Thus, it is necessary to determine under which conditions equipment can be sterilised. Small motile bacteria penetrate far more easily through microscopic passages than non-motile moulds and yeast. It also assists operators by explaining the hazards that may reasonably be expected to occur during the use of food-grade lubricants and the actions required to eliminate these hazards or to reduce their occurrence to acceptable levels. A more general overview of composites, ceramics and glass and materials is provided.
Micro-organisms which are protected by product residues or biofilms are very difficult or impossible to inactivate and the same applies to process areas if resulting in a recontamination risk. The complete passivation guidelinee is described and environmental, as well as safety, concerns are discussed. This document explains the general principles of those guidelones processes above: Materials of construction ehexg equipment in contact with food.
The method is intended as a screening test for hygienic equipment design and is not indicative of the performance of industrial cleaning processes which depend on the type of soil.
The prevention and control of Legionella spp. Examples, with drawings, show how to avoid crevices, shadow zones and areas with stagnating product, and how to connect and position equipment in a process line to ensure unhampered draining and cleaning in-place.
Materials of construction for equipment in contact with food Buy Buy Buy Buy Buy Buy Buy Buy Buy First Editon, August – This guideline aims to offer a practical handbook for those responsible for the specification, design and manufacture of food processing equipment.
First Edition, April – The objective of cleaning validation is to prove that the equipment is consistently cleaned of product, microbial residues, chemicals and soiling, including allergens to an acceptable level, to prevent possible cross-contamination of hazards between products.
Hygienic design of pumps, homogenisers and dampening devices, The purpose of this document is to provide manufacturers, users and regulatory personnel with basic information and guidelines relative to equipment passivation.
Often one piping system is cleaned while another still contains product. Hygienic Engineering of Rotary Valves in Process Lines for Dry Particulate Materials Buy Buy Second Editon, May – Rotary valves are widely used in the food processing industry for continuous discharging, metering and dosing of dry particulate materials from or into attached plant components.
First Edition, October – The guideline is intended to provide guidance on hygienic design criteria for equipment manufacturers when designing the equipment and the plant for the fish industry during the procurement process and installation, plant design and microbiological sampling. Hygienic engineering of plants for the processing guidelihes dry particulate materials. This document describes a test procedure for assessing the in-place cleanability of moderately sized equipment, such as homogenisers.
Furthermore, with a minimum of product transfer between equipment, there are the added advantages of a more compact plant, lower energy consumption and reduced cleaning time.
This paper discusses the packing of food products that do not need aseptic packing but which nevertheless need to be protected against unacceptable microbial contamination. Attention is drawn to ways of preventing problems with joints, which might otherwise cause leakage or contamination of product.
It can serve as a guide for suppliers and users of this important component. General hygienic design criteria for the safe processing of dry particulate materials.
All documents downloaded or purchased are intended to be exclusively used by the EHEDG Member or ehevg guideline customer. Both organizations exchange their draft guidelines and standards for expert review and comments before publication. It mainly refers to the part of the weld in contact with the finished or intermediate product. First Edition, July – Abundantly illustrated, this paper provides guidelines for the correct execution of guidellnes hygienic sanitary welding between pipe segments, or between a tube and a guideoines component e.
Water is a vital medium used for many different purposes in the food industry. Thus, it is necessary to determine under which conditions equipment can be sterilised. The prevention and control of Legionella spp. Equipment and factories of poor hygienic design are difficult to clean.
Safe storage and distribution of water in food factories. As food safety does not end at the borders of Europe, the EHEDG actively promotes global harmonization of guidelines and standards.
Continuous UHT Sterilization of Liquid Food Buy Buy Buy Buy Second Edition, May – Sterilization is a heat treatment aimed at destroying all vegetative microorganisms and spores to create a product which can be stored at ambient temperature yet minimizing public health hazard. Upon delivery, a packing machine needs to be checked by a commissioning procedure to be agreed in advance between the food processor and the supplier. The guidelines apply to all valves used in contact with food or food constituents that are to be processed hygienically or aseptically.
Challenge tests for the evaluation of the hygienic characteristics of packing machines for liquid and semi-liquid products. After documents 3 and 11this is the third test method in the series.
Gaskets of various types were tested for reliability guidelinew hygienic aspects using EHEDG cleanability test methods and repeated sterilisation. This document describes the requirements particularly for liquid foods without particulates. Safe and hygienic water treatment in food factories.
Buy Buy Buy Buy Buy. To validate the bacterial retention ability of sterilising grade hydrophobic membrane filters, a bacterial aerosol challenge test methodology was developed. Appropriate cleaning procedures are described, dry cleaning being favoured to reduce risks of contamination.
Microbiologically safe continuous pasteurisation of liquid foodsid soil to drop or to be drawn into the main product or container. These guidelines are intended to assist food producers in the design, guodelines, installation, and operation of air handling systems.
