    There are serval ways for testing the egg's freshness.

    1) Candling

    Eggs are passed ove a strong light

    2) Plate test

    the egg is brick on the plate if it is fresh, the egg yolk is in dome shape,egg white is thick

    3) brine Water test

    the egg shinks it is fresh.If is float,it is stale as the air space has enlarged and water has evaporated. (姐係你講既鹽水test)

    如何判斷蛋是否新鮮?傳統的作法是從觸摸蛋殼﹐看蛋殼是否粗糙?粗糙的比較新鮮。對著光看﹐看得到裏面﹐蛋黃位置正常﹑氣室小的﹐或是泡在鹽水中可以沉下去的都是比較新鮮的。現在洗選蛋越來越多﹐已經無法憑蛋殼的觸感來評估﹐看它的洗選包裝日期也是一個方法。現在家家戶戶都有冰箱﹐藉由冷藏的方式﹐可以有效地保持蛋的新鮮。打破蛋殼﹐蛋黃有鼓起感覺的就是新鮮的蛋﹐扁平塌陷的就比較不新鮮。

    希望可以help到你!
