Abstract

Canning of mandarin orange (Citrus reticulata) segments using varying fillin- weight of segments and covering syrup strength was tried from oranges of Ambia and Mrug Hahar crops available in Nagpur region. The drained weight was directly proportional to the filling-weight of segments mid inversely proportional to the strength of the covering syrup. Reverse was the position with respect to cut-out syrup brix. The combinations of fill-in-weight and covering syrups which could give the required standards of 50% drained weight and cut-out syrup of }9° brix were identified. Mrug crop oranges gave higher drained weight and cut-out syrup brix than Ambia crop. Drained weight kept decreasing Upto 5 months storage at ambient temperature, except in packs were TSS contributed by the covering syrup was more than twice the TSS contributed by segments. Lower concentrations of covering syrup, where rss contributed by covering syrup was less than TSS contributed by filled segments, gave whitish turbidity in the cut-out syrup. Ascorbic acid loss was 23.46% during canning and 35·40% on storage for 10 months. Mrug Rahar oranges showed more breakage in canned segments than Ambia Bahar. Absorption spectra of caratenoids showed loss of colour on canning and more colour in canned Mrug crop segments than Ambia crop segments. Texture suffered badly with covering syrup of higher concentrations, above 5rr brix. Lower concentratons of covering syrup, 20_30° brix, maintained better Texture but the product was poor organoleptically.
