Effect of Oak Seed Pretreatment with Sensory Evaluation of Acorn Flour

Abstract

Seeds of oak used as a famine food formerly. Pre-treatment of the oak acorn (Quercus robur) was performed using different methods (roasting in ash, freezing, baking, boiling) to reduce the tannin content in the seed. After baking ground acorns were evaluated by sensory testing with 32 testers. The worst values were in case of ash-treated seeds. This result was also supported by statistical data in case of three parameters (colour, hardness, moisture). There is no significant difference in the other two parameters (fragrance, aftertaste). There was no difference among the treatments between the sexes, age and educational qualification of the judges.
