Abstract

Pengolahan es krim dengan penambahan berbagai macam buah atau sayuran dan bahan penstabil atau pengemulsi bertujuan untuk memperbaiki karakteristik fisika-kimia dan sensoris es krim. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ekstrak kelopak bunga rosela dan bahan penstabil terhadap overrun, kecepatan leleh, kadar vitamin C, dan karakteristik sensoris es krim yang dihasilkan. Penelitian dirancang menggunakan rancangan acak lengkap 2 faktor, yaitu jumlah ekstrak rosela (0, 20, 40, dan 60 g per 200 mL susu cair) dan jenis penstabil (karboksimetil selulosa/CMC, gelatin, dan karagenan, masing-masing 0,3%). Data dianalisis dengan sidik ragam dan dilanjutkan dengan uji beda nyata terkecil (BNT) taraf alfa 5%. Hasil penelitian menunjukkan bahwa kadar ekstrak kelopak bunga rosela berpengaruh nyata terhadap kecepatan leleh, kadar vitamin C, serta sifat hedonik dan mutu hedonik warna, aroma, dan rasa es krim. Sedangkan jenis bahan penstabil berpengaruh nyata terhadap overrun, kecepatan leleh, serta sifat hedonik dan mutu hedonik tekstur es krim. Interaksi antara kadar ekstrak kelopak bunga rosela dan jenis bahan penstabil berpengaruh tidak nyata terhadap semua parameter yang diujikan.

Abstract

The incidence of foodborne disease caused by street food in Indonesia tends to increase. Meatball served with tomato sauce is popular among elementary school students in Indonesia. This research examined the safety of the sauce used for meatball sold among the elementary school students in Samarinda. Rhodamine B and microbiological quality of the tomato sauce were examined from 25 vendors. Sanitation during the meatball preparation by each vendor was also questioned. Results showed that 79.2% of the vendor sold the meatball with Rhodamine B was positively detected in the tomato sauce. All sauce did not meet the requirements of the microbiological quality of Indonesian standard. It might be caused by cross-contamination of the pathogenic microbes from equipment, poor vendor sanitation while preserving the sauce, or the water used in the preserving processed. Contamination from air pollution also needs serious attention because the vendors sold the meatball in the street or by the roadside.
