Problems solved by technology

The production of the above-mentioned fermented products only utilizes the sugar in the waste molasses, and other inorganic substances such as potassium, sodium, magnesium and other minerals (total ash content reaches 12%) and organic substances such as phenolic pigments, amino acids, proteins and aromatic substances are left in the waste. In the mash, the COD and BOD of the downstream product wastewater prepared by fermenting molasses are very high, which brings a great burden to environmental protection treatment and poses a threat to environmental safety, becoming one of the pollution sources

Embodiment 1

[0028] A kind of method of utilizing molasses to prepare special sugar of the present embodiment, concrete preparation steps are as follows:

[0029] (1) the molasses (in the molasses, the mass fraction of the inorganic salts accounting for the total solids is 11.8%) is diluted with water to a Brix of 50°Brix to obtain diluted molasses;

[0030] (2) add milk of lime (being concentrated into the food-grade milk of lime of 8 ° of Be, the addition of milk of lime is 1.2% of the diluted molasses quality in terms of active ingredient CaO) and phosphoric acid in step (1) gained diluted molasses, adjust The total phosphoric acid value in the diluted molasses is 250ppm, the pH value is 7.3, and then heated to 85°C, enters the bubble-flocculation reactor, adds 1ppm flocculant polyacrylamide to fully react, and obtains the pretreated diluted molasses;

[0031] (3) The pretreated diluted molasses obtained in step (2) flows into the floating clarifier for solid-liquid separation, the scum...

Abstract

The invention belongs to the technical field of food processing, and discloses a method for preparing special sugar from molasses. The method comprises the steps of diluting the molasses, adding limemilk and phosphoric acid, performing heating, adding a flocculating agent, performing a full reaction, and carrying out solid-liquid separation by using a floating clarifier to obtain floating-clarified diluted molasses; filtering and separating the diluted molasses by using a stainless steel membrane and treating the diluted molasses with mixed anion / cation exchange resin in sequence to obtain desalted clear juice of the diluted molasses; and finally, evaporating and concentrating the desalted clear juice of the diluted molasses to 93-98 degrees Brix, adding an auxiliary agent, and uniformlystirring the components to obtain powder, thereby obtaining the special sugar of the molasses. According to the preparation method disclosed by the invention, most of original color, aroma and activesubstances in the original molasses are reserved, and the edible safety and nutrition of the special sugar are ensured. The method is of great significance for extending the traditional sugar industrychain.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing special sugar from molasses. Background technique [0002] Molasses is a by-product of the sugar industry and is a thick, dark brown, semi-fluid paste. The composition of molasses is complex. In addition to 30% to 50% of sucrose and reducing sugar, it also contains colloids, inorganic ash, flavonoids, polyphenols and macromolecular aroma substances. It has a strong caramel aroma and good nutritional value. . [0003] Molasses is an excellent fermentation and feed ingredient. At present, fermentation methods are generally used to prepare products such as alcohol, yeast, lactic acid, citric acid, and lysine. The production of the above-mentioned fermented products only utilizes the sugar in the waste molasses, and other inorganic substances such as potassium, sodium, magnesium and other minerals (total ash content reaches 12%) and organ...
