Content of Protein, Fat and Solid Non Fat Pasteurized Goat Milk in Refrigerator Storage

Abstract

Abstrak Penelitian bertujuan untuk mengetahui pengaruh lama simpan refrigerator terhadap kadar protein, kadar lemak dan solid non fat (SNF) susu kambing pasteurisasi. Penelitian ini telah dilaksanakan di Laboratorium Teknologi Hasil ternak, Fakultas Peternakan, Universitas Islam Malang mulai tanggal 01 Juli – 21 Agustus 2017. Materi yang digunakan adalah susu kambing, gula, alat pasteurisasi sederhana, refrigerator, lactoscan . Metode dalam penelitian ini adalah eksperimen. Parameter yang diamati adalah kadar protein, kadar lemak dan solid non fat (SNF). Pengujian kadar protein, kadar lemak, dan SNF menggunakan alat lactoscan . Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan 5 perlakuan lama simpan yaitu P1 (1 hari), P2 (3 hari), P3 (6 hari), P4 (9 hari), P5 (12 hari) penyimpanan dan 4 ulangan. Data yang diperoleh dianalisis dengan analisis of variance (ANOVA) dan dilanjut dengan uji duncan apabila terdapat pengaruh. Hasil penelitian menunjukkan adanya lama penyimpanan refrigerator mempengaruhi kadar protein, kadar lemak, dan SNF susu kambing pasteurisasi (P<0,05). Kadar protein, lemak dan SNF tertinggi pada penyimpanan P1 sebesar 4,26±0,01, 6,93±0,01, 8,30±0,01. Penyimpanan susu kambing pasteurisasi pada refrigerator selama 9 hari pada refrigerator menghasilkan kadar protein, kadar lemak dan SNF sesuai standar SNI. Kesimpulannya adalah penyimpanan susu kambing pasteurisasi pada refrigerator selama 9 hari masih dapat dikatakan aman untuk dikonsumsi.

This research was conducted in Animal Production Technology Laboratory, Faculty of Animal Husbandry, Islamic University of Malang from July 01–A u gust 21 st , 2017. Goat milk, sugar, simple pasteurization, refrigerator, lactoscan were used in this research. The obtained fresh goat milk was pasteurized at 71.2°C for 15 seconds. The storage of pasteurized goat milk was done in the refrigerator for 12 days. During storage, protein content, fat content and SNF were observed . Testing protein levels, fat content, and SNF using lactoscan. The experimental design used a complete randomized design with 5 treatments, i.e. P1 (1 day), P2 (3 days), P3 (6 days), P4 (9 days) , P5 (12 days) of storage. The data were analyzed by analysis of variance (ANOVA) and continued with Duncan test if there was significant effect. The results showed that refrigerator storage significantly influenced protein level , fat level , and SNF pasteurized goat milk (P< 0,05). The highest content of protein, fat and SNF was achieved at P1, i.e. 4.26±0.01, 6.93±0.01, 8.30±0.01, respectively. As conclusion, based on content of protein, fat and SNF pasteurized goat milk stored at refrigerator was still fulfill the requirement in SNI, thus the product was still safe for consumption.
