Embodiment 1

[0018] Embodiment 1: the influence of nanofiltration membrane material on the removal rate of sucrose in brown sugar

[0019] 1. Materials and Methods

[0020] 1) 400Da nanofiltration membrane material: composite polyethyleneimine, polyamide

[0021] 300Da Nanofiltration Membrane Material: Polyamide

[0022] 800Da Nanofiltration Membrane Material: Composite Chitosan

[0023] 2) Take 3.0kg of brown sugar, dissolve it in purified water to 15L, and filter it with a 0.45μm microporous membrane. The filtrate is divided into three parts of about 5L each, and the nanofiltration materials made of composite polyethyleneimine, cellulose, and composite polyamide are used respectively. Membrane desugaring, operating pressure 1.0Mpa, operating at room temperature, collecting nanofiltration concentrate and when the volume of the concentrate reaches 1L, make up the volume to 5L, repeat the operation 3 times, and when the concentrate is enriched to a specific gravity of 1.05-1.10, respectiv...

Embodiment 2

[0027] Embodiment 2: the preparation of sugar-free brown sugar

[0028] Take 2.0kg of brown sugar thick paste boiled after sugarcane pressing and clarification, dissolve in purified water to 5L, and filter through a 0.45 μm microporous membrane. Sugar, operating pressure 1.0 Mpa, operating at room temperature, collecting the nanofiltration concentrate and when the volume of the concentrate reaches 1L, make up the volume to 5L, repeat the operation 3 times, and when the concentrate is enriched to a specific gravity of 1.05-1.10, add 0.95kg wood The sugar alcohol is crystallized, stirred evenly, dried and crystallized at a low temperature of 40°C, and sugar-free brown sugar is obtained.

Embodiment 3

[0029] Embodiment 3: the preparation of sugar-free brown sugar

[0030] Take 1.0 kg of brown sugar, dissolve it in purified water to 5 L, and filter it through a 0.45 μm microporous membrane. Filter the concentrated solution and when the volume of the concentrated solution reaches 1L, make up the volume to 5L, and repeat the operation 3 times. When the concentrated solution is enriched to a specific gravity of 1.05-1.10, add 0.95kg of xylitol crystals, stir evenly, and dry at a low temperature of 40°C. Crystallize to get sugar-free brown sugar.

Abstract

The invention provides a nanofiltration preparation method for removing saccharose in brown sugar. Sugar-free brown sugar developed based on researches of industrial standard of pharmaceutic adjuvant for brown sugar is characterized by a nanofiltration technology. The whole process is free of chemical addition, health-care effective components of brown sugar are retained, and sugar-free brown sugar is prepared, so that the problem of body damage caused by administration of saccharide components for maintenance of diabetics, the aged with hypertension, hyperglycemia and hyperlipidemia or sugar-avoiding young women is solved. In the fields of beautifying and freckle removing, menstruation regulating and blood nourishing and postpartum recovery, the sugar-free brown sugar can replace brown sugar, maintains the taste and curative effect and avoids responses of blood sugar increase and the like induced by administration of sugar. The sugar-free brown sugar can replace common saccharide components as a seasoning for sweet components in kitchen, food and coffee beverages and the like. The quality is controlled by adopting a fingerprinting technology. The sugar-free brown sugar is commonly hard to copy and has a wide application prospect.

Description

technical field [0001] The present invention relates to a sugar-free brown sugar preparation method for removing sucrose in brown sugar by nanofiltration and its application, in particular to a method for removing sucrose in brown sugar by using nanofiltration technology based on the interaction law of component physical and chemical parameters and nanofiltration membrane, which belongs to medicine field. Background technique [0002] Brown sugar refers to the finished sugar of sugar cane with honey, the sugar cane is squeezed and concentrated to form sugar with honey. In addition to the function of sugar, it also contains vitamins and trace elements, such as iron, zinc, manganese, chromium, etc., and its nutritional content is much higher than that of white sugar. From the perspective of traditional Chinese medicine, brown sugar is warm in nature, sweet in taste, and enters the spleen. The effects of nourishing qi and blood, invigorating the spleen and warming the stomach,...
