The health benefits of infused olive oil make it a good choice for infusing. Because infused olive oil is so widely used both at home and in the culinary industry, we'll show you how it in a wide variety of applications. However, it is important to select a neutral flavored oil such as canola, safflower or sunflower unless the flavoring goes well with olive oil (such as basil).
Cooking oils are quite hardy and have quite a long shelf-life, but because we're changing the pH and adding particles when infusing oil, the shelf-life can be reduced quite drastically depending on the flavor infusion used.
For items such as nuts, the oil has a tendency to go rancid quickly and thus has to be keep refrigerated and used within a week or two. There is also the risk of botulism if the oil is not prepared properly. All moisture must be evaporated. The more flavoring items used in the oil, the longer it will take to process. Keep this in mind when using delicate flavor items as the long process time of other ingredients could destroy the flavor of the delicate item and turn bitter. Follow this procedure on infused olive oil to eliminate any risks associated with botulism. Failure to do so could foster botulism bacteria and toxins inside the oil.
