酪蛋白磷酸肽（Caseinphosphopeptides，簡稱 CPPs）是以牛乳酪蛋白為(wèi)原料，經酶水(shuǐ)解、分離純化而得(de)到的含有(yǒu)成簇磷酸絲氨酸的多(duō)肽，可(kě)用于各種營養、保健食品中，能有(yǒu)效促進人(rén)體(tǐ)對鈣、鐵(tiě)、鋅等二價礦物營養素的吸收和(hé)利用，具有(yǒu)促進鈣質吸收、調節免疫等多(duō)重生(shēng)理(lǐ)功能。
Casein protein phosphate peptide (Caseinphosphopeptides, referred to CPPs) is polypeptide containing clustered phosphoric acid serine made from bovine casein by hydrolysis, separation and purification of the enzyme, which can be used in various nutritions and health foods so as to effectively promote the absorption and utilization of diatomic mineral nutrients (like calcium, iron, zinc etc.) in human body, having multiple physiological functions like promoting calcium absorption, regulating immune, and so on.
産品功能: Product Functions:
l 促進鈣質吸收 To promote the absorption of calcium
酪蛋白磷酸肽能有(yǒu)效防止鈣在小(xiǎo)腸中性或偏堿環境中形成磷酸鈣沉澱，從而促進鈣質吸收。
CPPs can effectively prevent the formation of calcium phosphate precipitation in neutral or alkaline environment of the small intestine, thus facilitating calcium absorption.
●促進牙齒、骨骼中鈣的沉積 To promote the deposition of Calcium in the teeth and bones
酪蛋白磷酸肽在溶液中能與鈣磷結合成複合體(tǐ)，附着在齲齒損壞處，維持高(gāo)水(shuǐ)平的鈣離子濃度，促使鈣離子進入齲損區(qū)，促進早期齲損再礦化，從而有(yǒu)效地防止牙蝕細菌的侵蝕，達到抗齲齒的作(zuò)用。
CPPs can bind with calcium and phosphorus in solution to form complexus to attch to the decayed tooth which can maintain a high level of calcium ion concentration, make the calcium ions into the decayed area, promote the remineralization of early caries, thereby effectively prevent erosion of tooth erosion bacteria to reach anticaries effects.
l 調節免疫 To Regulate the immune
酪蛋白磷酸肽通(tōng)過促進白細胞介素-5和(hé)白細胞介素-6的分泌，刺激B淋巴細胞增殖并分化成IgA生(shēng)成細胞。進而通(tōng)過調節淋巴細胞因子的水(shuǐ)平來(lái)調節動物的免疫功能。
CPPs stimulates b-cell proliferation and differentiation into IgA-producing cells by the production of interleukin-5 and Interleukin-6, and then to adjust the animal's immune function by adjusting the levels of lymphocyte factor.
l 調節腸道(dào)功能：To regulate the intestinal function
吸收快速，利用率高(gāo)，幾乎無排洩，全部被人(rén)體(tǐ)利用，不需耗費能量，減輕消化道(dào)負擔，有(yǒu)利于體(tǐ)弱者。
Fast absorption, high utilization rate, almost no excretion, are used by the body,without consuming energy, able toreduce the burden of the digestive tract, conducive to the infirm.
産品應用：Product application
●強化鈣、鐵(tiě)、鋅的營養保健品、奶制(zhì)品(果奶、學生(shēng)配方奶、高(gāo)鋅鐵(tiě)鈣低(dī)脂奶等)；Nutrition and health products fortified with Calcium, Iron and Zinc; Dairy products (fruit milk, student formula milk, low-fat milk with high Zinc, Iron and Calcium;
l 兒童營養食品：如嬰兒營養米粉、高(gāo)鈣餅幹等；Child nutritious food: eg, infant nutritional cereal, high Calcium biscuits etc.;
l 豆制(zhì)品：如高(gāo)鋅鐵(tiě)鈣豆奶粉、營養麥片、口香糖等；Bean products: eg, soybean milk powder with high level of Zinc, Iron and Calcium, nutritious oatmeal, chewing gum etc.;
l 防齲固齒的牙膏，啤酒、汽酒、含氣飲料等（可(kě)使泡沫細膩、持久，并促進其中的礦物質吸收）。Cavity protection toothpaste, beer, sparkling wine, sparkling drinks etc. (it makes foam delicate and lasting, and promote the absorption of minerals.)
