Problems solved by technology

At present, molasses is mainly used in the production of alcohol in China, but the waste water and waste residue discharged during the production process are not easy to deal with, and the finished alcohol is not suitable for long-distance transportation and sales, which seriously limits the digestion of molasses in alcohol factories.
[0004] The research of using molasses to produce caramel color has also been reported in China, and its technology mainly has the following disadvantages: the pretreatment of sugarcane molasses with technologies such as acid adjustment and ultrafiltration, first of all, the operation is complicated, the cost is high, and the unsafe factors in the production process increase; secondly , the colloid treatment is not thorough, the residual impurities affect the product quality and safety, and the product color rate is difficult to improve. The caramel color reported by most sugarcane molasses production is 20,000 to 30,000 EBC, and the highest is only 60,000 EBC, which cannot meet the requirements. User requirements, exceeding; In addition, the reaction requires high temperature and high pressure, high unit energy consumption, complicated process, cumbersome steps, and difficult to put into industrial production
The second is that sugarcane molasses contains a large amount of colloidal substances. During the heating process, the colloids will quickly denature and form water-insoluble particles, making the solution turbid, forming false colors, and losing the proper function of caramel color.

Embodiment 1

[0034] Adjust 50kg of sugarcane molasses with water, the mass percentage of water accounts for 78% of the total solution, and the dry basis of sugarcane molasses reaches 40%, then add phosphoric acid with a concentration of 85%, adjust the pH to 2.7, heat up to 98°C, maintain for 30 minutes, and cool to 50°C, use 98% sodium hydroxide to adjust the pH value, and adjust the pH value to 4.0.

[0035]Use perlite as a filter aid and filter through a filter press to obtain clarified molasses liquid. At this time, the mass percentage of molasses on a dry basis is 45%, a total of 78kg. The filtered clear liquid is centrifuged under 3500R / M centrifugal action After 20 minutes, the centrifuged sediment content was less than 0.1%; the pretreated molasses was concentrated by three effects to 75% by mass percentage on a dry basis, 46.8kg; the dry basis content in the total solids of the accurately measured molasses was 35.1kg , and add the catalyst in proportion to the total amount of sol...

Abstract

The invention provides a method for producing high color ratio double-strength caramel using cane molasses, which includes: a, pretreating cane molasses to remove gum, and filtering the molasses solution after neutralizing PH value; b, concentrating the pretreated molasses till the molasses accounts for 60%-80% of total molasses in weight percentage; c, adding solid catalysts, namely sodium pyrosulfite and ammonium bicarbonate; d, adding phosphoric acid to adjust the PH value to 5.5; e, heating and controlling temperature, and performing Maillard reaction; f, cooling caramel; g, blending, metering, and canning to obtain the finished product. The method overcomes a plurality of technical bottlenecks, and implements production of the high color ratio double-strength caramel using the cane molasses to replace white granulated sugar or glucose as material, and accordingly material cost is reduced greatly, and the molasses is turned into wealth. The color ratio of the double-strength caramel can be up to 120000EBC, and liquid catalysts such as traditional liquid ammonia, liquid sulfur dioxide and the like are replaced with the solid catalysts such as the sodium pyrosulfite and the like.

Description

technical field [0001] The invention relates to a production method of caramel color in food production, in particular to a method for producing double caramel color with high color rate from sugarcane molasses. Background technique [0002] Caramel color, commonly known as caramel color, is a natural food coloring obtained through caramelization or Maillard reaction of sugar substances, and has a wide range of applications. At present, the caramel color industry mainly uses white granulated sugar or glucose as raw material to produce caramel color through Maillard reaction. According to the color rate of the finished product, caramel color can be divided into two categories: single caramel color and double caramel color. At present, double caramel color is mainly used in the production of cola, tea drinks, candies, etc. Due to its high color rate and low dosage, it has obvious advantages compared with single caramel color in terms of dosage per unit of product and improvem...
