Abstract
The invention discloses a process method for extracting pectin from sugar beet pulp, wherein the process method comprises the following steps: washing the sugar beet pulp with hot water for 2-3 times, sprinkling with ethyl alcohol, taking out and drying in the air; crushing the sugar beet pulp after drying into the particle size of 0.1-0.5 mm; adding distilled water, adjusting the pH to 1.8-2.2 with hydrochloric acid, and heating to boil for 10 min; putting into a constant-temperature water bath, hydrolyzing for 8-10 h at the temperature of 60-80 DEG C and continuously stirring; after the hydrolysis is completed, removing moisture with a cooking method, carrying out suction filtration and squeezing of the residual paste, and still maintaining the pH value at 3-4; carrying out heat-preservation stirring and filtration at the temperature of 70 DEG C, and concentrating the filtrate in vacuum at the temperature of 60 DEG C to the volume 1/5-1/4 of the original volume; and precipitating with edible alcohol, filtering out pectin, carrying out suction filtration, washing with ethyl alcohol, drying and crushing, and packing to obtain the product. The method is simple and reliable, non-toxic chemicals in the whole process are adopted, and the obtained product is safe and reliable and has high quality.
Description
Technical field
The present invention relates to the technical field of comprehensive utilization of Radix Betae, specifically a kind of process extracting pectin from megasse.
Background technology
Megasse is the side-product of sugaring, is beet root, tuber residue after immersion, squeezing extraction sugar liquid, therefore in residue, water-fast material exists in a large number, and particularly crude fibre all retains.Megasse is the succulent fodder that domestic animal is good, and female animal is also had galgctogogue action, is used for feeding cattle, megasse be mainly composed of soluble N-free thing, and protein and fat are little, and calcic is extremely many, phosphorous few, palatability is strong, and more containing crude fibre, water content accounts for 85%, can not long storage periods, can storing after drying, dried chips volume is big, has soft stool, main component is nitrogen-free extract and crude fibre, and thick protein accounts for 9.6%.But megasse also contains a lot of macromolecule saccharide, namely pectin is former, the mixture of pectic acid and pectic substance, pectin can be extracted by garden beet slag, if megasse is solely for animal and fowl fodder, it is not intended as huge waste, therefore, research and develop a kind of process utilizing megasse to extract pectin and the deep processing and utilization of megasse is had significantly high economic worth.
Summary of the invention
The purpose of the present invention is aiming at current megasse and is generally used as animal and fowl fodder use, and pectin contained therein is wasted in a large number, it does not have the problem being integrated into utilizing, it is provided that a kind of process extracting pectin from megasse.
A kind of process extracting pectin from megasse of the present invention, it is made up of following step: megasse is put in container with after hot wash 2-3 time, take out after spilling ethanol and dry, it is 0.1-0.5mm that dried megasse is crushed to particle diameter again, it is reentered in container, add distilled water, with hydrochloric acid, pH is modulated 1.8-2.2, heated and boiled 10min, put in water bath with thermostatic control, 8-10h it is hydrolyzed at 60-80 DEG C, and be constantly stirred, moisture therein is removed with cooking process after hydrolysis, remaining paste sucking filtration after anhydrating, squeezing, and remain that pH value is between 3-4, insulated and stirred at 70 DEG C, filter, filtrate vacuum at 60 DEG C of temperature is concentrated into the 1/5-1/4 of original volume, precipitated with edible ethanol, leach pectin and carry out sucking filtration, last again by washing with alcohol, dry, pulverize, pack.
The inventive method is to utilize three kinds of macromolecule saccharides contained in megasse, namely pectin is former, the mixture of pectic acid and pectic substance, pectic substance and pectic acid are water-soluble substanceses, enter in water through water soaking, and the calcium and magnesium salt of the former galactan aldehydic acid being partial methylation of pectin, though it is water insoluble, but when olefin(e) acid, generation pectic acid and methanol can be hydrolyzed and enter in water through decolour, anhydrating, after the process such as sucking filtration, pectin therein is made to be precipitated with ethanol, processing through washing with alcohol, drying etc. after, get product pectin.
The inventive method technique is simple, and whole process all uses nontoxic chemical substance, and products obtained therefrom is safe and reliable, and quality is high, has good economic benefit and social benefit.
Detailed description of the invention
Embodiment 1
A kind of process extracting pectin from megasse, it is made up of following step: megasse is put in container with after hot wash 3 times, take out after spilling ethanol and dry, it is 0.2mm that dried megasse is crushed to particle diameter again, it is reentered in container, add distilled water, with hydrochloric acid, pH is modulated 2.0, heated and boiled 10min, put in water bath with thermostatic control, 10h it is hydrolyzed at 70 DEG C, and be constantly stirred, moisture therein is removed with cooking process after hydrolysis, remaining paste sucking filtration after anhydrating, squeezing, and remain that pH value is between 3.5, insulated and stirred at 70 DEG C, filter, filtrate vacuum at 60 DEG C of temperature is concentrated into the 1/5 of original volume, precipitated with edible ethanol, leach pectin and carry out sucking filtration, last again by washing with alcohol, dry, pulverize, pack.
