world.

all forms of leafy green
plants, located in the
roots, fruit and grains.

• Starch is a white odorless
tasteless granular or powdery
complex carbohydrate
(C6H10O5)x that is the chief
storage form of carbohydrate in
plants, is an important foodstuff,
and is used also in adhesives and
sizes, in laundering, and in
pharmacy and medicine
• A substance that is found in
certain foods (such as bread, rice,
and potatoes)
1. Cereal Grains
2. Roots &
Tubers
3. Legumes
Corn Potato
Tapioca(Cassava)
Starches are named after
its plant sources:
• Corn Starch from Corn
• Rice Starch from Rice
• Tapioca from Cassava
Arrowroot
Native or Natural Starch refers to the starches
as originally derived from its plant source.
Modified Starches are starches that have been
altered physically or chemically, to modify one or
more of its key chemicals and/or physical property.
Purified Starch may be separated from grains and
tubers by a process called wet milling. This procedure
employs various techniques of grinding, screening,
and centrifuging to separate the starch from fiber
, oil,
and protein.
Amylose
• Is a long chain-like molecule,
sometime called linear fraction. It
contributes gelling characteristics to
cooked and cooled starch mixture.
Amylopectin
• Has a highly branched, brushy type of
structure, very different from the
long, string-like molecules of
Amylose. Cohesion or thickening
properties are contributed by
amylopectin but this fraction does
not produce gel.

The resistance

3. RETROGRADATION

Oozing of
liquid from gel
when cut and
allowed to stand (e.g. jelly or baked
custard). The oozing of liquid from a
rigid gel; sometimes called weeping.
4. SYNERESIS
It is the process of
forming dextrin.
Dextrins – are partially
hydrolyzed starches
that are prepared by dry roasting. In home kitchens,
dextrinization is achieved by toasting flour for
polvoron, rice flour for kare-kare sauce, and bread
slices for breakfast.
5. DEXTRINIZATION
Starches undergo
hydrolysis during
cooking or processing
and during storage of food where a chemical
reaction in which a molecular linkage is broken
and a molecule of water is utilized.
6. HYDROLYSIS
• A plant (as a grass) yielding
starchy grain suitable for food;
also : its grain.
Whole Grain Cereal is a grain product
that has retained the specific nutrients
of the whole, unprocessed grain and
contains natural proportions of bran,
germ and endosperm.
Enriched Cereal are excellent sources of
thiamine, niacin, riboflavin, and iron.
Restored Cereal is one from either the entire grain or
portions of one or more grains to which there have been
added sufficient amounts of thiamine, niacin, and iron to
attain the accepted whole grain levels of these three
nutrients found in the original grain from which the cereal is
prepared.
