Embodiment 1

[0029] Take 1kg of glucose sample, add 2kg of distilled water to shake and mix and fully dissolve; then add 0.5kg of NH 4 Cl, to get glucose and NH 4Cl mixed solution, the mixed solution is pumped into the atomizer in the spray drying equipment with a peristaltic pump. The spray reaction conditions are as follows: the hot air inlet temperature is 270°C; the flow rate of the hot air entering the drying equipment is set at 1m3 / min; the flow rate of the mixed liquid pumped into the spray drying equipment is set at 30mL / min; The length of the heat preservation flow channel (12 cm in diameter) is 15 cm, the reaction time is 3 seconds, and the outlet temperature is 145° C. After the spray-drying reaction treatment, the water content in the Maillard product is measured to be 0.4% by mass; the obtained reactant is then fluidized and vibrated-dried to obtain a powdery caramel pigment product. Dissolve 0.01g of caramel pigment product in 10mL of distilled water, measure the absorbance...

Abstract

The invention discloses a method for preparing a powdery caramel pigment by using a spray drying technology, belonging to the technical field food processing. In the method, the powdery caramel pigment is prepared by undergoing a Mailard reaction on reducing sugar or an oligosaccharide or polysaccharide which is hydrolyzed into reducing sugar under the acid condition and a compound for providing amino by adopting a spray drying technology. The spray drying reaction conditions are that: (1) the temperature of the hot air inlet of spray drying equipment is 160-270 DEG C; and (2) the reaction time is controlled at 3-60 seconds by controlling the flow of hot air entering the spray drying equipment and the flow of a mixed solution pumped into the spray drying equipment or selecting the lengths of heat-preserving flow channels of a spray drying chamber and a gas-solid separating system. The method has the characteristics of short time and flow needed for preparing a food caramel pigment, continuous reaction process, easiness for controlling the quality, high solid content, contribution to realizing industrial preparation, and the like.

Description

technical field [0001] The invention relates to the Maillard reaction in the field of food processing, in particular to a method for accelerating the Maillard reaction by using spray drying technology. Specifically, the spray drying technique is used to make Maillard reaction between reducing sugars or oligosaccharides or polysaccharides hydrolyzed into reducing sugars under acidic conditions and compounds providing amino groups to prepare caramel pigment raw materials required in food. Background technique [0002] Maillard reaction, also known as Amino-carbonyl reaction, refers to the condensation and polymerization of compounds containing hemiacetal hydroxyl groups (aldehydes, reducing sugars) and compounds containing amino groups to form high-molecular-weight polymers. Substance-Melanoidin (Melanoidin) reaction. The Maillard reaction was first discovered by the famous French chemist Maillard in 1912 when he heated a mixed solution of glycine and glucose. Today, the Mai...
