The rise of trehalose : what foods contain this mysterious sugar?

Abstract

As health-conscious consumers grow increasingly aware of the substances they ingest, one sugar that's been making headlines lately is trehalose. Trehalose, a naturally occurring disaccharide composed of two glucose molecules, has been recognised for its unique health benefits, including its role in neuroprotection, autophagy promotion, and cell preservation. But while its application in medicine and skin care is gaining ground, many are left wondering: what foods actually contain this sugar, and should we be seeking it out? Trehalose may not be as well-known as other sugars like sucrose or fructose, but it has been quietly working its way into various food products. From fungi to seafood, trehalose appears in diverse places in nature, with more and more of its sources making their way into the food industry. As researchers uncover its potential health benefits, there's growing interest in incorporating trehalose-rich foods into our diets. Let's explore where trehalose is found in nature, which foods contain it, and how it's being utilised in modern food production.
