3. flavor components SPME-GC/MS is analyzed.
The quantitative analysis of volatile ingredient:SPME-GC/MS collection of illustrative plates through computer and manual retrieval each peak simultaneously with NIST Library and Wiley Library match, and retrieval is qualitative, and matching degree and purity are used as qualification result more than 900.Change Compound quantifies:By areas of peak normalization method calculate percentage contents, by volatile flavor substance with the relative of species material Content is added, and compares the difference of all kinds of material relative amounts in the volatile flavor substance of different fermentations liquid.
Single factor analysis using SPME-GC/MS GC-MSs to raisins zymotic fluid culture process, primarily determines that grape Dry fermentation liquid culture process parameter:Wherein raisins proportioning 1:1, solid-liquid ratio 1:4,20 DEG C are cultivated 7 days, and SPME-GC/MS is investigated The amount of volatile flavor substance in zymotic fluid.Shadow of the glucose dosage to flavor substance production is analyzed using SPME-GC/MS Ring, analysis result shows:Sugaring amount is in the range of 2%-6%, C6The content of volatile compound with concentration of glucose increase and Increase when sugaring amount is more than 6%, is unfavorable for the generation of flavor substance, particularly contributes fragrance big aldehydes (referring to Fig. 1) Compound hexanal, the growing amount of trans- 2- hexenoic aldehydes drastically decline (referring to Fig. 2).Obviously, under the experiment condition glucose addition Measure for 6% when it is most suitable.
The influence factor of raisins zymotic fluid culture process is determined with above-mentioned same procedure, as sunlight maiden's grape variety is done Raisins zymotic fluid gross mass is accounted for feed liquid mass ratio, the glucose of elegant love grape variety dry mass ratio, mixing raisins and water Percentage, fermentation time and fermentation temperature.
For example, by taking the dry and elegant love grape variety dry mass ratio of sunlight maiden grape variety as an example, pass through the more gradients of single factor test Experiment is to raisins zymotic fluid culture process parameter setting.Can be by solid-liquid ratio (mixing raisins:Water, g/mL) primarily determine that as 1: 4, sunlight maiden and elegant love raisins proportioning are respectively 1:1,1:2,1:4,1:6,1:When 8,26 DEG C are cultivated 3 days, pass through above-mentioned GC- MS methods investigate the relative amount of zymotic fluid volatile flavor substance, determine the addition of sunlight maiden raisins and elegant love raisins Ratio is 1:1.
2nd, on the basis of the more gradient experiments of above-mentioned single factor test, SPME-GC/MS GC-MSs and Responds Surface Methodology are utilized (Box-Behnken methods) has carried out more optimal analysis to raisins zymotic fluid preparation technology parameter.
According to single factor experiment result, choose volatile flavor substance in fermentation process is had an impact larger four because Element (fermentation temperature, fermentation time, mixes the feed liquid quality of raisins and water than solid-liquid ratio, glucose dosage), utilizes Box- Behnken methods, choose 5 central points and carry out 29 experiments, experimental design is shown in Table 1.Response surface analysis is done to acquired results, should Response surface is with C in zymotic fluid6Volatile compound is response, research fermentation temperature, time, solid-liquid ratio and glucose dosage four Between factor and with C in zymotic fluid6The interactive relation of volatile compound content, and thus draw the optimal work of grape dry fermentation Skill parameter.Grape dry fermentation response surface analysis the results are shown in Table 2, and the results of analysis of variance is shown in Table 3.

The optimal solution of the equation is Y1=5177.98 μ g/L, and each factor is respectively:20 DEG C, time 6.96d of temperature, liquid material Than 4:1, sugaring amount 6%.It is set to 7 days for convenience of the operating time, then the raisins zymotechnique optimized is:Sunlight maiden, elegant love Raisins proportioning is 1:1, solid-liquid ratio 1:4, glucose addition 6%, cultivated 7 days at 20 DEG C.
3rd, raisins hair is carried out according to the optimal raisins zymotic fluid culture process parameter of optimization gained in above-mentioned one and two The preparation of zymotic fluid.
(1) after the dry and elegant love grape variety xeromenia of sunlight maiden grape variety being chosen into impurity elimination, by sunlight maiden's kind Portugal Grape do:Show love grape variety is done as 1:1 mass ratio carries out being mixed to get mixing raisins;
(2) it is 1 by the feed liquid mass ratio of mixing raisins and water:4 weigh respectively mixing raisins and water it is standby;By accounting for Stating the amount of raisins zymotic fluid gross mass 6%, to weigh glucose standby;
(3) fermentation tank is cleaned with clear water, will after using 75% edible alcohol to sterilize and dry again after drying (2) in the water injection fermentation tank weighed in, and the glucose is added to the water while stirring, after glucose fully dissolves, Add the mixing grape dry doubling to stir, then seal the fermentation tank;
(4) fermentation temperature is 20 DEG C in fermentation tank described in holding (3), and raisins zymotic fluid is obtained after being sealed by fermentation 7 days.
4th, the raisins zymotic fluid obtained by being prepared in three is as flavor sweetening agent and yeast supplement application in making water Fruit flavor bread.
Because the purposes of raisins zymotic fluid is lifting bread fragrance, so the zymotic fluid of culture wants high-temperature baking resistant, pass through Still excellent fragrance can be provided after high-temperature baking for bread, so we are divided fruit zymotic fluid using baking test Analysis, multi-angle checking zymotechnique optimized parameter.
The preparation method of the flavor bread is as described below:Weigh bread flour, yeast, white granulated sugar, salt and water;By a part Water dissolves yeast, remaining water dissolved sugar and salt;Flour is poured into a mixing bowl, adds flour, dissolves the water of yeast, dissolves white sand The water of sugar and salt;Stirring;The dough being stirred is stood into 15min at room temperature;The dough stood is split and rubs circle with the hands, 50g/;Relaxation, shaping;In the 85% time fermentation of 38 DEG C of temperature and humidity;Toasted under conditions of excessive internal heat/lower 190/200 DEG C of fire 14min;Then cool down and pack.The dispensing of the flavor bread is (weight/g), bread flour 100, yeast 4, white granulated sugar 2, salt 2, fruit zymotic fluid and water can be according to 1:0,1:1,1:2,1:3,1:4 ratios are added.
When using SPME-GC/MS GC-MSs to preparing bread using raisins zymotic fluid in the present embodiment, raisins hair Zymotic fluid dosage is analyzed bread flavor effect, and wherein bread flavor material still uses foregoing C6Alcohols and C6Aldehydes chemical combination Thing.
1.GC/MS bread flavor material bread preprocess methods:Bread core is divided into about 5mm × 5mm × 3mm's is broken Piece, it is put into 15mlSPME sample bottles, sample accounts for the 3/5 of bottle volume, covers bottle cap, and sample bottle is put into 60 DEG C of thermostatted waters In bath, the good extracting head of aging is inserted into sample bottle overhead, headspace extraction 40min, fiber head is returned in syringe needle with handle, Extract syringe needle sample introduction.
2. it can refer to the method for GC/MS analysis bread flavor materials foregoing using SPME-GC/MS analysis zymotic fluid flavors Method.Zymotic fluid is 1 with water adding proportion:0,1:1,1:2,1:3,1:When 4, fermented dough, bake, analyzed by using GC/MS Finished product bread flavor content of material, although from figs. 3 and 4 it can be seen that zymotic fluid and water adding proportion are 1:C6 in bread when 1 Compounds content highest, but the acid ingredient in zymotic fluid, the opposite if the too high levels of the acids such as tartaric acid, acetic acid Bag flavor adversely affects.
Bread sensory evaluation is right with reference to People's Republic of China's baking quality standards of grading (GB/T 14611-2008) Bread is evaluated, and evaluation result is shown in Table 4.
Table 4
From the results shown in Table 4, zymotic fluid and water are with 1:2 additions, compared with the addition of other ratios in bread, The flavor that raisins zymotic fluid can obviously improve bread is added in breadmaking, wherein zymotic fluid and water is with 1:2 ratios are added Shi Xiaoguo is particularly evident.Therefore consider, zymotic fluid and water adding proportion are defined as 1:2.
Example two:
Conventional method is typically to use single factor test, and more gradient tests determine the technological parameter of flavor fruit zymotic fluid, selection The factor having a great influence is analyzed flavor fruit zymotic fluid including temperature, time, solid-liquid ratio, sugaring amount, the present embodiment Only it is defined as example from technological parameter, illustrates single factor test, more gradient tests determine the analysis method of flavor fruit zymotic fluid, Specific steps:
In the case where other conditions (temperature, solid-liquid ratio, sugaring amount) are constant, using solid-liquid ratio 1:4, raisins proportioning 1: 1,1,2,3,4,5,6,7,8,9,10d is cultivated respectively at 18 DEG C.The change of total acid, pH in fermentation process is detected, GC-MS is investigated The amount of zymotic fluid volatile flavor substance.
Caused appropriate acid ingredient in fermentation process, such as tartaric acid, acetic acid have improvement result, mistake to bread flavor Degree is then on the contrary, it is therefore desirable to the total acid to zymotic fluid, pH to be controlled by.With the progress of fermentation it can be seen from Fig. 5, The pH of zymotic fluid is reduced, and total acidity increase, is tended to be steady to zymotic fluid pH at the 9th day, and the increase of total acidity also starts to slow down.
Fig. 6 shows that fermented and cultured to the 7th day C6 volatile compound content reaches maximum, is then held essentially constant.So And as shown in Figure 7, ferment to 8-10 days, although C6 volatile compound total amounts do not have a significant change, taste threshold compared with Low, the content for contributing big hexanal, trans- 2- hexenoic aldehydes to fragrance drastically declines, and fragrance value is less except hexanol keeps constant Outside, cis- 3- hexenols, trans- 2- hexenes alcohol content significantly improve.Therefore after fermenting more than 6 days, fermentation liquid acidity increases Add obvious, volatile flavor component loss is larger, therefore fermented and cultured 6 days is more suitable.
The factor of influence flavor fruit zymotic fluid is determined in the same way, such as:The fermentation temperature of flavor fruit zymotic fluid, material The index such as liquor ratio, glucose addition.
In the case where other conditions (temperature, solid-liquid ratio, sugaring amount) are constant, using solid-liquid ratio 1:4, raisins proportioning 1: 1, respectively to cultivate 1,3,6,9d making zymotic fluid bread at 18 DEG C, A, B, C, D are respectively labeled as, and carry out sensory evaluation. The evaluation result obtained according to single factor analysis method, it is determined that being cultivated 6 days at 18 DEG C, zymotic fluid flavor is best.
Breadmaking step is with described in example one kind, and bread sensory evaluation is with reference to People's Republic of China's baking quality Standards of grading (GB/T 14611-2008) are evaluated bread, and evaluation result is shown in Table 5.
