Akwai hanyoyi da yawa don shirya alkyl polyglycosides ko alkyl polyglucosides gaurayawan. Hanyoyi daban-daban na roba sun bambanta daga hanyoyin stereotactic roba ta amfani da ƙungiyoyin kariya (yin mahadi masu zaɓe sosai) zuwa hanyoyin da ba zaɓaɓɓu ba (haɗuwa isomers tare da oligomers).
Duk wani tsari na masana'antu da ya dace don amfani akan sikelin masana'antu dole ne ya cika ka'idoji da yawa. Yana da mahimmanci don samar da samfurori tare da kaddarorin da suka dace da tsarin tattalin arziki. Akwai wasu fannoni, kamar rage illa ko sharar gida da hayaki.

1. Raw kayan don samar da alkyl polyglycosides
1.1 Barasa mai Fat
Ana iya samun barasa mai kitse daga kayan abinci na petrochemical (synthetic fatty alcohols) ko daga na halitta, albarkatun da ake sabunta su kamar kitse da mai (alcohols fatty na halitta). Ana amfani da cakuda barasa mai kitse a cikin haɗin alkyl glycosides don kafa ɓangaren hydrophobic na kwayoyin. An samo barasa mai kitse na halitta ta hanyar transesteration da rabuwa da mai da mai (triglyceride) don samar da daidaitaccen fatty acid methyl ester, da hydrogenated. Dangane da tsawon sarkar alkyl mai kitse da ake buƙata, manyan abubuwan da ake buƙata sune mai da mai: kwakwa ko man kernel don jerin C12-14, da tallow, dabino ko mai rapeseed ga C16-18 fatty alcohols.
1.2 Carbohydrate tushen
Sashin hydrophilic na alkyl polyglycoside molecule an samo shi daga carbohydrate.
Macromolecular carbohydrates da monomer carbohydrates dogara ne a kan sitaci na
masara, alkama ko dankalin turawa kuma ana iya amfani dashi azaman albarkatun ƙasa don shirye-shiryen alkyl glycosides. Misali, ƙwayoyin carbohydrates na polymer sun haɗa da ƙananan ƙananan matakan sitaci ko glucose syrup, yayin da carbohydrates monomer zasu iya zama kowane nau'i na glucose, kamar su glucose mai ƙarancin ruwa, glucose monohydrate, ko mafi ƙasƙanci glucose syrup.
Zaɓin ɗanyen abu yana tasiri ba kawai farashin albarkatun ƙasa ba, har ma da farashin samarwa.
Gabaɗaya magana, farashin albarkatun ƙasa yana ƙaruwa cikin tsari sitaci/glucose syrup/glucose monohydrate/glucose mara ruwa yayin da buƙatun kayan aikin shuka kuma don haka farashin samarwa ya ragu cikin tsari iri ɗaya. (Hoto na 1)
