Explaining and predicting individually experienced liking of berry fractions by the hTAS2R38 taste receptor genotype

Consumption of lingonberries by TAS2R38 genotype and sensory quality of texture-designed lingonberry samples

“…Previous studies have shown that one's TAS2R38 genotype affects one's preference for polyphenol-rich berry fractions (bilberry and crowberry samples), as PAV homozygotes like such extracts less than AVI homozygotes do (Laaksonen et al, 2013). Among children, it has also been observed that liking scores for berry products differ between TAS2R38 genotypes, although there was no difference in the usual consumption of all berries as reported by the parents (Suomela et al, 2012).…”

“…Interestingly, the berry skin matrix in the pulp was shown to decrease astringency, but all of the other properties of flavor profile remained stable compared to the juice. From this point of view, lingonberries are different from crowberries and bilberries (Laaksonen et al, 2013).…”

“…DNA samples were collected with cheek swabs and genotyping of TAS2R38 was performed as previously described in detail (Laaksonen, Ahola, & Sandell, 2013). There were 16 PAV/PAV homozygotes, 35 PAV/AVI heterozygotes and 32 AVI/AVI homozygotes.…”

Two complementary methods for genotyping taste receptor TAS2R38 in humans

“…Culture differences, age, desired healthiness and mood can all affect taste perception. There has been increasing interest in PTC sensitivity and the impact on dietary choices (Bufe et al, 2005;Drewnowski et al, 2001;Laaksonen et al, 2013;Sandell & Breslin, 2006). In an interesting twist, there is evidence suggesting that berries from the plant Antidesma busnius found in Southeast Asia and northern Australia are bitter to PTC non-tasters and sweet to tasters (Henkin & Gillis, 1977;Tharp et al, 2005).…”

“…The rest of the foods have been placed on the list based on reports that some tasters find the food bitter and/or due to the known presence of thiourea containing substances within these foods (Drewnowski et al, 2001;Laaksonen et al, 2013;Sandell & Breslin, 2006;Wooding, 2006).…”
