Abstract
A method to stabilized and impart color to strawberries, which can be fresh, or optionally IQF treated. This method comprises several stages including cuticle removal, alkalinization of the fruit pulp, infusion of a soluble stabilizing agent by immersion in an alkaline media to give the necessary firmness and texture integrity, infusion of dyeing agents by immersion in an alkaline color solution, fixation of said color and stabilizing agents in an acidic solution that has been enriched with polyvalent cations, and ulterior processes to preserve and extend the shelf life.
Claims8
A method for dyeing and stabilizing a strawberry, comprising steps of:
- a. immersing a strawberry in an alkaline solution and removing a cuticle layer of the strawberry, to produce a decuticled strawberry;
- b. immersing the decuticled strawberry in an alkalinizing, stabilizing, and dyeing solution comprising low ester pectin, carmine, norbixin, and ammonium hydroxide, to produce a stabilized and dyed decuticled strawberry;
- c. fixing the stabilized and dyed decuticled strawberry in an acid solution comprising ascorbic acid and calcium lactate, to produce a fixed, stabilized, and dyed strawberry;
- d. rinsing the fixed, stabilized, and dyed strawberry with clear water, to produce a rinsed, fixed, stabilized, and dyed strawberry;
- and
- e. pasteurizing the rinsed, fixed, stabilized, and dyed strawberry in a syrup.
