Food & Water Analysis

JP Selecta food and water analysis equipment covers the most frequent analytical determinations in quality control laboratories of the agri-food industry, water treatment plants and official health inspection services. The range includes Soxhlet extractors, Kjeldahl distillers, fibre determination equipment, moisture analysers and ovens for ash testing. Microbiological culture media sterilization requires certified laboratory autoclaves.

The operating principle varies by method: Kjeldahl systems combine sulfuric acid digestion with ammonia distillation to quantify total nitrogen, Soxhlet extractors perform continuous extraction with volatile organic solvent, moisture analysers rely on mass loss by controlled heating, and ash equipment mineralizes the sample at high temperature in muffle furnaces. Methods are internationally consolidated in the AOAC INTERNATIONAL Official Methods of Analysis (22nd Edition, 2023).

The range includes automated Kjeldahl systems that determine nitrogen and crude protein content in food products per ISO 1871 on food and feed products (general guidelines for nitrogen determination by Kjeldahl method), specific extraction for cereals and pulses per ISO 20483, nitrogen determination in milk and milk products per ISO 8968-1, and fat determinations by continuous Soxhlet extraction. For moisture and ash determinations, see our laboratory ovens and muffle furnaces.

Applications cover routine quality control of processed foods (protein, fat, fibre, moisture, ash), nutritional labelling verification, physicochemical analysis of drinking and waste water per the Standard Methods for the Examination of Water and Wastewater (APHA/AWWA/WEF), and origin certification determinations. For official analytical methodology, see the AOAC Official Methods Program and the publications of the European Food Safety Authority (EFSA) on chemical contaminants.

Regarding food safety, the assessments of the EFSA Panel on Contaminants in the Food Chain (CONTAM) provide up-to-date scientific references on tolerable limits and detection methods. Official laboratories operate under ISO/IEC 17025:2017 accreditation with complete metrological traceability.

Manufactured in Abrera under triple certification ISO 9001:2015, ISO 14001:2015 and ISO 13485:2018, JP Selecta food analysis equipment includes initial glassware and reagents, official technical service specialized in the agri-food industry and support for method accreditation.
