Effects of low-dose. gamma. -irradiation on grapefruit products
Products obtained from Florida grapefruit irradiated with low-dosage ..gamma..-rays as a possible treatment for infestation by larvae of the Caribbean fruit fly were evaluated to determine effects on flavor and composition. Seven tests were run in which twenty-two lots of fruit were exposed to 7.5, 15, 30, 60 or 90 krd of ..gamma..-irradiation covering the 1981-1982 and early 1982-1983 harvesting season. There were few significant adverse flavor effects on products from irradiated fruit with the exception of the first test run on early-season fruit. In some cases, particularly at the lower doses of radiation, there was a significant improvement of flavor in grapefruit sections. There were no marked differences in vitamin C, sugar or acid levels in juice nor on essential peel oil composition of volatile constituents from irradiated fruit when compared with those from untreated fruit. 18 references, 2 tables.
