TW577812B - Molecular sieve containing structure for organoleptic scavenging - Google Patents

Abstract

An organoleptic paperboard packaging structure using a molecular sieve powder to adsorb low molecular weight oxidation products formed during the extrusion coating process. Off tastes and odors that develop as product degrades and ink off-odors are also removed by the molecular sieve powder incorporated in the product contact layer during extrusion.

Description of the invention (Fenming background 1_ · (Please read the precautions on the back first and then fill in the book to buy) Absorbents (such as molecular sieves (ecolites), clay, oxidized sand and diatomaceous earth) In addition to low-molecular-weight oxidation products formed during processing (such as extrusion coating of polyassociated hydrocarbons); removal of tastes and odors generated by the decomposition of the product structure (such as brewed from lipid oxidation or produced from protein degradation) Thioethers); and removing ink and / or varnish odors transferred from glass to matte during storage in drum or slab form. Manufacturers of cereals, fruit juices and the like complain that The cardboard-based gable top box has a polymer odor and taste. More specifically, these odors and tastes have been called "plastic-like." The product contact layer of the substrate is 'such as low-density, high-density polyethylene. The odor and flavor (flavor) to be removed have been identified as low-molecular-weight volatile oxidation products such as hexanal. In addition,' contained in the package The odor and taste produced by the decomposition of the food products in the box is also a problem. The oxidation of lipids in cereals will form hexanal and make the cereals have a distinct odor. Third, the combination is from the printed substrate. The undesired odor caused has also been identified as a post. Finally, printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, the removal of unwanted compounds in the product that are not generated by the product decomposition but are not known is also a problem. Examples thereof include water with flavor compounds removed or water containing by-product compounds from packaging or refining. Several existing patents have discussed the incorporation of zeolite molecular sieves into plastic materials to remove them that are produced during the manufacture of plastic materials.
