Abstract： Ultra-high pressure processing is a non-thermal food processing and preservation technology， which is capable of inactivating pathogenic and food spoilage microorganisms by the mean of ultra-high pressures. It has potential to be widely used in the food industry to produce high quality and safety food without compromising its nutritional， functional and sensory properties. This article briefly introduces the principle of ultra-high pressure sterilization technology， and discusses the factors affecting the effect of ultra-high pressure sterilization.

Keywords： Ultra-high Pressure Processing（UHP）; sterilization; food processing

非熱加工是指利用傳統(tǒng)加熱以外的機制來滅活食源性微生物的新興食品保鮮技術，這些技術包括超高壓、脈沖電場、電離輻射和紫外線光等，它們最大的優(yōu)勢在于可在常溫或低溫下對食品中的病原微生物和致腐性微生物進行高效滅活，延長食品保質(zhì)期，同時不影響食物天然風味和口感。（剩余6392字）
