Cie\u013eom spolo\u010dnosti Cell Instruments Co., Ltd. je poskytova\u0165 vedecky podlo\u017een\u00e9 met\u00f3dy hodnotenia text\u00fary ob\u010derstvenia. Cie\u013eom tohto testu text\u00fary zemiakov\u00fdch lupienkov bolo stanovi\u0165 opakovate\u013en\u00e9 krit\u00e9rium na meranie tvrdosti lupienkov v r\u00f4znych \u0161ar\u017eiach a typoch lupienkov.

Pri experimente sa pou\u017eil softv\u00e9rovo riaden\u00fd analyz\u00e1tor text\u00fary potrav\u00edn (napr. Cell Instruments\u2019 TMS-PRO) vybaven\u00fd sn\u00edma\u010dom za\u0165a\u017eenia 1000 N a 100 mm plochou kompresnou doskou. Na ulo\u017eenie objemovej vzorky zemiakov\u00fdch lupienkov sa pou\u017eil vysok\u00fd plastov\u00fd valec (priemer 125 mm a v\u00fd\u0161ka 165 mm). Namiesto testovania jednotliv\u00fdch chipsov sa metodika spolieha na sk\u00fa\u0161ku objemov\u00e9ho stla\u010denia ob\u010derstvenia, aby sa simulovali viacer\u00e9 \u017euvacie \u010dinnosti v re\u00e1lnom scen\u00e1ri konzum\u00e1cie.<\/p>\n\n\n\n
Ka\u017ed\u00e1 sk\u00fa\u0161obn\u00e1 sekvencia pozost\u00e1vala zo \u0161tyroch po sebe nasleduj\u00facich stla\u010den\u00ed v r\u00f4znych h\u013abkach: 120 mm, 100 mm, 80 mm a 60 mm od z\u00e1kladne n\u00e1doby. Po ka\u017edom stla\u010den\u00ed sa syst\u00e9m stiahol o 10 mm, aby sa napodobnila relaxa\u010dn\u00e1 f\u00e1za medzi z\u00e1kusmi. R\u00fdchlos\u0165 stl\u00e1\u010dania bola nastaven\u00e1 na 1000 mm\/min, aby sa proces \u0161tandardizoval.<\/p>\n\n\n\n
Syst\u00e9m potom pomocou softv\u00e9ru Texture Lab Pro vypo\u010d\u00edtal energiu - alebo \u201cpr\u00e1cu\u201d - potrebn\u00fa na stla\u010denie objemovej vzorky po\u010das v\u0161etk\u00fdch \u0161tyroch cyklov.<\/p>\n\n\n\n
Grafick\u00e9 v\u00fdsledky testu text\u00fary zemiakov\u00fdch lupienkov jasne uk\u00e1zali n\u00e1rast sily potrebnej pri ka\u017edej nasleduj\u00facej \u00farovni stla\u010denia. Najm\u00e4 posledn\u00fd cyklus poskytol najjasnej\u0161ie rozl\u00ed\u0161enie medzi be\u017en\u00fdmi \u010dipsami a variantmi v tvare kotl\u00edka.<\/p>\n\n\n\n
Napr\u00edklad vzorka Z (kotl\u00edkov\u00e1 dr\u0165) potrebovala na stla\u010denie viac ako 25% energie ako vzorka Y, \u010do potvrdzuje, \u017ee vzorka Z mala v\u00fdrazne tvrd\u0161iu \u0161trukt\u00faru. Vysok\u00e9 hodnoty hodnotenia tvrdosti zemiakov\u00fdch lupienkov sa zhodovali so senzorick\u00fdmi o\u010dak\u00e1vaniami, \u010do potvrdzuje spo\u013eahlivos\u0165 met\u00f3dy.<\/p>\n\n\n\n
Hoci rozdiely vo ve\u013ekosti, tvare a \u0161trukt\u00fare \u010dipov viedli k vy\u0161\u0161\u00edm \u0161tandardn\u00fdm odch\u00fdlkam, pou\u017eitie met\u00f3dy hromadn\u00e9ho testovania pomohlo spriemerova\u0165 nepravidelnosti a zabezpe\u010dilo reprezentat\u00edvnej\u0161iu anal\u00fdzu.<\/p>\n\n\n\n
Test objemovej kompresie pre ob\u010derstvenie sa uk\u00e1zal ako \u00fa\u010dinn\u00fd pri rozli\u0161ovan\u00ed text\u00farnych rozdielov medzi odrodami zemiakov\u00fdch lupienkov. Prin\u00e1\u0161a:<\/p>\n\n\n\n

Introduction Evaluating the texture of potato chips has traditionally relied on sensory testing, which, while valuable, often lacks consistency and objectivity. In an effort to provide a more reliable method, a potato chip texture test was developed using a computer-controlled texture analyzer for food.
