Mutu dan Umur Simpan Cookies yang difortifikasi dengan Hidrolisat Protein Ikan

Fish is a source of protein that can be used to fortify various food products. To simplify the process, fish protein can be provided in the form of hydrolyzed powder or fish protein hydrolysate (HPI). Research was conducted to determine the best amount of HPI to use in cookies production and to estimate its shelf life. Cookies were made with variations of HPI addition of 0% (control), 5%, 10% and 15%, and the best concentration was determined by a hedonic test of 30 panelists. Cookies with the best formulation were then tested for quality (proximate and microbiological) and shelf life was estimated using the critical moisture content approach. The cookies with the best formula were those with 5% HPI addition and had proximate values of protein content of 7,38%, fat content of 14,19%, moisture content of 4,09%, ash content of 1,56% and carbohydrate content of 72.77% and a microbial load (TPC) of 2,56x10 3 col/g. The estimated shelf life was 957 days or 2,62 years.
