Pre-Treatment dalam Proses Sterilisasi Gulai Domba Menggunakan Kemasan Retort Pouch di CV. XYZ
Abstract
Proses sterilisasi komersial dalam pengolahan pangan bertujuan untuk membunuh mikroba dan spora dalam kemasan hermetis sehingga dapat memperpanjang umur simpan produk pangan. Salah satu kemasan pangan steril komersial adalah retort pouch. Produk yang dikemas dengan retort pouch memiliki resiko pecah yang tinggi selama sterilisasi, sehingga perlu dilakukan proses perlakuan pendahuluan (pre-treatment). Tujuan penelitian ini adalah menentukan perlakuan pendahuluan berupa lama waktu perebusan daging dan suhu kuah yang tepat terhadap daya tahan kemasan dan mutu gulai setelah sterilisasi dalam kemasan retort pouch pada CV. XYZ. Pre-treatment yang diberikan dalam penelitian ini berupa suhu kuah gulai pada saat pemasukan ke dalam kemasan yaitu 60oC, 70oC, dan 80oC serta pre-treatment berupa lama waktu perebusan daging yaitu 5 dan 10 menit. Analisis yang dilakukan adalah pengamatan terhadap daya tahan kemasan, uji tekstur daging menggunakan Texture Analyzer, dan uji sensori menggunakan metode uji rating hedonik. Hasil penelitian menunjukkan bahwa seluruh kombinasi pre-treatment tidak berpengaruh terhadap daya tahan kemasan. Tekstur daging yang lebih empuk didapatkan pada pemberian pre-treatment berupa lama waktu perebusan daging 10 menit. Berdasarkan hasil uji sensori, secara keseluruhan panelis cenderung menyukai seluruh sampel dan rerata skor hedonik yang didapatkan tidak berbeda nyata satu sama lain. The commercial sterilization process in food processing aims to kill microbes and spores in hermetic packaging so as to extend the shelf life of food products. One of the commercial sterile food packaging is retort pouch. Products packaged in retort pouches have a high risk of breaking during sterilization, so it is necessary to carry out a pre-treatment process. The purpose of this study was to determine
the pre-treatment in the form of length of time to boil the meat and the appropriate temperature of the sauce on the durability of the packaging and the quality of the curry after sterilization in retort pouch packaging on CV. XYZ. The pre-treatment given in this study was in the form of the temperature of the curry sauce at the time of entry into the package, namely 60oC, 70oC, and 80oC and the pre-treatment in the form of boiling time of meat was 5 and 10 minutes. The analysis carried out was
observing the durability of the packaging, testing the texture of the meat using a Texture Analyzer, and sensory testing using the hedonic rating test method. The results showed that all pre-treatment combinations had no effect on the durability of the packaging. The softer texture of the meat was obtained when the pre-treatment was given in the form of a 10-minute boiling time. Based on the results of the sensory test, overall the panelists tend to like the entire sample and the
average hedonic scores obtained are not significantly different from each other.
