扇贝出肉率低，带壳扇贝实际可食用部分（贝柱+裙边）通常仅占总重20-30%，买5斤带壳扇贝实际肉不足1.5斤，追求性价比可直接买冻干贝

Unverified出成率是判断真假的核心：正常整块牛腱卤制后出成率约50-55%（1斤生肉出0.5斤成品），若标称100g肉却极便宜或超软，多为注水/拼接重组肉77% similarUnverified纯冻干肉类零食（成分表仅1-2种肉/内脏）热量看似高但脱水后重量轻，实际单颗仅0.5-1.5kcal，是低卡零食的首选形态，优于淀粉基膨化零食75% similarUnverified肉粽看瘦肥比与肉块大小：优质鲜肉粽单个含肥瘦相间五花肉≥30g，肥膘经蒸煮融化渗入糯米才香；纯瘦肉粽反而易柴75% similarUnverified看净含量与固形物含量分开标注，红烧类肉菜包固形物（实际肉+菜重量）应≥55%，若仅标净含量300g而固形物含量低于50%，则近半是酱汁汤水74% similarUnverified五花肉肥瘦比约6:4至5:5，脂肪含量高约35g/100g，适合红烧、扣肉；里脊几乎无脂肪适合炒肉丝但易柴；梅花肉（猪肩胛）油花均匀，是家用煎炒兼顾嫩度和风味的最优部位74% similar
