Introduction: Patilo is one of traditional various snacks from Gunung Kidul that is made of fermented cassava waste and cassava starch. Fermentation is intended to reduce or eliminate the HCN content of cassava and to establish special flavour. The protein content of patilo is very low, therefore it can be enriched with animal protein from fresh water fish in form of fish flour or fish protein hydrolysate (FPH). Enrichment with fish protein hydrolysate has an advantage since it will be easier to digest by human because FPH better functional properties and higher solubility.
Method: The study consisted of four activities that were 1) making/producing mujair FPH, 2) producing and enriched patilo with mujair FPH, 3) analyzed the nutritive values and protein digestibility of enriched and unenriched patilo and 4) analyzed the consumers acceptability of the products. The experiments were carried out in the 1) Food Engineering and Chemistry Laboratorium of Faculty of Agriculture Technology Semarang University, 2) Pilot Plan PAU and GMSK Laboratory of Bogor Institute of Agriculture, 3) Sidoardjo Village, Tepus Gunung Kidul. Variables being studied were nutritive value and protein digestibility of unenriched and enriched patilo with mujair FPH in several consumer acceptability in terms of flavour, taste, colour and texture. The study design was a complete random design of one factor in which the FPH was added in 5%, 10% and 15% concentration, each treatment repeated 3 times. Statistical analyses used for nutritive value and protein digestibility were Anova followed by Least Significant Difference test with 0,05 level of significancy Friedman and Wilcoxon Sign Rank test were used to test the organoleptic values both in the laboratory and in the field.
Result:1) The nutritive value changes of raw enriched patilo were : a) significant decrease in water and carbohydrate content, b) significant increase in ash, fat and protein content compared to the unenriched patilo, 2) The nutritive value change of fried enriched patilo were : a) significant decrease in water and carbohydrate content, b) significant increase in fat, protein and energy content compared to the unenriched patilo, 3) The protein digestibility in raw and fried enriched patilo was significant higher than that without enrichement, 4) Patilo enriched with 10% mujair FPH was mostly liked by consumer either in the laboratory or in the field in term of taste, flavour and texture as for colour, all consumers prefered the unenriched patilo, 5) The changes of the nutritive values and protein digestibility were statistically significant in the enriched patilo, however from the nutrition point of view, only the increased of protein content (six folds increase) was meaningful.
Conclusion: Patilo enriched with 10% mujair FPH is the most/well accepted by laboratory panelists and field consumers, and there was six folds increase in the protein content.
Key Word: Patilo, enrichment and fish protein hydrolysate.
