Description
Technical field
Present invention relates in general to quaternary ammonium salts and cationic (co) polymer to clarify during the production of crystalline sugars or raw sugar
The purposes of sugar-cane juice.The invention further relates to a kind of for producing the new method of crystalline sugars or raw sugar from sugar-cane juice.More specifically, this
Invention describe it is a kind of for by before clarification steps, period or just after addition quaternary ammonium salt and cationic (co) polymerization
Object is come the clear method of phosphatization that improves crystalline sugars or raw sugar.It additionally provides a kind of (total) poly- comprising quaternary ammonium salt and cation
Close the kit of object.
Background technique
According to Food and Agricultural Organization of the United Nations (FAO, 2015), world's candy output estimation in 2014/2015 year reaches
1.81 hundred million tons, moderately increases by 0.2% than 2013/2014 season, but still be the second largest harvest in history, and Brazil is still most
Big producing country, wherein yield is estimated as 37,500,000 tons.
Sugarcane is main production sugar, and world's candy output from sugarcane is about than coming from beet (another main sugar
Source) it is six times greater.Sugarcane is to have been determined as the several high perennial of field-crop in all Perenniporia martius country in the world
One of true dogstail species, and gradually improve sugared production method.
Currently, in cane mill industry, it is deimpurity effective applied to being gone from sugar-cane juice during manufacture finding
Technical aspect has had very big interest.These effort reflect the growth to the food product containing minimum chemicals
Demand, and therefore, emphasis, which has been placed into, to be improved the quality of sugar, provides in white crystalline material.
Because color is one of most important sugared quality standard, this respect has been assessed and has had studied
New method is to reduce sugared color, and in the final product without any chemicals trace.
For including extracting sugar-cane juice from the sugarcane of harvest from the conventional method of crystalline sugars and raw sugar is produced in sugarcane.Make
Sugar-cane juice is subjected to purifying (also commonly referred to as clarifying), generates crystalline sugars or raw sugar.Raw sugar can be provided by re-melting syrup or
Liquid glucose is the raw material for producing refined sugar.
When sugared production method starts, sugar cane juice clarification is the most significant steps to market supply sugar best in quality.?
In the 1950s, developing the sugar cane juice clarification technology for being referred to as sulfiting for producing sugar in India.It is this usual
Defecation method be related into juice add sulfur dioxide (SO2) to separate non-sugar ingredient, including coloring matter.Pass through this method
The sugar of production contains the sulphur of about 20ppm or more, and this pollutant causes health and environmental problem and becomes difficult to
Received in food and beverage market.
In beet sugar industry, it is known that the method for another kind clarification beet juice referred to as carbonates.This method includes addition
The slurry of calcium hydroxide and carbon dioxide gas is bubbled so as to winnofil.When being applied to sugarcane, this type method
It is consumed excessively by some problem, especially lime, this causes this method economically unsustainable.Really, both
Sugar source has the property difference of different compositions, especially non-saccharide and beet does not have any reduced sugar.In some cases,
This method can be applied to refined sugar clarification, but be not applied in the raw sugar from sugarcane/crystalline sugars production.WO 2014/011496
Such carbonating process using polymer color precipitating reagent is disclosed with FR 2578238.
In purification sugar industry, common defecation method is phosphatization clarification.This method principle is based on through addition phosphorus
Acid and lime carry out precipitated calcium phosphate.
Itd is proposed many chemical addition agents with by phosphatization come precipitated impurities during purifying sugar.But these are created
New plan is mainly developed in the purification step of sugar industry, for example, U.S. Patent number 3,698,951 and WO 2011/
060168 and U.S. Patent number 5,865,899 describe sugar refining method, wherein by addition dialkyl dimethyl quaternary amine surface
Activating agent makes syrup and Sugarcane juice decolorization.
From Food and Drug Administration, 21 CFR Ch.I of HHS § 173.400Pt.174 (4-1-00 editions) is it is known that two
The bis- octadecyl ammonium chlorides of methyl-(DHT) are by " as the decolorising agent under following limitation in the clarification of refinery's liquid glucose: 1) existing
Only in the purification of liquid glucose purification/clarification stage addition, amount is no more than food additives described in (a) (1) section of this part
700 parts per million by weight of sugared solid."
However, even if, when being applied to the method for production crystalline sugars, performance is not also made us enough under this very high amount
Satisfied industrially implementation.
Therefore, main path has been made to come from syrup and liquid glucose to optimize refining methd by defecation method to reduce
Sugared color, these syrup and liquid glucose formerly before production raw sugar or the step of crystalline sugars in clarified and therefore presented
Less impurity and lower initial degree of staining.Really, it is had differences between syrup or liquid glucose and sugar-cane juice, syrup and liquid glucose
It is the raw sugar of fusing, they are more concentrated and have less impurity, these impurity quilt in the preview step of sugar refining method
Removal, on the other hand, sugar-cane juice are the juice directly extracted from broken complete or peeling the sugarcane in grinder.
From Food and Drug Administration, HHS, 21 CFR Ch.I (4-1-12 editions), the 173.60th section is known to be dimethylamine-
Epichlorohydrin copolymer (DMA-Epi) is " food additive as decolorising agent and/or flocculant in refinery's liquid glucose and clarification of juice
Add agent., only in the purification of liquid glucose purification/clarification stage addition, concentration is no more than the copolymer of sugared solid by weight for it
150 parts per million." however, realizing the sugarcane in production crystalline sugars or the method for raw sugar for the amount more than regulation limitation
Superperformance in juice clarification.
In view of the above, up to the present, not for improving the defecation method of sugar-cane juice to obtain crystalline sugars or original
The solution of sugar.
Therefore, the purpose of the present invention is to one kind for when producing crystalline sugars or raw sugar, it is preferable to use phosphatization principle is clear
The solution of the optimization of clear sugar-cane juice.
Another object of the present invention be propose it is a kind of production have it is less colored degree and therefore can be by food, drug and drink
The ameliorative way of crystalline sugars or raw sugar that material industry is received.
Another object of the present invention is to propose a kind of more effective way, this method have less consumption chemicals,
It is lesser to corrode and be easier to control.
Summary of the invention
Therefore, the invention proposes quaternary ammonium salts and cationic (co) polymer to clarify during the production of crystalline sugars or raw sugar
The purposes of sugar-cane juice.Preferably, object of the present invention is to quaternary ammonium salt and cationic (co) polymer crystalline sugars or raw sugar production
Period passes through the purposes of phosphatization clarified sugar cane juice.
The present invention also provides a kind of methods for producing crystalline sugars or raw sugar, method includes the following steps:
A) sugar-cane juice is extracted from sugarcane；
B) clarified sugar cane juice preferably passes through phosphatization；
C) clear sugar-cane juice is evaporated；
D) crystallize clear sugar-cane juice；
E) it is centrifuged and dry.
Wherein before the clarification steps, period or just after, addition quaternary ammonium salt and cationic (co) polymer.
A further object of the invention is a kind of kit, which includes:
Quaternary ammonium salt,
Cationic (co) polymer, and
Optionally phosphorus source.
