World trade paprika and paprika products

Szabo (1969) has described the manufacture and quality of paprika oleoresin. About 50,000 tonnes of paprika are required for the production of oleoresin and colouring powder. Out of this, a major portion (20,000 tonnes) is produced and utilized in Spain alone (Anu and Peter, 2000). Spain also produces about 500 tonnes of paprika oleoresin. The next major producers of paprika are (1) Hungary, (2) Morocco, (3) Yugoslavia, (4) Czechoslovakia, (5) Chile, (6) Turkey, (7) Portugal, (8) Bulgaria, (9) Romania, (10) Greece, (11) China, (12) Mexico, (13) Israel and (14) South Africa. Paprikas from various countries are known by the names of the respective countries of origin. They include all forms of zero pungent types. In Europe, only two forms are recognized, the long Hungarian type and the round Spanish type. According to the Basic Synthite Chemicals, the paprika exporting firm in Kerala, though 75,000 tonnes of paprika such as Byadagi chillies and 9,000 tonnes of Tomato chillies are produced, very little is available in India for the manufacture of paprika oleoresin. There is an urgent need for the development of paprika varieties from the above two types. It is estimated that 470 tonnes of paprika oleoresin were exported from India (valued at Rs. 55 crores) during 1997-98 (Anu and Peter, 2000; Mathew et al., 2000).
