Overview
ARBOK-MILK BIOSAFE replaces or supplements conventional pasteurization with deep-vacuum processing at low temperature. Milk is treated under deep vacuum, at ambient temperature, instead of conventional pasteurization's 72–140 °C range, which cuts microbial load and inactivates pathogens without the thermal stress that denatures protein. The strategic objective is larger than pasteurization: a single vacuum platform performing biological safety treatment, degassing, concentration, stabilization, cheesemaking preparation and milk-powder preparation in one operation — turning dairy processing from a sequence of thermal stages into one low-temperature vacuum step.
Applications
Milk sanitation in place of or alongside pasteurization; preparation of milk for cheesemaking; production of next-generation milk powders and concentrates; recovery of excess water naturally present in milk; degassing.
Target pathogens: Mycobacterium bovis; Listeria monocytogenes; Salmonella spp.; Escherichia coli O157:H7; Brucella spp.; Campylobacter spp.
New product categories envisaged: Vacuum Protected Milk™, Vacuum Protected Cheese™, Vacuum Protected Whey™, ARBOK Dry Milk™, ARBOK Casein Concentrate™, ARBOK Milk Protein Concentrate™.
Operating Principle
Milk is processed under deep vacuum, at ambient temperature. Controlled phase-transition effects at reduced pressure reduce microbial load and inactivate pathogens without heating. Because the product never reaches pasteurization temperature, protein structure is preserved and post-process cooling is largely unnecessary. Dissolved gases are removed in the same operation, and concentration can proceed simultaneously rather than as a separate evaporation stage.

Architecture and Components
Deep-vacuum treatment chamber; no heat input and no temperature setpoint; vapour and dissolved-gas removal circuit; optional concentration stage.
The chamber and its ancillary circuits are configured as a modular processing line sized to plant throughput, integrating with existing dairy intake and downstream handling equipment.
Advantages
Technical: pathogen inactivation without thermal stress; protein structure preserved, including casein micelle integrity; dissolved gases removed in the same pass; concentration possible simultaneously rather than as a separate stage; greater tolerance to variable raw-milk quality.
Economic: reduced pasteurization cost; reduced cooling requirement; lower transport cost through water recovery; increased cheese yield; reduced protein losses; smaller processing footprint.
Logistical: extended shelf life and reduced dependence on strict cold-chain logistics.
Product: potential reduction of odour-causing compounds; enables a family of vacuum-protected dairy products not achievable through thermal processing.
Replaces or displaces: pasteurizers; deaerators; part of evaporator systems; part of spray-drying systems; milk-conditioning systems for cheesemaking; certain milk concentration processes.
Integrations
Arbok-DryMilk · ARBOK-REVITA · ARBOK FOOD PRESERVATION · ARBOK-VC (Vacuum Cracking)
Sits on the same deep-vacuum phase-separation core as the rest of the ARBOK platform, applied to the dairy profile.
Deployment & Operation
Deployment follows the standard ARBOK platform pattern: assay of the incoming milk stream, sizing of the vacuum unit to plant throughput, integration into the existing intake and cooling lines, commissioning, and handover to plant operators. The unit runs as a compact addition to an existing dairy line rather than a full plant rebuild, with automated operation and minimal additional staffing.
TRL
TRL 7 — confirmed 2026-08-06.
Scientific validation priorities identified: inactivation of Mycobacterium bovis; reduction of Listeria and Salmonella; impact on casein micelle structure; impact on whey proteins; enzyme activity preservation; shelf-life studies; antibiotic residue behaviour; organoleptic evaluation; nutritional retention.
Market Potential
The addressable case rests on displacing pasteurization, deaeration, part of evaporation and part of spray-drying with a single operation — that is, consolidating several capital-intensive stages of every dairy plant rather than competing with one of them. Every dairy plant of scale operates all of these stages today, which sets the addressable base at the full installed footprint of conventional thermal processing across the dairy industry.
Typical Project Economics
Value drivers identified: reduced pasteurization and cooling cost; lower transport cost through water recovery; increased cheese yield; reduced protein losses; smaller footprint; reduced cold-chain dependency.
Risk Factors
The listed research priorities are also the risk register: pathogen inactivation — particularly Mycobacterium bovis, the pathogen that pasteurization was originally designed against — is not yet validated. Dairy safety is among the most tightly regulated areas in food processing, and any replacement for pasteurization faces a long certification path in every jurisdiction. Effects on casein micelle structure, whey proteins, enzyme activity, shelf life, antibiotic residue behaviour, organoleptic properties and nutritional retention are all open questions in the base.
