Trehalose

Trehalose - stable disaccharide of natural origin

Trehalose is a naturally occurring disaccharide consisting of two glucose molecules. In nature, it protects sensitive cell structures from cold, heat or drought - for example in plants, fungi or insects. This stability also makes trehalose interesting for food production, for example in ice cream or baking-stable recipes.

In the human body, trehalose is broken down in the small intestine by the enzyme trehalase. The absorption of the glucose components is delayed compared to other types of sugar, which leads to a slow release.

Is trehalose natural?

Yes, trehalose is a natural part of the diet. It is found in edible mushrooms, honey, crustaceans such as prawns and in foods containing yeast such as bread or beer. It is produced industrially from starch by enzymatic conversion.

How does trehalose affect blood sugar levels?

Trehalose is broken down into two glucose units, which are only slowly released into the blood. As a result, the blood sugar level rises more slowly than with pure glucose or household sugar consumption. The release of insulin is also lower. The glycemic effect can vary from person to person - depending on the body's own activity of the trehalase enzyme.

Is trehalose suitable for diabetics?

Trehalose can be a suitable alternative due to its slower absorption. As the effect on blood sugar levels varies from person to person, it is advisable to consult your doctor if you have diabetes. Accompanying blood glucose monitoring can provide additional safety.

How many calories does trehalose provide?

Trehalose contains about 4 kcal per gram - comparable to other types of sugar.

How sweet does trehalose taste?

The sweetening power is around 45 % compared to household sugar. It has a subtle, clear taste with no off-notes and is well suited to sweetening mild dishes.

Why does trehalose not brown when heated?

Trehalose is a non-reducing sugar and does not take part in the so-called Maillard reaction, in which sugars react with proteins to produce browning and flavorings. Trehalose therefore does not caramelize - an advantage for light-coloured or colour-sensitive recipes.

Is Trehalose tooth-friendly?

No cariogenic effect has been found in previous studies. Trehalose does not appear to be as easily metabolized by oral bacteria as other types of sugar.

Is trehalose suitable for people with intolerances?

Trehalose is a pure source of glucose and does not contain lactose, fructose or gluten. It can therefore also be used in cases of lactose intolerance, coeliac disease or fructose intolerance. If you have an existing intestinal sensitivity, it is advisable to start carefully with small quantities, especially if you have recently been diagnosed with coeliac disease or if your symptoms have not completely subsided.

Can trehalose have a laxative effect?

Trehalose is well tolerated in normal amounts. In people with reduced trehalase activity, consuming larger amounts can lead to digestive problems such as flatulence or softer stools.

When should Trehalose not be used?

In the case of a rare trehalose intolerance - an enzyme deficiency in which the trehalase enzyme is only active to a limited extent - trehalose cannot be broken down properly. This can lead to digestive problems. People with this intolerance usually also react sensitively to mushrooms, as these also contain trehalose. Those affected should refrain from eating them.
