ISO 18787:2017  Determination of water activity

Water activity is an often-overlooked yet crucial aspect of food safety and quality assessment. This crucial factor influences everything about food goods, including their flavor, safety, and shelf life. ISO 18787:2017 guarantees precise measurement of water activity. This international standard establishes the benchmark for calculating water activity in food to guarantee consistency and dependability throughout the industry.

    Importance of ISO 18787:2017

    A standardized technique for measuring water activity is provided by ISO 18787:2017, ensuring that labs and food manufacturers can obtain precise and repeatable findings. This is the reason that this standard is essential:

    Food Security: Water is necessary for the growth of microorganisms such as bacteria, mold, and yeast. By regulating water activity, manufacturers can improve the quality of food by preventing microbial development.

    Storage Life: Water activity influences the rate at which chemicals and enzymes react in food. By measuring and managing items, it is possible to prolong their shelf life and preserve their quality over time.

    Appearance and Taste: Physical characteristics of food are influenced by water activity. It may determine, for example, if a product gets soggy and stays crispy. Retaining the ideal texture and flavor profile requires maintaining proper focus concentrations.

    Administrative Compliance: Manufacturers can gain consumer trust and market acceptance by complying with ISO 18787:2017, which enables them to meet food safety standards and regulations set by health authorities.

    Implementation of ISO 18787:2017 Determination of water activity

    By incorporating ISO 18787:2017 into your quality control procedures, you may significantly improve the life span of food items, safety, and quality. The following are necessary implementations

    High Quality Equipment: Make sure your water activity meter is reliable and give it routine maintenance by calibrating and servicing it correctly.

    Train your Group: Teach your employees the value of water activity and the proper ways to measure it under the norm. 

    Standardize your methods: To guarantee uniform application throughout your processes, create and record Standard Operating Procedures (SOPs) based on ISO 18787:2017.

    Monitor and Modify: To maintain ideal levels, periodically check the water activity of your products and adjust your processes as needed.

    Adopting ISO 18787:2017 helps to meet international standards while also opening up opportunities to provide the market with safer, better-quality food items. Accept this standard and establish water activity measurement as a critical component of your strategy to ensure the quality of your food.
