| Description |
Blanched and unblanched samples of mandarin pulp and pomace were dried in either (i) a through-flow drier or (ii) a cross-flow drier; properties of the dried product and pectin prepared therefrom were then determined. Tables and graphs of results are given. The rehydration rate and ratio of dried pomace were greater than those of peel; dried peel had a higher swelling ratio than pomace. Powdering improved rehydration of both peel and pomace. (i) was faster, and gave better quality products than (ii). (i) did not significantly affect the yield or quality of pectin from blanched samples; (ii) reduced yield, and gave pectin of poorer jelly grade. (i) resulted in an increase in the water- and oxalate-soluble fraction and a decrease in the acid-soluble fraction in the pectin. [See also FSTA (1969) 1 4J309, 4J310 & (1972) 4 3J474.]
