Abstract: Producing high fructose corn syrup by apricot sauce was studied.It was indicator with transmittance of clarified apricot sauce juice, discussed factors affecting of the quality clarified juice through dilution, centrifugation, enzymatic clarification, ultrafiltration, resin purification, concentration, etc..Determine the relevant parameters that were diluted 2 times 30%to 32%the original sauce with water, were greater transmittance of Pectimex CL enzyme and Pectimex XXL enzyme that were 60mL/m 3, hydrolysis time was 2h, reaction temperature was 55℃, hydrolysis time was, and speed was 1.5BV/h and maximum 7.0BV of macroporous resin's injection.The results showed that it was 70%±2%in the total sugar, clarification transparent, 90.4%～93.1%in the recovery, in accordance with the national standard.
