Description
Etaballas jematerial. Etaballa's material.
Ved varmesterilisering av eggehviteholdige næringsmidler, spesielt fisk, kjott og visse gronnsaker, oppstår det svovelforbindelser som frembringer farvinger på innsiden av hvitblikkbokser. Disse farvinger bar ingen innflytelse på smak og holdbarhet av nærings-midlet. I bokser av aluminium reagerer svovelforbindelsene ikke med innsiden av boksveggen. Forbindelsene forblir i boks-innholdet og kan påvirke dets smak og lukt. When heat sterilizing foodstuffs containing egg whites, especially fish, meat and certain vegetables, sulfur compounds are produced which cause discoloration on the inside of tin cans. These colorings had no influence on the taste and durability of the food. In aluminum cans, the sulfur compounds do not react with the inside of the can wall. The compounds remain in the box contents and can affect its taste and smell.
Foreliggende oppfinnelse overvinner denne ulempe ved aluminium-emballasje. Oppfinnelsen går ut på et emballasjernaterial for eggehviteholdige næringsmidler, bestående av aluminiumfolie som på innsiden er kasjert med en kunststoffolie, hvilket næringsmiddel i emballasjen underkastes en varmesterilisering, og det særegne består i at kunststoffolien inneholder et pigment som absorberer svovelforbindelser som oppstår under varmesteriliseringen. The present invention overcomes this disadvantage of aluminum packaging. The invention concerns a packaging material for foodstuffs containing egg white, consisting of aluminum foil which is lined on the inside with a plastic foil, which foodstuff in the packaging is subjected to heat sterilization, and the peculiarity is that the plastic foil contains a pigment that absorbs sulfur compounds that arise during the heat sterilization.
Som pigment for absorbering av svovelforbindelsene blir det i forste rekke tale om sinkoksyd, som fortrinnsvis inneholdes i kunst-stoff olien i en mengde på 0,5 - 3%- Kunststoffolien, kasjert med aluminiumfolien, består fortrinnsvis av et polyolefin, f.eks. polyetylen eller polypropylen, og kan ved hjelp av kjente metoder, f.eka ved hjelp av et klebemiddel, forbindes med aluminiumfolien. The pigment for absorbing the sulfur compounds is primarily zinc oxide, which is preferably contained in the plastic oil in an amount of 0.5 - 3%. The plastic foil, lined with the aluminum foil, preferably consists of a polyolefin, e.g. polyethylene or polypropylene, and can be connected to the aluminum foil using known methods, e.g. using an adhesive.
Ved varmesteriliseringen oppstår det som folge av nedbryting av proteiner forbindelse med sulfhydrilgrupper og med svovelvannstoff. Disse forbindelser absorberes av sinkoksydet i kunststoffolien During the heat sterilization, as a result of the breakdown of proteins, compounds with sulfhydryl groups and with hydrogen sulphide occur. These compounds are absorbed by the zinc oxide in the plastic film
slik at de ikke lenger kan utvirke uheldig på emballasjeinnholdets smak. Emballasjenraterialet i henhold til oppfinnelsen er derfor spesielt egnet for eggehviteholdige næringsmidler. Emballasjen kan være i form av poser eller bokser. so that they can no longer have an adverse effect on the taste of the packaging contents. The packaging material according to the invention is therefore particularly suitable for foodstuffs containing egg white. The packaging can be in the form of bags or boxes.
Spesielt egnet er emballasjenraterialet i henhold til oppfinnelsen for emballering og sterilisering av sardiner i såkalte lettbeholdere, som består av dyptrukne bokser av aluminiumbånd kasjert med en polyolefinfolie og med en tykkelse på 0,06 til 0,2 mm og med et lokk av tilsvarende material, hvor ]okket er forseglet til en utad ombukket kantflens på boksen. The packaging material according to the invention is particularly suitable for packaging and sterilizing sardines in so-called lightweight containers, which consist of deep-drawn cans of aluminum strips lined with a polyolefin foil and with a thickness of 0.06 to 0.2 mm and with a lid of similar material, where the ]ock is sealed to an outwardly bent edge flange on the box.
Av sunnhetsmessige betraktninger bor det pigment som benyttes helst ikke vandre fra kunststoffolien til det emballerte næringsmiddel. Undersøkelser har vist at det i dette henseende er spesielt egnet med folier som består av polyetylen som er tilsatt akrylsyre. Ved behandling av disse folier, som inneholder \% ZnO, i olivenolje i 80 min. ved 115° lar det seg selv ved finere analytiske metoder ikke påvise noen overgang av sink til olivenoljen, mens det ved vanlig polyetylen utloses små menger ZnO, som imidlertid er mindre enn de mengder sink som allerede er tilstede i olivenoljen. For reasons of health, the pigment used should preferably not migrate from the plastic film to the packaged foodstuff. Investigations have shown that, in this respect, foils consisting of polyethylene to which acrylic acid has been added are particularly suitable. When treating these foils, which contain \% ZnO, in olive oil for 80 min. at 115°, even with finer analytical methods it is not possible to detect any transfer of zinc to the olive oil, while with ordinary polyethylene, small amounts of ZnO are released, which are, however, smaller than the amounts of zinc already present in the olive oil.
