ts-cooking-pathogens

This package contains classes to calculate units of common pathogens present after a procedure according to the D/z model and data from (van Asselt E D & Zwietering M H, 2006). It was created by following this guide.

Installation

Install from npm:

npm install ts-cooking-pathogens --save

Usage

import { Food } from 'node_modules/ts-cooking-pathogens/build/Model/Food';
import { meanInactivations } from 'node_modules/ts-cooking-pathogens/build/Data/InactivationValues';
// tslint:disable: no-magic-numbers

const meanFood = Food.New(meanInactivations);
const leastReduced = meanFood.CalculateLeastReduced([70,140], [3*60,5/60]);
const mostReduced = meanFood.CalculateMostReduced([70,140], [3*60,5/60]);
const reductions = meanFood.CalculateReductions([70,140], [3*60,5/60]);

console.log(meanInactivations.Campylobacter.CalculateLog10Reductions([70,140], [3*60,5/60]));
console.log(-Math.log10(meanInactivations.BacillusCereus.CalculateReduction(1, 140, 2 / 60)));
console.log(meanInactivations.BacillusCereus.CalculateLog10Reductions([140, 60, 30], [2 / 60, 3 / 60, 40 / 60]));
console.log(Math.log10(10 ** (((meanInactivations.ClostridiumBotulinumNonProteolytic.CalculateD(140)) * 2 / 60))));
