Main target currently, with respect to water soluble dietary fiber Study on Preparation is to combine biological method and chemistry, thing
Reason method, more reasonably utilizes raw material, reduces the waste discharge in production process.The existing water soluble dietary fiber prepared
Method has following several:
Physical method.Predominantly extrusion cooking method.Under high temperature, high pressure conditions, high microsteping material stability and local flavor are bright
Aobvious improving, under violent extruding condition, the water-soluble component of dietary fiber increases, but obtain is water solublity and insoluble fibre
Mixture.And this method has an obvious shortcoming when extraction has bioactive product, it is simply that to heat sensitive one-tenth
Dividing and inapplicable, the long-time extraction under high temperature is unfavorable for heat sensitive bioactive compound, causes high energy consumption, low output
Result.
Chemical method.Use organic reagent, by chemical reactions such as acid-base reactions, make dietary fiber carboxy methylation, strengthen
Its water solublity, but the method is easily caused environmental pollution.
Membrane separation process.Utilize high-tech membrane separation technique, the dietary fiber of different molecular weight is separated, it is to avoid chemistry point
From organic residue, water soluble dietary fiber has greatly prospect.
Chemical reagent and enzyme combine extraction method.After the pretreatment of chemical reagent, with α-amylase, protease, saccharifying
Other impurity of degraded such as enzyme and cellulase, then process with organic solvent, it is thus achieved that the water soluble dietary fiber that purity is higher.But enzyme
Rush method also exists deficiency with high costs, that the response time is long.
Fermentation method.With Lactobacillus bulgaricus and streptococcus thermophilus, raw material is fermented, be then washed to neutrality, be dried
After obtain dietary fiber, be mainly used in peel raw material and prepare dietary fiber.
The shortcoming existed except said method, is modified dietary fiber, improves the yield of water soluble dietary fiber also
Become research emphasis.Modification makes the connecting key of macromole rupture, and makes insoluble component be changed into soluble component, improves meals
The retention ability of food fiber and adsorption, preferably play the physiological function of dietary fiber.The functional character of dietary fiber and meals
The content of the food retention ability of fiber, swelling degree and water soluble dietary fiber has the biggest relation.Prepare dietary fiber general
Method is to soak with acid or alkali, then washes with water to neutrality, owing to washing repeatedly can reduce the retention ability of dietary fiber and swollen
Expansibility, will also result in the loss of water soluble dietary fiber simultaneously, and these processing are all unfavorable for keeping the functional character of dietary fiber,
And the content of water soluble dietary fiber is the lowest in natural dietary fiber, the most how to reduce the step of washing and improve meals
In fiber, the content of water soluble dietary fiber is the focus of research.
Fructus Canarii albi can produce a large amount of Fructus Canarii albi slag in the course of processing, and preliminary study finds, has abundant function in Fructus Canarii albi slag
Property composition, based on dietary fiber, dry weight total content be higher than 80%, if exploitation is used, can turn waste into wealth, creation can not
The economic worth estimated, brings huge social benefit.Therefore, a kind of Fructus Canarii albi solubility efficient, easy, low cost is probed into fine
Dimension preparation method has important practical significance.
