Abstract:
1. A method of producing pectic enzyme treated pectin (PET-pectin), comprising: subjecting Citrus pectin solution to an enzymatic hydrolysis by using a mixed pectinase solution under an acidic condition of pH 4.0 and a temperature of 45 degree Celsius (° C.) for 12 hour to 48 hours, so as to obtain pectin hydrolysate, wherein the Citrus pectin solution has a pectin concentration of 1 percent by volume to 3 percent by volume, the mixed pectinase solution comprises pectin methyl esterase (PME), polygalacturonase (PG) and pectin lyase (PL), and a volume ratio of the mixed pectinase solution to the Citrus pectin solution is 1:1000; and subjecting the pectin hydrolysate to a thermal treatment under a temperature of 100° C. for 10 minutes, so as to terminate the enzymatic hydrolysis and obtain PET-pectin that is completely hydrolyzed, wherein the PET-pectin has an averaged molecular weight of less than or equal to 1 kilodalton (kDa), an averaged degree of esterification (DE) of 11.6% and an averaged diameter of 2000 nanometers (nm).
