Abstract: The study made use of fresh pineapples of Hainan produce as raw materials and adopted popping explosion technology to manufacture a new type of instant pineapple chips. The major parameters including variety, different breeds, different sizes and thicknesses cutting maturation degree, operation temperatures, pressures, residence time and moisture contents were found through the single factor experiments. Educe the optimum craft parameters of the popping explosion of pineapple chips as follows: popping temperature 75 ℃, residence time 2~4 min, pressure 70 kPa, residence time 30 min, moisture content 20%.

Key words: popping explosion technology, pineapple chips, dilatability, rehydration rate, residence time
