“…By contrast the antimicrobial activity of propylene glycol is not enhanced by addition of up to 70% sorbitol. 8 This indicates an osmotic effect of glycerol. In a preliminary experiment the antimicrobial effect of glycerol 85% and undiluted propylene glycol upon A. niger spores was tested.…”

“…It is reported that the growth of A. niger is inhibited by glycerol concentrations larger than 50% and by propylene glycol concentrations larger than 10%. 8 Other authors describe a fungistatic effect at a propylene glycol concentration of 30% and a fungicidal effect at !40%. 9 Due to a synergistic effect the minimum concentration of glycerol required for an antimicrobial effect is decreased in mixtures with more than 20% sorbitol.…”

“…The effect of A. niger spores on the sorbic acid concentration was tested at three different pH values with the formulations 13, 14, and 15 (glycerol 28%, propylene glycol 12%, sorbic acid 0.05%, pH 5,7,8). One hundred milliliters of each formulation was inoculated with 1 mL stock suspension in triplicate.…”

Substitutes for nitrites were used in turkey frankfurter slurries to determine their effectiveness at inhibiting Clostridium botulinum. Spice extracts of mace, bay leaf, nutmeg, white pepper, and black pepper were tested. A solution of Lauricidin in distilled water and a solution of Lauricidin in propylene glycol were also tested. Botulinal inhibition was achieved using a 5% solution of Lauricidin-propylene glycol resulting in further testing of different levels of propylene glycol alone or in combination with lowered levels of sodium nitrite.Spice extracts of mace (31 ppm), bay leaf (125 ppm), and nutmeg (125 ppm) effectively inhibited C. botulinum toxin production. Propylene glycol at the 6.2% level, in combination with 31 ppm sodium nitrite, and 9.1% propylene glycol, in combination with 24 ppm sodium nitrite, proved to be effective inhibitors of C. botulinum in turkey frankfurter slurries.

“…This process was performed to obtain the percentage of water for each albumin. Photosensitive emulsion (ADPHA) was prepared using holographic recording analysis on films sensitized with ammonium dichromate (NH 4 ) 2 Cr 2 O 7 (AD) [3]- [5], propylene glycol (P) [6]- [8] with hen albumin (HA). In addition to holographic recording analysis, the photosensitive emulsion (ADPQA) method was produced with quail albumin (QA).…”

Holographic recording analysis was performed on the films that were sensitized with ammonium dichromate with albumin of hen and quail (Gallus gallus and Callipepla cali) as abiopolymeric photosensitive matrix. The samples were exposed to an He-Cd laser, λ = 442 nm, at various concentrations, and diffraction efficiencies were measured as a function to the energy, thickness, protein density, aging time, and spatial frequencies. The photosensitivity was measured as a function of storage time, and the gratings were recorded in real time. The photochemical processes involved in the formation of holographic image are described. The results indicate the behavior of colloidal systems based on albumin bird build holographic recording materials.
