How does different indigenous yeast strains influence the aroma development and taste during fermentation of apple juice? (English)
Abstract [sv]

Intresset för lokalproducerad dryck ökar. Konsumenten efterfrågar produkter med mer komplexa smaker. Främst gäller detta produktkategorin öl, vin och cider. Det har i flera studier visats att lokala stammar av mikroorganismer kan användas för att tillverka produkter med en större smakkomplexitet än de produkter som baseras på konventionella stammar. Detta har fått bryggare och vinmakare att experimentera med såväl val av råvara som mikroorganismer i syfte att ta fram unika produkter. I denna studie har tre lokala stammar av Saccharomyces cerevisiae undersökts avseende eventuella skillnader i fermenteringsförlopp och aromutveckling samt smak vid fermentering av äppeljuice. Resultatet från studien visar att alla stammarna överlag beter sig lika inklusive enskilda sensoriska attribut och att en fermentering på tre dagar ger upphov till högre totalt gillande av produkt än vid sju dagars fermentering.

Abstract [en]

There is an increasing interest in locally produced drinks. Consumers demand products with complex taste profiles. Especially when it comes to wine, beer and cider. Several studies have shown that indigenous strains of microorganisms can be used to produce products that’s deemed more complex than the products based on conventional strains. This has led brewers and winemakers to experiment with both the raw material as well as the local microorganisms in order to develop unique products. In this study, three local strains of Saccharomyces cerevisiae have been studied for potential differences regarding aroma development and taste during fermentation of apple juice. The results from the study showed that the different strains generally behaved the same, and that fermentation during three days resulted in greater taste liking compared to seven days.
