instance, physical, chemical,
biological, and enzymatic hydrolysis
methods. Commercially available
biopolymers include, for example,
polyhydroxyalkanoates (PHAs),
polyhydroxybutyrate (PHB),
polybutylene succinate (PBS), starch
blends, polyvinyl alcohol (PVA), and
polylactic acid (PLA).
2.4 Animal Feeds Although food
industry wastes can be used to
manufacture raw materials for animal
feeds, they sometimes yield lower
levels of nutrients, which are not ideal
for animal feeds. This is because
most dry by-products contain high
amounts of carbohydrates and fiber.
Even though carbohydrate is one of
the main sources of energy in animal
feeds, an excess of fibers may
adversely affect the digestive system
and provide an inadequate level of
energy for animals. Therefore, it is
necessary to add food supplements,
such as minerals or vitamins, into
these feeds. According to a recent
finding, if by-products are fermented
or heated first, such a process can
help readjust the balance of nutrients,
although some nutrients may persist
and cannot be removed. Hence,
careful study to determine various
potential results is recommended
before applying these by-products in
the production of animal feeds.
Department of Food Science and
Technology, Faculty of Agro-industry,
Kasetsart University, is currently
conducting a study concerning
applying industrial by-products from
mung beans processin industry,
which is one of the main raw materials
in plant-based products. The
research effort is looking into the
effectiveness of various extraction
methods, the biological properties,
the safety of extracted substances,
and further potential application in
other foods.
