Excellent source of vitamins A & D?

Maybe the reason why many fluid milk processors don't proudly state "Excellent Source of Vitamins A and D" on carton labels is because they fear being tested and found noncompliant. The fact is, although vitamin fortification procedures for milk are relatively simple to implement and follow, it appears processors have a difficult time providing consumers with a properly fortified product.

Results from various analytical surveys, including an ongoing analysis at Cornell University, Ithaca, N.Y., support this theory.

The Cornell survey, part of the New York State Milk Quality Improvement Program, recently reported disappointing results that show little improvement in fortification compliance as compared to results from the first study published six years ago.

"Results of milk samples analyzed [in 1996] indicate only 33% of the milks fortified with vitamin A and only 38% of those fortified with vitamin D met the current federal standards (100-150% of label claim)," said David Bandler, Cornell professor of food science, when he addressed attendees at the 1997 Oregon Dairy Industries Conference this past April.

According to the study, 61% of 184 samples tested for vitamin A were underfortified and 6% were overfortified. Of the 146 samples tested for vitamin D, 59% were under and 3% over.

"Accurate vitamin fortification of milk to levels stated on the label is essential," said Bandler. "Vitamin levels below product label claims prevent the consumer from receiving the perceived nutritional benefits of the product, while excessive levels have the potential to be toxic."

Also, if the consumer press gets a hold of this information, the milk industry's reputation can take a hard hit. (Put this issue of Dairy Foods under lock and key when you're finished reading it.)

Improvement is inevitable

The standards of identity for lower fat milks become obsolete on Jan. 1, 1998. As a result, according to NLEA regulations for modified foods, it will be mandatory that lower fat milks be fortified with vitamin A to at least the level naturally present in whole milk (1,200 I.U./qt).

"With improved vitamin testing procedures and with the current emphasis on nutritional labeling issues, regulatory agencies are sure to take a more rigorous approach to enforcing the standards," Bandler said.

So let's do this right, and set an example for the food industry on label compliance.

To ensure proper fortification, Cornell researchers suggest the following:

* To prevent vitamin loss during processing, know if your vitamin concentrate is oil-or water-soluble and add it at the right step.

* Know the correct handling and storage procedures to ensure potency. Avoid heat and light. Rotate stocks. Don't buy large quantities and store for long periods of time.

* Add vitamins after standardization and before homogenization and pasteurization.

* Keep daily batch addition. Compare vitamin usage with volume of milk processed. A metering pump is preferred to batch addition. Calculate and calibrate delivery rate regularly. Inspect process daily.

* Limit the refortification of fortified rework.

Absorption of Liquid Vitamins

"Liquids, aside from offering the obvious benefit of being easy to swallow, have another very important trait. According to the Physicians Desk Reference,

Liquid is absorbed at a 98% rate, versus

Only 10 – 20% in hard capsules or tablet forms.

This very important distinction is extraordinarily important. It is not uncommon to have [hard] capsules pass right through the body in a way that the product name is still visible after the pill has left the body completely. This does not happen with liquids, as they are absorbed completely and are not wasted."

The National Advisory Board states that:

'100 mg consumed in tablet form translates to a minute stabilized 8.3 mg or 8.3% concentrated in the blood.'

This is simply not the case with liquids!"

"Pills and capsules may cost less, but in reality you get far less absorption for your money. No wonder they cost less!

Liquids are fast--you do not even have to wait for them to dissolve. They start working as soon as you swallow and

Many have very pleasant flavors."
