In the food industry, precise measurements play an important role in product quality, process reliability and consistent results. Whether in the production of beverages, dairy products, meat products, baked goods or fermented foods: Monitoring relevant parameters supports reliable quality control throughout the entire production process.

The most important measured variables include the pH value, conductivity and other chemical and physical parameters that can provide information about the composition, stability and quality of a product.

Why are measurements important in the food industry?

Many manufacturing processes are based on precisely controlled conditions. Even small changes can have an impact on taste, consistency, shelf life or production processes.

Regular measurements help with this:

Monitor production processes
Ensuring consistent product quality
Recognize deviations at an early stage
document production batches
Optimize processes
Comply with quality standards

This is why measuring devices are part of the daily quality control in many companies.

The pH value in food

The pH value is one of the most important measured variables in food analysis. It influences numerous properties of a product, including taste, stability, fermentation processes and microbiological conditions.

Typical pH values of various foods are, for example:

Food	Typical pH value
Lemon juice	2.0 to 2.6
Yogurt	4.0 to 4.6
Beer	4.1 to 4.6
Milk	6.5 to 6.8
Drinking water	6.5 to 8.5

The actual values may vary depending on the product, formulation and manufacturing process.

pH measurement in fermentation and food production

The pH value often serves as an important control parameter in fermentation processes. Changes can provide information on the course of biological processes and support the assessment of production steps.

Typical areas of application are

Yogurt production
Cheese production
Brewing beer
Winemaking
Fermented vegetables
Food development

Conductivity in food production

Electrical conductivity (EC) is used in many production areas to monitor liquids and cleaning processes. It provides information about the concentration of dissolved substances and can contribute to process control.

Typical applications include:

Beverage production
Water treatment
Cleaning and CIP processes
Quality control of process water

Typical challenges in the food industry

Manufacturers are often faced with the following tasks:

Ensuring consistent product quality
Document production processes
Monitor fermentation processes
Control raw materials
Analyze process water
Check cleaning processes

Many of these tasks can be efficiently supported by regular measurements.

Recommended measuring devices for the food industry

Particularly suitable for applications in food production:

pH meters
Conductivity meters (EC)
TDS measuring devices
Multiparameter measuring devices

Apera Instruments offers precise measurement solutions for food manufacturers, laboratories, quality control and research applications. The devices enable fast, reliable and reproducible measurement results in a wide range of production environments.

Semi-solid foods require special electrodes that have a titanium coating on the tip, such as our LabSen753 and LabSen763 electrodes.
