This research was to conduct good formulation of microcapsule sweet potaoes β-carotene with incomparable of arabic gum-maltodextrin as encapsulant and evaluate it’s antioxidant activity on cookies. The result showed that the best formula was part of sweet potatoes β-carotene and part of five arabic gum-maltodextrin (75:25). This formula had 25.01 % of rendement, 52.66 % of encapsulated and 6.47 % unencapsulated. Cookie with 200 ppm white sweet potaoes β-carotene microcapsule can longer storage to rancid for 4583 days. The panelist favor level on color, textur, aroma and taste cookies with microcapsule of sweet potatoes β-carotene showed neutral and very like.ABSTRAKPenelitian ini bertujuan untuk membuat mikrokapsul β-karoten ubi jalar menggunakan kombinasi gum arabmaltodekstrin sebagai enkapsulan dan mengevaluasi kemampuan antioksidatif β-karoten ubi jalar setelah dibuat mikrokapsul yang diaplikasikan pada cookies. Formula mikrokapsul adalah satu bagian β-karoten ubi jalar dan lima bagian enkapsulan. Mikrokapsul β-karoten ubi jalar terbaik diaplikasikan pada cookies sejumlah 0 ppm, 50 ppm,100 ppm, 150 ppm dan 200 ppm. Hasil penelitian menunjukkan bahwa formula mikrokapsul terbaik adalah satu bagian β-karoten ubi jalar dan 5 bagian enkapsulan dengan rasio enkapsulan gum arab-maltodekstrin (75:25). Formula ini menghasilkan rendemen 25,01 %, β-karoten ubi jalar terkapsulkan 52,66 % dan tak terkapsulkan 6,47 %. Penambahan mikrokapsul β-karoten ubi jalar 200 ppm dapat menambah umur simpan cookies terhadap ketengikan. Tingkat kesukaan panelis terhadap warna,, aroma dan rasa cookies dengan penambahan 200 ppm mikrokapsul β-karoten menunjukkan netral sampai sangat suka.

Soy fiber concentrate (SFC) was isolated from soy flour by extraction in alkali solution (pH 9), centrifuged and washed the solid in ethanol 80% then in acetone 33%, and dried. Effects of soy fiber diet on physical and chemical properties of the rat digesta were evaluated. The objective of this study were (I) to determine the composition of the SFC , (2) to evaluate the effect of soy fiber diets on physical properties (water content and weight) and chemical properties ( pH and SCFA) of the caecal digesta in rats. Four groups of jive male Sprague Dawley rats were provided. They were given differ rent diets Le. soybean, low and high soybean fiber and control diets ad libitum for 21 days period. In the end of experiment they were killed, the caecum were cut and the caecal digesta were taken and analyzed for moisture content, weight, pH and SCFA concentrations. It was found that soy fiber concentrate contains 71.52% total dietary fiber (62.56% insoluble fiber and 8.96 soluble fiber). Weight and moisture contents of the digesta were not affected by the soyfiber diets, but the diets decreased the pH of the digesta significantly. The diet also did not affect the molar proportion of the SCFA. SCFA molar ratio of the caecal digesta were: 62-63: 26-27: 10-11 for acetic: propionic: butyric acid
