Lynside® ProteYn - The Alternative Source of Complete Protein from Yeast

April 25th, 2019

Building upon more than 160 years of experience in the yeast field, Gnosis by Lesaffre developed a true game-changer for the protein market, which is currently driven by animal and vegetable sources of protein.

Lynside® ProteYn is a source of high-quality proteins derived from yeasts. Designed to cater to modern consumers who are increasingly interested in non-animal sources of proteins, while seeking reassurance regarding the quality, safety and origin of the products they choose, Lynside® ProteYn is ideal for virtually any individual (time-crunched active adult, senior, dieter, etc.) wishing to increase his/her overall protein intake. The Lynside® ProteYn range is guaranteed non-GMO and free from anti-nutritional factors such as protease inhibitors, phytates, etc., and is produced without antibiotics for growth. Lynside® ProteYn is also vegan/vegetarian/flexitarian-friendly, gluten, soy and dairy free.

Unlike a majority of plant-based proteins, Lynside® ProteYn ingredients are a complete source of proteins containing all nine-essential amino-acids and comparing well with other protein sources. Indeed, their chemical score is above 100% and their Protein Digestibility–Corrected Amino Acid Score (PDCASS) greater than 1, which is similar to dairy proteins and much higher than all plant-based proteins. It is worth noting that Lynside® ProteYn contains significant amounts of all branched chain amino-acids (BCAA): Leucine, Valine and Isoleucine.

Beyond these outstanding nutritional properties, Lynside® ProteYn also offers the benefit of having a low environmental impact, thanks to a very specific and perfectly mastered manufacturing process. It can therefore be considered as a sustainable source of protein, compared to other more resource-intensive and environmentally impactful sources. This is particularly important considering the projected growth of the global population by 2050 which leaves the food & beverage industry faced with a major challenge: find a solution to meet the protein needs of nearly 10 billion people in a sustainable, affordable and healthy way.
