鳳梨酵素

鳳梨酵素（Bromelain）會分解口腔黏膜的蛋白質，這就是吃鳳梨時舌頭會發麻或「咬舌頭」的原因。

Pineapple enzyme (Bromelain) breaks down the proteins in your oral mucosa, which is why your tongue feels numb or "bitten" when eating pineapple.

鳳梨酵素與口腔蛋白的互動 / Interaction Between Bromelain and Oral Proteins

• 蛋白質分解 / Protein Digestion: 鳳梨酵素是一種蛋白酶（Protease）。當它接觸到口腔時，會開始分解舌頭表面和口腔黏膜上的糖蛋白質保護層。
  Bromelain is a protease that breaks down the protective glycoprotein layer on the surface of your tongue and oral mucosa.
• 組織刺激 / Tissue Irritation: 當這層保護性屏障被稍微分解後，鳳梨本身的酸性物質（如檸檬酸、蘋果酸）會直接刺激敏感的黏膜組織，進而產生刺痛、發麻或流血的感覺。
  Once this protective barrier is slightly degraded, the natural acids in the pineapple (like citric and malic acid) directly irritate the sensitive tissue underneath, causing a tingling, numbing, or bleeding sensation.
• 人體修復 / Rapid Recovery: 口腔黏膜細胞的修復與再生速度極快，因此這種「被咬」的不適感通常在停止食用後幾小時內就會完全消失。
  The oral mucosa regenerates very quickly, so this uncomfortable "bitten" feeling typically disappears completely within a few hours after you stop eating.

如何減少鳳梨「咬舌頭」？ / How to Reduce the "Biting" Sensation?

方法 / Method	原理 / Principle
高溫加熱 Heating	鳳梨酵素在 60°C 以上會被破壞（失去活性）。例如：鳳梨蝦球、鳳梨苦瓜雞湯。 Bromelain is denatured at temperatures above 60°C (e.g., cooked pineapple dishes).
泡鹽水 Soaking in Salt Water	食鹽（氯化鈉）會部分抑制鳳梨酵素的活性，並能減少酸味。 Salt (NaCl) partially inhibits enzyme activity and reduces acidity.
塗抹食鹽 Applying Salt Directly	吃之前在鳳梨表面稍微抹一點鹽巴。 Rubbing a tiny amount of salt onto the pineapple before eating.
搭配蛋白質食物 Pairing with Proteins	與優格、肉類一起吃，讓酵素去分解食物中的蛋白質，減少對口腔的攻擊。 Eating it with yogurt or meat so the enzyme digests those proteins instead of your tongue.
