ABSTRACT
The three southern provinces of Thailand are specific areas and there
have many interested foods. One of these products called “Ketupat”, which was
produced from white or black glutinous rice. It was soaked for 0.5-1.5 hours to
starch granule expand then cooked and stirred using coconut milk and flavored
with sugar and salt. Some regions, they added soy beans, red beans or Peeled -
Split Soy Beans into that ingredients to give the consumers for more acceptable.
Ketupat was wrapped with fan palm (Licuala) leaves with 2 and 3 triangular
shapes which depending to the producers according to the different peel off. The
important step to ripen the ketupat was the heat cooking methods by boiling or
steaming. These processes sterilized the pathogen and changed physical
structure of ketupat from uncooked gelatinous rice to cooked gelatinous rice
called “gelatinization”. Consuming ketupat will get nutritious source of
carbohydrate 52.38 ± 1.24%. While a little fat was 2.90 ± 0.01 % and fibers
content 3.24 ± 0.14 % which helps to excrete. However, ketupat had short
longevity as could not be stored at room temperature (about 27-30 °C) for more
than 2 days. Thus, packaging with polypropylene (PP) or laminated foil bags,
sealed with heat sealing machine then frozen at -18 °C. This condition helped
prolong shelf life of ketupat into one month. Frozen ketupat could be consumed
by defrosting with microwave machine at the power of moderate heating process
about 3-5 minutes, which had tasted and textured similar to those fresh ketupat
and safely consumed it.
