Antioxidant properties and sensory profiles of breads containing barley flour.

Breads were made by replacing 40% of wheat flour with barley flour. The incorporation of barley increased the antioxidant properties of the breads compared to the control bread. Furthermore, these properties proved to be dependent on the variety of barley as well as the extraction rate of the flour.

Active photosensitizers in butter detected by fluorescence spectroscopy and multivariate curve resolution.

In this study, fluorescence excitation and emission matrices and multivariate curve resolution (PARAFAC) were used to detect and characterize active photosensitizers spectrally in butter. Butter samples were packed under high (air) and low oxygen (<0.05%) atmospheres and exposed to violet, green, or red light.

Functional properties of pre-rigor, pre-salted ground beef chilled with solid carbon dioxide.

Ground, pre-salted, pre-rigor semimembranosus muscles of beef were subjected to three treatments A=rapid carbon dioxide (CO(2)) chilling, B=slow CO(2) chilling and C=air chilling, and compared to a control D=slow air chilling of muscles, which were subsequently ground and salted post-rigor. Meat of the pre-rigor treatments A, B and C had higher pH values during processing, lower cooking loss, firmer texture and a lighter yellowish external colour of cooked patties than the post-rigor control D (p<0.05).

A sensory map of the meat universe. Sensory profile of meat from 15 species.

The aim of the study was to investigate if meat from different species could be described and related to each other by sensory analysis. Muscle meat from 15 different species commercially available in Norway was assessed by a 22 sensory attribute profile and analysed by multivariate analysis. The different species were significantly different on attributes that gave adequate descriptions of all species.
