Jeju · Origin of the raw material 33.49° N · 126.53° E · Lava-Seawater Complex

Jeju offers the naturalness and functionality

Jeju is a clean volcanic island of clear air, water and soil. Its citrus, broccoli, Dendropanax, Ecklonia and carrots carry exceptional active content, which BK bio turns into ingredients at our green-technology BioLabtory.

Jeju, in support of the process

From raw-material processing to product,
at the BioLabtory

Sourcing, development, low-heat processing and ingredient creation all happen inside BK bio's BioLabtory. The closer a Jeju field is to our line, the fresher the raw material stays and the less of its active content is lost.

Origin meets process

Fresh is only the start.
Cold keeps it.

A clean Jeju raw material loses its edge the moment it is processed hot. That is why the island and the line belong together: our cold-processed PEF extraction opens plant cells with electricity, not temperature, so the color, aroma and functional compounds Jeju gave the material are still there when it reaches your spec. The origin sets the quality; the process is what protects it.

From raw material to finished product

Stage 01

Extraction

PEF and low-heat extraction draws the active compounds from the raw material.

$Centrifugal thin-film separation of target fractions.$

Stage 02

Separation

Target fractions are separated from the crude extract.

$Plate-type circulation concentrator refining the fraction.$

Stage 03

Purification

The fraction is refined to a defined, repeatable purity.

Stage 04

Bio-conversion

Fermentation and bio-conversion raise the value of the active.

Spout-pouch filling of the finished product.

Stage 05

Processing

Concentration, blending and packaging into the finished form.

Machines

PEF (Pulsed Energy) System

Use: Beverage sterilization, active-compound amplification, tissue softening, extraction-yield improvement.
Spec: 1.0-10.0 t/hr
Features: Pulse Cell Breaker and cell-component extraction system.
Pulsed energy disrupts cell membranes for active-component extraction and sterilization.
Pulsed energy creates a potential difference inside and outside the cell membrane, causing membrane disruption.
Pulsed electroporation minimizes heat generation and enables effective sterilization while preserving the food's inherent color and aroma.
Enables amplification of beneficial functional substances and high-yield extraction.
Used for extraction, sterilization and new formulation development across food, cosmetics and pharmaceutical applications.
