The role of normative information, task difficulty and goal commitment on task performance in an assigned goal condition was investigated in a laboratory study using 209 student volunteers. The experiment was a 2 (task difficulty) by 2 (normative inf

SummaryMultiple regression analysis has been used to relate contributions of individual flavour components to the flavour of Cheddar cheese. Equations have been derived that relate Cheddar flavour to the headspace concentrations of 2-pentanone, metha

SUMMARYCheesemaking is initiated by specific hydrolysis of κ-casein, followed by random aggregation of casein particles to form a network. The structure of this curd determines its subsequent behaviour and the composition and texture of the cheese.

SUMMARYBlocks of Cheddar cheese ranging in weight from ¾ to 44 lb were vacuum-wrapped and stored for up to 6 weeks. Panel assessment after 0, 3 and 6 weeks showed that the quality decreased, and off-flavours increased with decrease in block size. He

SummaryA method is described for the chromatographic analysis of the headspace of hard cheese. Among the cheeses examined were 12 commercial cheeses and 12 Cheddars made in the NIRD experimental dairy. The 12 commercial cheeses were Parmesan, Caerphi

SummaryCheddar cheeses were pressed from a batch of curd each month over a period of 1 year to study the production of headspace volatiles and the development of flavour in ripening cheese. At 2-monthly intervals, samples taken from selected sites in

SummaryThe effect of heat treatment of milk on low molecular weight, volatile compounds was studied in order to relate changes in the flavour of milks to changes in chemical composition. Milks were heat treated in a UHT plant for 3 or 90 s at 140 °C

SUMMARYMilks from two groups of dairy cows grazing either white clover or ryegrass swards were compared to determine whether their acceptability in terms of flavour, composition and rennet coagulation properties was affected by these differences in t

SummaryPossible mechanisms for the production of volatile sulphur compounds during the ripening of Cheddar cheese have been studied. Slurries of cheese made with and without starter organisms were treated with dithiothreitol (DTT) and the chemical co
