Abstract

The invention discloses a caramel essence used in coffee and a preparation method thereof. The caramel essence used in the coffee is composed of a thermal-reaction-typed caramel essence and a blended-typed caramel essence, wherein the mass of the blended-typed caramel essence is 0.01-1.00% of that of the thermal-reaction-typed caramel essence. The thermal-reaction-typed caramel essence consists of following components, by weight, 3.33% of glycine, 7.98% of anhydrous glucose, 57.65%-62.08% of 1,2-propylene glycol and the balance distilled water. The blended-typed caramel essence consists of following components according to a certain mass percentage ratio: 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, 2,3,5-trimethylpyrazine, furfural, furfuryl alcohol, phenylacetaldehyde, 10% of capraldehyde, 10% of furanone, methyl cyclopentenolone, 5% of ethyl maltol, cocoa powder tincture and the balance propylene glycol. The caramel essence used in the coffee is soft and natural in fragrance, has a thick fragrance, is mellow in mouthfeel, is less in addition amount when being used in coffee products and has a significant effect.

Description

technical field [0001] The invention belongs to the field of food ingredients, in particular to a caramel essence for coffee and a preparation method thereof. Background technique [0002] Caramel flavor is an important food additive, which has been widely used in tobacco, candy, beverage and other products. At present, the production methods of caramel essence are mainly based on two methods: the preparation of synthetic food spices and the preparation of amino acids and sugars by Maillard reaction. The caramel essence blended with synthetic spices has a simple production process and strong fragrance intensity, but due to the limitation of the variety of spices, the aroma is not realistic and natural; it is prepared by Maillard reaction with amino acids and sugars as raw materials Although the caramel essence obtained by the method has a strong natural flavor, it also has problems such as insufficient aroma characteristics, short fragrance retention time, and low intensity...
