Further, the soybean active peptide concentrated solution is prepared by adding water into soybean protein powder, wherein the mass volume ratio g/mL of the soybean protein powder and the water is 1:3-8, adding compound flavor protease accounting for 0.1-0.8% of the mass of the soybean protein powder, carrying out hydrolysis reaction for 50-120 min under the conditions of pH value of 8-9 and temperature of 40-60 ℃, centrifuging, taking supernatant, separating by an ultrafiltration membrane, controlling the ultrafiltration pressure to be 0.11-0.20 Mpa, and the reflux ratio to be 5-7:1, collecting membrane-passing solution, and concentrating to obtain the soybean active peptide concentrated solution;
the compound flavor protease is purchased from the biological technology limited liability company of Henghua channel in the east of Nanning
The product specification is as follows: 3 ten thousand mu/g
Optimum pH:5.0 to 9.0
Optimum temperature: 50-55 DEG C
The addition amount is as follows: 0.1 to 0.3 percent.
Further, a pickling method of leisure fish products comprises the following steps:
s1, preparing raw materials: cleaning raw material fish, removing viscera and scales, slicing, cleaning fresh plants of herba Houttuyniae and herba Rosmarini officinalis, and mashing to obtain raw material fish such as one of Carassius auratus, grass carp, cyprinus Carpio, black carp, and bream.
S2, preparing a pickling solution: mixing the concentrated solution of sodium hydroxide, rice wine, soy sauce, cordate houttuynia, rosemary, honey, eugenol and soybean active peptide according to the weight parts, and uniformly stirring to prepare pickling solution;
s3, primary curing: soaking the fish slices in a pickling solution for 10-30 min, taking out, preserving heat, placing in an incubator at 40-50 ℃, and preserving heat for 15-25 min to obtain a semi-finished product;
s4, secondary curing: soaking the semi-finished product in the pickling solution again for 40-60 min, taking out, preserving heat, placing in an incubator at 40-50 ℃, preserving heat for 1-3 min, sterilizing under high pressure, cooling, and packaging to obtain the leisure fish pickled product.
Further, in the step S3, the mass volume ratio g/mL of the fillet to the pickling liquid is 1000:30-55.
Further, the mass volume ratio g/mL of the fillet to the pickling liquid in the step S3 is 1000:60-75.
Compared with the prior art, the invention has the beneficial effects that:
the pickling liquid for the leisure fish is reasonable in raw materials and scientific in proportion, can inhibit oxidation of the fish slices during storage, reduce the decomposition rate of protein, prevent juice loss of the leisure fish, effectively protect cell tissues in the fish slices, and has higher water holding capacity; wherein, eugenol and soybean active peptide concentrated solution are added into the raw materials to be combined with the rest raw materials, and the stable substances are generated after complexing with oxidation-assisting metal ions by utilizing the action of the eugenol and soybean active peptide concentrated solution, so that partial free radicals are eliminated by virtue of reduction performance, thereby playing a certain role in resisting oxidation; the decomposition rate of protein is reduced, so that less alkaline substances are produced, and the fresh-keeping effect is achieved; meanwhile, the ionic strength in the fish meat is increased rapidly, calcium, magnesium, phosphorus and other ions in the muscle protein are chelated, the myosin in the meat is dissociated to be converted into a sol state, and the sol and the sarcoplasmic protein form a special net structure to maintain the water holding capacity of the leisure fish; in addition, the pickling technology is combined, the pickling process is divided into two pickling steps, the pickling time and the pickling temperature of each pickling step are controlled, and a good pickling effect can be achieved under proper conditions;
the leisure fish pickling liquid and the pickling process can replace the traditional high-concentration experimental pickling technology, and provide technical support and theoretical basis for the field of aquatic product pickling processing.

comparative example 2
The difference between this comparative example and example 3 is that the starting material of the pickling solution for a recreational fish product does not contain eugenol.
Comparative example 3
The difference between this comparative example and example 3 is that the raw material of the pickling solution for leisure fish products does not contain the soybean active peptide concentrate.
1. Quality change of leisure fish cured product
Thiobarbital acid number (TBA)
The leisure fish cured products of examples 1 to 4 and comparative examples 1 to 3 were stored at 4℃and the TBA value was measured for 2, 6 and 10 days, respectively, and the measurement results were shown in Table 1 below:
table 1:
as shown in the table above, the pickling solution of the invention can inhibit oxidation of fish fillets during storage, and compared with the comparative example group, the pickling solution has obvious synergistic effect of the raw materials, and the eugenol and the soybean active peptide concentrated solution are added to complex with oxidation-assisting metal ions to generate stable substances, and meanwhile, the pickling solution has certain reduction performance to remove partial free radicals, so that a certain antioxidation effect is achieved.
(II) volatile basic Nitrogen value (TVB-N)
The leisure fish cured products of examples 1 to 4 and comparative examples 1 to 3 were stored at 4℃and the TVB-N value was changed in 2, 6 and 10 days, respectively, and the measurement results were shown in Table 2 below:
table 2:
as shown in the above Table 2, the pickling solution for recreational fish can reduce the decomposition rate of protein, so that less alkaline substances are produced, the increase of TVB-N value of the recreational fish in the storage period at 4 ℃ is effectively delayed, a certain fresh-keeping effect is achieved, and the flavor of the pickled recreational fish product is ensured.
(III) variation of juice run-off Rate
The leisure fish cured products of the above examples 1 to 4 and comparative examples 1 to 3 were stored at-5℃and the change in the loss rate of the juice in the leisure fish was measured in 5, 15, 25 and 35 days, respectively,
juice loss rate= (W 2 -W 1 )/W 2 ×100%
W 2 For the mass before curing, W 1 For the quality of the cured product,
the measurement results are shown in Table 3 below:
from the results in Table 3, it is shown that the pickling solution of the invention can effectively prevent partial water of fish tissues from being frozen under the slightly freezing condition, so that the cell membrane structure is destroyed, the juice loss of recreational fish is prevented, and the cell tissues in fish slices are effectively protected; from the table, the longer the comparative example group time is, the higher the loss rate of juice is, so that the invention proves that the added eugenol and soybean active peptide concentrated solution can lead the ionic strength in fish to be increased more quickly, chelate calcium, magnesium, phosphorus and other ions in muscle protein, dissociate the myosin in the meat to be converted into sol state, and the sol and the sarcoplasmic protein form special network structure to maintain the water holding capacity of the leisure fish.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
