2. OBJECTIVES
1. prepare ingredients according to a given
recipe, required form, and time frame;
2. thaw frozen ingredients and;
3. wash raw vegetables following standard
procedures.
3. Vegetables are plants or parts of plants like
leaves, fruits, tubers, roots, bulbs, stems,
shoots, and flower used in a dish either raw
or cooked. Vegetables give color, texture and
flavor to our meals. They also give vitamins
and minerals.
4. Vegetables are important part of a healthy diet
because it provide nutrients vital for health and
maintenance of your body. It also provides
health benefits to people to reduce the risk of
some chronic diseases including heart attack
and stroke. Vegetables protect people against
certain types of cancer , reduce obesity and
type two diabetes, lower blood pressures,
reduce the risk of developing kidney stones and
help decrease bone loss.
5. Vegetables are important sources of many
nutrients, including potassium, dietary fiber,
folate (folic acid), vitamin A, and vitamin C.
Diets rich in potassium may help maintain
normal blood pressure. Vegetable sources
of potassium include sweet potatoes, white
potatoes, white beans, tomato products
(paste, sauce, and juice), beet greens,
soybeans, lima beans, spinach, lentils, and
kidney beans.
6. Dietary fiber from vegetables, as part of an
overall healthy diet, helps reduce blood
cholesterol levels and may lower risk of
heart disease. Fiber is important for proper
bowel function. It helps reduce constipation
and diverticulosis. Fiber-containing foods
such as vegetables help provide a feeling of
fullness with fewer calories.
7. Folate (folic acid) helps the body form red
blood cells. Women of childbearing age
who may become pregnant should
consume adequate folate from foods, and
in addition, 400 mcg of synthetic folic acid
from fortified foods or supplements. This
reduces the risk of neural tube defects,
spinal bifida, and anencephaly during fetal
development.
8. Vitamin A keeps eyes and skin healthy and
helps to protect against infections.
Vitamin C helps heal cuts and wounds and
keeps teeth and gums healthy. Vitamin C
aids in iron absorption.
9. Principles of Preparing Vegetables
Avoid overcooking vegetables
When vegetables are overcooked, their
taste, nutritive value and texture suffers. It also
destroys the bright colors which makes them
less appealing to the diners. To preserve the
texture and color of vegetables, they should be
cooked until just tender crisp which means they
can easily bite with a bit of a snap.
10. Principles of Preparing Vegetables
Avoid adding too much fat
Most vegetables are quite low in calories.
Sautéing veggies in lard(fat from animals) can
increase the calories up too high.
11. Principles of Preparing Vegetables
Smaller/young vegetables have often milder
flavor
Smaller/young vegetables are more tender
and more flavorful than mature counterparts.
12. Principles of Preparing Vegetables
Blanching minimizes vitamins loss
Blanching vegetables in hot water for just a
minute takes away much of the raw taste but
minimizes vitamin losses because the process is
quick.
13. Principles of Preparing Vegetables
The addition of spices, herb, onion, garlic,
vinegar or citrus juice can add flavor with
no additional calories.

since fruits and vegetables are good sources of
vitamins and minerals.

yellow fruits and vegetables

26. Color Components
1. Chlorophyll – a fat soluble compound
responsible for the green color of plants.
When combined with acid, it forms
pheophytin which produces an olive-green
color. When combine with alkali, it forms
chlorophyllin's which produces a more
intense green color. The addition of baking
soda when cooking that results to brighter
green color, is an example.
29. Thawing of vegetables is different in thawing
meat and seafoods. To preserve the delicate
cell all of frozen vegetables, different
methods can be used.
36. Basic Knife Cuts
1. Chopping – done with a straight, downward
cutting motion.
2. Chiffonade (shredding) – making very fine
parallel cuts.
3. Dicing – producing cube shapes
4. Diamond (lozenge) – thinly slicing and
cutting into strips of appropriate width
5. Mincing – producing very fine cut usually for
onions and garlic
