Accelerated Storage Test

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.

Accelerated Storage Test

Background: Mefenamic acid is a non-steroidal anti-inflammatory drug (NSAID) with low solubility in water. Self-Nanoemulsifying Drug Delivery Systems (SNEDDS) play a role to improve the solubility and bioavailability of mefenamic acid. Objective: This study aimed to determine the stability of mefenamic acid in SNEDDS formulation through various stability studies. Methods: The stability studies conducted consisted of centrifugation test, heating-cooling cycle test, freezethaw cycle test, robustness to dilution, accelerated storage test, and determination of drug content. Results: The centrifugation test, heating-cooling cycle test, and freeze-thaw cycle test showed no phase separation in the samples. The robustness to dilution and accelerated storage test resulted in 2 formulas of mefenamic acid loaded SNEDDS having good stability with 10% oleic acid, 80% tween 80, 10% PEG 400 and 10% oleic acid, 70% tween 80, 20% PEG 400. The determination of drug content in both of these formulations showed 98.20 ± 0.04% and 90.98 ± 0.06%. Conclusion: The SNEDDS formulation of mefenamic acid in this study had good stability. Keywords: SNEDDS, mefenamic acid, stability study, oleic acid

Abstract Diazinon (O,O-diethyl O-(2-isopropyl-6-methyl-4-pyrimidinyl) phosphorothioate) and 3 different Diazinon formulations were analyzed both by the official CIPAC titrimetric method and by the AOAC official first action gas chromatographic method. In addition, all samples were subjected to the CIPAC accelerated storage test by heating (2 weeks at 54°C) and analyzed by the 2 methods before and after storage. Eight collaborators from European countries and the United States took part in the study. Analytical results were reproducible within and between laboratories by both methods. As demonstrated by an analysis of variance, the 2 procedures yielded identical results. Therefore, both the CIPAC and the AOAC methods may be considered as equivalent with good accuracy and reproducibility. After storage at 54°C for 14 days only one Diazinon dust formulation revealed a significant decrease in Diazinon content as shown by a t-test.

Accelerated Storage Test

A 44-day accelerated storage test at −4 °C was used to evaluate the relative effects of sodium erythorbate, disodium EDTA, and sodium tripolyphosphate on the development of oxidative rancidity in samples of minced sucker. Sensory testing and 2-thiobarbituric acid values were used to evaluate the changes in the samples. Sodium erythorbate was found to inhibit the development of oxidative rancidity as determined chemically and to contribute to maintaining a higher flavor score in the sensory testing.
