Shelf-life stability of Asparagopsis bromoform in oil and freeze-dried powder

Prolonging the shelf-life of freeze-dried G6PD reagent tubes.

evaluation of the physical stability of garlic powder dried by freeze and cabinet drying

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

Stability of prothrombin and factor VII in freeze-dried plasma.

The stability of prothrombin and factor VII was studied using accelerated degradation tests in three preparations of freeze-dried pooled normal plasmas. In a previous report (Brozović, Gurd, Robertson, and Bangham, 1971) factor X was shown to be relatively unstable in these preparations of freeze-dried plasma: it was calculated that up to 8% of the original factor X activity would be lost after...

Formulation and stability of freeze-dried proteins: effects of moisture and oxygen on the stability of freeze-dried formulations of human growth hormone.

This research presents the results of a series of stability studies on freeze-dried formulations of human growth hormone (hGH). Chemical decomposition via methionine oxidation and asparagine deamidation as well as irreversible aggregation are characterized by HPLC. Water sorption isotherms, DSC thermograms, and pulsed proton NMR data are also obtained. No glass transition temperatures are obser...

Production of a Semi Ready-to-Eat Shrimp Soup Powder and Assessment of Its Shelf Life

Background and Objectives: Macrobrachium nipponense are wetland crustaceans. The shrimp is rich in protein and unsaturated fatty acids (FAs). Therefore, the aim of this study was to use M. nipponense as a supplement for the preparation of a new soup. Materials and Methods: Nearly 40 kg of M. nipponense were harvested from Anzali Lagoon, Northern Iran. Shrimps were washed and dipped in NaCl sol...
