Thermal Inactivation Calculator

Thermal processing remains the cornerstone of food safety, yet accessing reliable kinetic data and performing accurate calculations can be tedious and error-prone.

The Thermal Inactivation Calculator v3.0 streamlines this workflow entirely. It combines a powerful calculation engine with a curated database of D- and z-values for over 16 critical pathogens and spoilage organisms—all sourced from peer-reviewed literature.

The game-changing feature is CSV Import: upload your own comprehensive database to work with hundreds of organisms and conditions. Whether you're calculating pasteurization parameters, determining F-values for sterilization, or fitting experimental data to Weibull models, this tool delivers. With Monte Carlo analysis for risk assessment and one-click export for HACCP documentation, it's the essential companion for modern food safety professionals.

Dynamic Keeping Quality Model v4.0

Master Your Product's Shelf Life. The Dynamic Keeping Quality Model v4.0 empowers food professionals to predict and optimize product shelf life with scientific precision. Built on Arrhenius kinetics, this standalone HTML application transforms complex quality degradation science into actionable insights.

Four simulation modes address every analytical need: the Deterministic Model establishes baseline shelf life under specific temperature profiles; Monte Carlo Risk Analysis quantifies uncertainty through thousands of simulations with probability distributions; Multi-Stage Supply Chain Analysis identifies critical control points from production to retail; and Comparison Mode enables data-driven evaluation of products and scenarios.

With interactive Plotly charts, CSV export, and no installation required, this tool helps quality managers reduce waste, optimize logistics, and make confident decisions about product freshness. Take control of your supply chain and unlock precision shelf life management—all from your browser.

HPP Weibull Calculator

High Pressure Processing delivers safer, fresher food without heat—but validating these processes is complex. Microbial inactivation under pressure rarely follows a simple linear path, making traditional D-value models unreliable.

The HPP Weibull Calculator solves this challenge. Using the industry-standard Weibull model, it accurately predicts non-linear inactivation kinetics, including the shoulder and tailing effects that define real-world HPP behavior. The calculator dynamically adjusts parameters based on your specific pressure and temperature conditions.

What sets this tool apart is its flexibility. The built-in Data Fitting module lets you estimate Weibull parameters from your own experimental data, while CSV Import allows you to work with custom databases. Combined with Monte Carlo uncertainty analysis and scenario storage, this calculator transforms HPP process development from guesswork into science.

Microbial Growth Predictor v4.1

Proactive Food Safety at Your Fingertips. The Microbial Growth Predictor v4.1 brings predictive microbiology to your desktop, enabling proactive management of food safety risks. This sophisticated standalone application integrates the Baranyi & Roberts growth model with secondary models for temperature (CTMI), pH, water activity, and lactic acid inhibition.

Three specialized tabs serve distinct purposes: Database Records provides instant growth curves for pathogens across various food matrices; Interactive Modeling (PMP Style) offers real-time manipulation of environmental parameters to optimize formulations; and Extended LAB Modeling predicts the behavior of seven lactic acid bacteria species for fermentation and spoilage management.

Designed for food safety professionals and R&D scientists, this browser-based tool delivers accurate predictions without complex software installations. Make smarter, faster decisions to protect your products, ensure regulatory compliance, and safeguard consumers—all through an intuitive, interactive interface.
