Description
Technical field
The present invention relates to a kind of methods for judging casing crosslinking degree, belong to casing technical field.
Background technology
At present, backend application experiment is also overly dependent upon for the detection of Collagent casing for sausages, the detection of casing finished product is also
The purpose of prediction application situation is unable to reach, and the detection applied is not only of high cost, efficiency is low, but also using testing result
Presentation is relatively single, and most problems in production can all influence application test testing result.
The main contributor of casing application problem is that the crosslinking of casing is not complete enough, at present can not also be accurate for the detection of casing
True judges whether casing crosslinking degree is completed.In detection usually, chancing on part casing can be torn into inside and outside two layers, and
And the casing that can be torn from centre has relatively high ratio various exceptions occur in application process.Analyze reason, casing into
Crosslinking agent can be added dropwise from outer layer during type, crosslinking agent is contacted directly with casing tube wall outer layer, and surface friendship can be blown away in next procedure
Join agent, it, can be from for the judgement of the crosslinking degree of casing it is inferred that the phenomenon that casing differs there may be interior external crosslinking situation
Crosslinking inside and outside casing carries out respectively.
Report is specialized in currently without to external crosslinking testing result in casing, it is whole all from casing to the detection of casing
Set about, have ignored crosslinked difference inside and outside casing.
The content of the invention
It is an object of the invention to provide it is a kind of judge casing crosslinking degree method, it is scientific and reasonable, it is easy to operate just
Victory compensates for the vacancy of casing crosslinking degree detection method, and more accurate prediction is carried out to the practical application of casing, while can
Guidance is provided for the adjustment direction of production technology.
The method of the present invention for judging casing crosslinking degree, comprises the following steps：
(1) finished product sausage casing sleeve is cut off vertically, forms casing thin slice；
(2) casing thin slice from centre is torn, be divided into two layers inside and outside；
(3) two layers of thickness and hot acid inside and outside casing are measured respectively and resists disconnected power, and hot acid resists disconnected power with the numerical value of unit thickness
As report result；
(4) respectively to two layers of progress microscopy inside and outside casing, the difference of two layers of fibre diameter inside and outside comparison；
(5) result drawn according to step (3) and (4) judges, for casing ectonexine thickness ratio is big, hot acid resist it is disconnected
Force difference is different big and fibre diameter difference is big, is judged as that casing crosslinking is not thorough.
The length of the finished product sausage casing sleeve is 14-18m.
Specific measuring method is as follows：
1st, thickness ratio detects：Thickness inside and outside casing is measured using micrometer caliper (micrometer), casing is torn into
Fillet of the width for 2mm or so is cut into after inside and outside two layers, thickness is measured using micrometer caliper, takes the average value of 5 Duplicate Samples
As a result.Thickness ratio=outer layer thickness/internal layer thickness * 100%, thickness ratio regards as thickness outside 70%-130% scopes
Than big.
2nd, hot acid resists disconnected power to detect：Ectonexine casing is cut into 1.5cm wide, about 20cm long, each sample cuts four
It is spare, water-bath pot temperature is adjusted to 70-80 DEG C, and about 50ml 0.1mol/L hydrochloric acid is taken to be put into insert in water-bath in beaker and heat,
Start to test when hydrochloric acid temperature stabilization is at 70 ± 2 DEG C.Puller system specimen length is adjusted to 100mm, and casing is immersed in hydrochloric acid 1 point
Clock, taking-up blot surface hydrochloric acid with filter paper, carry out tensile test, record test number, calculate average value.Hot acid resist disconnected power ratio=
Outer layer hot acid resists disconnected power/internal layer hot acid to resist disconnected power * 100%, and hot acid resists disconnected power ratio to regard as heat outside 80%-120% scopes
The anti-disconnected force difference of acid is different big.
3rd, fibre diameter is than detection：It is right respectively using the microscope for being equipped with imaging system (bright U.S.'s microscopy imaging system)
Ectonexine casing carries out microscopy under 10 times of eyepieces, 4 times of object lens, uses the internal outer layer fiber thickness diameter of scale in imaging system
It measures, chooses 5 Duplicate Samples as experimental result.Fibre diameter ratio=outer layer diameter/internal layer diameter * 100%, diameter ratio
It is big that fibre diameter difference is regarded as outside 80%-120% scopes.
It is found by detection, casing ectonexine thickness ratio, ectonexine hot acid resist disconnected power and microscopy result with higher
Uniformity, ectonexine testing result difference it is higher can determine whether to be not thorough for external crosslinking in casing, so as to judge the crosslinking of casing
It is not thorough.When the result of three of the above parameter occur criterion it is inconsistent when, the sequencing judged resists disconnected power ratio as hot acid
＞ thickness ratio ＞ fibre diameter ratios.
According to a large number of experiments experience, collagen its inside and outside thickness ratio easily torn from centre is higher, and its ectonexine
Hot acid resists disconnected power also to have larger difference, compares a large amount of detection data, and the hot acid of its internal layer unit thickness of the high casing of thickness ratio resists
Disconnected power is relatively low.It is bright to find that thickness ratio is high, hot acid resists the different big casing ectonexine of disconnected force difference also to have on fibre diameter by microscopy
Significant difference is different, and for the fibre diameter of internal layer higher than outer layer, this phenomenon, which can be crosslinked to be not thorough with internal layer, causes collagenous fibres water absorption rate high
To explain.
Compared with prior art, the present invention it has the advantages that：
The present invention detects the crosslinking of casing ectonexine respectively by the integrated use of a variety of detection means, scientific and reasonable,
Simple and convenient, the vacancy of casing crosslinking degree detection method before compensating for carries out subject to more the practical application of casing
True prediction, while guidance can be provided for the adjustment direction of production technology.
Specific embodiment
With reference to embodiment, the present invention is further illustrated, but it is not intended to limit the implementation of the present invention.
Embodiment 1-3
(1) the finished product sausage casing sleeve of 14-18m is cut off vertically, forms casing thin slice；
(2) casing thin slice from centre is torn, be divided into two layers inside and outside；
(3) two layers of thickness and hot acid inside and outside casing are measured respectively and resists disconnected power, and hot acid resists disconnected power with the numerical value of unit thickness
As report result；
(4) respectively to two layers of progress microscopy inside and outside casing, the difference of two layers of fibre diameter inside and outside comparison；
(5) result drawn according to step (3) and (4) judges, for casing ectonexine thickness ratio is big, hot acid resist it is disconnected
Force difference is different big and fibre diameter difference is big, is judged as that casing crosslinking is not thorough.
Specific measuring method is as follows：
