The results showed that the yield of pectin increased with
increase in extraction time. The pectin yield was 7.96 g/100 g of
peel at 30 min boiling which increased to 9.06 g/100 g peel at
60 min boiling (Table 5). However, further increasing the extraction
time to 90 min did not increase pectin yield significantly. Thus, the
optimum time of extraction for the maximum yield of pectin was
found to be 60 min without affecting the quality of pectin in sum of
two extractions (14.83 g/100 g of dried peels). Similar results were reported on pectin extracted from mandarin orange peels by
