Storage Conditions and Screening of Koji Molds for Starch Hydrolysis in Dried Unripe Apple Pulp

SCREENING FOR STARCH-HYDROLYSING BACTERIA

Screening of3000 soil samples collected from cities of four different provinces of Iran for starch-hydrolysing bacteria revealed that the nature is enriched with Streptomyces species capable of producing amylolytic enzymes. Among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characteriza...

Optimum Hydrolysis Conditions of Cassava Starch for Glucose Production

Acid and enzymatic hydrolysis of cassava starch to glucose (fermentable sugar) were investigated and compared. And the effects of acid concentration, pH, temperature and time on the yield of glucose were studied. Experiments were carried out at a temperature range of (60 – 100)C between 30 minutes and 4 hours. (0.2 – 1.0)M strength of H2SO4 acid was used and pH values range of 4 – 7 was conside...

Antioxidant responses of Golden delicious apple under cold storage conditions. Nader Chaparzadeh* and Bahram Yavari

An understanding of biochemical events of cold storage may lead to more effective methods of preventing apple fruits from ripening and keeping their quality. This study aimed at determining the level of reduced and oxidized forms of ascorbic acid, and the activity of ascorbate peroxidase, catalase, and superoxide dismutase enzymes changes in pulp of Golden delicious apple cultivar during cold s...

Correlation between Wheat Starch Annealing Conditions and Retrogradation during Storage

Yu K., Wang Y., Xu Y., Guo L., Du X. (2016): Correlation between wheat starch annealing conditions and retrogradation during storage. Czech J. Food Sci., 34: 79–86. The effects of annealing conditions on the degree of retrogradation (DR) in wheat starch were analysed by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Three annealing parameters were varied, namely moisture (...
