Method of syrup production from starch

2018-08-27 /

Syrup production from starch is use the starch as material to produce syrup, include glucose syrup, high fructose syrup and maltose syrup. Syrup is widely used in food and beverage production, Because it's relatively cheap, starch production cost is cheaper. All kinds of starch can be used for syrup production, most of time, corn starch and broken rice are the first choice, but nowadays, potato starch, sweet potato starch, cassava starch also has been more and more popularin the syrup production industry.

Main raw material used for syrup production from starch include potatoes, corn, wheat, rice, etc., According to the nature of the raw starch and the catalyst used, the hydrolysis of starch into syrup has three methods: acid hydrolysis, enzymatic hydrolysis and acid enzyme method of syrup production from starch.

Syrup production equipments

For syrup production from starch, the enzymatic hydrolysis method is carried out under the action of an enzyme, and the reaction conditions are mild, and there is no need for equipment resistant to high temperature and high pressure or acid corrosion; the enzyme as a catalyst is characterized by strong specificity and few side reactions, so the purity of the hydrolyzed sugar liquid is high. High starch conversion, hydrolysis at higher starch emulsion concentrations.

High quality syrup after production from starch

For example, the acid hydrolysis method generally uses 10-12 Bx (containing 18% to 20% starch) starch milk, and the enzymatic hydrolysis method can use 20-23 Bx (containing 34% - 40% starch) starch milk, and crude raw materials can be used. The sugar liquid obtained by the enzymatic hydrolysis method is pure, light in color, non-bitter taste and high in quality, and is beneficial to the full utilization of the sugar liquid. For another, we have professional syrup filter machine used for protein filter, so please don't worry about the protein content. In fact, for syrup production from starch, with the development of enzyme preparation and application technology, enzymatic hydrolysis will gradually replace the acid hydrolysis process. DOING method of syrup production from starch is enzyme method.

Protein filter

Totally process of syrup production from starch is starch-mixing-liquefaction-deprotein-saccharification-decolorization-ion exchange-evaporation. Among these, enzyme adopted in the process of syrup production from starch is the liquefaction process and the saccharification process, which can change the starch into liquid syrup.

It's worth to tell you the liquefaction and saccharification step is the most important two parts of the glucose syrup production from glucose syrup. These steps performance influenced and decided the glucose products quality directly. So the advanced technology and equipments select to used for the syrup production from starch is very important.

Saccharification tank

For another, native starch consists of microscopic granules which with a complex internal structure. Under room temperature, these granules are insoluble in water. However, if a starch slurry is heated above 60 ℃, the granules will swell and rupture at last. This results in a dramatic increase in the starch slurry viscosity. At this point, the starch has been “gelatinized”. The gelatinized starch is now susceptible to attack by amylase enzymes. In practice, starch in gelatinized and partially hydrolyzed very rapidly in one step by heat-stable amylase. This step is called liquefaction. The partially degraded starch chains called dextrins are suitable starting materials for the later steps in syrup production from starch. In above, this is the description of the enzyme method used for the syrup production from starch, also the most advanced and newest method all over the world.
