Gelatin adalah protein turunan dari kolagen yang penggunaannya saat ini sangat meluas baik untuk industri pangan maupun non pangan. Gelatin dalam penelitian ini diaplikasikan sebagai bahan pengemulsi dan agen humektan pada produk herbal skin cream. Gelatin diekstrak dari tulang ikan tuna (Thunnus sp.) menggunakan cuka aren. Penelitian ini bertujuan untuk menentukan nilai sensoris dan viskositas produk herbal skin cream. Penelitian menggunakan rancangan acak lengkap, dengan 3 konsentrasi gelatin yaitu 3%, 5%, dan 7%. Penelitian terdiri dari uji sensoris menggunakan skala hedonik yang meliputi tampilan, aroma, dan kesan lembab, serta viskositas. Hasil penelitian menunjukkan bahwa tampilan produk memiliki kriteria agak suka hingga suka, aroma dan kesan lembab netral hingga agak suka, serta viskositas berkisar antara 64.000 hingga 92.500 cP. Perlakuan terpilih adalah produk yang diaplikasikan gelatin 7% memiliki nilai viskositas paling mendekati standar SNI yaitu 64000 cP dan nilai sensoris yang agak disukai.

Abstract
Gelatin is a protein derived from collagen that widely used in food and non-food industries. In this research, gelatin was applied as an emulsifier and humectant agent on herbal skin cream product. The sensory and viscosity value of this herbal skin cream were then evaluated. Gelatin was extracted from bone of tuna (Thunnus sp.) using palm vinegar. The concentrations of gelatin used as the agent were 3%, 5%, and 7%. The research consisted of evaluation of the sensory values using hedonic scales on the appearance, aroma, and moist impression as well as the viscosity. The results showed that the appearance of the products was favored by panelists regardless the concentration of the gelatin added. The aroma and moist impressions of products tended to be favored by panelists. The viscosity ranged from 64000 to 92500 cP. The preferred treatment was the 7% gelatin-treated formula which had the closest viscosity value to the standard of SNI i.e 64000 cP and the panelists’ preferred sensory values.
