shelf stability of ready-to-feed infant formula
The current recommendation for newborns/premature infants not breastfed is to use sterile infant formula (not powdered) due to the threat of e.sakazakii. An interesting patent filed in 1999 states some of the problems with sterilized infant formula. Hopefully, these problems have been corrected.
Patent # 6039985 called, "Refrigeration-shelf-stable ultra-pasteurized or pasteurized infant formula invented by Kamarei and owned by Princeton Nutritionals.
"Since sterilized products are designed to have up to one and a half (1 1/2) year of room temperature shelf-life, such products will have a different actual content of degradable micro nutrients (vitamins) in the early part of its shelf-life as compared to the latter part. Thus an infant will obtain a different and unknown amount of vitamins depending on when the sterilized product is consumed."
"To account for degradation manufacturers of sterilized infant formulas often include up to 50% to 70% more of a given viatmin."
The problem with that according to the patent is that it changes the taste of the product and is costly to the manufacturer. My question would be what about the fat soluble vitamins? Vitamin D--overdose possiblities?? What about DHA and ARA?
