milk replacer: formulation and use 代乳料-配方及应用

monica

In general .milk replacers are classified as “all-milk” of “alternative” protein milk replacers. All-milk-protein milk replacers should contain only milk ingredients such as WPC, dried whey, dried whey product(delactosed whey), dried skim milk, casein, or sodium (or calcium) caseinate. Alternative protein milk replacers will contain some portion of the nonmilk protein sources discussed earlier in this chapter and , as a result , are less expensive. A typical industry practice in formulation of alternative protein milk replacers is to
replace 50% of the milk protein with lower-cost nonmilk proteins. Recommendations about the acceptability of common protein sources are given in Table 2.
