Optimasi Formula Dan Uji Deskriptif Kuantitatif Minuman Jeli Carica Rendah Kalori

Abstract

Carica fruit (Carica pubescens, Lenne) which is a unique-typical fruit and well listed as a geographical indication product of Wonosobo region Indonesia has high content of vitamin C and potassium (50-100 mg / 100g; 125 ppm).
