醫案(an)日(ri)記 2023-06-19 06:34:29

青島長壽食品有(you)限公(gong)司經過3年探索與研究,研發出(chu)新型(xing)花生油及(ji)花生蛋白(bai)新技術。

據公司科研人員介紹(shao),“低(di)溫制(zhi)取花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)油(you)及花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)蛋白粉”技術,是采用物(wu)理(li)加(jia)工,花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)仁經(jing)精(jing)(jing)選、低(di)溫干燥脫(tuo)皮、冷壓榨,油(you)經(jing)物(wu)理(li)精(jing)(jing)制(zhi),花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)油(you)各項指標達到(dao)并(bing)超過國家(jia)一(yi)級花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)油(you)標準,花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)粕經(jing)超威粉碎成(cheng)(cheng)多(duo)功(gong)能食用花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)蛋白粉。該工藝生(sheng)產(chan)的花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)油(you)和花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)蛋白粉末受高溫影(ying)響和溶劑污(wu)染,最大限度地(di)保持花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)油(you)中天然營養成(cheng)(cheng)分和花(hua)(hua)(hua)(hua)(hua)(hua)(hua)生(sheng)蛋白的功(gong)能特性。

在傳統制油(you)(you)過程中(zhong),花(hua)(hua)生(sheng)(sheng)經(jing)過高(gao)(gao)溫壓榨和溶劑浸出后(hou),花(hua)(hua)生(sheng)(sheng)油(you)(you)雖能產生(sheng)(sheng)一(yi)定香味,但油(you)(you)的(de)營(ying)養成(cheng)分和花(hua)(hua)生(sheng)(sheng)粕(po)(po)中(zhong)蛋白(bai)質產生(sheng)(sheng)嚴重(zhong)變性(xing)(xing),尤其(qi)是(shi)經(jing)高(gao)(gao)溫處理后(hou),花(hua)(hua)生(sheng)(sheng)油(you)(you)中(zhong)的(de)各種維(wei)生(sheng)(sheng)素(su)、微(wei)量(liang)元素(su)等(deng)營(ying)養成(cheng)分受(shou)到(dao)破壞(huai),影(ying)響(xiang)其(qi)營(ying)養價值,浸出花(hua)(hua)生(sheng)(sheng)油(you)(you)受(shou)溶劑污染,脫溶劑工(gong)藝又降(jiang)低花(hua)(hua)生(sheng)(sheng)天然油(you)(you)溶性(xing)(xing)維(wei)生(sheng)(sheng)素(su)。傳統制油(you)(you)得(de)到(dao)的(de)花(hua)(hua)生(sheng)(sheng)粕(po)(po)其(qi)蛋白(bai)質高(gao)(gao)溫變性(xing)(xing),甚至參與美拉(la)德反(fan)應,花(hua)(hua)生(sheng)(sheng)蛋白(bai)粉中(zhong)水(shui)溶性(xing)(xing)蛋白(bai)質含量(liang)減少(shao),使其(qi)花(hua)(hua)生(sheng)(sheng)蛋白(bai)質親水(shui)性(xing)(xing)、乳化性(xing)(xing)、凝膠(jiao)性(xing)(xing)等(deng)功(gong)能特性(xing)(xing)大大降(jiang)低,失去(qu)了在食(shi)品加工(gong)中(zhong)需(xu)要的(de)功(gong)能特性(xing)(xing)應用價值。

另據介紹,此項技(ji)術(shu)解(jie)決了傳統花生(sheng)(sheng)加工中存在的花生(sheng)(sheng)油(you)蛋白粉中天(tian)然維生(sheng)(sheng)素的破壞、溶質殘留、黃曲霉(mei)毒素超標以及(ji)花生(sheng)(sheng)油(you)脂加工的工業三廢排放環境污(wu)染(ran)等技(ji)術(shu)難題。
