区分豆粕是否霉变的小窍门

发布日期:2016-08-25 14:13 来源:http://www.zdslgs.com 点击:

①看形状:优质纯豆粕呈不规则碎片或粉状,偶有少量结块。掺入了沸石粉、玉米等杂质后颜色浅淡,色泽不一,结块多,可见白 色粉末状物。另外,若豆壳太多,则品质较差。
The shape: high quality pure soybean meal was fracker or occasionally a small amount of powder, caking. The incorporation of zeolite powder, corn and other impurities and light colors, color, caking, visible white powder. In addition, if the beans are too many, the quality is poor.
②观色泽:优质豆粕为淡黄褐色至淡褐色,色泽一致。如果色泽发白多为尿毒酶过高,如果色泽发红则尿毒酶偏低。淡黄色豆粕是因为加热不足,暗褐色或深黄色豆粕是因为过度加热所致,品质均较差。
The concept of color: high quality soybean meal was yellowish brown to light brown, consistent color. If the color white is urease too high, if the color red is low urease. Soybean meal is due to lack of heating, dark brown or dark yellow due to excessive heating due to excessive heating, the quality is poor.
③闻味道:优质豆粕具有烤豆香味,不应有腐败、霉坏或焦化味、生豆腐味及豆腥味(新生产的豆粕有豆腥味)。而掺入了杂物的豆粕闻之稍有豆香味,掺杂量大的则无豆香味。加热严重过度时有焦糊味;加热不足的含在口中则有生大豆的腥味。
Third, smell: high quality soybean meal with the smell of baked beans, there should be no corruption, rotten or coking taste, tofu taste and beany flavor (new production of soybean beany flavor). And mixed into the debris of the soybean meal smell a little soy flavor, the amount of large amount of doping is not bean flavor. When heating seriously excessive burning; insufficient heating in the mouth is the smell of raw soybean.
④凭经验:安全水分内的豆粕用手抓时散落性好,水分过高的豆粕用手抓则感觉发滞。
The experience of water safety: scattered within the hands of soybean meal, soybean meal, too much water feels lag by hand.
