Abstract
The present invention relates to the processing methods that a kind of microwave assisting method extracts apple skin soluble dietary fiber, belong to technical field of agricultural product process.Contain the substances such as a large amount of dietary fiber, pectin, polyphenol in apple skin, the present invention quickly extracts dietary fiber using microwave assisting method from apple skin, and summary of the invention includes: to take skin, cleaning, drying, it crushes, PH, Microwave Extraction are adjusted, dehydrated alcohol extracts, centrifuge separation, ethanol washing dry, pulverize.
Description
One, technical field
The present invention relates to the processing methods that a kind of microwave assisting method extracts apple skin soluble dietary fiber, belong to food processing skill
Art field.
Two, background technique
China is maximum apple production state and country of consumption in the world, accounts for 40% or so of world's total amount.Apple skin is as by-product
One of object, many abandoneds, or even pollution environment.Containing substances such as a large amount of dietary fiber, pectin, polyphenol in apple skin, but
Due to the limitation of technology, the by-product of apple skin one kind only has small part to be utilized, and the overwhelming majority is still located as waste
Reason is fallen, and the emphasis direction of research will be become by making effective use of the by-products such as apple skin.
Dietary fiber is considered " the 7th kind of nutrient ", and dietary fiber is added in food can increase the health care of food
Property.Microwave loss mechanisms of the present invention extract dietary fiber from apple skin, have the characteristics that transient heating, high conversion, not only greatly
Extraction time is shortened greatly, and heating equipment is simple, cheap, is suitble to large-scale promotion application.
Three, summary of the invention
The object of the present invention is to provide the processing methods that a kind of microwave assisting method extracts apple skin soluble dietary fiber, can be fast
Speed extracts dietary fiber from apple skin, increases the health of food.
The purpose of the present invention is achieved through the following technical solutions:
A kind of processing method that microwave assisting method extracts apple skin soluble dietary fiber, it is characterised in that: it utilizes microwave-assisted
Method quickly extracts dietary fiber from apple skin, comprising: takes skin, cleaning, dries, crush, alkaline process adjusts PH, Microwave Extraction, nothing
Water-ethanol extracts, and centrifuge separation, ethanol washing dry, pulverize.
Further, the alkaline process adjusts PH and refers to: hydrogen peroxide is added in smashed apple skin, adjusts PH to 10,
It impregnates 2 hours.
The Microwave Extraction refers to: the microwave-assisted rapidly extracting dietary fiber of apple skin liquid after alkali process is set micro-
Wave power is 720W, the time 80 seconds.
The dehydrated alcohol extraction refers to: the apple skin liquid that microwave radiation exaraction is crossed will enter 95% second of 4 times of volumes
Alcohol impregnates 30 minutes；Then, it separates, soluble dietary fiber is extracted on upper layer；Lower layer extracts insoluble dietary fiber.
The ethanol washing refers to: lower layer's extract being washed 3 times according to step 5 repeatedly, isolates solubility by several times
Dietary fiber.
Containing the substances such as a large amount of dietary fiber, pectin, polyphenol in apple skin, the present invention using microwave assisting method quickly from
Dietary fiber is extracted in apple skin, summary of the invention includes: to take skin, cleaning, dries, crushes, adjusts PH, Microwave Extraction, anhydrous second
Alcohol extracting, centrifuge separation, ethanol washing dry, pulverize.
Four, specific embodiment
1. taking skin, cleaning fresh apple skin, cleaned in time in 1 hour.
2. drying crushes the apple skin after cleaning, 50 DEG C are dried 8 hours.60 mesh crush.
3. alkaline process, which adjusts PH, is added hydrogen peroxide for smashed apple skin, PH to 10 is adjusted, is impregnated 2 hours.
4. the microwave-assisted rapidly extracting dietary fiber of apple skin liquid after alkali process is set microwave power by Microwave Extraction
For 720W, time 80 seconds.
5. soaked in absolute ethyl alcohol separates the apple skin liquid for crossing microwave radiation exaraction, will enter 95% ethyl alcohol of 4 times of volumes
It impregnates 30 minutes.Then, it separates, soluble dietary fiber is extracted on upper layer；Lower layer extracts insoluble dietary fiber.
Lower layer's extract of step 5 is washed 3 times according to step 5 repeatedly 6. dehydrated alcohol washs repeatedly, is separated by several times
Soluble dietary fiber out.
7. the upper liquid of step 5 and step 6 is crushed to 100 mesh after dry by dry, crushing, soluble dietary fibre is obtained
Dimension.
Claims (5)
1. the processing method that a kind of microwave assisting method extracts apple skin soluble dietary fiber, it is characterised in that: it is auxiliary using microwave
