The use of whole grain foods, such as oat and rye, beneficial to one's health, could be substantially extended if their flavour properties and flavour stability were better known, and they could be modified in a controlled way. The aim of this study was to specify how the flavour of oat and rye is formed, and which processing factors influence it. The understanding underlying the perceived flav...

Monovarietal virgin olive oils (VOOs) are very effective to study relationships among sensory attributes, the compounds responsible for flavour, and factors affecting them. The stimulation of the human sensory receptors by volatile and non-volatile compounds present in monovarietal virgin olive oils gives rise to the sensory attributes that describe their peculiar delicate and fragrant flavours...

Knowledge of the critical chemical compounds that are responsible for the sensory characteristics of wines is of great importance to be able to control and adjust wine flavour during wine production. Compounds not previously recognised as contributing to flavour have been identified for the first time through work in this stream, including the compound rotundone: giving Shiraz wines from many o...

Influences of shear rate (surface extension), airflow, in-mouth headspace volume, synthetic saliva and human epithelial cells (modelling mucosa) on the initial dynamic flavour release from liquids were analysed. Simulating physiological mouth parameters, initial dynamic flavour release experiments over a time period of 30 s were carried out using a proven mouth model apparatus. Flavour compound...

Rice (Oryza sativa L.) is enjoyed by many people as a staple food because of its flavour and texture. Some cultivars, like scented rice, are preferred over others due to their distinctive aroma and flavour. The volatile profile of rice has been explored by other investigators, some of whom have also determined a corresponding aroma using GC/olfactometry. However, little research has been done t...

Flavour is a key quality attribute of apples defined by volatile aroma compounds. Biosynthesis of aroma compounds involves metabolic pathways in which the main precursors are fatty and amino acids, and the main products are aldehydes, alcohols and esters. Some enzymes are crucial in the production of volatile compounds, such as lipoxygenase, alcohol dehydrogenase, and alcohol acyltransferase. C...

A method ispresentedfor determining those volatile components of Jbods that have flavour significance. The method leads to quantitative flavour specifications called charm that can be displayed graphically. The procedure is baaed upon the relative odour detection thresholds of volatile compounds of known gas chromatographic retention indices.

Roasted stem tea has a characteristic flavour, which is obtained by roasting tea stems, by-product of green tea production. The difference between roasted stem and leaf tea derived from the same tea plants were investigated using GC–MS. Pyrazine compounds exhibited a roasted odour and high flavour dilution (FD) factors, as determined via aroma extract dilution analysis (AEDA). Roasted stem tea ...

Feng J., Zhan X.-B., Zheng Z.-Y., Wang D., Zhang L.-M., Lin C.-C. (2013): New model for flavour quality evaluation of soy sauce. Czech J. Food Sci., 31: 292–305. The soy sauce samples established a model for its flavour quality evaluation. Initially, 39 types of flavour compounds, organic acids and free amino acids in six different types of soy sauce were identified and determined by HS-SPME GC...

ABSTRACT: The essential oil of plant material is the fraction isolated by means of several methods such as liquid carbon dioxide, microwaves and low or high pressure distillation employing boiling water or hot steam and is chemically defined as terpenoids namely monoterpene and the oxygenated form. Since these compounds might be employed as flavour contributors due to their chemical nature, it ...
