Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh jenis dan proporsi tepung jagung terhadap sifat daya ikat air dan organoleptik dari nugget ayam kampung. Penelitian ini menggunakan rancangan acak lengkap faktorial yang terdiri atas 2 faktor. Faktor pertama ialah 5 (lima) jenis tepung jagung, yaitu: jagung kuning (J1); jagung pulen (J2); jagung ungu (J3); jagung Provit A1 (J4); dan jagung provit A2 (J5). Faktor kedua adalah prosentase penggunaan tepung jagung terhadap berat daging ayam yang dipergunakan, yaitu 10% (T1); 20% (T2); 30% (T3) dan 40% (T4). Dari kedua faktor tersebut diperoleh 20 kombinasi perlakuan, dimana setiap kombinasi perlakuan diulang sebanyak 3 kali. Pengaruh perlakuan terhadap sifat daya ikat air dianalisis menggunakan analisis kergaman, dan  dilanjutkan dengan uji beda nyata terkecil (BNT). Data kualitas organoleptik di analisis secara statistik deskriptif.  Variabel yang diukur meliputi analisis sifat fisik daya ikat air, dan organoleptik, meliputi: warna, tekstur dan kekenyalan, cita rasa, dan penerimaan umum. Hasil penelitian menunjukkan, uji daya ikat air dari nugget ayam kampung berada pada kisaran 47,75 – 61,64%, dimana perlakuan J2T3 (jagung pulen taraf penggunaan 30 %) memiliki prosentasi daya ikat air terrendah, sedangkan yang tertinggi pada perlakuan J5T4 (jagung provit A2 taraf penggunaan 40%).  Penggunaan bahan pengisi dari kelima jenis tepung jagung (J1, J2, J3, J4 dan J5) pada taraf 40 g (T1) diperoleh daya ikat air antara 50,02 – 55,36%. Hasil uji organoleptik terhadap nugget ayam kampung, menunjukkan bahwa kombinasi perlakuan J4T1 (jagung Provit A1 dengan taraf 10%) memperoleh nilai tertinggi untuk warna, tekstur, kekenyalan, dan cita rasa, dengan skor masing-masing 6,43, 5,69, 5,83 dan 5,86, sedangkan untuk kategori “penerimaan umum”, nilai tertinggi diperoleh pada perlakuan J5T3 (jagung Provit A2 dengan taraf 30%), dengan skor 6,00. Dari penelitian ini dapat disimpulkan, bahwa penggunaan bahan pengisi tepung jagung Provit A1 dengan taraf 10% (40 g) memberikan hasil nugget ayam kampung dengan karakteristik kualitas nugget ayam kampung yang terbaik.

Abstract

This research was purposed to find out the effect of durian seed starch addition (DuriozibethinusMurr) on chemical qualities and organoleptic properties of chicken meat balls based on chemical qualities (water content, protein and fat content) and organoleptic properties (texture, smell and taste). The result showed that the treatment P0, P1, P2, P3 gave a very significantly affect (P<0.01) on chemical qualities (water content, protein content, and fat content), gave a significantly affect  (P<0.05) on organoleptic properties (texture), but the addition of durian’s seed starch did not give significantly affect (P>0.05) on organoleptic properties (smell and taste). The best result was chicken meatballs made with addition of durian seed starch 15%, it has quality standart that suitable with SNI and acceptable for organoleptic properties. The conclusion of this research was addition of durian’s seed starch in chicken meatballs decreased water content, protein and fat content, also organoleptic properties. The optimum addition of durian’s seed starch on chicken meat balls were 15%.

Abstract

The objective of the study was to evaluate the influences of aging period, freezing temperature and packaging material on the frozen beef chemical quality. The material of the study was 2-3 years old Ongole grade beef of the Longissimus dorsi part,  and was then classified into 3 treat­ments, namely A (aging periode; 0, 12 and 24 hours), B (freezing temperature; -10°C and -20°C) and C (packaging material; aluminum foil (Al), polyprophylene (PP), poly­ethylene (PE) and without packaging material). The ob­served variables were water content, crude protein, fat, ash content. The data were analyzed by the Completely Randomized Design (CRD) in the Factorial (3x2x4) pattern. The results indicated that the aging periode de­creased the water content, and ash content significantly (P<0.05), and decreased the crude protein but increased the fat content insignificantly. The lower freezing temperature prevented the decreases of the water content, and ash content significantly (P<0.05), but prevented the decrease of crude protein, fat content insignificantly. The packaging material could prevent the decreases of water content, ash content sig­nificantly (P<0.05), but prevent the decreases of protein, and fat content insignificantly. A significant interaction (P<0.05) occured between the freezing temperature and packaging material factors on ash content of the frozen beef. The conclusion was the frozen beef without aging has a high of water content, protein, and ash, but has a low fat content.Temperature at -200C and using aluminium foil packaging can prevent decreasing quality of frozen beef. Keywords : Aging period, freezing temperature,  packaging material

Abstract

The aims of this study were to investigate the potential of local ginger for natural antioxidants on full-fat mayonnaise. The used materials were sunflower oil, vinegar, egg yolk, white pepper, salt, sugar, mustard, and local ginger extract. The study was done by using laboratory experimental with Nested Completely Randomized Design with 2 factors and 3 replications. The first factor was used three ginger varieties, namely elephant ginger/(Zingiber officinale var. Roscoe) (G), red ginger (M)/(Zingiber officinale var. Rubrum) and emprit ginger (E)/(Zingiber officinale var. Amarum). The second factor was the addition levels, which were 0.5% (a), 1% (b) and 1.5% (c). The observed variables include pH, viscosity, moisture content and antioxidant activity (IC50). Data were analyzed by using analysis of variance. The result showed that the used different ginger material and different levels of addition did not give significant effect (P>0.05) on pH analysis and gave highly significant effect (P<0.01) of the antioxidant activity, viscosity and moisture content. The study could conclude that mayonnaise added with red ginger showed physicochemical properties better than added with emprit ginger and gajah ginger. In addition, the best result was found in 1.5% ginger addition of each ginger variety in terms of physicochemical qualities of the mayonnaise.
