一、包蛋是什么意思
包蛋,全名是灰包蛋,這兩個名字大家比較陌生,不過說起它的另一個名稱——皮蛋,大家就(jiu)都比較熟(shu)悉了,其實灰包蛋就(jiu)是皮蛋的別稱。
皮蛋(dan)(dan)(dan)是一(yi)種中國特(te)有的食(shi)品,利用(yong)蛋(dan)(dan)(dan)在堿性(xing)溶(rong)液中,能使(shi)(shi)蛋(dan)(dan)(dan)白質凝膠的特(te)性(xing),使(shi)(shi)之變成富有彈性(xing)的固體,它一(yi)般以鴨蛋(dan)(dan)(dan)為原料制成,過強堿作用(yong)后,原本具有的含硫胺基酸被分解產生硫化(hua)氫及(ji)氨,再(zai)加上浸(jin)漬(zi)液中配料的氣味(wei),就產生特(te)有的味(wei)道了。
二、皮蛋為什么又叫灰包蛋
皮(pi)(pi)(pi)蛋(dan)有(you)(you)(you)灰(hui)(hui)包(bao)蛋(dan)的(de)別稱(cheng),這個名字的(de)由來與(yu)其做法有(you)(you)(you)關(guan):傳統皮(pi)(pi)(pi)蛋(dan)是以草木灰(hui)(hui)或石(shi)灰(hui)(hui)將蛋(dan)包(bao)裹起來腌制而(er)成(cheng)的(de),因(yin)(yin)此(ci)被稱(cheng)為(wei)“灰(hui)(hui)包(bao)蛋(dan)”或“包(bao)蛋(dan)”;至于皮(pi)(pi)(pi)蛋(dan)一名,也與(yu)制作工藝有(you)(you)(you)關(guan),因(yin)(yin)為(wei)老式(shi)加工皮(pi)(pi)(pi)蛋(dan)時要用生石(shi)灰(hui)(hui)包(bao)裹鴨蛋(dan)再沾上稻殼,就像(xiang)把鴨蛋(dan)穿上一件(jian)衣服(皮(pi)(pi)(pi))一樣,因(yin)(yin)此(ci)得名。
皮蛋還有一(yi)個松(song)(song)(song)花(hua)蛋(dan)(dan)(dan)的(de)(de)(de)(de)別稱(cheng),這則是(shi)(shi)與(yu)它的(de)(de)(de)(de)外形有關:因(yin)為(wei)皮(pi)蛋(dan)(dan)(dan)表面(mian)上(shang)有時會出現(xian)雪(xue)花(hua)狀的(de)(de)(de)(de)花(hua)紋,對于這種(zhong)花(hua)紋,有的(de)(de)(de)(de)地方稱(cheng)為(wei)“松(song)(song)(song)花(hua)”,因(yin)此得名(ming)松(song)(song)(song)花(hua)蛋(dan)(dan)(dan)。松(song)(song)(song)花(hua)蛋(dan)(dan)(dan)的(de)(de)(de)(de)松(song)(song)(song)花(hua)形成,主(zhu)要是(shi)(shi)因(yin)為(wei)腌(a)制過(guo)(guo)程中(zhong),堿性(xing)物質透(tou)過(guo)(guo)蛋(dan)(dan)(dan)殼表面(mian)的(de)(de)(de)(de)細微小(xiao)孔(kong)滲透(tou)到蛋(dan)(dan)(dan)內(nei)部,與(yu)蛋(dan)(dan)(dan)白(bai)(bai)中(zhong)的(de)(de)(de)(de)氨(an)基酸(suan)進行化學反(fan)應(ying),生成某種(zhong)氨(an)基酸(suan)鹽(yan),而(er)由(you)于蛋(dan)(dan)(dan)白(bai)(bai)的(de)(de)(de)(de)分子(zi)式和氨(an)基酸(suan)鹽(yan)的(de)(de)(de)(de)分子(zi)式在結構上(shang)差異很大,所以,氨(an)基酸(suan)鹽(yan)無法溶解在蛋(dan)(dan)(dan)白(bai)(bai)里,會以結晶體的(de)(de)(de)(de)形式析(xi)出,這就是(shi)(shi)我們所看到的(de)(de)(de)(de)“松(song)(song)(song)花(hua)”。
