Preclinical safety evaluation of Lipase OF from Candida cylindracea.

Triacylglycerol lipases are enzymes commonly used to process foods and beverages such as oils, wines, and cheeses through catalyzation of long-chain triglyceride hydrolysis. Lipase OF derived from Candida cylindracea (strain MS-5-OF) is only intended for use as a processing aid in food production applications; however, it may be present at trace levels in some products. As such, the safety of Lipase OF was evaluated in this study that included a bacterial reverse mutation assay, an in vitro chromosome aberration test, and a 90-day subchronic toxicity study in rats.

Toxicological evaluation of Phospholipase D from Kitasatospora paracochleata.

Phospholipases are used extensively in the production of food ingredients, typically as processing aids, to enzymatically convert glycerophospholipids and provide functional properties in meat products or baking confections. The current study examined the safety of Phospholipase D derived from Kitasatospora paracochleata (strain No. 362-PLD) for use as a processing aid in various food applications, where it may be present in the finished products at trace levels.
