| dc.description.abstract | A research about encapsulation vitamin E PFAD on gum acasia and
galaktomanan kolang-kaling has done by using spray drying method. The
galaktomanan extraction of kolang-kaling is resulted 4.7%. In the initial preparation
is done the manufacture of film the mixture of galaktomanan kolang-kaling (GKK),
gum acasia (GA) and vitamin E PFAD with GKK variations 0.1 grams; 0.2 grams;
0.3 grams; 0.4 grams, GA 7 grams and 1.3 grams of vitamin E PFAD in a total volume
of 100 mL. The thick film is resulted from 0.600 to 0.780 mm, the mixture of most
compatible film is in comparison GKK : GA : vitamin E PFAD of 0.2 : 7 : 1.3 to 100
mL. This comparison is used in vitamin E PFAD encapsulation process by spray
drying method. The results obtained enkapsulation micro size with a diameter of 11-16
micron. GKK additions in the mixture will increase the percentage yield of
microencapsulation of vit. E from 53.15% (GA) to 64.09% (GA:GKK). Increasing the
oil content from 61.83% (GA), 62.44% (GA:GKK). Increasing the percentage of
vitamin E composition which was adsorbed 53.29% (GA), 53.76% (GA:GKK) after
spray drying. 49.23% (GA), 49.72% (GA:GKK) after 24 hours of 600C. 37.95% (GA),
39.53% (GA: GKK) after 48 hours of 600C. The increasing of oxidation stability by
decreasing the value of p-Anisidin 25.21 (GA), 16.17 (GA: GKK) after spray drying.
36.48 (GA), 29.63 (GA:GKK) after 24 hours of 600C. 47.52 (GA), 34.68 (GA:GKK)
after 48 hours of 600C. The low moisture is 3.40% (GA) and 3.08% (GA:GKK). The
addition of GKK on the mixing of formula provides good effect. | en_US |

acasia dan galaktomanan kolang-kaling dengan metode spray drying. Ekstraksi
galaktomanan dari kolang-kaling diperoleh sebesar 4,7%. Pada preparasi awal
dilakukan pembuatan film antara campuran galaktomanan kolang-kaling (GKK), gum
acasia (GA) dan vitamin E PFAD dengan variasi GKK 0,1 gram ; 0,2 gram; 0,3 gram ;
0,4 gram, GA 7 gram dan vitamin E PFAD 1,3 gram dalam volume total 100 mL.
Tebal film yang diperoleh 0,600 – 0,780 mm, campuran film yang paling kompatibel
adalah pada perbandingan GKK : GA : vitamin E PFAD sebesar 0,2 : 7 : 1,3 dalam
100 mL. Perbandingan ini digunakan pada proses enkapsulasi vitamin E PFAD dengan
metode spray drying. Hasil enkapsulan yang diperoleh berukuran mikro dengan
diameter 11-16 micron. Penambahan GKK pada campuran akan meningkatkan
persentase rendemen mikroenkapsulan vit. E dari 53,15% (GA) menjadi 64,09%
(GA:GKK). Meningkatkan kandungan minyak dari 61,83% (GA), 62,44% (GA:GKK).
Meningkatkan persentase kandungan vitamin E yang teradsorbsi 53,29% (GA),
53,76% (GA:GKK) setelah spray drying. 49.23% (GA), 49,72% (GA:GKK) setelah 24
jam 600C. 37,95% (GA), 39,53% (GA:GKK) setelah 48 jam 600C. Peningkatan
kestabilan oksidasi dengan menurunnya nilai p-Anisidin 25,21 (GA), 16,17
(GA:GKK) setelah spray drying. 36,48 (GA), 29,63 (GA:GKK) setelah 24 jam 600C.
47,52 (GA), 34,68 (GA:GKK) setelah 48 jam 600C. Rendahnya kadar air 3,40% (GA)
dan 3,08% (GA:GKK). Penamabahan GKK pada formula campuran memberikan
pengaruh yang baik. | en_US |
