若是在北方,冬天的室外溫度通常在零下5攝氏度至零下19攝氏度,因此將肉放置于室外,可保存3至5天左右;由于北方在冬天有暖氣供應,室內溫度通常保持在20攝氏度,因此將肉放置在室內可保存1天左右。若是在南方,由于沒有暖氣,且冬天的溫度通常保持在5攝氏度左右,因此將肉放置于室外,可保存1至2天左右。

肉的鑒別***:

1、用眼看,豬肉注水后,表面看上去水淋淋的發亮,瘦肉組織松弛,顏色較淡;用手摸,注水豬肉由于沖淡了體液,所以沒有黏性;用刀切,注水豬肉彈性差,刀切面合攏有明顯痕跡,如腫脹一樣。

2、可用刀子在肌肉上切,一般厚度1厘米,長度20厘米,每隔一厘米切一刀,切四五刀后,在切面上仔細看,如發現肌肉上附有石榴籽一般大小的水泡狀物,即是囊包蟲。

3、一般凍結狀態時,顏色灰暗而無光,脂肪灰白;解凍后肉呈淡褐色,肉汁流失,組織松弛。
