A controlled-release material sensitive and response to fouling organisms for an antifouling agent includes an encapsulating precursor and a crosslinking agent. A hyaluronic acid/polyL-lysine nano-shell controlled-release material is prepared by an alternating layer-by-layer self-assembly of hyaluronic acid and poly-L-lysine, and a polypropylene ammonium chloride/poly-L-glycine nano-shell controlled-release material is prepared by an alternating layer-by-layer sell-assembly of polypropylene ammonium chloride and poly-L-glycine. The crosslinking agent is composed of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and N-hydroxythiosuccinimide. Based on the specific catalytic hydrolysis characteristic of fouling organism extracellular proteases on the controlled-release material, the purpose of adjusting the release of antifouling agents adaptively with the change of fouling organisms in off-season/peak-season can be achieved, prolonging the service life of the antifouling coatings.

Food processing equipment, food contact surfaces, and non-food contact surfaces are sanitized or disinfected using an acid-anionic surfactant solution that has efficacy in hard water, is non-corrosive, and is stable at elevated temperatures. The sanitizing/disinfecting solution is prepared as a highly concentrated liquid and diluted to end use concentrations prior to application to food processing equipment or food or non-food contact surfaces. Efficacy in hard water is important for sanitizers and disinfectants that are diluted by the end user using potentially hard water. Stability at elevated temperatures is important for long-term storage and transportation. The diluted sanitizing/disinfecting solution exhibits strong antimicrobial activity against gram positive and gram negative bacteria even when diluted in hard water. The sanitizing/disinfecting solution exhibits low toxicity to humans and the environment since it is prepared from low toxicity ingredients that are readily biodegradable.
