-petaled and bilaterally symmetrical (butterfly-shaped).
- Fruits are pods containing one row of seeds.
- Pods release seeds when ripe (dehiscent).
- Seeds contain two food-storing cotyledons (dicots).
Composition of Legume Seeds
- Seed coat (testa)
- Micropyle
- Two cotyledons
- Embryo
- Epicotyl
- Radicle
Peanuts
- Originated in South America.
- Introduced to Europe and Africa via trade.
- Grown in light sandy soils.
- Growing cycle is about 5 months.
- Fruits develop underground.
- Different varieties (e.g., runner, Virginia, Spanish, Valencia) have different uses (e.g., roasted, peanut butter, confectionery).
Importance of Legumes
- Inexpensive source of protein, vitamins, minerals, and complex carbohydrates.
- Low in fat and sodium; No cholesterol; Low glycemic index.
- Source of prebiotics that help gut flora.
- Legumes can be considered vegetables or proteins (e.g., green peas, beans).
Preparing Dried Legumes (Pulses)
- Dried beans and soybeans can contain toxins.
- Soak legumes overnight before cooking to reduce toxins.
- Rinse thoroughly and place in a cooking pot with 3 times the volume of cold water.
- Bring to a boil, then simmer until tender.
- Do not boil vigorously.
- Check for doneness; cooked beans should be soft and creamy.
Legumes in Agriculture
- Often used in crop rotation to enrich soil.
- Tolerant of most soil types.
- Self-pollinating.
- Part of the "three sisters" agricultural practice
Soybeans
- Oil content: 13-25%.
- High protein content (30-50%).
- Grow best in warm, temperate, moderate rainfall areas.
- Important crop in China for over 3000 years.
- Immature soybeans are called edamame (cannot be eaten raw).
- Used in soy milk, tofu, and other products.
Soybean Nutritional Highlights
- Rich in protein.
- Good source of various vitamins and minerals.
- Rich in fiber.
Soybean Applications
- Animal feed
- Food products (e.g., breads, pasta, Japanese sticky rice pastes, Vietnamese pancakes)
- Thickening sauces
