Example 3
[0087] An analysis was then conducted to determine if the ฟีฟี produced by the
disclosed fractionation process are comparable to human มีมี or conventional infant formula globules.
[0088] Commercial infant formula, Enfamil Newborn (available from Mead Johnson Nutrition Company, Glenview, Illinois, U.S.) was used as a control and reconstituted and the fat globule particle size was measured (volume-surface average diameter) as having a mean of 1.555 µm and a median of 0.962 pm, with a mean to median ratio of 1.617. Another sample of Enfamil Newborn was prepared, this time ที่รวมถึง ฟีฟี prepared in accordance with this
การเปิดเผย in place of some of the fat source, and the fat globule particle size was measured as having a mean of 3.317 µm and a median of 2.747 µm
[0089] Each of the samples was then digested by lipase (pancreatin) for two hours, and the
free fatty acids measured. The control formula had a mean fat globule size of 20.41 µm and a median of 15.72 µm The free fatty acid content of the control was measured as 2.1%. The formula having the ฟีฟี derived from the fraction of the การเปิดเผยนี้ had a mean fat globule size of 8.549 µm and a median of 3.943 µm after digestion; the free fatty acid
content was measured as 4.1%.
[0090] Thus, the formula with ฟีฟี produced in accordance with this การเปิดเผย had a bigger fat globule size initially, but the fat globule size was less affected by digestion, showing minimal participation of proteins at the interface. Moreover, better digestion by the lipase was seen, as evidenced by the higher free fatty acid percentage.
[0091] Additionally, certain embodiments of this การเปิดเผย are directed toward a method for providing ไลปิด fractions derived from milk that may be combined to produce certain มีมี of a desired shape, size and/or ไลปิด composition.
[0092] Milk fractions produced after a fractionation procedure, such as the ones identified in Examples 1-2, may be selected and combined to create the มีมี. For example, milk fractions with differing ไลปิด concentrations and compositions may be combined to
formulate มีมี with a desired ไลปิด composition or size. In certain geographical
regions it may be desirable to have certain levels of one or more of the milk fat components to meet nutritional requirements for a เป้าหมายเด็ก in that region; those levels may differ from region to region.
