苹果(学名:Malus domestica)是蔷薇科苹果亚科苹果属植物,落叶乔木。苹果的果实富含矿物质和维生素,为人们最常食用的水果之一。
苹果含有大量的果胶,这种可溶性纤维质可以降低胆固醇及坏胆固醇的含量。一中等大小未削皮的苹果可提供3.5克的纤维质(即使削了皮,也含2.7克的纤维质),是营养专家建议的每日摄取量的百分之10以上,而且仅含80卡路里的热量。《美国生理学期刊》的研究指出,在深红色的生果皮,如苹果及提子等,均验出有Resveraltrol。该物质可减少呼吸系统包括气管及肺部等的发炎,从而控制哮喘及慢性阻塞性肺炎等病症。
苹果中的果胶和鞣酸有收敛作用,可将肠道内积聚的毒素和废物排出体外。其中的粗纤维能松软粪便,利于排泄;有机酸能刺激肠壁,增加蠕动作用;而维生素C更有效保护心血管。苹果皮中富含多酚,多酚含有极佳的抗氧化作用,有助于抗老防癌。
扫盲anna apple
A very early season Golden Delicious style apple variety from Israel, noted for its very low chill requirement of less than 300 hours.
Anna is a Golden Delicious-style apple, developed in Israel specifically for cultivation in "low-chill" areas where winter temperatures rarely drop to freezing. Most apple varieties require 800 hours or more of winter temperatures in the range from about 6C / 45F down to freezing, in order to become dormant, which is an essential part of their annual cycle - this is the "chill requirement". Anna has an exceptionally low chill requirement, and will thrive even in climates where temperatures dip towards freezing for only 300 hours or so each winter. This makes it ideally suited to climates such as southern California and southern Texas which are in USDA zones 8-10. Anna is a very early-season apple, ripening in late June / early July. It bears fruit early in the life of the tree.
外形很像旧金山朋友家后院种的苹果哦,是不是菠萝格品种?您切开让我看看。
红富士苹果在我们这里超市现在大约是卖5-6块1斤,今年北方新苹果还没上市。现在超市苹果是从冷库里拿出来去年的苹果。刚上架的冷苹果表皮可见有水凝珠。
