A sugar beet pulp based ingredient for pet food & aqua feed


Cuitu® is a feed ingredient produced with proprietary technology developed
by Bang & Bonsomer.

It is natural vegetable fiber based ingredient made of sugar beet pulp. Cuitu® creates a strong bond between other organic materials of the product, thus making it stronger and stabilizing the air pockets inside.

It improves digestive properties and the overall technical features of the product like grease and protein binding.

To put it simply – Cuitu® brings benefits both to production of feed and to the digestive system of animals.

The Raw Material


Wouldn’t you want that the raw materials used are 100% natural, even better

– vegetable fiber based and with a proven positive track record and nutritional value?

More than 30% of the world’s sugar is produced from sugar beet, from which the sugar is extracted with hot water. The plant residue, known as beet pulp, is the raw material for our Cuitu® production.

Sugar beet pulp is already used as such in various animal feeds and is known to be beneficial to the intestinal health of animals.

The Process


Cuitu® process is environmentally friendly, it utilises by-product streams from food industry, has a reduced carbon footprint and a larger carbon handprint.

How does it work


Enhanced structural stability

Prevents dust formation

Increased strength of pellets

Stabilises air pockets

Increased binding properties for grease and protein

The Gut Effect


In the animal’s digestive tract, the feed material becomes wet.

Because Cuitu® natural cellulose and adhesive molecules are water-loving (hydrophilic), they allow water to penetrate and swell the feed material.

Water permeation also introduces gastrointestinal enzymes into the feed material and allows controlled release of nutrients in the animal’s gut.

Cuitu® cellulose or adhesive molecules are digested in the lower digestive tract of the animal, where microbes are able to break down the fibres.

The microbes hydrolyse the carbohydrates in the glue molecules to a size suitable for microbial fermentation.

Lower gastrointestinal microbial fermentation is an important source of energy for the intestinal epithelium – it prevents the growth of harmful diarrhoea microbes and contributes to a healthy immune system in the animal. Cuitu® therefore contributes positively to overall gut health.

Cuitu® is a shear thinning material, in other words it is solid when at rest and liquid when in motion.

The digestive tract is in a periodic state of movement and rest – this is called peristaltic movement.

Cuitu® therefore undergoes numerous gel-to-liquid processes, during which it mixes with microbes and undigested waste products and thus efficiently passes through the intestine, increasing their elimination from the gut. This helps the intestine to protect itself against infection and inflammation.

Contributes to healthy immune system

Effectively transits waste material

The Right Fibers


Sugar beet is composed of primary cell wall cellulose rather than secondary cell wall cellulose, which is typical of wood cellulose.

The primary cell wall cellulose is soft, less crystalline, and contains a small amount of non-digestible lignin, in contrast to wood cellulose, which has completely opposite properties.

Therefore, sugar beet cellulose is more delicate for the lining of the digestive tract and acts as a lubricant for a continuously moving feed material. In contrast, wood-type cellulose is highly crystalline and abrades the intestinal epithelium.

Refined sugar beet pulp is even better.

The refining process reduces the dimensions of the pulp, but also makes the cellulose fibers hairy and curly, resulting in a gel rather than a solid material.

Such a gel structure has the ability to shift, unlike other dietary fibers. The shear thinning is important because it does not cause constipation like other viscous fibers, yet provides the benefits of increased viscosity at rest, such as microbial and waste entrapment, water retention, and good faecal consistency.

Cuitu® adhesive molecules are carbohydrate-based pectins and hemicelluloses,

commonly referred to as neutral detergent fibers, and are known to have positive prebiotic effects in the digestive tract.

The Cuitu® process even breaks them down to reduce their harmful viscotic effects, making them more readily available to gut microbes and having a positive impact on health.
