Process for reducing oil and fat content in cooked food with animal muscle protein in suspension
A product for cooking a food in oil and/or fat is provided. An adjusted pH protein suspension is produced in an aqueous or dry form and includes myofibrillar proteins and sarcoplasmic proteins substantially free of myofibrils and sarcomeres. The amount of oil and/or fat absorbed by the food during cooking is substantially reduced while the food retains its color and taste.
1. A process for obtaining an adjusted pH protein suspension for application to a food for being cooked in an oil/fat material, said process comprising the steps of:
A) solubilizing protein in an aqueous solution by decreasing the pH to a range that is between 2.5 and 4.0 to form an aqueous protein solution,
B) centrifuging the aqueous protein solution from Step A) to obtain an aqueous phase,
C) precipitating the protein in the aqueous phase of Step B) by adjusting the pH of the aqueous phase to a range that is between 4.5 and 7.5 to obtain a protein precipitate, and
D) comminuting the protein precipitate from Step C) to obtain an aqueous adjusted pH protein suspension having the comminuted precipitate wherein the aqueous adjusted pH protein suspension is used to coat or be mixed with food for being cooked in an oil/fat material to thereby reduce oil or fat content of the food when cooked, as compared to food not coated or mixed with said aqueous adjusted pH protein suspension.
2. The process of claim 1 further including, prior to step B), the step of filtering the aqueous protein solution.
3. The process of claim 1 additionally including the step of drying the aqueous adjusted pH protein suspension before being used to coat or be mixed with food prior to cooking.
