Abstract: Preservative compositions using GRAS (generally recognized as safe) ingredients are incorporated into a commercially viable three-stage preservation process for mushrooms. The process includes contacting the mushrooms with a high pH solution for microbial reduction; a neutralizing step to return the pH of the mushrooms to their about physiological pH; and an anti-browning step that incorporates suitable antioxidants and ancillary compounds to maintain the color of the finished product. Specifically disclosed is a method for preserving fresh mushrooms comprising the steps of exposing the mushrooms to a aqueous anti-microbial solution with a pH of 10.5-11.5; treating the mushrooms with a pH neutralizing buffer consisting of an organic acid and a salt of an organic acid and then subjecting the mushrooms to a combination of an anti-browning agent, a source of calcium and a chelating agent.

Abstract: Compositions and processes are disclosed for treating fresh-cut apple pieces by dipping cut apple pieces in an aqueous solution containing GRAS (Generally Recognized As Safe) substances that protect the cut apple pieces from deterioration due to increased enzymatic activity, oxidative reactions, water migration and microbial effects during the extended shelf life of the fresh-cut apples pieces. The composition consists principally of L-cysteine, sorbitol and calcium chloride. A chelator such as sodium hexametaphosphate can be added to enhance the affiance of the agent. A synergistic effect is observed when apple pieces are packaged in a film that will equilibrate to oxygen and carbon dioxide levels in the range of 0.5-5.0% and 7.0-37.0%, respectively.

Abstract: An apparatus for administering treatments to pre-packed boxes of produce, comprising: a main frame defining a space sized and configured to receive a plurality of vertically stacked, pre-packed boxes of produce, each box having at least one pair of through hand holes located in opposing ends thereof, a first injector frame moveably mounted to the main frame opposite one of the two opposing sides of the vertically stacked boxes and a second injector frame moveably mounted to the main frame opposite the other of the opposing sides of the vertically stacked boxes; a plurality of spray injectors in fluid communication with a solution holding tank and with means to pump solutions from said holding tank to said spray injectors, the spray injectors being adjustably mounted on the injector frames, with a spray injector positioned in alignment with each hand hole exposed on each of the two opposing sides of the vertically stacked boxes; means to move the injector frames between a first position in which the spray inje

Abstract: A process is disclosed for inhibiting enzymatic browning in raw, peeled potatoes comprising dipping the potatoes in a solution of heated organic acids (45-65.degree. C.), followed by treatment in a weakly basic solution to neutralize the potato surface and treatment with reducing agents, followed by storage in modified atmosphere packaging. The process may comprise two stages, in which sodium erythorbate in solution (approximate pH 7.8) is used both as the neutralizing agent and the reducing agent. Alternatively, the process may comprise three stages, in which a solution of the salt of an organic acid (such as sodium citrate) is used to neutralize the potato surface following the heated acid dip, and a third stage containing the reducing agents sodium erythorbate and erythorbic acid are combined at a final pH of greater than 4.3. Chelating agents or sequestrants may be added to the solutions.

Abstract: A method for inhibiting the deterioration of processed fresh broccoli during shipment, comprising the steps of processing the broccoli for fresh consumption and exposing the processed broccoli to a solution of sodium citrate, ascorbic acid, sodium acid pyrophosphate, and L-cysteine hydrochloride, and water in which the sodium citrate, ascorbic acid, sodium acid pyrophosphate, and L-cysteine hydrochloride have been diluted to a combined weight percentage concentration of from about 1.00 to about 1.
