WHY CALCIUM

Why the World Needs More Calcium.
And Why It Matters.

Calcium deficiency is a growing nutritional concern worldwide and the impact is particularly evident in Asia.
In many countries, average daily calcium intake falls far below the recommended levels,
affecting both children and adults.

According to the International Osteoporosis Foundation (IOF),
this deficiency contributes to long-term health risks,
including reduced bone density and increased fracture risk.

WHY CALCIUM
WHY CALCIUM

Japan,

for example, is one of the many countries where calcium deficiency affects nearly 100% of the population.
More than 60% of individuals are aware of this issue, highlighting the urgent need for practical, food-based calcium solutions.

CALCIUM DEFICIENCY OF JAPAN

At Shiraishi,

we have developed food-grade calcium carbonate products specifically designed to help bridge this nutritional gap — safely, effectively, and reliably.

COLLO-CALSO-EX
  • Ca enrichment
  • Adding
    good texture

COLLO-CALSO-EX is a food-grade calcium carbonate developed through Shiraishi’s particle control technology. Its uniform particle size and excellent dispersion properties make it ideal for use in powdered food applications such as instant noodles, snacks, and confectionery

By integrating smoothly into flour-based systems, it enhances texture, improves crispiness, and ensures consistent product quality. In addition to calcium fortification, it contributes to the overall mouthfeel and bite of the final product.

Shiraishi supplies COLLO-CALSO-EX to nearly all major instant noodle manufacturers in Japan, — contributing to a growing global trend of calcium-enriched instant foods.

COLLO-CALSO-EX
  • Calcium fortification

    Improves the nutritional Value
    (400mg Calcium / 1g Collo-Calso-EX)

  • Excellent Dispersion

    Can be easily dispersed into powders (flour, etx.) due to its uniform particle size

Calessen-P

For Milk, Plant-Based Beverages, and Liquid Applications

Calessen-P
  • Ca enrichment

Calessen-P is an ultrafine calcium carbonate developed using Shiraishi’s advanced particle control technology. Engineered for high dispersion and low sedimentation, it is ideal for liquid applications such as milk, soy milk, and other beverages.

Even at high concentrations—such as 100 mg of calcium per 100 ml—Calessen-P disperses uniformly and remains stable with minimal settling. When homogenized at 15 MPa and combined with stabilizers like gum arabic, it retains a nearly unchanged dispersion for at least 8 days.

This makes Calessen-P a practical and efficient solution for calcium fortification in liquid food formulations, without compromising taste or texture.

Calessen-P
  • High Dispersion

    Disperses easily in liquids and stays in a dispersed state longer
    ( Homogenization and stabilizers improve the result )

  • Calcium Fortification

APPLICATIONS

How Our Calcium Carbonate Powers Food Innovation
Calcium carbonate’s versatility, safety, and functional performance make it an essential ingredient across a wide range of food categories — from dry snacks to liquid beverages.
Whether you're enhancing texture, improving processability, or adding nutritional value, our solutions are ready to support your product innovation.

APPLICATIONS 01

Instant Noodles
& Snack Foods

Texture enhancement, calcium enrichment, and mouthfeel optimization

In instant noodles and snack foods, calcium carbonate is widely used to strengthen the texture, add a pleasant bite, and improve crispiness.
It integrates easily into flour-based formulations and helps maintain consistent quality during mass production. This makes it especially effective for dry or fried noodle applications and snack coatings.

Instant Noodles & Snack Foods
APPLICATIONS 02

Confectionery

Crispy texture, whiteness,
and visual appeal

In confectionery applications such as biscuits, wafers, and sugar-coated products, calcium carbonate contributes to improved crunchiness and enhanced whiteness. Its consistent particle size supports even distribution in doughs or batters, helping ensure visual consistency and desirable mouthfeel.

Confectionery
APPLICATIONS 03

Processed
Seafood Products

Elasticity enhancement and
whiteness control

In processed seafood products like surimi or fish balls, calcium carbonate is used to improve elasticity and firmness, as well as to brighten the final product's appearance.
Its compatibility with protein-based systems makes it a practical solution for quality improvement in texture-sensitive applications.

Processed Seafood Products
APPLICATIONS 04

Powdered Foods

Anti-caking, flowability, and
calcium supplementation

In powdered foods such as drink mixes, spice blends, or meal replacements, calcium carbonate functions as an anti-caking agent and flowability enhancer.
It prevents clumping, improves handling, and simultaneously adds nutritional value through calcium enrichment — without altering flavor or color.

Powdered Foods
APPLICATIONS 05

Milk
& Plant-Based Beverages

High-dispersion calcium fortification
with minimal sedimentation

In dairy and plant-based beverages, precipitated calcium carbonate (such as Calessen-P) enables high-content calcium supplementation while maintaining smooth texture and long-term stability.
Unlike conventional calcium sources, it resists sedimentation and integrates well with homogenization and stabilizer systems.

TECHNOLOGY

Precision Technology for Optimal Performance

01

PCC

Precision-Crafted Through Advanced PCC Technology

At Shiraishi, we specialize in producing precipitated calcium carbonate (PCC) — a synthetic form of calcium carbonate that offers superior purity, consistency, and functionality compared to ground calcium carbonate (GCC).

Our proprietary production technology enables precise control over particle shape and size, allowing us to tailor our food-grade calcium carbonate to meet the specific performance and processing needs of various food applications.

Whether the goal is enhanced dispersion, improved workability, or optimized nutritional fortification, our PCC-based solutions deliver consistent, application-specific results.

02

GCC

Collo-Calso-WB ( Ground Calcium Carbonate )

A Cost-Effective Calcium Option for Food Applications

Collo-Calso-WB is a food-grade ground calcium carbonate (GCC) produced by finely grinding high-purity limestone.
Compared to precipitated calcium carbonate (PCC), it features a less uniform particle shape. However, it is carefully processed to meet strict food hygiene standards.

With approximately 400 mg of calcium per gram, Collo-Calso-WB is a highly efficient calcium source.
Its cost-effectiveness and ease of use make it a popular choice for a wide range of food applications—particularly where affordability is a key consideration.

This product is especially suitable for manufacturers seeking a balance between nutritional fortification and cost performance, without compromising on safety or compliance.
