| Summary: | Yellow yam is one kind of yam which is utilization was limited, but it
contains high levels of starch. The starch from yellow yam can be processed into
modified starch using acetylation method which can be applied as encapsulant in
food industries. One of food products that needs to be encapsulated is liquid
smoke, because there are compounds in liquid smoke such as phenol, carbonyl,
and acid which easily lost during storage. This research was aimed to know the
potential of modified starch made from yellow yam as encapsulant in liquid
smoke microencapsulation process and to know the comparison effect among
soluble solids of liquid smoke redistillate with modified starch on the efficiency
and the characteristics of microcapsules produced.
This study uses pH variations of initial starch slurry between 7, 8, and 9 in
the modified starch making process. The modified starch with the highest
solubility then used as encapsulant on liquid smoke microencapsulation process.
The microencapsulation used spray drying method with the ratio variations
between soluble solids of liquid smoke redistillate and the modified starch were
1:3, 1:4, and 1:5. The efficiency and characteristics of microcapsules that was
produced would be analyzed.
The result showed that the highest solubility is in the modified starch that
made with the initial pH of starch slurry was 8. The ratio variations between
soluble solid of liquid smoke redistillate and modified starch affected the
efficiency and characteristics of liquid smoke microcapsules. The more ratio of
modified starch were added, it will increased of capsulled compounds (phenols,
carbonyls, acids), acids levels, product recovery, and particle size of liquid smoke
microcapsules, but content of phenol levels, carbonyl levels, and solubility is were
lower. |
