Unverified枸杞看产地和粒径，宁夏中宁枸杞多糖含量高、颗粒饱满（180-370粒/50g为特级），青海枸杞粒大但甜度偏高、多糖略低，警惕硫熏（颜色过于鲜红均匀）和染色（泡水掉色）81% similarUnverified宁夏中宁头茬枸杞（6-7月首采）多糖和甜菜碱含量高于秋茬，粒大肉厚，颗粒长度多在1.2cm以上，是药用和滋补首选；秋茬颗粒偏小、甜度更高但活性成分略低76% similarUnverified枸杞的等级常以颗粒数/50g划分，宁夏枸杞特优级约180-220粒/50g，颗粒越少代表越大越饱满；红枣干度以捏起来有弹性不发硬、掰开肉质金黄不发黑为佳75% similarUnverified枸杞规格用'每50克粒数'衡量，180-220粒/50g为中宁特优大果，280粒以上为普通果；粒数越少果越大越饱满，但大小不完全等于甜度，需结合产地判断72% similarUnverified选枸杞保健的标准路径：日常泡水→宁夏中宁220-280粒/50g干果；差旅/懒人→100%枸杞原浆(鲜果比≥5:1)；孕儿长期食用→有机认证干果；勿盲目追大颗粒和黑枸杞噱头72% similar
