Method for producing milk product

A method is disclosed for producing an infant formula base, wherein by means of microfiltration, ultrafiltration, and nanofiltration the components of milk are separated into a casein fraction, a whey protein fraction, and a lactose fraction to produce, by suitably combining, a composition in which the amino acid composition is close to that of human milk. An infant formula base having a total protein concentration of about 1.0 to about 1.5% and a beta-casein concentration of at least about 11 % of the total protein concentration is also disclosed. The infant formula base is suitable for the production of an infant formula. 公开了生产婴儿配方产品基料的方法，其中通过微滤、超滤和纳滤将所述乳的组分分离至酪蛋白级分、乳清蛋白级分和乳糖级分，以通过适当地组合生产其中所述氨基酸组成接近人乳氨基酸组成的组合物。本文还公开了具有约1.0至约1.5％的总蛋白浓度和至少约11％的总蛋白浓度的β-酪蛋白浓度的婴儿配方产品基料。所述婴儿配方产品基料适用于生产婴儿配方产品。
