Abstract: Disclosed are antimicrobial releasing agents, methods of preparing the antimicrobial releasing agents, and entrained polymers containing antimicrobial releasing agents. The antimicrobial releasing agent is prepared with a carrier having a pH below 3.5. The carrier is optionally polysulfonic acid, phyllosilicate, or others as disclosed. The antimicrobial releasing agent further includes an active compound such as a metal chlorite, and a trigger. Optionally, the antimicrobial releasing agent may be compounded into entrained polymers that release ClO2 in gas form.

Abstract: Disclosed are methods and systems for inhibiting melanosis. The methods comprise the step of placing a melanosis-susceptible object, such as a crustacean or a vegetable, into a closable container or enclosure and exposing the object to aldehyde. In another aspect, disclosed are anti-melanosic articles and polymer compositions that incorporate tea (preferably green tea), matcha or epigallocatechin gallate (EGCG) that function as anti-melanosic agents by releasing aldehyde.

Abstract: Disclosed are antimicrobial releasing agents, methods of preparing the antimicrobial releasing agents, and entrained polymers containing antimicrobial releasing agents. The antimicrobial releasing agent is prepared with an acidified hydrophilic material with a pH below 3.5 as a carrier, an active compound, and a trigger. The entrained polymer of the invention releases an antimicrobial agent in gas form, such as ClO 2 , optionally over a range of concentration from 150 ppm to 1800 ppm per gram of the entrained polymer under certain tested conditions.

Abstract: Disclosed are anti-melanosic releasing agents, anti-melanosic systems, and methods of preventing or reducing melanosis in crustaceans, particularly shrimp. Melanosis in shrimp is prevented or reduced by exposing shrimp to the anti-melanosic system containing the anti-melanosic releasing agent, e.g., green tea.
