The many properties of rice including its nutritional content,
neutral flavor, non-allergenic nature, digestibility,
and
functionality (extrusion, puffing, crisping, freezing and
thawing) make it a highly desirable ingredient in processed
foods. While rice stands apart from most grains because it
is generally consumed in its kernel form, its properties are
ideal components in the manufacturing of cereals, snack foods,
baby foods, frozen dinners, sauce thickeners and other products.
Each part of the grain has many uses.

Rice
Hulls:
Rice grains from the field are encased in hulls, which

abrasives and other products.

Rice
Starch:
Rice starch is present only in the endosperm of
the grain, making up 90 to 93 percent of the milled

in making sauces and desserts. It can also be
hydrolyzed to make sweet syrup.
