01 / QUALITY & PLANT

Quality and plant

Quality comes from a repeatable process. Raw materials, strains and fermentation parameters sit inside one control logic, so every batch can be traced.

02 / PROCESS

The process we control

Raw material to finished product

Six steps, each with defined inputs and confirmation points.

  1. 01

    Raw material selection

    Sourcing

    Fruit and vegetable bases selected to the target category and flavour profile.

  2. 02

    Cleaning

    Preparation

    Impurities and interfering surface microbes removed.

  3. 03

    Crushing and juicing

    Extraction

    Crushed and pressed into a fermentable substrate.

  4. 04

    Inoculation and fermentation

    Fermentation

    Target strains inoculated with controlled time and temperature.

  5. 05

    Separation

    Clarification

    Liquid and solids separated to stabilise quality.

  6. 06

    Finished application

    Finished products

    Delivered as juice, jam, puree or beverage formats.

03 / PRINCIPLE

Four routes that run at the same time

Principle of fermentation

Strain selection and process parameters together determine flavour, acidity and functional compounds.

Yeast fermentation

Alcohol and esters

Builds the alcohol and ester backbone of the fermented flavour profile.

Lactic acid fermentation

Acidity and stability

Produces acid, lowers pH and supports preservation.

Flavour compound formation

Aroma and mouthfeel

New aroma and texture layers formed during fermentation.

Functional enhancement

Active compounds

Beneficial active compounds and more readily absorbed small molecules.

04 / DOCUMENTATION

Certification and documentation

Slots reserved for verified certificates

Certificate names, issuers and numbers must come from the certificate itself. The layout below is prepared for them.

  • Food safety management

    Certificate names, issuers and numbers are to be supplied by the client before publication.

    Status: awaiting client documents

  • Product certification

    Organic, halal, kosher or other product-level certification slots are reserved here.

    Status: awaiting client documents

  • Export documentation

    Health certificate, certificate of origin and other export documents listed once confirmed.

    Status: awaiting client documents

  • Plant and capacity data

    Fermenter volumes, annual capacity, plant area and production lines to be supplied by the client.

    Status: awaiting client documents

05 / DOCUMENTS

Six documents to request before ordering

Due diligence checklist

Together these cover most of the risk in contract manufacturing, and they are the fastest way to judge how a supplier is managed.

Business licence and production permit
Confirms the legal entity and whether the permitted scope covers the category you need.
Certification certificates
ISO 22000, HACCP, FSSC 22000 and similar — check the certificate number, scope and expiry date.
Product test reports
Third-party physico-chemical and microbiological reports; verify batch number and test date.
Ingredient and labelling files
Ingredient list, nutrition panel and label artwork, to confirm compliance in your target market.
Retained samples and traceability
Ask whether samples are retained and how deep traceability goes: raw material batch, fermenter number, filling time.
Shelf-life and stability data
Accelerated or real-time shelf-life data — critical for products claiming live cultures.
