BBB, blacks, bits, browns.Source : From Ref. 1. 3.7 Packing and Storage Green coffee, after curing, has to be stored under suitable conditions to ensure proper appearance and saleability of the beans. The problems of appearance and color become more important, especially in plantation coffee. The main factors inuencing color andappearance in green coffee are moisture content and time and temperature of storage. Thecolor of the bean can be maintained satisfactorily at moisture level below 1%. The bluishgreen color of plantation coffee becomes bleached in coffee with moisture level above 7 Ramalakshmi and Raghavan Fig. 1 Electronic color sorter (Sortex).

Coffee can absorb moisture from the humid atmosphere and become soft, lose its color, and become susceptible to microbial growth and insect infestation during storage. Although large number of insects are potential pests of stored coffee, the most importantis the beetle Araecerus fasciculatus . It is generally accepted that Coffea arabica with less than 1.5% and . robusta with less than 1.0% moisture content are not likely to be attacked by this beetle (. In Brazil, dose of 3 to 1 aluminum phosphide tablets(Celphos) per ton with an exposure period of 2 has been tried to control all stages of this insect (1, . mixture of ethylene dibromide and methyl bromide has also been used successfully for fumigation of monsooned coffee. Other control measures adaptedare spraying of vacant premises with pyrethrin and fumigating of empty gunny sacks. Coffee should be stored inside well constructed godown. Godowns should be con- crete-oored, and uncured coffee and cured coffee should be stored separately. The storagetemperature and humidity in the godowns are the ma
