Fresh market tomato production is a $5 billion a year industry. Tomatoes are a warm season vegetable crop with large acreages grown in warm climates such as Florida and California. Tomatoes are also grown in numerous northern states earning premium prices for early production in cooler climates. Tomato production often employs plasticulture, such as the use of plastic mulches, for earliness and...

The purpose of this study is to review the effects of High Hydrostatic Pressure Processing (HPP) on the safety of different fruit derivatives (juices, nectars, jams, purees, pastes . . . ), considering the types established in the European legislation and some other vegetable-based beverages (mainly juices and smoothies).
