Background technique
Burnt sugar coloring is commonly called as caramel, caramel colorant, dark reddish brown etc., be saccharine material it is processed made of a kind of food color
Agent.Its apparent condition is dark brown liquid, solid or powder, has the distinctive burnt odor taste of caramel, is widely used in flavouring, sugar
It is that current Applications in Food Industry is widest in area, one of maximum food additives of quantity in the numerous foods such as fruit, beverage.
According to the difference of production method, food additives burnt sugar coloring is divided into four major class in the world, in the existing Chinese people
It is also described in republic standard GB/T 1886.64-2015 " national food safety standard food additives burnt sugar coloring ",
That is common law burnt sugar coloring, caustic sulfite method burnt sugar coloring, ammonia caramel color and sulphite ammonia caramel color.
To sulphite ammonia caramel color, in industry habit it is divided into again according to the height of absorbance single times of burnt sugar coloring and pair
Times burnt sugar coloring two major classes, generally sulphite ammonia caramel color by absorbance (610nm) lower than 0.19 are known as single times of burnt sugar coloring, inhale
Luminosity (610nm) is known as one of double caramel pigment in 0.19 or more sulphite ammonia caramel color.
The primary raw material for producing burnt sugar coloring is carbohydrate, such as: sucrose, starch syrup, xylose mother liquid, glucose are female
Liquid etc..Food additives burnt sugar coloring belongs to food color, and application is very extensive.The index for measuring its colorability is extinction
One of degree and the most important index of the product.The model that absorbance (610nm) requires in standard GB/T 1886.64-2015
It encloses than broad, is 0.01-1.00.Therefore, the absorbance of burnt sugar coloring product is multifarious in the market.With regard to one of double caramel pigment
Speech, the absorbance (610nm) of product in the market is usually 0.19-0.28 or 0.45-0.75.
Burnt sugar coloring is water-soluble food colorant, and the color that different product or various concentration are presented in aqueous can be palm fibre
It is yellow, reddish brown to dark brown.It is, in general, that the lower product of 610nm absorbance, red component is relatively high, is in aqueous solution
Existing color is relatively partially yellow or red.And the higher product of 610nm absorbance, red component are relatively low, are in aqueous solution
Existing color is relatively partially reddish brown or dark brown；Burnt sugar coloring 510nm absorbance can be also measured in China, industry, in other countries
Such as the U.S., then can measure burnt sugar coloring 560m absorbance, so as to measure product red component number.
When producing brown granulated sugar, brown granulated sugar crystal is separated with mother liquor by centrifuge cane sugar factory, i.e., brown granulated sugar is cut
It stays in centrifuge cloth bag, it is molasses that mother liquor, which enters reservoir,.In order to cater to the demand of user, finished product brown granulated sugar will have certain color

Loss on drying index has Compulsory Feature, i.e. loss on drying (g/100g)≤3.5.Therefore, if producing drying with the prior art
Weightless brown granulated sugar that meet national standards often not enough enables customer satisfaction in terms of coloration and sugared fragrance.To sum up, the prior art
In, if being used to beat sweet process for the lower burnt sugar coloring of absorbance or the lower one of double caramel pigment of absorbance, not only dosage is opposite
It is larger, and the color red component of brown granulated sugar relatively high (i.e. inclined light color), sugared fragrance not enough (dark molasses dosage is very little),
Loss on drying is easy exceeded；If the higher burnt sugar coloring of absorbance is (double such as common absorbance 0.45-0.75 in the market
Burnt sugar coloring) for beating sweet process, the color red component of brown granulated sugar is relatively low (i.e. partially old color or ash are dark-coloured).User's preferences
Brown granulated sugar is dark brown red to dark brown so-called natural color, then to there is preferable sugared fragrance in terms of fragrance.
In consideration of it, needing to develop a kind of new burnt sugar coloring, to make up drawbacks described above.
