摘要
蒸汽爆破(steam explosion,SE)是一种典型的物理-化学预处理技术,通过高温高压蒸汽瞬间释压破坏细胞壁结构,促进植物活性成分释放。由于加工技术的制约,许多农产品加工过程中产生大量副产物难以进一步利用,而这些副产品含有多种天然活性成分,具有较高的营养价值。近年来,将蒸汽爆破技术引入农产品加工副产物原料预处理中,可以明显改善天然活性成分提取率和增强功能活性。该文综述了蒸汽爆破技术原理与装备及其在植物活性成分提取和大分子物质改性中的应用,以期为加强农产品加工副产物综合利用提供参考。
As a typical physical-chemical pretreatment technology,steam explosion (SE) can destroy the cell wall structure by instantaneous release of high-temperature and high-pressure steam,promoting the release of plant active components.Due to the restriction of processing technology,a large number of agricultural by-products are difficult to be further utilized,while these by-products contain a variety of natural active ingredients and have high nutritional values.In recent years,SE technology has been introduced into pretreating agricultural by-products,which can obviously improve the extraction rates of natural active ingredients and enhance their functional activities.In this paper,the principle and equipment of SE technology,and its application in extracting plant active ingredients and modifying macromolecular materials were summarized,in order to provide references for strengthening the comprehensive utilization of agricultural by-products.
