  • Patent number: 10912321
    Abstract: Methods for treating poultry during processing for increasing the weight of the poultry are disclosed. The methods may be performed in a chill tank or other reservoir and utilize either equilibrium peracetic acid or non-equilibrium peracetic acid. The non-equilibrium peracetic acid may be prepared from hydrogen peroxide and a liquid acetyl precursor, such as triacetin. The methods comprise contacting a poultry carcass with peracetic acid-containing water at a pH of about 6 to about 9. The methods result in an increase in the weight of the processed products and an increase in a processing plant's percent yield of the processed products.

  • Patent number: 10004230
    Abstract: Methods for the generation of non-equilibrium solutions of peroxyacetic acid are disclosed. These methods comprise introducing triacetin and aqueous hydrogen peroxide to water, mixing, and then adding an aqueous source of an alkali metal or earth alkali metal hydroxide. Triacetin is converted rapidly and with a high conversion rate into peracetic acid. These methods produce solutions with a high level of peracetic acid.

  • Patent number: 9370180
    Abstract: Methods and compositions for the generation of a peroxyacetic acid sanitizer in proximity to the point-of-use are disclosed. These methods comprise introducing a hydrogen peroxide-acetyl precursor solution to water, mixing, and then adding an aqueous source of a alkali metal or earth alkali metal hydroxide. Triacetin is a preferred acetyl precursor and is converted rapidly and with a high conversion rate into peracetic acid. These methods produce solutions with a high level of peracetic acid. Methods for preparing the hydrogen peroxide-acetyl precursor solution are also provided. Also disclosed are solid compositions comprising a liquid acetyl precursor, a water-soluble source of hydrogen peroxide, and a water-soluble source of alkalinity. The solid composition is a freely-flowable solid that is used as a bleaching agent and a stain remover for the treatment of articles such as fabrics, dentures, textile garments, and equipment used in the food and beverage industry.

  • Patent number: 8574605
    Abstract: The invention includes convenient methods of preparing: (1) highly concentrated liquid bromine-containing biocidal solutions, (2) highly concentrated mixed halogen liquid bromine and chlorine-containing biocidal solutions, and (3) high-activity bromine-containing biocidal solids, all having excellent physical and chemical stability. One method yields solutions that have concentrations of bromine in excess of 18% as Br2 (8% as Cl2) in which the mole ratio of hydroxide ion to hydrogen ion source is at least 1.9:1. Another method employs elemental bromine in conjunction with a solid organic or inorganic halogenating agent to yield halogen solutions at concentrations greater than 22.9% as Br2 (10.2% as Cl2). This method can be performed under conditions that exceed the solubility of the active ingredient such that it crystallizes and is recovered as a hydrated or anhydrous salt in good yield.

  • Publication number: 20110200685
    Abstract: The invention includes a method of preparing hypochlorite-activated solutions of hypobromous acid and/or hypobromite ion. The method includes the steps of mixing a solution of a source of bromide ion with a solution of a source of hypochlorite ion to activate the bromide ion, allowing sufficient time to maximize the activation of the bromide ion, and storing the solution before use. The invention also includes a method of using the solution to wash meat and poultry carcasses, trim, and offal to reduce pathogenic microorganisms. The solutions may also be used to reduce pathogenic microorganisms in industrial cooling water and on food contact hard surfaces and equipment. The solutions may be stored for up to about three hours before use and are stable for that period of time.
