超市裏的速凍餃子有幾十塊錢一袋的也有七八塊錢一袋的,為什麽有的會這麽便宜呢?
今天,就來好好講講速凍餃子。
其實價格低的原因非常簡單,第一是因為大批量進貨,少了中間銷售環節,進貨成本減低。
第二就是速凍餃子一般都是機械批量化生產的,而且包裝也是機械化,這樣就大大降低了人工成本。
那我們去超市該如何挑選速凍餃子呢?
01、不買散裝速凍餃子
散裝速凍餃子雖然很便宜,但是它們的生產日期和保質期我們都看不到,質量就很難保證了。
02、不選冰霜多的餃子
餃子皮冰霜多,說明在運輸過程中,餃子皮經過擠壓或化了又凍上的過程,已經破裂,餃子內部的水分滲透出來結成冰霜。
03、選擇一個月內的水餃
速凍餃子選購時,生產日期越近越好,不要選擇超過一個月的餃子。因為簡裝餃子的保鮮技術可能不是很專業,所以最好選擇最近幾天生產的。
04、少買肉餡速凍餃子
不建議大家長期食用肉餡的速凍餃子,可能會有不良商家用豬肉的邊角料來做餡。
