Food allergy versus food intolerance食品过敏源与食品不耐 食品过敏源与食品不耐 性
• Food allergy: the immune-mediated state of hypersensitivity resulting from exposure to a food-borne allergen (usually a protein or glycoprotein). Normally developing serious reactions and even causing deaths.

• Resistance to heat: 抗热性 – Most food allergens are resistant to heat. Fruit and vegetables are heat-labile and can be eaten after heating or canning. 大部分食品过 敏源抗热。水果和蔬菜遇热不稳定，可加热或制成罐头食品食用。 – Peanut and egg allergens remain stable when heated or boiled at 100 °C. 当加热或煮沸到100度时，花生和蛋类过敏源仍保持稳定。 – Milk retains its allergenicity through condensation, evaporation, and drying.牛奶在经过凝聚、蒸发和烘干后仍保留过敏性。 Acid stability: 酸稳定性 – Most allergens are stable to moderate acid treatments.大部分过敏 源经过温和的酸处理仍保持稳定性。 – Peanut allergens are stable at pH 2.8 and egg ovalbumin at pH 3.0. 花生过敏源在PH值2.8, 蛋类过敏源在PH值3.0的情况下仍保持稳定.

• Resistance to the digestive tract:抗消化系统能力 – Most food allergens are resistant to enzymes, acids and bile salts present in the stomach. 大部分过敏源对胃中的酶、酸和胆汁盐具有抵抗力。 – Fresh fruits and vegetables are easily digested in the GI tract and do not cause systemic effects.新鲜水果和蔬菜很容易在GI系统中消化并不会影响系 统。 Resistance to proteolysis, hydrolysis and digestion:抗水解蛋白质、水解和消化 – Food allergens are resistant to proteolysis and digestion (e.g. codfish, egg white).食品过敏源对水解蛋白质和消化有抵抗力（如鳕鱼、蛋白）。 – Extensive hydrolysis is necessary to eliminate allergenic properties of food allergens (e.g. casein, whey proteins, soybean).广泛的水解对于消除食品过 敏源的过敏特性是必要的（例如酪蛋白、乳清蛋白质和大豆）。 – Allergen inactivation depends on the enzymatic or chemical treatment used during hydrolysis and proteolysis.在水解或水解蛋白质时，可使用酶或者化 学处理办法使过敏源失去作用。
