How to make starch syrup ？
2018-05-17 / FAQ
Before answer the question how to make starch syrup, you should know that the starch syrup is use the starch as material to process syrup, include glucose, fructose and maltose, any grains contain starch(corn, rice, potato, cassava) can be the raw material to make starch syrup. Nowadays, to make starch syrup, the highest economic benefit method is the double-enzyme method. And the technical process of how to make starch syrup mainly can be divided into two parts: 1-starch liquefy, saccharify and transformation. 2-saccharified liquid purification and concentration.
Starch syrup making equipments in Doing Company
Part one: starch liquefy, saccharify and transformation
(1) The main material demand: starch (moisture:12%, purity:92%), enzyme(amylase, glucoamylase), complete set of starch syrup equipments.
(2) Detail operation of how to make starch syrup:
Add the starch and water with the ratio of 1: 3.5 into mixing tank to get a starch slurry, adjust the PH value to 6.0-6.2, then put into amylase for starch hydrolysis, then the starch liquefaction liquid pumped into saccharification tank, steam heating to 90-93℃ to make the saccharification reaction, then destroy the enzyme by high temperature, this time we can get the saccharification liquid, the enzyme used to make glucose and maltose is different. Above all, this is the first part operation for how to make starch syrup, and it's essential to tell you that if you want to make glucose syrup, you also need further process by isomerism system, also reaction by the enzyme, transfer the glucose into fructose.

Part two: purification and concentration:
(1) Adopt plate and frame filter press to filter the saccharification liquid, remove the impurities like protein, fat, the filter cloth is polyester canvas. If you want to get colorless starch syrup, also use plate and frame filter press to process, add activated carbon into the process, use the adsorption principle of activated carbon, then also filter the carbon out by plate frame filter press.
(2) Ion exchange system to purify the starch syrup, compared with the previous step, this process aimed to remove the different ions like Ca2+ and Mg2+ etc. to ensure the purity of syrup, normally, use the anion-cation process.
(3) Concentration process adopt the Doing Company professional evaporator to remove excess moisture, the concentration usually a large influence to the starch syrup color and lustre, especially the fructose easily to coking under high temperature, so we must control the temperature at about 60℃. This also an important point for how to make starch syrup.

Finally, about how to make starch syrup, we also need a quality standard for the starch syrup, better for your starch syrup making plant develop and operation.
1. Physical and chemical index:
2. Hygienic index
Sensory index: clarification, no abnormal odour, odorless, no impurities, no sediment.
Among this is our company answer for how to make starch syrup, in the large scale industrial starch syrup production, except the suitable technology, also need to equipped with good starch syrup equipments.
