摘要
收集华东省市当家的甘蓝型、白菜和芥菜型油菜籽品种２０个，经１０５℃３０分钟处理，小型６２机冷榨取饼，测定ＯＺＴ．ＩＴＣ，得出甘蓝型高硫葡萄糖苷品种在饼中的总苷量最高９．３６ｍｇ／ｇ，比苷蓝型低硫葡萄糖苷品种含总苷２．９５ｍｇ／Ｇ高出２倍。白菜型平均总苷３．１３ｍｇ／ｇ；芥菜型含３．５６ｍｇ／ｇ。以淮油６号、秦油２号菜籽作破碎或干热与否的前处理比较，总苷量以未破碎、未干热的菜饼最高，分别含９．８２ｍｇ／ｇ、１０．６４ｍｇ／ｇ；破碎又干热的菜饼总苷最低，分别为８．６９、７．０１ｍｇ／ｇ。以宁油７号品种为例用６２型冷榨总苷最高为１０．７７ｍｇ／ｇ，９５型其次５．１４ｍｇ／ｇ，２００型最低２．５５ｍｇ／ｇ。采集本省各地大、中、小型油厂、油坊的菜饼粕２１个样，２００型菜粕总苷为２．８ｍｇ／ｇｃｖ４５％，９５型３．３９ｍｇ／ｇ，ｃｖ３９．６％。２００型与９５型在加工过程中产生游离总苷量接近，分别为０．３８和０．４１ｍｇ／ｇ。由芥子酶或酶水解产生的腈类化合物以２００型的菜粕中含量高，平均含１３１８ｍｇ／ｋｇ，ｃｖ７９．７％；９５型含３１８ｍｇ／ｇｃｖ１３２％，其中３６％样本未检出腈量。菜饼粕单宁平均含０．８２％；植酸平均?
The principal 20 varieties of rapesceds with B. napus,B. Campestris and B. juncea in east-china werecollected and detcrinincd the contcnt of oxazolidimEthionE and Isothiocyanate using 62 type oil- press machine. Theresults showed as follow:1. The average content of glacosinolate (GS ) in B. napus of high GS,B. napus of low GS,B. campestris and B. juncea were 9.36mg/g,2.95mg/g,3.13mg/g and 3.56mg/g respectivcly.2. The GS lcvel in rapeseed Hua you 6￣# and qing you 2￣# were 8.69mg/g,7.01mg respectively after dry-heatand brokeness. It was less than 9.8 mg/g 10.64mg/g in the some variety of rapeseed without any treatment.3. Therc were some difference at GS lcvel by diffcrent type of oil-press-machine, The content of GS in Ning you7￣# using the 62,95,200 type oil-press-maehine were 10.77mg/g,5.14mg/g and 2.15 mg/g respectively. 21 varieties of rapeseed cake from oil-prcss plants(200 type ) and mills(95 type ) in Jinngsu province werecollected and detcrmincd level of GS ,nitrile,tannin and phytie. The result showed that the rapeseed cake cantained2.8 mg/g,3.39 mg/g at GS level,1318 mg/kg,318 mg/kg at nitrile level respectively and0.82%at tannin,1.24%at phytic level.
