[答]生四季豆(又名刀豆、芸豆)中含有凝集素。是一种毒蛋白,豆荚里含有溶血素。如烹调时未将豆炒熟、煮软,食后1～5小时有可能出现恶心、呕吐、头晕、腹胀痛等中毒症状,但充分加热后。由于蛋白变性便失去其原有的毒性作用。所以,只要在烹调时注意将豆炒熟、煮软,就能有效地防止中毒的发生。 [Answer] Health green beans (also known as sword beans, kidney beans) contain lectins. Is a toxic protein, pods contain hemolysin. Such as cooking not fried beans, boiled soft, 1 to 5 hours after eating may appear nausea, vomiting, dizziness, abdominal pain and other symptoms of poisoning, but after full heating. Due to protein denaturation it loses its original toxic effect. So, as long as the attention to cooking fried beans, boiled soft, we can effectively prevent the occurrence of poisoning.
