Abstract
Description
本發明關於一種農產品冷熱高壓循環冷縮密度擠壓方法,主要指一種可析出農藥並提升農產品口感之方法。The present invention relates to a cold-hot high-pressure cycle cold-shrinkage density extrusion method for agricultural products, and mainly refers to a method that can precipitate pesticides and improve the taste of agricultural products.
習知農產品種植過程一般噴灑農藥以防止昆蟲咬食並可提升產能,然而該農藥殘存於農產品上將影響食品安全及口感。Conventional agricultural products are generally sprayed with pesticides to prevent insects from biting and increase production capacity. However, the pesticide residues on agricultural products will affect food safety and taste.
以茶葉而言傳統的茶葉係由發酵、烘培的方式取得較佳風味,而近期亦具有可由熱對流方式或由遠紅外線抽真空等改進方式減低茶葉苦、澀口感,並可較傳統發酵、烘培方式具更佳風味。As far as tea is concerned, traditional tea leaves have a better flavor through fermentation and roasting. Recently, it has also improved methods such as heat convection or far-infrared vacuum to reduce the bitter and astringent taste of tea, and can be compared with traditional fermentation. The baking method has a better flavor.
然而該改進方式減低苦、澀口感效果有限,因而仍有再改進需求。However, this improved method has limited effect in reducing bitterness and astringency, so there is still a need for further improvement.
