CBST Complex Sterilization Eco-friendly Sterilization Tech CBST+ Premium Sterilization Minimizes Color/Nutrient Loss

What is CBST Complex Sterilization?

An exclusive powder sterilization method developed through years of R&D

Introduction

  • The CBST Complex Sterilization Method refers to our proprietary sterilization process developed over many years, ensuring food materials are safe from harmful bacteria.
  • We supply safe, consumer-focused food materials by minimizing the destruction and alteration of nutrients through an eco-friendly sterilization method, avoiding chemical or high-temperature processes.
  • It utilizes a self-developed Microwave complex sterilization system, offering a safe alternative to irradiation or chemical sterilization methods.

Why is CBST Necessary?

Stability

The Most Important Condition for Food

  • Removal of harmful bacteria and viruses
  • Prevention of contamination of raw materials and finished products
  • Prevention of food poisoning
  • Eliminating concerns about food safety

Preservation

Prevention of Food Spoilage and Deterioration

  • Maintaining freshness
  • Preventing changes in taste
  • Preserving nutritional value
  • Extending shelf life

Eco-Friendly

Sterilization is Not an Option, It is Essential

  • Alternative to chemical sterilization methods
  • Alternative to radiation sterilization methods
  • Environmentally friendly production process

Food materials can be contaminated throughout the entire process, from receiving to production and shipping.
The One Nature researched and tested contamination environments at each stage to develop and apply the optimal Complex Sterilization Method (CBST).

Case Study: Pathogenic Fungi Detection

※ There have been reported cases where pathogenic fungi were detected in some fermented mixed grain products.

Pathogenic Fungi Test Report
  • The importance of hygiene management for powder raw materials was confirmed based on test reports from external agencies.
  • Pathogenic fungi can be effectively reduced and controlled when an appropriate sterilization process is applied.
  • Systematic powder sterilization at the raw material stage is essential to ensure the safety and quality of finished products.
  • Fungi and pathogenic fungi can occur due to external environmental factors during the cultivation, harvesting, drying, and storage of raw materials.
  • In particular, harmful microorganisms such as pathogenic fungi and E. coli may be detected in contaminated raw materials, unhygienic production environments, or unsterilized products.
  • Proactive and systematic sterilization management at the raw material stage is crucial to prevent such microbial contamination.

CBST Complex Sterilization Results

We aim for complete sterilization of various harmful bacteria such as E. coli (coliform) and pathogenic fungi, and manage the general bacteria count down to the level of 0~1,000 CFU.

What is CBST+ Premium Sterilization?

Premium sterilization process optimized for preserving raw material characteristics

Introduction to CBST+ Premium Sterilization

CBST+ Sterilization is an advanced premium powder sterilization process designed to minimize changes in the material's original color and active ingredients, focusing on preserving its natural properties.

✓ Minimizes original color alteration ✓ Minimizes active ingredient loss ✓ No chemical additives

CBST Complex Sterilization vs CBST+ Premium Sterilization

You can select and apply either CBST or CBST+ depending on the raw material characteristics and product application.
