Description
Technical Field
The invention belongs to the technical field of mackerel processing, and particularly relates to a salt-reducing and freshness-increasing preparation process for dry-cured mackerel.
Background
Spanish mackerel belongs to the family Perciformes, the family Spanish mackerel (family Tinopectaceae), the body is long and flat, the body color is silvery, the back has dark stripes or black blue spots, the mouth is large, the cuspid is sharp, the teeth are sharp, the swimming is rapid, the sexual condition is fierce, the general body length is 260-520 mm, the size of the large person can reach more than 1m and the weight is more than 20kg, and the mackerel is are distributed in the western region of the North Pacific ocean, the east China sea, the yellow sea and the Bohai sea. The main fishing ground includes Zhoushan, Lianhong open sea and Shandong south coast. Belongs to the middle and upper layer fishes in warm water, and often colonizes for long-distance migration. The growth is rapid, the length of the fork of the young fish in the current year can be 25-30 cm, the average fork length of the 1-2 instar fish is 50cm, and the average weight is about 800 g.
Spanish mackerel meat is more and less in thorn, tender in meat and delicious in taste; the reputations of Shanshang Francolini river-river and Heimi Spanish are in folk. The edible method is various, and the food can be eaten fresh or pickled. The mackerel pickling can be divided into dry pickling and wet pickling. The wet pickling refers to pickling the fish in a pickling solution. The dry pickling is a process of pickling by using dry salt (crystal salt) or mixed salt, firstly wiping the surface of the food thoroughly to cause the food to have the phenomenon of outward permeation of juice (the fish is pickled without wiping thoroughly), and forming salt liquid by means of the outward permeation of juice. Since salt is added only and no water is added during pickling, the method is called dry pickling.
However, the inventor finds that the dry-cured mackerel obtained by the conventional dry-curing method has the following defects in the process of dry-curing mackerel:
(1) the content of fresh amino acid in the dry-cured mackerel is low, so that the dry-cured mackerel has insufficient fresh taste; (2) the dry-cured mackerel has low content of sweet amino acids, which causes insufficient sweet taste of the dry-cured mackerel; (3) the dry-cured mackerel obtained by the traditional dry curing method has higher hardness, stickiness and chewiness, and the texture and sense of the dry-cured mackerel are seriously influenced; (4) the traditional dry pickling method needs to add more salt to inhibit the growth and the propagation of microorganisms, otherwise, the safety and the texture sense of the product are affected; (5) the traditional salt reduction method is adopted, for example, the addition of substitute salt (potassium chloride, calcium chloride and the like) can generate certain undesirable taste such as metallic taste, astringent taste and the like to mackerel.
The technical problems can greatly influence the quality and the taste of fish meat, and can generate bad flavor and destroy the nutritive value of the fish meat. Therefore, the dry pickling method for the mackerel is rich in fresh amino acid content and/or rich in sweet amino acid content and/or low in hardness, stickiness and chewiness and capable of reducing the salt consumption, and has important significance for improving the quality of the dry pickled mackerel.

Experimental example 1 evaluation of taste of dry-cured Spanish mackerel of example 1
The pieces of the dry-cured mackerel prepared in experimental example 1 were boiled in water for 15min, and then a sensory evaluation group was composed of 13 persons, and the taste of the boiled dry-cured mackerel was evaluated from 5 points of umami, salty, thick, sweet, and bitter. The test was scored using a score of 10 and all results averaged. Each panelist, independently scored, and each tasted one sample, rinsed with distilled water, and then tasted the next sample.
In order to determine the basic taste characteristics of the dry-cured mackerel, the dry-cured mackerel is steamed over water and subjected to taste evaluation, and the results are shown in figure 1 and table 1, and the results show that A2 has the best salty taste and better fresh taste, and the taste strength of the fresh taste and the salty taste is higher than that of the CR and CT groups, and prove that the addition of the compound leavening agent in the preparation process of the dry-cured mackerel has certain functions of reducing salt and increasing freshness, and improves the overall taste characteristics of the dry-cured mackerel. Therefore, further studies were conducted on the dry-pickled mackerel of group A2 (2% salt content, 2:1 ratio of honey yeast to Lactobacillus plantarum) and 2% salt + mixed group for short.
TABLE 2 taste evaluation results of dry-cured mackerel
Experimental example 2 sensory evaluation of dry-cured Spanish mackerel in example versus comparative example
(1) Sensory evaluation of dry-cured Spanish mackerel
The pieces of 3 kinds of dry-cured mackerel of example 1 (2% salt + mixed group) and comparative examples 1-2 were boiled over water for 15min, and then 13 sensory panelists were evaluated and scored by a scoring test, and sensory evaluation criteria were evaluated according to table 1.
TABLE 3 sensory Scoring criteria
A sensory evaluation group was composed of 13 participants, and experiments were performed to identify basic tastes such as sour, sweet, bitter, salty, and umami, and flavor evaluations (umami, salty, thick, sweet, and bitter) were performed on 3 kinds of steamed, dry-cured mackerel, respectively. The test was scored using a score of 10 and all results averaged. Each panelist scored independently, each time one sample was tasted, rinsed with distilled water, and tasted the next sample.
(2) Sensory evaluation result analysis of dry-cured Spanish mackerel
After 3 cooked dry-cured mackerel are randomly coded, sensory evaluation and taste characteristic evaluation are carried out according to the standard of Table 1, the quality result is shown in figure 2A, the taste and mouthfeel scores of a 2% salt + mixed group are superior to those of a control group (p <0.05), but no obvious difference exists in odor score (p >0.05), the mouthfeel score of a 2% salt control group is obviously lower than that of the other 2 groups (p <0.05), probably because the addition amount of salt is only 2%, the growth and reproduction of spoilage microorganisms cannot be effectively inhibited, the fish meat is loose and the mouthfeel is poor, the group inoculated with a fermentation microbial inoculum although the addition amount of salt is only 2%, the mouthfeel of the group added with the microorganisms and the control group added with 4% salt do not have obvious difference (p >0.05), and the growth and reproduction of the spoilage microorganisms can be effectively inhibited by lactobacillus plantarum and the honey zygosaccharomyces.
The results of the taste characteristics of the dry-cured mackerel are shown in fig. 2B, and the salty, umami and kokumi taste are the main taste of the dry-cured mackerel. The salty taste and the delicate taste of the 2% salt and mixed bacteria group are superior to those of the 2% salt control group, which shows that the addition of the mixed bacteria in the dry pickling process is more favorable for enhancing the taste characteristics of the dry pickled mackerel, and has better salty and fresh-increasing effects, thus the mixed inoculation of the lactobacillus plantarum and the honey-conjugated yeast is more favorable for generating flavor-developing substances in the dry pickled mackerel.
Experimental example 3 measurement of texture characteristics of dry-cured Spanish mackerel according to examples and comparative examples
(1) Measurement method
Referring to the method of plum sensitivity (change of endogenous protease during plum sensitivity and its influence on quality [ D ] of salted fish [ D ] university of agriculture in china, 2014.), 2 × 2 × 2 squares cut from 3 dry-salted mackerel samples of example 1 (2% salt + mixed bacteria group) and comparative examples 1-2 were slightly modified, using TPA mode, cylindrical probe, 20% compression set, trigger force 250N, speed 30mm/min before test, test speed 60mm/min, speed 30mm/min after test, parallel 10 times, and averaged.
(2) Analysis of dry-cured mackerel texture results
Texture characteristics of 3 groups of dry-cured mackerel samples were measured using a texture analyzer, hardness representing the force with which the teeth squeezed the sample, cohesiveness representing the contractile force inside the sample, stickiness representing the energy required for crushing before swallowing, and chewiness representing the energy required for chewing. The results are shown in table 4, the cohesiveness of the 3 groups of samples is not obviously different (p <0.05), the hardness, chewiness and adhesiveness of the 4% salt control group are significantly higher than those of the rest 2 groups (p <0.05), probably because the protein denaturation of the fish protein due to water loss during the dry-curing process of the 4% salt control group is caused by the fish protein, and the degradation of the fish protein by the microorganisms is weaker, which indicates that the 4% salt is added with a certain bacteriostasis effect. The 2% salt and mixed bacterium group continuously secretes protease in the dry pickling process to promote the degradation of protein, so that the hardness and the chewiness are reduced, the texture and the taste of the dry pickled mackerel are improved, and the quality and the taste are basically consistent with sensory evaluation.

Experimental example 4 electronic tongue measurement of dry-cured Spanish mackerel of examples and comparative examples
(1) Measurement method
The 3 dry-cured mackerel samples of example 1 (2% salt + mixed bacteria group) and comparative examples 1-2 were first cut into small pieces with scissors, placed in a household food processor and crushed, 10g of the crushed samples were weighed into a beaker (sealed with a preservative film), the beaker was placed in a pot after the water in the pot was boiled, and the beaker was steamed and boiled for 15min in a water-proof manner. Taking out from the pan, adding 140g of boiled water, fully stirring, performing ultrasonic treatment for 10min, finally centrifuging at 3000rpm/min for 5min, and taking the supernatant for electronic tongue testing.
(2) Electronic tongue sensory results analysis of dry-cured Spanish mackerel
The electronic tongue is used for simulating a taste recognition mechanism of a human tongue so as to obtain basic information of taste of a sample. The results are shown in fig. 3, the umami response value of the 2% salt + mixed bacteria group is significantly higher than that of the control group (p <0.05), the bitter response value is significantly lower than that of the two groups of control groups (p <0.05), and basically accords with the human sensory evaluation, which shows that the inoculation of the mixed bacteria in the dry pickling process can increase the production of the umami substances and reduce the production of the bitter substances, the salty taste has no significant difference from the 2% salt control group (p >0.05), the salty response value of the 4% salt control group is the highest, accords with the measured salt content, but has a slight difference from the human sensory evaluation, and the reason is that the salty taste of the electronic tongue is directly caused by inorganic salts such as salt, and in the human sensory evaluation, the umami substances and the thick substances cooperate with sodium chloride to improve the salty taste intensity.
Experimental example 5 determination of free amino acids of dry-cured Spanish mackerel according to examples and comparative examples
(1) Measurement method
Accurately weighing 5.00g of sample (example 1 (2% salt + mixed bacteria group) and 3 kinds of dry-cured mackerel of comparative example 1-2), adding 15mL of trichloroacetic acid with 5g/100mL, repeatedly homogenizing for 3 times, fixing the volume to 50mL, carrying out ultrasonic treatment for 30min, standing for 1h, taking 25mL of filtrate into a 50mL centrifuge tube, centrifuging for 15min at 10000r/min, filtering with a 0.22 mu m water system filter membrane, and analyzing the filtered filtrate by using a high performance liquid chromatograph by using an AgiLent automatic online derivatization method.
(2) Analysis of results on the content of free amino acids in dry-cured Spanish mackerel
Free amino acids are one of the main flavor substances in food products and can improve the taste characteristics of the food products. The results of the content of free amino acids in the dry-cured mackerel are shown in table 5, the content of total free amino acids in the 2% salt + mixed bacteria group is far higher than that in the two groups of control groups (p is less than 0.05), the ratio of fresh amino acids is higher than that in the two groups of control groups, and the ratio of bitter amino acids is lower than that in the two groups of control groups, so that the inoculation of microorganisms in the dry-curing process can promote the generation of free amino acids, is beneficial to the generation of fresh amino acids, and reduces the ratio of bitter amino acids, thereby improving the taste characteristics of the dry-cured mackerel on the whole, and mainly because the lactobacillus plantarum and the honey zygosaccharomyces secrete protease, peptidase and the like continuously in the growth and reproduction process to degrade the proteins in the fish meat.
The content of the umami amino acid in the 2% salt and mixed strain group is the highest, so that the addition of the mixed strain is more beneficial to the generation of the umami amino acid, the umami taste of the dry-cured mackerel can be better presented, and the umami amino acid can also generate a synergistic effect with sodium chloride, so that the umami taste and the salty taste are enhanced.
The research shows that the glutamic acid can show the capability of enhancing the salty taste in a low-concentration sodium chloride solution and has stronger salty taste enhancing capability than GMP and IMP; in fact, lysine, arginine, glutamic acid and aspartic acid can enhance the salty taste of food, and researches show that the addition of 0.7 percent of monosodium glutamate in the spicy soup can reduce the sodium addition by 32.5 percent; arginine and lysine, although bitter amino acids, also have the ability of enhancing the flavor, and can improve the salty taste intensity of the product to a certain extent.

Experimental example 6 changes in myofibrillar proteins of dry-cured Spanish mackerel of examples and comparative examples were analyzed by SDS-PAGE
(1) Measurement method
Referring to the method of Cao brochan, etc. (Cao brochan, Zhanglin, Hanyi, etc. change of myofibrillar protein structure in bacon processing [ J ] Chinese agricultural science, 2013,46(18): 3871) 3877) and slightly modifying, extracting myofibrillar protein from different stages (fresh meat, after fermentation, drying for 1d, drying for 3d and drying for 6d) of dry-curing mackerel by 2% salt + mixed bacteria group, the specific method is as follows:
mixing pulverized Spanish mackerel with 4 volumes (1: 4, w/v) of a mixture (solution A, 1:1, w/v) of a low-temperature frozen 0.1M KCl buffer (pH 7.0) and a 20mM Tris-HCl buffer, homogenizing at 10000r/min for 3 times and 30s each time by a high-speed homogenizer, filtering through a 20-mesh sieve (pore diameter 0.9mM), centrifuging at 5000r/min for 15min, pouring out the supernatant, and collecting the precipitate granules, namely crude myofibrillar protein. Repeating the steps for 3 times to obtain high-purity myofibrillar protein, and finally measuring the protein concentration by using a biuret method to adjust the concentration of the myofibrillar protein to 5 mg/mL.
The extracted myofibrillar proteins at each stage were analyzed by SDS-PAGE. The volume fraction of the selected separation gel is 12%, the volume fraction of the selected concentration gel is 5%, and the 1L electrode buffer contains 3.02g of Tris, 18.8g of glycine and 10% SDS 10 mL. Electrophoresis is carried out by adopting a 1mm gel plate; the loading amount of myofibrillar protein is 10 mu L; the voltage is 80V when the electrophoresis is started, and is changed to 120V after the sample enters the separation gel; after the electrophoresis was completed, the film was taken out and stained with Coomassie Brilliant blue for 1 hour (100mL of the staining solution contained 0.25g of Coomassie Brilliant blue R250, 45mL of methanol, and 10mL of glacial acetic acid), and then destained to be transparent with a methanol/glacial acetic acid destaining solution (the destaining solution contained 5% of methanol and 7.5% of glacial acetic acid).
(2) Analysis of Change results of Dry-pickled Spanish mackerel myofibrillar proteins
SDS-PAGE analysis showed the degree of proteolysis of Spanish mackerel during dry-pickling. As shown in FIG. 4, in Spanish mackerel after fermentation and dry-cured 1d, the staining intensity of protein bands at 95kDa, 37kDa and 30kDa begins to rise, which proves that the degradation of myofibrillar proteins begins, and the staining intensity of MHC (myosin light chain), Actin (Actin) and MLC-1 (myosin light chain) becomes obviously lighter along with the increase of dry-curing time, which indicates that the proteins are degraded continuously, and the main reason is probably that the degradation of the proteins is promoted by cathepsin in fish meat and protease and peptidase produced by lactobacillus plantarum.
The protease and endopeptidase secreted by lactobacillus plantarum and honey zygosaccharomyces are the main reasons of proteolysis, and the protein is continuously degraded into small peptide and amino acid with taste, while the main taste substance of the dry-cured mackerel is the small peptide, so the extraction, separation and identification of the taste peptide are carried out subsequently.
The method for separating and purifying the flavor-presenting peptide by ultrafiltration and GFC (gel column chromatography separation) comprises the following steps:
1) extraction of flavor-developing peptide extract
Extracting the flavor-developing peptide extract by a boiling water method, which comprises the following steps: 200g of sample meat (dried salted mackerel of example 1 (2% salt + mixed bacteria group)) was taken, 800mL of ultrapure water was added, homogenization was repeated 3 times, 3min each time, extraction was performed in a boiling water bath for 2h, centrifugation was performed (4 ℃, 10000r/min, 15min), and the supernatant was taken.
2) Ultrafiltration concentration of flavor-developing peptide extract
Filtering the flavor peptide extracting solution in the step 1) by a polypropylene filter membrane (50mm), and intercepting components of the flavor peptide extracting solution less than 3kD by using a 3kDa hollow fiber filter membrane column under the flow rate of 40r/min and the pressure of 5Psi by adopting an automatic tangential flow filtration system. The component extract and the flavor development peptide extract are subjected to vacuum freeze drying and concentration, and then are stored at the temperature of minus 40 ℃ for later use.
3) Gel column chromatographic separation of taste-giving peptides
Dissolving the lyophilized powder of the ultrafiltration component with a concentration of less than 3kDa in ultrapure water to 10mg/mL, filtering with 0.45 μm water phase membrane, and separating and purifying with Sephadex G-15 gel chromatographic column to obtain taste peptide.
And then, carrying out sensory evaluation analysis on the obtained flavor-presenting peptide, selecting a component with optimal sensory effect to carry out mass spectrum identification, finding 5 polypeptides (table 6) through liquid chromatography-mass spectrometry and software analysis, predicting by iUmami-SCM software that all peptide segments have delicate flavor, identifying and characterizing the flavor-presenting peptide by mainly combining the tendency scores of amino acid and dipeptide, and having higher accuracy on the basis of cross validation and independent test, thereby being an effective and promising flavor-presenting peptide identification method. The 5 polypeptides in the table are main flavor development substances of 2% salt and mixed bacteria group, and have certain contribution to the taste increase of the dry-cured mackerel.
