There is interest in storing low-moisture foods for long periods of time for uses such as personal preparedness, disaster relief efforts and space travel. Pinto beans in restaurant-sized No. 10 cans are available in the retail market, but work is needed to determine the effects of long-term storage on quality. The objective of this research was to investigate the quality of retail-packaged pinto beans held at ambient temperatures up to 32 years. Fifteen samples of pinto beans packaged in No. 10 cans, which were treated to remove oxygen, were obtained from donors. Samples ranged from <1 to 32 years in age. Prior to cooking, pinto bean samples were soaked in water containing varying levels of baking soda to standardize textural attributes.

There is interest in the long-term storage of low-moisture foods for applications such as space flight, disaster relief, and personal preparedness. Wheat packaged in restaurant-size No. 10 cans has been available in the retail market for decades. However, the quality of such wheat held in long-term storage is not well characterized. The purpose of this research was to examine the effects of long-term storage on the quality of wheat packaged in No. 10 cans and held at ambient temperatures up to 32 years. Twenty samples of hard red wheat (including 4 duplicates) packaged in No. 10 cans were obtained from …

We assessed the effects of prolonged reduction of plasma retinol concentrations (hyporetinolemia) on the distribution of tissue vitamin A (VA) and of its active compounds using a model of continuous recombinant human interleukin-6 (rhIL-6) infusion via osmotic minipumps in VA-sufficient male rats. Plasma retinol and retinol-binding protein (RBP) concentrations remained decreased and lower in rhIL-6-treated rats compared with controls from 7.5 h throughout 7 days of infusion (P < 0.001). This reduction was accompanied by a 68% increase in hepatic retinol concentration by 7 days (P < 0.05). Hepatic and renal retinyl palmitate and retinoic acid concentrations did not change, and renal megalin content remained unchanged; hepatic RBP concentrations were 41% lower in rhIL-6-treated rats compared with controls (P < 0.05). These results indicate that instead of being lost, retinol accumulated in the liver during inflammation and that hyporetinolemia was attributable to a decrease in the availability of hepatic RBP. A plausible consequence of the effect of rhIL-6-induced hyporetinolemia is that by 7 days tissues that are dependent on plasma retinol may become deprived of VA.These results have important implications in understanding the mechanism by which measles infection induces hyporetinolemia and VA deficiency of extrahepatic tissues.
