In this experiment we filtrate the optimum ingredient ratio based on research on Rose sterilis jam processing technic. The results indicate that the liquid ratio 1 : 0.7, sugar 50%, crtric acid 0.2%, pectin and xanthan gum and konjac gum 3-2-1 , composit thickener 0.4%, soluble solids 60%, pH 3.3,softness 227.56 g,density 827.73 g*sec. What's more, Rose sterilis has golden yellow color, and it is uniform, fine, suitable sour and sweet, delicious, with a special Rose sterilis smell.
