[article]  inPAINTINDIA > N° Annuel 2003 (2003) . - p. 99-108 Titre : Hygienic coatings in the food industry environment: The Italian standard Type de document : texte imprimé Auteurs : C. Pagella, Auteur ; D. Fumi, Auteur ; R. Galli, Auteur ; D. M. De Faveri, Auteur Année de publication : 2003 Article en page(s) : p. 99-108 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The mandatory introduction of HACCP assessment in food industries has drawn attention to all topics connected with the safety of food, including those related to the coatings applied in places where food is manufactured, preserved, packed and consumed. The authors had formerly pointed out the need for a test protocol for paints and coatings to be used in environments where food is present. They also implemented the protocol and tested several paints currently available in the Italian marketplace. The experience gained helped in development of an industry standard which is now published as UNI 11021. An outline of the standard and related experimental results are presented in this paper. Existing regulations and standard test methods have been used or adapted for controlling hazardous substances and assess general properties such as dirt pick-up, hiding power, wet scrub resistance or resistance to chemicals and cleaning agents. New specific test methods have been developed for cleanability, release of odours, mildew growth resistance. Cleanability is the attitude of a coating to be cleaned using mechanical action and detergents. Film porosity and gloss, PVC and pigment/binder ratio can affect cleanability. Paint films were coated with a standard dirt, then washed using a plynometer for 50 strokes. The colour difference (cleaned/not dirty) was measured using a spectrophotometer. Tests for release of odours were carried out exposing two simulants (fresh water - Philadelphia cheese) in the presence of the coating in a gas-tight chamber. Coating surface to chamber volume ratio was 3 m-1. The samples were then tested for organoleptic alterations by persons informed of the scope of the test and trained. Tests for mildew growth resistance were carried out after sampling naturally occurring strains from wall coatings in northern Italy. 50 strains were isolated, belonging mainly to Aspergillus, Penicillium, Alternaria, Paecilomyces, Fusarium species. Proper strains were selected as standard testing strains. The paint was applied on different supporting materials, properly dried and placed onto Petri dishes with malt agar or water and innoculated with suspended spores. Some specimens were previously washed to assess the effect of biocides leaching. After incubation samples were rated for growth occurring.

Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Building materials such as masonry, plaster and their rendering change over the years. They undergo degradation due to phenomena associated with the materials used in their preparation and environmental conditions (chemical agents, acid rain, pollution and changing weather). Water is one of the most important agents involved in degradation. In addition to acting as a carrier for salts and other chemicals, it produces phenomena such a condensation, freeze-thaw cycles rain, etc. Water soaks into walls through many different routes.

Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The UNI 11021 standard, to assess the characteristics of coatings in a food manufacturing or distribution environment, has recently been issued. Is is hoped that it will serve as a reference to regulators aiming at the application of the "hazard analysis critical control point" (HACCP) safety control scheme in the food sector, and give the marketplace a clear pattern of requirements for coating specifications.
