ABSTRACT
The roasted coconut products were used for component of many local
food, meals and sweetmeat. The intermittent texture and short-term storage of
roasted coconut were found in the market. The objective of this research was
investigated condition and packaging on roasted coconut shelf-life. The result
showed that normal and vacuum storage conditions at temperature of 30 and 4
°C and shelf-life at 0, 1, 2 and 3 months of roasted coconut using laminated bag.
It was found that, storage conditions, temperature and time storage affecting on
color of roasted coconut (L*
, a*
and b*
), moisture content and TBARS were
significantly (p≤0.05). The lightness, redness and yellowness of roasted coconut
were decreased, while the moisture content was tend to increase. However,
throughout the shelf-life gave the highest percentage of moisture content
(2.74±0.70) by weight which was less than Thai Community Product Standard set
(685/2547) value (< 5%). Initial TBARS was 2.53±0.23-2.67±0.09 mg MDA/kg and
slightly increased by the storage time including both of normal and vacuum
conditions combination with 30 and 4 °C of temperature. Yeast and mold had
less than 10 colonies per gram for 3 months of storage. Hence, the optimizing of
condition was vacuum at 4 °C could extended storage for 3 months and safety
for consumers.
