KADAR VITAMIN A, ZAT BESI (Fe) DAN TINGKAT KESUKAAN NUGGET AYAM YANG DISUBSTITUSI DENGAN HATI AYAM BROILER

Abstract

ABSTRACT

The research objective was to know the influence of livers-substituted of chicken nugget on the content of vitamin A, Fe and the preferences. The design experiments of the research was completely randomized design with 5 treatments and 4 replications. The treatments are T0 = 0%, T1 = 10%, T2 = 20%, T3 = 30% and T4 = 40% respectively. The content of vitamin A and Fe were tested by UV-VIS Spectrophotometry method. The data were analyzed by ANOVA, if the treatments significant was continued by Duncan Multiple Range Test. The preferences were tested by 25 panelist. The data were analyzed by non-parametric Kruskal Wallis H-Test using SPSS software version 16.0, if the treatments significant was continued by Wilcoxon test. The average of the content of vitamin A are T0 = 8,44%, T1 = 13,13%, T2 = 16,51%, T3 = 21,02% and T4 = 23,90%; the content of ferum (Fe) are T0 = 12,06%, T1 = 10,40%, T2 = 9,13%, T3 = 6,08% and T4 = 5,42%; and the preferences are T0 = 4,12%, T1 = 3,84%, T2 = 3,24%, T3 = 3,32% and T4 = 3,16%. The analysis showed significant (P < 0.05) to the content of vitamin A, Fe and the preferences.

ABSTRAK

Tujuan penelitian adalah untuk mengetahui pengaruh substitusi hati ayam pada pengolahan nugget ayam terhadap kadar vitamin A, zat besi (Fe) dan tingkat kesukaan. Rancangan percobaan dalam penelitian ini adalah rancangan acak lengkap (RAL) dengan 5 perlakuan dan 4 ulangan. Perlakuan secara berurutan adalah T0 = 0%, T1 = 10%, T2 = 20%, T3 = 30% dan T4 = 40%. Kadar vitamin A dan zat besi (Fe) diuji dengan metode Spektrofotometri UV-VIS. Data dianalisis dengan ANOVA, jika signifikan maka dilanjutkan dengan uji Wilayah Ganda Duncan. Tingkat kesukaan diuji oleh 25 panelis. Data dianalisis dengan non-parametrik Kruskal Wallis H-Test dengan menggunakan software SPSS versi 16.0, jika signifikan maka dilanjutkan dengan uji Wilcoxon. Rata-rata kadar vitamin A adalah T0 = 8,44%, T1 = 13,13%, T2 = 16,51%, T3 = 21,02% dan T4 = 23,90%; kadar zat besi (Fe ) adalah T0 = 12,06%, T1 = 10,40%, T2 = 9,13%, T3 = 6,08% dan T4 = 5,42%; dan tingkat kesukaan adalah T0 = 4,12%, T1 = 3,84%, T2 = 3,24%, T3 = 3,32% dan T4 = 3,16%. Hasil analisis menunjukkan signifikan (P < 0,05) terhadap kadar vitamin A, zat besi (Fe) dan tingkat kesukaan.
