Expandability of Acheta domesticus : A study on the effect of cricket flour on color, texture, liking and expansion in extruded corn puffs. (English)
Abstract [sv]

I takt med en ökande världspopulation ställs allt hårdare krav på primärproducenter att tillgodose råvaror i adekvata mängder. Forskning inom området är av stor vikt för att hitta nya hållbara källor för näringsämnen som exempelvis protein, eftersom produktionen i dagsläget för med sig många miljömässiga nackdelar. I samband med att EU godkänner insekter som livsmedel får fler upp ögonen för eventuella fördelar som de kan bidra med som råvara. Syftet med denna studien är att undersöka vilken påverkan tillsats av syrsmjöl har på färg, textur, gillande och expansion hos extruderad majskrok. Detta är ett steg i riktningen mot implementering av insekter i västerländsk kost. Genom att analysera vatten och proteinhalt i den extruderade produkten, samt mäta dess färg, textur, radiella expansion och gillande hos konsument kan insamlad data ställas mot varandra och eventuella korrelationer belysas. Resultatet från studien visar att vid högre andel syrsmjöl blir texturen kompaktare, expansionen mindre och en färgförändring sker åt det mörkare hållet. De prov med lägre andel tillsatt syrsmjöl, och därmed en bättre expansion, fick högst gillandepoäng på alla frågeställningar i ett konsumenttest.

Abstract [en]

In line with a growing world population, higher demands are put on primary producers to supply raw materials in adequate quantities. Research in the area is of great importance in finding new sustainable sources of nutrients such as protein, which presently brings with it many environmental disadvantages. As the EU approves insects as food, more people are becoming aware of potential benefits they can provide. The purpose of this report is to investigate the effect of the addition of cricket flour on the color, texture, liking and expansion of an extruded corn puff. This is a step towards the implementation of insects in the Western diet. By analyzing the water and protein content of the extruded product, as well as measuring its color, texture, radial expansion and consumer appreciation, collected data can be compared and any correlations can be shown. The results of the study show that with a higher proportion of cricket flour the texture becomes more compact, shows less expansion and a color change toward a darker tone. The samples with a lower proportion of added cricket flour, and thus a better expansion, received the highest points of liking on all the questions in the consumer test.
