.Sanitizing With Iodophor Solutions
Iodophor is effective at a concentration of at least 12.5 PPM, and at that strength, is an effective sanitizer with a contact time of one minute. Generally, the rule is to add 3 capfuls of Iodophor to a 5 gallon container of tap water. Test for maintenance of solution strength. FDA code 2001-4-501-114 (B) states that an iodine solution shall have a:
Some of the more modern Iodophor preparations are not pH sensitive, as they contain acids to keep the pH low. Iodophor is the least toxic of the common sanitizers, and can be used with confidence in settings where toxicity is an issue.
The best way to use Iodophor as a routine sanitizer is to really understand what is needed in terms ofstrength. This is why using our AQA 1227 Iodophor test kit is the key to really doing it the right way. Iodophor is used widely in the beverage industry, as it is very effective on glass and metal containers. It has a tendency to stain, so it is not used as a general, non-food-contact sanitizer or on surfaces that are susceptible to staining.
It is the least corrosive of all sanitizers, so its use on food preparation equipment may be recommended for that reason. The standard for Iodophor mixing is 25 PPM. Almost all food service suppliers that provide at least one brand of Iodophor sanitizing concentrates. Each one needs testing to be sure that appropriate concentration has been achieved.

Why Use Iodophor Strips?
The answer is simple: you don't always get Iodophor solutions of the right strength, even if you follow mixing instructions. Generally, concentrated Iodophor is very stable, but solutions that are stored may loose potency in a matter of days, especially with different pH and air exposure.
How to Mix and Use Iodophor Solutions
There are many different types of Iodophor concentrates, so there are no general guidelines for mixing. Most commercial containers will describe in detail how to mix the compound to a certain concentration, but it is always best to mix, then test.
A standard for time of exposure is 1 minute for most sanitizers, but Iodophor seems to have a more rapid effect. Iodophor has the most significant "residual effect" so quick dipping can be quite effective
Here is a guideline for mixing and using Iodophor solutions:
Clearly, it is difficult for any food preparation operation to "get it right" without some simple bleach strength testing procedure.
