Cereals & SnacksA Healthy Crunch for Extruded Snacks & Cereals

A Crisp Sensation and a Calcium Boost

PRODUCTS:

· Omya Calcipur® / Omya-Cal®

· Calcipur®

Pure enjoyment is no longer the only need that consumers have when

it comes to snacking. The role of snack products is expanding and

snacks are increasingly serving as a meal replacement. Simple ready-

made food solutions that offer indulgence are flying off the shelves in

supermarkets. The landscape for manufacturers is competitive. To be

successful, they will have to satisfy evolving consumer demands, for

better taste, texture and health impact.

Omya Calcipur® is a range of high purity Calcium Carbonate that can

help formulators to achieve their goals in multiple ways. Naturally de-

rived and available in a variety of mastered particle sizes, they not only

improve nutritional profile as a calcium source, but also the processa-

bility and texture of a vast range of sweet and savory snacks, including

breakfast cereals and extruded inclusions.

Benefits· Excellent source of calcium

· Natural nucleating agent & extrusion aid

· Improves crispness

· Increases extrudate expansion

With 40% of available elemental calcium, it only takes

1/4 gram of Omya natural Calcium Carbonate to provide

100 mg of elemental calcium: that equates to 10% of an

adult’s daily requirement.

Accordingly, up to five times less Omya Calcium

Carbonate is required to meet the same calcium content

and support any possible nutritional claim compared to

other available solutions on the market.

Excellent Source of CalciumOmya natural Calcium Carbonate is a bioavailable source with the highest elemental calcium content

Omya natural Calcium Carbonate food grade ingredients meet both E170 and FCC standards

Omya has developed tailor-made particles for use in extruded

food products. Whether in snacks or extruded cereals,

Omya Calcipur® acts as a nucleating agent, providing multiple

well-distributed surfaces in which gas bubbles can form

during the release of water vapor. The amount and size of

Omya Calcipur® can be tailored to offer the optimum quantity

and homogenous distribution of fine gas bubbles, improving

expansion and texture1.

Omya has a profound understanding of how Omya Calcipur®

can aid in the extrusion process of foods. Significant improve-

ments in crispness and texture can be obtained with just 0.5

to 1.5% of added Omya Calcipur®. Furthermore, even these

low concentrations already allow for a calcium claim to be

made on the final product.

Calcium Carbonate as a Nucleating Agent

Benefits· Very fine granulometry

· Improves texture & crispness

· Increases hardness & expansion index

· Ensures a homogenous bubble distribution

· Enhances taste perception (saltiness / sweetness)

CerealsThe organoleptic properties of cereals containing Omya

Calcipur® are described as crispy, light and fluffy. A concen-

tration of 1.5% Omya Calcipur® is suggested for the improved

crispness of extruded wheat-based breakfast cereals. The

crispness of extruded cereals can be improved by up to 45%.

Moreover, an enhanced perception of sweetness has also been

detected.

SnacksOmya Calcipur® can improve multiple parameters of

extruded snack properties. A concentration of 0.5%

Omya Calcipur® is recommended for an improved ex-

pansion index, increased hardness and good crispness in

corn-based snacks. This is an interesting solution when

making not only plain snacks, but also filled snack

products.

Moreover, snacks containing Omya Calcipur® show

prolonged crispness, less stickiness and also have an en-

hanced perception of saltiness. The snack surface is rough

but – thanks to Omya Calcipur® – more even, leading to a

homogenous appearance, especially at the cut edges.

· More gas cells and better distribution

· Improved snack expansion

· More even and homogenous snack surface

· Dosages as low as 0.5% already show effect

Figure 2:

The graph shows the role of Calcium Carbonate in

the expansion process. It represents the correlation

between the expansion index, the particle size and

the amount of Calcium Carbonate.

The expansion index is measured with the following

equation:

where FEI is the expansion index (dimensionless),

DE is the diameter of the extrudate (cm) and DD is

the diameter of the extruder dye (cm).
