Wood-derived ingredients could be future of food, researchers say

From FoodBev.com

Manufacturers could soon be using wood-derived polymers such as xylan, fibrillated cellulose and lignin to improve the texture and reduce the energy content of food products, according to Finland’s VTT Technical Research Centre. The Espoo-based organisation said that the wood-derived ingredients could be used in yogurts, baked goods such as cakes and muffins, and meat products.

As the food industry searches for new natural ingredients that improve the quality of products and promote consumer health, its research has shown that the polymers have properties that make them stand out from their traditional counterparts.

Xylan, a hemicellulose extracted from birch pulp, could be used as texture enhancer in yogurt: VTT’s studies shown that xylan can improve the smoothness of yogurt and enhance its stability when compared to conventional manufacturing techniques.

Fibrillated cellulose, which is produced by wet-grinding cellulose fibres, forms a web-like gel that could be utilised as a thickening and stabilising agent for fermented dairy products – yogurt included. It may also reduce cholesterol in the human body.

VTT tested lignin in the manufacture of muffins and found that, in addition to giving muffins a fluffier texture, lignin proved to be a surprisingly efficient substitute for whole eggs and egg yolks. Lignin also functioned as an emulsifier in mayonnaise and contributed to juiciness in a meat product, VTT said.
