冬笋的科学采挖与保鲜内容摘要:
2、占 30%以上,亩立竹 160200 株的竹林,冬笋产量高,可适量采挖。 四看笋形:“两头尖,中间弯逢春烂成浆;上头细、下头粗、来春成新竹。 ”笋形弯曲、基部呈尖状或笋壳开裂老化的笋,不能转化为春笋,可以采挖;基部丰满,根系发达,竹壳叶嫩而紧裹笋肉的,能转化为春笋,不应该挖。 贮藏保鲜的方法灶火煨熟贮藏法:把挖回来的冬笋,连壳埋放到火堆煨熟(用手捏笋发软无硬感)。 煨熟后取出,放到阴凉潮湿的地方竖排放好,食用时去其外壳,切成薄片,用水漂除苦味即可。 用此法保存冬笋,可贮藏保鲜 3545 天。 沙藏法:取一木桶或纸箱,底部铺上湿河沙 710 厘米厚,将完好无损的冬笋尖头朝上排列在木桶或纸箱中,再用河沙填满空隙,然后铺盖一层 710 厘米河沙,将冬笋的顶尖完全覆盖后,搬到阴凉通风处,可贮藏保鲜 3050 天不变质。 封藏法:取干净的冬笋装入坛或缸中,然后用两层塑料薄膜盖好并扎紧,使空气不易进入;或取不漏气的塑料袋,装好冬笋后扎紧袋口,放在阴凉通风处。 用此法保存冬笋,可贮藏保鲜 2030 天。 蒸制法:将挑选好的冬笋除去外壳并洗净,然后将大的冬笋切成两半,放在蒸架或清水锅中煮至成熟,取出摊放在竹篮子中通风,可保鲜 1015 天。 此法适用于破损冬笋或短时间内食用的冬笋。 专利查询。冬笋的科学采挖与保鲜
