市場需求 / Market Needs:
雞隻的飼料組成有玉米、黃豆粉、其他穀物、營養補充品及酵素等。但在豆類及穀物中存在抗營養因子主要為胰蛋白?抑制劑,會干擾多種酵素的分泌,造成吸收率變差,嚴重則影響腸道的消化吸收,致使動物對蛋白質的利用率下降造成生長受限甚至停滯。所以過量抗營養因子攝入對童子雞生長會顯著產生負面影響,使同日齡雞隻下降6%,若達到相同體重需至少增加3天時間。事實上殘存之抗營養因子是無法避免的,若要完全根除,很可能就過度加熱,導致蛋白質變性,降低蛋白質的營養價值。

Chicken feedis consistedof corn, soybean, grains, nutritional supplements and enzymes.The major anti-nutritional factorinlegume andgrainsis trypsin inhibitor, whichinterfere with the secretion of a variety of enzymes and cause poor absorption. In severe cases, it will affect the digestion and absorption of the intestinal tract, resulting in a decline in the utilization of protein in animals, resulting in growth restriction or even stagnation.When excessive intake of anti-nutritional factors will have a significant negative impact on the growth of chickens.As a result, the weight of chickens at the same age was reduced by 6% compared with the control group. If they want to reach the same weight, they must be kept for at least 3 more days.In fact, the remaining anti-nutritional factors are unavoidable. If it is to be completely eradicated, it is likely to cause protein denaturation due to excessive heating and reduce the nutritional value of protein.

 
技術摘要 / Our Technology:
對於胰蛋白酶抑制劑的清除是改善產品價值的重點之一,避免過度的負面影響。而傳統加工方法是利用高溫處理使蛋白質變性,但是會造成色澤變深、機能性成分含量降低的情況。為了避免上述缺點,以電漿既有的特性加入飼料製程,選定處理條件後在飼料營養成分保留、抗營養因子及酵素方面都有預期內的正向影響。

The removal of trypsin inhibitors is one of the key points to improve the value of the product to avoid excessive negative effects.The traditional processing method is to use high temperature treatment to denature the protein, but it will darkenthe color and reduce the content of functional components.In order to avoid the above shortcomings, the existing characteristics of plasma are added to the feed process. After selecting the processing conditions, the retention of feed nutrients, the reduction of anti-nutritional factors and enzymes have the expected positive effects.
