Embodiment 1

[0034] The present invention is a production process for improving the acid resistance of double caramel color, comprising the following steps:

[0035] 1), raw material metering concentration: the dry matter is 6000kg DE value of 97% glucose syrup is metered into the reaction tank, and concentrated to dry basis is 60%;

[0036] 2), a catalyzer: add sodium sulfite 120kg, ammonium sulfite 60kg in the already concentrated glucose syrup, open and stir and mix well;

[0037] 3), pressurized reaction for the first time: the above-mentioned syrup added with the catalyst is pressurized and heated up in the reaction tank, and the pressure gauge pressure in the reaction process control tank is 0.4Mpa, and the temperature in the tank is 150 ℃, and sampling is detected every 30 minutes. Its color rate, when the color rate is 0.190 (converted to EBC unit is 0.190÷0.076×20000=50000EBC, the same below) terminates a reaction;

[0038] 4), secondary catalyst: add 120kg of liquefied ammonia t...

Abstract

The invention discloses a production technology for promoting the acid resistance of double caramel color. During a second pressurized reaction in the reaction process of double caramel color, a halogen-free solid super acid taking a metal oxide or SO4<2-> as an accelerant is added as a catalyst; after the reaction of double caramel color is finished, materials are cooled to 70 DEG C, polymerization inhibitors are added in the stirring process, and the polymerization inhibitors are ferric trichloride and copper chloride. According to the production technology, the acid resistance of double caramel color can be improved effectively by using the specific solid super acid and the specific polymerization inhibitors, the production technology is effectively applicable to higher acid requirement, and the quality and preparation of beverage cannot be influenced.

Description

technical field [0001] The invention relates to the field of colorants, in particular to a production process for improving the acid resistance of double caramel color. Background technique [0002] Caramel color, commonly known as sauce color, is the most widely used food coloring agent in my country, and its usage exceeds more than 90% of the entire food coloring agent. According to their 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 color ratio, properties, physical and chemical indicators, and hygienic indicators of the caramel-colored products obtained by different types and amounts of catalysts will be very different. [0003] Double caramel color is a kind of ammonium sulfite method caramel color, because double caramel color has both high color ratio and good acid resistance, it is wid...
