| 總結: | Redestilation of coconut shell liquid smoke used to preserve of natural
food, but it can damage during storage and less practically in handling, application
and distribution. Spray drying was a method to maintain its potency, improved
handling, applications and distribution of liquid smoke redestilation
encapsulation. Dextrin from sorghum, corn and rice bran were coating agent for
redestilation of coconut shell liquid smoke encapsulation. Dextrin sorghum, corn
and rice bran were expected to provide the properties and quality of coconut shell
liquid smoke redestilation microcapsules. The objectives of this study were to
investigate the properties and quality of liquid smoke redestilation microcapsule
using dextrin from sorghum, corn, and rice bran as wall materials.
Encapsulation of coconut shell liquid smoke redestilation was carried out
using spray drying with inlet/outlet temperature of 130/65ºC, respectively, feed
flow rate of 5 mL/minute with total soluble solid/TSS of sorghum, corn and rice
bran dextrin are 20, 25 and 30% w/v. Evaluation parameters were phenolic
staining, moisture content, yield, total phenolic compound, efficiency,
morphology, particle size distribution and volatile profile identification. Data was
taken triplicate for all parameters using completely randomized experiment
design. The best result was obtained using TSS of dextrin from sorghum and corn
20% w/v as well as TSS of rice bran 30% w/v. Increasing of total soluble solid
could decrease total phenolic, efficiency and yield of coconut shell liquid smoke
microcapsule using sorghum and corn dextrin, excepted rice bran dextrin.
Microcapsule morphology showed that particles less homogenity and
agglomerated. The particle size of sorghum dextrin 20% w/v was small and
retension of volatile compound was good. |
