A Production Process for Improving Double Caramel Flavor

Abstract

The invention discloses a production process for improving the flavor of double caramel color, which comprises the following steps: 1) additionally adding Lewis acid and acylating agent as catalysts during the first pressurized reaction in the double caramel color reaction process; During the second pressure reaction, metallocene catalyst and Lewis acid were additionally added as catalyst; 2), after the double caramel color reaction was completed, the material was cooled to 80°C, and 5-guanylic acid and monosodium glutamate were added, Stir well, cool and filter. In the present invention, by using Lewis acid and acylating reagent, the generation of azido groups in the reaction process is suppressed, the generation of bitter substances is reduced, the flavor of the product is controlled, and the consumption of sulfite and ammonium salt is reduced by adding a metallocene catalyst, and the reaction temperature is lowered. Control the flavor of the product; by adding 5-guanylic acid and monosodium glutamate to season the caramel color, a synergistic effect occurs between each additive, reducing the bitterness and burnt taste of the caramel color, and improving the flavor of the caramel color product.

Description

technical field

[0001] The invention relates to the technical field of caramel color production, in particular to a production process for improving the flavor of double caramel color. Background technique

[0002] Caramel color, commonly known as caramel color, is the most used food coloring agent in my country, and its usage exceeds more than 90% of the entire food coloring agent. According to different production processes, caramel color is usually divided into four categories: common method caramel color, caustic sulfite method caramel color, ammonia method caramel color and ammonium sulfite method caramel color. The properties, physical and chemical indicators, and hygienic indicators of the caramel-colored products obtained with different catalyst types and dosages will be very different, especially the color rate of the products will also be very different.

[0003] For caramel color by ammonium sulfite method, it is customary in the industry to divide it into two ca...
