General description

Natural occurence: Asparagus, baked potato, beer, cheddar cheese, cooked chicken, tomato and pumpkin
Methional is the main sulfur-containing flavor compound in potatoes.
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives . This product is a Biobased products, showing key improvements in Green Chemistry Principles “Less Hazardous Chemical Syntheses” and “Use of Renewable Feedstock”.

Application

The nature of this compound will complement many savory flavors, including cooked vegetables like potato, muchroom, tomato, sauerkraut, asparagus, and onion; chicken, pork, bacon, fish, beef, stew, broth, and gravy; soy sauce; and some aged cheeses, especially cheddar.

Lactic acid bacteria were screened for methional production from 4-methylthio-2-ketobutanoate. Only Lactococcus lactis IFPL730 produced high amounts of methional. It was demonstrated that production of this compound was an exclusively enzymatic reaction. The present work describes for the first time
