Summary

ATMOSPHERIC HUMIDITY MAY CAUSE CLOTTING OF THE PRODUCT, THEREFORE PACKAGES SHOULD BE WATERPROOF. LIGHT DOES NOT SEEM TO AFFECT COLOUR. THE DESTRUCTION OFASCORBIC ACID ADDED TO THE PRODUCT CAN BE CALCULATED BY MATHEMATICAL RELATIONSHIPS IF THE STORAGE TIME AND TEMPERATURE ARE KNOWN. IN ADDITION, FOR A LOSS OF 12% ASCORBIC ACID, A PANEL CAN NOTICE A DETERIORATION OF FLAVOUR. BY USING THE SAME RELATIONSHIPS, STORAGE LIFE CAN BE PREDICTED. THE PRESENCE OF OXYGEN NEAR THE PRODUCT MAY RESULT IN SOME CHANGES IN THE ORGANOLEPTIC CHARACTERISTICS EASILY NOTICED BUT NOT MARKED ENOUGH TO CAUSE A SIGNIFICANT DIFFERENCE OF FLAVOUR. QUANTITATIVE CHANGES IN AROMATIC SUB-STANCES CAN BE DETECTED BY GAS CHROMATOGRAPHY PRIOR TO INITIAL ORGANOLEPTIC DETERIORATION.
