Sensory analysis was performed on fresh fruits, frozen non-cooked jam and traditionally cooked jam of 14 strawberry cultivars. The purpose was to characterise and compare the sensory quality of different strawberry cultivars and different types of jam. The results of the investigation were presented by means of multivariate modelling methods such as principal component analysis (PCA) and partial least squares regression (PLS). The sensory profile of cooked jam differed from that of fresh fruits and frozen jam, explaining 75% of the total variation in the first component. Cooked jam scored high for sweet taste, stickiness, bitter taste, earthy flavour, off-flavour and total intensity of taste. Frozen jam had many of the same sensory characteristics as fresh fruits and scored high for strawberry flavour, fruity flavour and whiteness, while fresh fruits scored highest for colour strength, hue and sour taste. As analysed by means of PLS, sensory colour and flavour variables of fresh fruits were able to predict 35% of sensory cooked jam variables. Analysing early cultivars alone, sensory fresh fruit variables were able to predict 69% of sensory cooked jam variables. (C) 2000 Society of Chemical Industry.

The effect of six cropping systems (rotations of either mainly arable or mainly forage crops) on the soil N content was evaluated using mass balances of total N, and the usefulness of such N balances to predict N runoff (total N losses via drainage and surface water) was investigated. All the arable cropping systems resulted in a net reduction in the calculated soil N pool, and the reduction increased with decreasing N input. Only the forage system with the highest N input maintained the initial soil N content. Mass N balances were found to be a useful tool for predicting N runoff, as up to 87% of the variation in N runoff could be explained.

A computer model for long-term forest management analysis is described. It is a deterministic simulation model, and provides means for a range of possible analyses; different management strategies, i.e. harvest- and silvicultural investment strategies, along with the corresponding cash flow, development of forest state and profitability. The description is accompanied by a case study, employing some features of the model, based on data covering Hedmark county in Norway, with the objective of mapping consequences for potential harvest level and net present value related to varying treatments for different border zone types.
