The influence of different cooling techniques (dry ice/ice packs) and storage temperature (-2°C/3°C) to prolong the shelf life of Arctic charr (Salvelinus alpinus) fillets were evaluated by sensory analysis, physical methods, chemical and microbial analysis. The effects of storage temperature were stronger than of different cooling agents. Superchilling (-2°C) of fillets packed with dry ice resulted in 6 days extension of shelf life compared to chilling (3°C). The use of dry ice parallel to superchilling prolonged shelf life for 1 day compared to fillets stored with ice packs. No negative effects on quality of the fillets where detected that could be linked to cell destruction caused by partial freezing or to sour taste, caused by absorption of CO2 gas in fish flesh.

In an accelerated storage test at 60 °C. fat levels of 20 and 30% were observed to have no effect on keeping quality of dehydrated pork. Measurements on dried product stored in paper-bodied containers for one year at temperatures from −17.8 °C. to 36.7 °C. showed 15.6 °C. to be less desirable than 23.9°, 0°, or −17.8 °C. Dehydrated pork was stored in tin-plate containers for periods of one year at 23.9 °C. and 36.7 °C. with little decrease in palatability. No difference in storage life was demonstrated between cured and uncured pork, or, as a result of differences in drying times, moisture content |or storage temperature. The product prepared on an atmospheric double-drum drier deteriorated a little more rapidly than vacuum–tray- or tunnel–tray-dried material. The effectiveness of container materials, tin-plate, Reynolds' metal A-10, Dewey and Almy P-16, and 300 MST cellophane, was evaluated and their relative value for dehydrated pork fell in that order.

Irish moss (Chondrus crispus) from Canada's east coast was used to study possible improvements in the production and storage of gelose. The optimum pH for the extraction of gelose from Irish moss was between 6 and 7. Fine leaf particles, which prevent rapid filtration, were readily removed by supercentrifuging. Comparison of drum drying and drying from the frozen state showed that the former caused a marked lowering of viscosity but had little effect on suspending power or jelly strength. The logarithm of the viscosity determined by means of a MacMichael viscosimeter was related directly to the concentration; therefore, viscosity measurements can be corrected for the moisture content of the samples. The effect of storage temperature on deterioration was greater than the effect of relative humidity. Samples stored at 0° and 40° F. for 12 weeks showed no significant changes in viscosity or suspending power, whereas those stored at 80° and 120° F. deteriorated very rapidly. Material was vacuum ice-dried to 2% moisture without damage but the quality decreased when the extracts were stored at high temperatures.
