Test example
Based on the quality of the object (the sea sedge sandwiched by the sea weed) sprayed with the mixed fishy smell removing solution and by taking the sensory evaluation score as an index, the fishy smell removing effect of different mixed fishy smell removing solutions on the product is measured by designing four-factor four-level orthogonal tests with the garlic juice addition amount (1.5, 2.0, 2.5, 3.0 percent), the ginger juice addition amount (1.5, 2.0, 2.5, 3.0 percent), the cooking wine addition amount (0.8, 1.6, 2.4, 3.2 percent), the white vinegar addition amount (0.8, 1.6, 2.4, 3.2 percent) as factor levels. In sensory evaluation of samples, 10g of the sandwich seaweed byproduct powder was weighed into a cup, 100ml of boiling water was added and stirred uniformly, 10 trained professionals were invited to form a sensory evaluation group, and the samples were evaluated using the sensory evaluation criteria for sandwich seaweed byproduct powder shown in table 1.

Figure BDA0003818013780000081
As shown in table 2, after analyzing and verifying the results of the cross-country test, the optimal formula of the deodorizing liquid for the sandwich sea sedge byproduct is obtained by adding 2% of garlic juice, 2% of ginger juice, 1.6% of cooking wine and 1.6% of white vinegar, namely, the deodorizing liquid prepared by uniformly mixing the garlic juice, the ginger juice, the cooking wine and the white vinegar according to the mass ratio of 1. According to the range analysis, the primary and secondary sequence influencing the fishy smell removing effect is the ginger juice adding amount, the cooking wine adding amount, the white vinegar adding amount and the garlic juice adding amount.
And evaluating the influence of the addition amount of the lotus root starch on the quality and the stability of the product. During research, the quality and the stability of the product are respectively measured by sensory score and centrifugal precipitation rate. The centrifugal precipitation rate is determined by mixing the mixed powder with boiling water at a ratio of 1. The centrifugal precipitation rate is inversely related to the product stability. The results are shown in FIG. 1, with different letters on the results indicating significant differences (p < 0.05). As can be seen from figure 1, the influence of the addition amount of the lotus root starch on the quality and the stability of the product is remarkable, the sensory score of the product is increased and then reduced along with the increase of the addition amount of the lotus root starch, and the sensory score reaches the highest score when the addition amount is 20 g. When the addition was >20g, the product was excessively viscous and the sensory score decreased. The influence of the addition amount of the lotus root starch on the stability of the product is large, when the addition amount is 10g, the centrifugal precipitation rate is the largest, the stability of the product is the worst, and as the addition amount of the lotus root starch is increased, the centrifugal precipitation rate is reduced, and the stability of the product gradually becomes better. Comprehensively considering, in order to ensure the quality and stability of the product, the addition amount of 20g of lotus root starch is most suitable.
Evaluating the influence of different mass ratios of sandwich thallus Porphyrae byproduct powder, amylum Nelumbinis Rhizomatis, rice flour, herba Avenae Fatuae powder and parched rice flour on product quality and stability (figure 2-figure 3). When the sample is evaluated in a sensory mode, 16g of sandwich seaweed byproduct powder is weighed in a cup, and 160ml of boiling water is added for stirring. A sensory panel was formed by inviting 10 trained professionals to use the sandwich seaweed by-product reconstituted powder sensory evaluation criteria as shown in table 3. As shown in Table 4, the mass of the sandwich seaweed by-product powder in Table 4 was constant at 52.5g.

And (3) performing multiple regression fitting on the table 4 data by using Design-Expert8.0 software, wherein a regression model P is less than 0.01, which shows that the quadratic regression equation model has very obvious difference and can be used for evaluating the influence of different mass ratios of raw and auxiliary materials on the quality and stability of products. The result shows that the brewing powder prepared by uniformly mixing the sandwich seaweed by-product, the lotus root starch, the rice flour, the oat flour and the fried rice flour according to the mass ratio of 52.5 to 10 is optimal, the brewing powder has fine and smooth mouthfeel, moderate viscosity and fragrance, no pimple, no layering, uniform color and good fluidity, and has rich seaweed and cereal fragrance and no other foreign flavor or fishy smell.
Evaluating the difference of the influence of different deodorization modes on the volatile smell of the brewing powder. The electronic nose device used in the test had 10 sensors, which were R1: W1C (aromatic component, benzenes), R2: W5S (oxynitrides), R3: W3C (aromatic component, ammonia), R4: W6S (hydride), R5: W5C (short-chain alkane aromatic component), R6: W1S (methyl), R7: W1W (sulfide), R8: W2S (aldol), R9: W2W (aromatic component, organic sulfide), and R10: W3S (long-chain alkane). Analysis of odor components of three samples by electronic nose as shown in fig. 4, the response values of the 2 sensors of R4 and R10 of sample B and sample C almost agreed with the response value of sample a. However, the R2 response value of sample C is greatly improved compared with that of sample A and sample B, because certain odor substances of the deodorization liquid and the parched rice flour enter the sandwich seaweed by-product to react, so that a large amount of nitrogen oxide compounds are generated in the materials. In addition, the response values of R6 and R8 of samples B and C were significantly lower than that of sample A, because the use of the deodorizer and parched rice flour resulted in a decrease in the amount of methyl and aldol-like substances in the material. The result shows that the use of the fishy smell removing liquid and the fried rice flour is one of the important reasons for better fishy smell removing effect of the material.
The stability, the centrifugal precipitation rate and the caking rate of three different brewing powders were compared. The brewing stability is measured by putting 10g of brewing powder into a 100mL measuring cylinder, adding 100mL boiling water, stirring uniformly, standing for 3min, and measuring the height h of the supernatant 1 And the total height h of the suspension 2 In h, with 1 Account for h 2 The percent of (c) is a measure of the reconstitution stability of the sample, with greater ratios being less reconstitution stability. The caking rate is about 10g of the mixing powder (m) 1 ) Adding 100mL of boiling water into a beaker, standing for 10min, adding water to dilute to 2 times of volume, sieving with a 20-mesh sieve, and drying the oversize product to constant weight (m) 2 ) The caking rate is defined as m 2 Occupy m 1 The greater the ratio, the poorer the reconstitution stability. As can be seen from FIG. 5, under the same brewing conditions, the commercially available soybean brewing powder is easy to agglomerate, the commercially available black soybean brewing powder is easy to precipitate, and the product of the present invention has the best brewing performance. In FIG. 6, the results are highlighted with different letters indicating that the results are significantly different (p < 0.05).
