Kostfiber avskiljs därefter genom filtrering av pro- vet genom glasfilter. Härvid förloras uppenbarligen vat- tenlösliga kostfiberkomponenter, varför samtliga ovan angivna metoder ger kostfibervärden som endast innefat- tar icke vattenlösliga komponenter.Dietary fiber is then separated by filtering the sample through a glass filter. In this case, water-soluble dietary fiber components are obviously lost, which is why all the above methods give dietary fiber values that only include non-water-soluble components.

Tecator AB, Höganäs, har sedan 1976 marknadsfört en apparat - FIBERTEC - (jfr svensk utläggningsskrift 7611015-4) för analys av kostfiber med râfibermetoden eller “neutral detergent fiber/acid detergent fiber"-me- toden. Apparaten rationaliserar kostfiberanalys med des- sa metoder, men utnyttjar liksom originalmetoderna filt- rering genom glasfilter för avskiljning av kostfiber.Tecator AB, Höganäs, has been marketing an apparatus since 1976 - FIBERTEC - (cf. Swedish Offenlegungsschrift 7611015-4) for analysis of dietary fiber with the crude fiber method or the "neutral detergent fiber / acid detergent fiber" method. methods, but uses, like the original methods, filtration through glass filters to separate dietary fiber.

Ej heller denna apparat bestämmer sålunda vattenlösliga fiberkomponenter.Nor does this apparatus thus determine water-soluble fiber components.

Uppfinningens ändamål är att åstadkomma ett sätt och en anordning som medger bestämning av såväl vattenolös- liga som vattenlösliga växtfiberkomponenter, särskilt kostfiberkomponenter i växtmaterial.The object of the invention is to provide a method and a device which allows the determination of both water-insoluble and water-soluble plant fiber components, in particular dietary fiber components in plant material.

Detta uppnås enligt uppfinningen medelst ett sätt och en anordning, som har de i patentkraven angivna kän- netecknen.This is achieved according to the invention by means of a method and a device which have the features stated in the claims.

Uppfinningen beskrivs i det följande närmare med etta utföringsexempel och under hänvisning till bifogad rit- ning, som visar en anordning enligt uppfinningen i schematiskt snitt.The invention is described in more detail below with one exemplary embodiment and with reference to the accompanying drawing, which shows a device according to the invention in schematic section.

Provet, som skall analyseras med avseende på såväl vattenolösliga som vattenlösliga komponenter förbehand- las (eventuellt efter fettextraktion) genom inkubation med enzymer, som har förmåga att nedbryta protein och stärkelse i provet till sådana små fragment, som kan pas- sera genom ett ultrafilter l. Därpå filtreras det enligt ovan med avseende på protein och stärkelse solubilisera- de och nedbrutna provet genom ett glasfilter 2 och ett ultrafilter l, som uppstödes av en hållare 3.The sample to be analyzed for both water-insoluble and water-soluble components is pretreated (possibly after fat extraction) by incubation with enzymes capable of degrading protein and starch in the sample into such small fragments which can pass through an ultrafilter. Then, as above, with respect to protein and starch, the solubilized and degraded sample is filtered through a glass filter 2 and an ultrafilter 1 supported by a holder 3.

I det visade utföringsexemplet utföres filtreringen 1 ett steg genom en kombination av glasfiltor 2 och ult- 7710720-9 _10 .FS rafilter l, men filtreringen kan alternativt utföras i två steg, genom att först filtrera ursprungsprovet ge- nom flasfiltret 2 och sedan filtrera det erhållna filtra-- tet genom ultrafiltret l. I båda fallen kan filtreringen drivas genom antingen övertryck före eller vakuum efter filtrerna 1 och 2.In the exemplary embodiment shown, the filtration 1 is performed one step through a combination of glass filters 2 and ultimate filter 1, but the filtration can alternatively be performed in two steps, by first filtering the original sample through the bottle filter 2 and then filtering it. the filtrate obtained by the ultrafilter 1. In both cases the filtration can be driven by either overpressure before or vacuum after filters 1 and 2.

För analys av kostfiberkomponenter torkas och vägs det kostfibermaterial som avskiljts genom filtreringen av filtrerna 1 och 2. Det material som avskiljts av glas- filtret 1 resp ultrafiltret 2 kan därvid antingen vägas 'tillsammans (total kostfiber) eller var för sig (icke vattenlöslig resp vattenlöslig kostfiber).For analysis of dietary fiber components, the dietary fiber material separated by the filtration of filters 1 and 2 is dried and weighed. The material separated by the glass filter 1 and the ultrafilter 2 can then be weighed either together (total dietary fiber) or separately (non-water-soluble or water-soluble dietary fiber).
