The sample of different disposal group is measured with fast tester for water content, the moisture of 9 groups of samples is drawn respectively
As a result (8 are shown in Table).As shown in Table 8, the moisture with comparison shrimp in jelly of different sodium bicarbonate, egg white and starch affects not
Greatly, the otherness of 9 groups of sample rooms is less.But can be seen that the moisture and sensory evaluation scores of sample by the correlation analysis of table 9
Negative correlation is presented, it is known that the moisture of peeled shrimp returns to a certain extent that to have influence on its organoleptic quality, i.e. moisture higher,
The sensory evaluation scores of peeled shrimp sample are lower, then mouthfeel is better.It is cold after why to each other significant difference may be less likely to starching
The factors such as Tibetan time, peeled shrimp raw material have compared with Important Relations, therefore the correlation between moisture and shrimp in jelly organoleptic quality is in
Existing larger relevance.

So showing that the optimum proportioning of shrimp in jelly starching is in Fuzzy Comprehensive Evaluation system anlysis result:Sodium bicarbonate
1%, egg white 3%, starch 3%, the i.e. sodium bicarbonate of 1 weight portion, the egg white of 3 weight portions, the starch of 3 weight portions.Peeled shrimp finished product is brilliant
Jade-like stone is exquisitely carved, and slurries parcel is uniform, body is complete, pleasant to the palate after entrance, resilient enough.
Embodiment 2
Peeled shrimp carries out starching after thawing, rinsing, dry, and slurries are sodium bicarbonate, the eggs of 3 weight portions by 1 weight portion
Clearly, the starch of 3 weight portions, the sugar of 1 weight portion, the salt of 1 weight portion, the salad oil of 2 weight portions are allocated and made jointly, upper complete slurry
Peeled shrimp is placed in 4 DEG C of refrigerator cold-storages (setting 0,30,60,90min groups).Peeled shrimp after refrigeration oil 40s excessively under 130 DEG C of oil temperature,
Take the dish out of the pot and drain;Pour soup-stock into and boiling is heated in clean pot, pour into and drip oily peeled shrimp 1min is cooked together with soup-stock
Take the dish out of the pot.
Wherein soup-stock is allocated as:Wherein soup-stock is allocated as:The monosodium glutamate of 0.3 weight portion, the cooking wine of 3 weight portions, 3 weight
The green onion, ginger and garlic mixture, the starch of 2 weight portions, the water of 60 weight portions of part, stirs, in the green onion, ginger and garlic mixture, green onion ginger
Garlic mass ratio is 1:1:1.
Selected on most suitable by the measure to shrimp in jelly peeled shrimp sensory evaluation, TVB-N and makings composition
The slurry time.
(1) fuzzy mathematics sensory evaluation score (selecting 10 people as assessment officer), makes a concrete analysis of as follows:
Set of factors U, evaluation language collection V, the determination of weight sets K are with embodiment 1.
A) foundation of fuzzy evaluating matrix and result
Choose 10 subjective appreciation persons to 4 groups of samples according to shrimp in jelly color and luster, fragrance, flavour, 4 factors of quality
Evaluate one by one, corresponding grade poll distribution situation is shown in Table 3.By each grade number of votes obtained folding of the qualitative factor of each sample in table 3
Favorable ratio is counted as, with reference to the evaluation result of all factors of each sample, fuzzy matrix Aj is obtained.J-th sample it is fuzzy
Matrix is:
Wherein:J=1,2,3,4 (respectively correspond to 0,30,60,90min) be sample number into spectrum, i=1,2,3,4 is quality evaluation
Factor, what ri1, ri2, ri3 were respectively each opinion rating number of votes obtained of i-th factor of evaluation agrees with ratio.
As shown in Table 3:The fuzzy matrix of 1~No. 4 sample is as follows:
B) blurring mapping and comprehensive evaluation result
According to fuzzy matrix transformation principle:R=K × A, then be R to jth sample evaluation resultj=K × Aj, with the 1st group
Comprehensive evaluation result as a example by sample is:
The shrimp in jelly of the gained under the 0min starching times is these results suggest that, the subjective appreciation person for having 26.3% thinks excellent
Show, 54.3% thinks general, and 19.4% thinks poor.The comprehensive evaluation result of other samples can be obtained in the same manner:R2=(0.586,
0.388,0.026);R3=(0.479,0.469,0.052);R4=(0.493,0.447,0.026);
Outstanding to agree with ratio bigger from the point of view of analysis result, then the fuzzy mathematics sensory evaluation scores of the flavor taste of sample are got over
Height, then the quality of peeled shrimp is better.It can be seen from the results above that No. 2 the outstanding of sample agree with ratio to be maximum, reach
58.6%, the subjective appreciation person for illustrating 58.6% gives outstanding evaluation to No. 2 samples, has exceeded the product of other numberings,
And outstanding to agree with ratio to reach 97.4% with ratio summation is typically agreed with, most people compare No. 2 samples of acceptance, and root
According to maximum subjection principle, it can be assumed that No. 2 sample integrated sensories are optimal, then in sensory evaluation come say the slurry time for 30min when
It is that most suitable, mouthfeel is optimal.
Shrimp in jelly subjective appreciation poll distribution under the conditions of the different sizing techniques of table 10
Note:v1:It is outstanding;v2:Typically:v3;It is poor
The integrated ordered result of the shrimp in jelly sensory evaluation of table 11
(2) measure of TVB-N (VBN)
The starching time is 44.52mg/100g for the shrimp in jelly TVB-N contents of 0min, and with the increase of starching time,
The TVB-N contents of sample are gradually increasing, and when having arrived 60min, the content of TVB-N has reached 61.94mg/100g, subsequently gradually becomes
In gentle.Because raw material uses freezing shrimp meat, even if so the starching time is 0min, the TVB-N contents of sample are also higher,
In time period from 0min to 60min, the TVB-N contents of peeled shrimp significantly rise, and this may have with the effect of the egg white in slurries
Close, under the decomposition of sodium bicarbonate, in peeled shrimp muscle and egg white protein simultaneously all decomposing, so upper by the initial stage,
The content of TVB-N continues to increase, and when having arrived 90min, decomposition tends to be steady.So when the starching time being 30min, by
Shrimp in jelly VBN is lower made by freezing shrimp meat, and nutritive value is higher.
C) GC-MS analyses
As shown in table 5, GC-MS has altogether to be separated from shrimp in jelly and identifies 46 volatile ingredients, respectively alcohols (5
Kind), aldehydes (2 kinds), ketone (2 kinds), alkane alkene (3 kinds), aromatic hydrocarbon (21 kinds), lipid (4 kinds), other classes (9 kinds), detection
All kinds of volatile compounds in, the content highest of hydrocarbon compound, especially aromatic hydrocarbon material.
With the increase of starching time, the flavor substance of sample alcohols, aldehydes and ketone gradually increases, during this is with peeled shrimp
Fat oxidation is relevant.Ketone compounds give the shrimp fragrance of a flower and fruital local flavor, and lipoid substance is normally due to lipid-metabolism production
Carboxylic acid and alcohol esterification product, the meat of shrimp be characterized with important local flavor contribution.As shown in Table 13, with starching
The prolongation of time, the ratio that the lipid material of shrimp in jelly is shared in all flavor substances gradually rises, and illustrates starching to water
The local flavor of brilliant peeled shrimp has important impact.But meanwhile, the material of other classes with the increase of starching time, proportion also by
Gradually rise, in other materials, be mostly sulphur amine substance, prawn meat flavor has dysgenic.So from flavor substance point
From the point of view of analysis, local flavor important of the slashing step to shrimp in jelly, but starching overlong time can't proportionally optimize
The quality of peeled shrimp, the reason for this has also confirmed the shrimp in jelly highest scoring of starching 30min in sensory evaluation.
Shrimp in jelly volatile flavor component analysis result (n=3) (μ g/g) of table 12
All kinds of flavor substance proportions of table 13
Substance classes | 0min | 30min | 60min | 90min |
Alcohols (%) | 15.66 | 30.05 | 33.71 | 9.48 |
Aldehydes (%) | 0 | 0.23 | 2.18 | 1.5 |
Ketone (%) | 0 | 0.14 | 0.14 | 0 |
Alkane alkene (%) | 9.06 | 3.28 | 4.09 | 4.18 |
Aromatic hydrocarbon (%) | 69.53 | 35.56 | 40.42 | 45.07 |
Lipid (%) | 0.92 | 3.02 | 6.66 | 9.73 |
Other classes (%) | 4.83 | 2.7 | 12.8 | 30.04 |
So by sensory evaluation and indices analysis as can be seen that shrimp in jelly starching time under the conditions of 4 DEG C is
The integrated quality of peeled shrimp more preferably, and can greatly save the starching time by Experimental Research during 30min, be conducive to industrial
Exploitation.
