Abstract
The invention discloses a kind of methods of impurity in detection soybean separation protein white powder, weigh 15g soybean separation protein white powder, 4g liquid alkaline, 500 ± 5g water is put into plastic beaker, it is stirred 2~3 minutes with glass bar, until albumen is dissolved completely in buck, protein liquid after stirring is stood 10 minutes, then protein liquid is poured into and is put well on the funnel of impurity plate in advance, and it is filtered with vacuum pump to impurity plate no liquid, then funnel is poured into 500 ± 5g water rinse impurity plate, it is filtered with vacuum pump always in flushing process, then the impurity plate after cleaning 65 DEG C of baking oven are put into dry 15 minutes, dry the moisture on impurity plate, weigh the weight of impurity plate, calculate the weight change of impurity plate filtering front and back, judge whether workshop is out of control to the control measure of impurity in product according to weight change.Detection method detection time of the present invention is short, result is accurate, has directiveness to Workshop Production.
Description
Technical field
The present invention relates to the detection fields of soybean impurity, more particularly to impurity in a kind of detection soybean separation protein white powder
Method.
Background technique
Soybean protein isolate is a kind of full-price protein food additive produced using low temperature desolventizing Soybean Meal as raw material, greatly
For protein content 90% or more, amino acid classes have nearly 20 kinds, and contain essential amino acid in beans protein isolate, battalion
It supports and enriches, it is cholesterol-free, it is one of the kind of alternative animal protein few in number in vegetable protein.Because of soybean separation protein
White have very high nutritive value is widely used in food with good functionality, therefore soybean separation protein white powder is to impurity
Content has stringent index, and plant process controls the impurity in soybean separation protein white powder layer by layer, but workshop is to impurity
Whether control measure are effective, need finally to be verified by finished product detection, and how to verify soybean impurity is to judge that soybean separates
The effective ways of index, it is therefore desirable to which a kind of detection method of impurity is realized.
Summary of the invention
The object of the invention is that verifying and being controlled in production process to quickly detect the impurity in soybean separation protein white powder
The validity of impurity workshop section processed and in a kind of detection soybean separation protein white powder for providing impurity method.
The present invention through the following technical solutions to achieve the above objectives:
A kind of method of impurity in detection soybean separation protein white powder, comprising the following steps:
Step 1: stand-by filtering board of impurity is weighed, weight is denoted as m1 first in 65 DEG C of baking 10min of baking oven；
It is poured into plastic beaker Step 2: weighing water 495g, then weighs 15 grams of soybean separation protein white powder for needing to detect, claimed
Liquid alkaline 4g is taken, plastic beaker is placed in, protein isolate, liquid alkaline, water are stirred into 2min with glass bar, until albumen is dissolved completely in alkali
In water, then static placement 10min.
Step 3: drying, weighed filtering board of impurity are placed on the Buchner funnel on bottle,suction in advance, wait stir
It mixes liquid to place after ten minutes, opens vacuum pump, protein liquid is poured into bottle,suction by filtering board of impurity, until crossing impurity
The smoke filtrate of filter plate is spent in one after another drop of filtering, then is filtered 30 seconds；
Step 4: 495g water is then poured into bottle,suction by filtering board of impurity, to the albumen on filtering board of impurity
Residual is cleaned, and until the smoke filtrate of filtering board of impurity is in one after another drop of filtering, then is filtered 30 seconds, is closed vacuum pump；
Step 5: the filtering board of impurity cleaned in funnel is put into 65 DEG C of baking 30min of baking oven, weigh, weight note
For m2；
Step 6: calculating m2-m1, judge whether workshop is effective to the control workshop section of impurity according to testing result.
Further, the liquid alkaline concentration in step 2 is 30-32%, conductivity≤150us/cm of the water, institute
The diameter for stating filtering board of impurity is 34mm, and the plastic beaker is 1000ml.
Further, the diameter of Buchner funnel described in step 3 is 33mm.
Further, liquid alkaline (NaOH) selected in detection can be replaced potassium hydroxide (KOH) or calcium hydroxide (Ca
(OH)2) one kind.
Protein dissolution, is passed through leakage by the principle that the present invention utilizes soybean protein isolate to dissolve in alkaline condition in liquid alkaline
Bucket filters, and if there is undissolved impurity in soybean protein, residual can be left on impurity plate after protein solution filtering, according to miscellaneous
Remaining amount judges whether the workshop section of Shop floor control impurity is effective on scutum, and impurity plate selected by the present invention is impurity degree
Filter plate causes weight in akaline liquid not have loss, and detection time is short, result is accurate, has to Workshop Production and refers to
The property led.
Specific embodiment
Below with reference to embodiment and comparative example, the invention will be further described:
