Abstract
The lab experiments were conducted to study the effect of certain chemicals and
wax solution on storage behavior of Coorg Mandarin ( Citrus reticulata Blanco.) under
room temperature and cold storage at the Division of Horticulture, UAS, Bangalore. The
results revealed that the fruits coated with citrosol wax ( 18 % ) and stored under room
temperature and cold storage conditions recorded significantly higher fruit weight
(95.99g and 96.07 g ), maximum shelf-life ( 19.67 days and 45.67 days ), lower
physiological loss in weight ( 5.32 % and 5.21 %), higher juice content ( 40.89 % and
41.04 %), higher peel and rag weight ( 55.11 % and 55.03 % ), higher titratable acidity (
0.54 % and 0.56 %), higher ascorbic acid ( 32.67 mg/100 g and 32.03 mg/100g ), lower
TSS content ( 10.27 º Brix and 10.08 º Brix), lower total sugars ( 7.14 % and 7.52 %),
reducing sugar ( 2.86 % and 2.93 % ), non reducing sugar ( 4.28 % and 4.59 %) and
higher sensory scores for appearance of fruit ( 7.93 and 8.20 ), colour of fruit rind ( 8.22
and 8.34 ), texture of fruit ( 8.16 and 8.36 ), taste of segments ( 8.30 and 8.32 ) and
overall acceptability ( 8.28 and 8.31 ) after 18 days and 42 days of storage respectively.
In general, higher shelf-life and good quality fruits were obtained from cold storage
conditions compared to room temperature.
