Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for purifying a sugar solution. Furthermore, the glycerin fatty acid ester consisting of saturated fatty acids having 8 to 22 carbon atoms or unsaturated fatty acids having 8 to 22 carbon atoms or mixed fatty acids is added to the total starch-containing Yano 1 solution. This invention relates to M't'7 manufacturing method for sugar solution that completely removes starch.

Sebe raw material sugar is obtained by squeezing cane and cleaning the sesame juice, followed by concentration, crystallization, and crystal separation.

In raw sugar production plants, it is desired to recover and manufacture crystalline quality raw sugar from the sugar in cane in the most economical and efficient manner.

To achieve this objective, the sugar content in cane and the impurity M
] composition and amount are major factors. In particular, the composition and amount of impurities depend on the variety of sweet potato, weather conditions, soil, and other growth conditions.
It depends on ripening conditions at the time of harvest, storage and transportation conditions after harvest.

Therefore, how efficiently these impurities can be removed is essential in the sugar manufacturing process.

Impurities in cane juice include reducing sugars, starches, nitrogen compounds, mountain acids, inorganic salts, waxes, lipids, and pigments, and the quantitative ratios of these may vary depending on the conditions described above.

Ingredients! The removal rate of impurities in the cleaning process of the manufacturing plant is about 50 cm in total h4, and impurities that cannot be removed will cause foaming, decrease in filtration efficiency, i
ii% M7°1 This results in many negative effects such as a decrease in M7°1 efficiency, interference with crystallization, a decrease in the fluidity of the sugar solution, and a decrease in the crystal content C: [ability.

The main cleaning method at raw material paste manufacturing factories is adding lime and heating.Soluble inorganic salts and organic acids in cane juice precipitate as insoluble lime salts, and protein colloids, which are nitrogen compounds, can be coagulated and removed by heating. It has been confirmed that these precipitates can adsorb and remove pigments, waxes, lipids, etc., based on the activity of their particle surfaces.

It is known that 0.05 to 0.1 g of starch is contained in sweet potato, but it is known that about 30% can be removed in the above-mentioned cleaning process, and about 70% remains in sweet potato and foams. It does not cause any interference with the glaze in the raw material paste manufacturing process, such as a decrease in filtration efficiency, and it does not have a large effect on the "F\V Sugar Refining Product* (floc potential)."

The conventional method of removing starch in sweet milk is adding starch-degrading enzyme to the lime milk before it becomes saturated.
Attempts have been made to reduce starch, but this method only converts starch into low-molecular-weight saccharides, and does not remove starch, so it has not been a drastic measure.

The present invention has been completed by discovering that starch, which has been difficult to remove in the past, can be efficiently removed by a simple operation.

In other words, starchy sugar solutions such as Setojiru contain 8 or more carbon atoms.
By adding a glycerin fatty acid ester consisting of a single or mixed fatty acid of 22-saturated fatty acid or unsaturated fatty acid having 8 to 22 carbon atoms, dispersing, suspending, emulsifying or dissolving it, and stirring it, it can be efficiently prepared. It was possible to remove starch from the sugar solution.

711) Such a method had never been used in the purification of sugar solutions.

The sugar solution in the present invention refers to monosaccharides such as glucose and fructose,
A sugar solution containing starch, consisting of trisaccharides such as sucrose and maltose, or trisaccharides such as raffinose, alone or in combination. These sugar solutions include, for example, IIJ' sucrose solution, beet sugar solution,
These include glucose solution, isomerized sugar solution, and starch syrup solution.

- Starch in the present invention includes cane, rice, corn, potato, sweet potato, tapioca, sugar beet,
It includes starch such as wheat, soluble starch, dextrin, starch such as British gum, or its decomposition products, and vegetable gums such as gum arabic, guar gum, locust bean gum, and pectin, which are composed of polysaccharides.

The constituent fatty acids of the glycerin fatty acid ester used in the present invention are saturated fatty acids having 8 to 22 carbon atoms and/or 8 to 22 carbon atoms.
08-22 unsaturated fatty acids can be used, specifically caprylic acid, capric acid! ji>1, lauric acid, myristic acid, palmitin IN1? unsaturated fatty acids such as stearic acid, arachidonic acid, linoleic acid, linoleic acid, linoleic acid, linoleic acid, arachidonic acid, erucic acid, or coconut oil. , palm oil, soybean oil, cottonseed oil, rice bran oil, beef tallow, lard, anti-fat oil, fish oil, etc. The fatty acids of these hydrogenated oils can be used.

Glycerin fatty acid ester contains unyielded diester called reactive monoglyceride; Fr mono- and dimonoglyceride and monoester combination; 90%
Although there are the above-mentioned distilled monoglycerides, for the purpose of the present invention, the distilled monoglycerides produced by Monoester Co., Ltd. are more preferable.

In the present invention, the amount of lycerine fatty acid ester added to the sugar solution containing starch is from 92.5 to 92.5, based on the starch solid content.
Shows favorable effects with 30 heavy assets. If it is less than 2.5 weight ratio, no starch removal effect can be expected, and if it is 30 weight φ or more, it is not necessary from the point of view of economy and effectiveness. Practical size 11

Next, the present invention will be explained with reference to examples, but the present invention is not limited to the examples.
