TLE Effects Of Cooking Vegetables And General Rules Of Vegetables In Cookery Flashcards
What are the Effects of cooking vegetables
- Changes in texture
- Water is either lost or absorbed
- Changes in color
- Changes in nutrients
Fibers are often softened or toughened
Changes in texture
What are the changes in texture
A. Cellulose and hemicellulose
B. Addition of acid toughen fibers
C. Addition of alkali like baking soda soften hemicellulose
D. Addition of lime causes firmness or delay softening due to the
reaction of calcium from lime
heating generally softens fibers
A. Cellulose and hemicellulose

What are the effects of Water is either lost or absorbed.
A. Vegetables contain high amount of water, leafy and
succulent vegetables lose water and become limp.
B. Vegetables with significant amount of starch (dried beans,
root crops, tubers) absorb water because of the hygroscopic property of starch.

what are General Rules of Vegetable Cookery
- Don‘t overcook.
- Prepare vegetable as close to service time as possible and in small quantities.
- If the vegetable must be cooked ahead, undercook slightly and chill rapidly. Reheat at service time.
- Never use baking soda with green vegetables.
- Cut vegetables uniformly for even cooking.
- Cook green vegetables and strong – flavored vegetables uncovered.
what are effects of nutrients in Carbohydrate
- moist heat cooking
– gelatinization of starch - dry heat cooking
– dextrinization of starch - carmelization of sugar
what are the Standard Quality of Cooked Vegetables
- Color
- Appearance on plate
- Texture
- Flavor
- Seasonings
- Sauces
- Vegetable combinations
Potatoes, squash, sweet potatoes, and tomatoes should be cooked through with a smooth texture.
- Texture
Bright, natural color
- Color
Cut neatly and uniformly
- Appearance on plate
Cooked to the right degree of doneness: Crisp-tender, not overcooked and mushy.
- Texture
Attractively arranged with appropriate combinations and garnishes
- Appearance on plate
Natural flavor and sweetness
- Flavor
Seasonings should not mask the natural flavors
- Seasonings
Strong – flavored vegetables should be pleasantly mild, with no off flavors or bitterness
- Flavor
Do not use heavily.
- Sauces
Vegetable should not be greasy
- Sauces
Vegetables should be cooked separately for different
cooking times, and then combined
- Vegetable combinations
Combine acid vegetables like tomatoes, to green vegetables just before service to prevent discoloration of
greens.
- Vegetable combinations
