Barley malt syrup
Barley malt syrup is a thick sweetener obtained from barley (Hordeum vulgare, family Poaceae) that has undergone malting.
During malting, the grains are allowed to germinate under controlled conditions, activating enzymes, especially amylases, which convert part of the starch into simpler sugars.
The malt is then extracted with water, and the resulting liquid is filtered and concentrated to produce a dark, viscous syrup with a characteristic malty flavour.
It consists mainly of carbohydrates, with a significant proportion of sugars, especially maltose, together with varying amounts of glucose and other oligosaccharides.
Compared with ordinary table sugar, it has a less intensely sweet taste, but this does not mean that it is low in sugars.
It may provide small amounts of protein and minerals, but its main nutritional role remains that of a concentrated source of carbohydrates.
Its maltose and other readily digestible carbohydrates may produce a relatively rapid glycaemic response, particularly when consumed in significant amounts.
Its dark colour and characteristic flavour result from malting, concentration and the heat treatments used during production.
Uses in Food
It is used as a sweetener and flavouring ingredient in bread, biscuits, baked goods, breakfast cereals, bars and malt-based foods.
In leavened doughs, it can provide fermentable sugars for yeast, helping fermentation and contributing to crust browning.
It is also used in sauces, glazes, marinades, malt beverages and confectionery products, where it provides a deeper, slightly toasted flavour.
It can partially replace sugar, honey or other syrups when a characteristic malty note is desired, but it should not be considered a low-sugar alternative.
Calories
It provides approximately 300–320 kcal per 100 g, with variations depending on concentration and water content.
Allergens
It is derived from barley and may contain gluten. Barley malt syrup is therefore generally unsuitable for people with coeliac disease, unless the specific product is formulated and labelled gluten-free.
Assessment
A natural sweetener with a characteristic malty flavour, useful mainly for its aromatic and technological properties, but still composed predominantly of carbohydrates and sugars.
Ingredient verdict: useful for flavour, fermentation and browning, but nutritionally it remains a sugar-rich syrup that should be consumed in moderation.
Cons: sugars and Allergen
