Description

Making method for improving flavor of low-sodium salt roasted chicken
Technical Field
The invention belongs to the technical field of food processing, and relates to a preparation method for improving the flavor of low-sodium salt roasted chicken.
Background
The salt roasted chicken is a traditional delicacy with the characteristics of Guangdong Hakka, and is deeply favored by consumers due to tender and smooth meat, crisp and crisp skin and unique salty and fragrant mouthfeel. The salt baking method is a traditional method for baking chicken in salt, takes whole chicken as raw materials, evenly coats salt and sand ginger on the surface of chicken, wraps the chicken with oil absorption paper, and is prepared by the processes of frying hot crude salt and baking. The salt plays two main roles: the chicken quality is improved, the muscle protein dissolution is promoted, the hydration capacity is enhanced, the juice loss is reduced, and the water retention is improved; and the flavor enhancer can effectively improve the flavor characteristics of the chicken. However, if the high-salt diet is taken for a long time, hidden troubles exist in human health, and diseases such as hypertension, cardiovascular diseases, osteoporosis and the like can be caused. With the increasing importance of modern people on health, low-salt and low-sodium diet is gradually advocated. Therefore, how to reduce the salt without influencing the mouth feeling, texture and flavor of the salt roasted chicken is a research problem which needs to be solved urgently.
In addition, the salt roasted chicken adopts the traditional pickling method, so that the salt has slow permeation rate and uneven permeation quantity, the taste and quality standard of the product are unstable, and the large-scale industrialized production requirement cannot be met. Therefore, in order to solve the problems of standardization and industrialization of salt roasted chicken, the traditional pickling technology needs to be innovated by combining a new technology with a new process, realize mechanical and automatic production and improve the production scale and efficiency.
Potassium chloride (KCl) is the most common sodium salt substitute salt, with a molecular composition similar to NaCl, with salty taste characteristics. KCl solution can produce flavor similar to NaCl. However, when KCl is used instead of NaCl, K is the cause+Is weaker than Na+And the protein is not easy to be combined with the surface of the protein, so that a thin hydration layer is formed on the surface of the protein, and the water holding capacity of the product is reduced. Also, when the KCl substitution exceeds 50%, an unacceptable bitter taste is produced in the meat product, affecting the overall flavor. Therefore, the effect of using the potassium salt alone instead of the sodium salt is not good. Disodium guanylate, as a flavor enhancer, effectively masks the bitter taste of KCl and enhances other flavors, thereby improving the overall flavor that is diminished by the reduction of salt conductivity. Carrageenan is a negative polysaccharide with gelling property, can improve the water retention property, texture, internal water distribution state and the like of meat products, and has wide application in meat product processing.
As a novel pickling method, the vacuum rolling pickling technology is combined with a rolling mode under a vacuum condition, so that the permeation speed of a pickling agent is increased, the tenderness of meat products is improved, and the application of the vacuum rolling pickling technology in pickled food is more and more extensive. Research on the change of the quality of the preserved meat in the processes of vacuum pickling and traditional pickling, and the like shows that compared with the traditional pickling method, the vacuum pickling can play a role in improving the water retention of the preserved meat, promoting the absorption of a pickling agent and improving the flavor and the color of the preserved meat.
The prior art only relates to the optimization of a salt roasted chicken processing technology, and no research is carried out on low-sodium salt roasted chicken. A preparation method of salt roasted chicken (patent application publication No. CN105495391A) adopts a traditional wet pickling process, has low pickling efficiency, and cannot ensure the stability of product quality. A production method of salt roasted chicken with unique flavor (patent application publication No. CN 106722326A) adopts rolling, kneading, pickling, air drying and steaming processes, shortens production time, improves production efficiency, and the prepared product has good fiber property of meat, and has fresh and tender texture by matching with composite phosphate. However, the hot air drying is adopted, which easily causes excessive water loss of chicken and meat stiffness. The cooking process is convenient for standard operation, but deviates from the characteristic of salt baking and affects the quality.
According to the method, potassium chloride is firstly compounded with guanylate disodium to replace part of sodium chloride, so that the use amount of salt is reduced, and the special salt baking fragrance is kept; the pickling efficiency and the tenderized meat quality are improved by combining the intermittent vacuum rolling and kneading with the standing pickling mode, and the effect of deep taste is achieved. And a gradient cold air drying mode is adopted, so that the moisture content of chicken is reduced, the taste of crispy meat balls is facilitated, the fat oxidation is accelerated, and the formation of flavor substances is further promoted.

As shown in Table 2, different preparation processes have significant influence on the hardness and chewiness of the salt roasted chicken. The hardness of the salt roasted chicken prepared in the examples 1, 2 and 3 is 2219.937g, 2647.367g and 2406.599g respectively, while the hardness of the comparative example prepared by the traditional process reaches 3982.545g, which is far higher than that of the product prepared in the examples (P is less than 0.05), and the taste is too hard. In terms of chewiness, the chewiness of the salt roasted chicken of the example is reduced by 11.3 to 25.6 percent compared with that of a comparative example prepared by the traditional process. Proved that the meat quality and taste of the chicken can be obviously improved by the intermittent vacuum rolling pickling and gradient low-temperature air drying process. Meanwhile, the final salt content of the product prepared in the embodiment of the invention is about 2.1 percent, which is obviously lower than the high salt content of the comparative example, and the preparation of the low-sodium salt roasted chicken is realized.
3. Identification of volatile aroma components of salt roasted chicken prepared in example 1 and commercially available salt roasted chicken
The volatile aroma components of the salt roasted chicken prepared in the example 1 and the commercially available salt roasted chicken were qualitatively analyzed by GC-MS. As can be seen from FIG. 2, the total number of volatile compounds and the composition of different types of volatile compounds detected by the salt roasted chicken prepared in example 1 and the commercially available salt roasted chicken are different. The salt roasted chicken prepared in the example 1 has a total of 52 compounds, wherein 10 hydrocarbon compounds, 15 alcohol compounds, 13 ketone compounds, 5 acid compounds and 9 ester compounds are detected. And 56 compounds are detected in the comparative example, wherein 20 hydrocarbon compounds, 12 alcohol compounds, 10 ketone compounds, 8 acid compounds and 6 ester compounds are detected. The comparative example has a higher amount of hydrocarbon species, which are mainly olefinic species, than example 1. The reason is that the salt roasted chicken powder is added in the pickling process of the comparative example, and most of volatile aroma components of the salt roasted chicken powder are olefin substances.
The aldehyde substance is one of the most important characteristic volatile flavor substances of chicken, and is a characteristic flavor substance generated by heating fat. In example 1 and the commercially available salt-baked chicken, aldehyde substances such as hexanal, octanal, (E) -2-octenal, nonanal, decanal, benzaldehyde, anisic aldehyde, and cinnamaldehyde were detected. However, the aldehyde substance of example 1 is present in a relatively large amount and its relative content amounts to 11.85%, while the comparative example is only 7.94%. The types and the amounts of the carbonyl compounds such as aldehydes, ketones and the like detected in example 1 are higher than those of the comparative examples.
Therefore, the salt roasted chicken prepared by the invention uses potassium chloride compounded with disodium guanylate as a partial substitute of sodium chloride, and adopts an intermittent vacuum rolling and standing pickling process, so that the salt consumption is reduced, and the flavor of the salt is not influenced. Through the gradient cold air drying treatment, the water activity of chicken is reduced, the content of free amino acid is improved, the fat oxidation in the salt baking process is accelerated, the generation of meat-flavor substances is promoted, and the flavor of the product is rich.
