Description

A decocting method for improving yield and tenderness of beef steak with onion
juice
TECHNICAL FIELD
[01] The invention relates to a method for improving the quality and flavor of beef steak with onion juice, belonging to the technical field of animal product processing.
BACKGROUND
[02] Beef is very popular among consumers because it is rich in protein and amino acid that giving the meat both edible value and savory taste. As a deep-processed product of beef-steak, with its unique taste and flavor, and simple production process, it has won people's favor. Steak has become a very common food in China. However, due to the difference of beef varieties and meat quality, compared with western beef, Chinese beef has relatively hard texture, and the processing methods between Chinese and western steaks are still quite different. Therefore, it is necessary to study the formula and tenderization methods suitable for Chinese steaks.
[03] The quality of steak is the main cause for concern by consumers. In recent years, there have been many researches in this area. Wang Xiaochun, Sun Baozhong and others have studied the quality of pre-prepared steaks in the market. The results showed that there were obvious differences among the main quality indicators of steaks made from different parts of beef. (P < 0.05). There were no significant differences in pH, moisture and protein content of different brands and parts of steak (P> 0.05), while significant differences in hardness and fat content were occurred (P < 0.05), meaning the protein and fat content is low and the shear force is high. These unfavorable indicators what improvement should focus on in China for future.
[04] Niu Wenjuan and others studied the influence of different frying conditions on the center temperature of steak. The results showed that there were significant differences between frying temperature and frying time (P< 0.05); Lang Yumiao and others studied the effect of cooking temperature on the eating quality of fried steak. The results showed that the shear force, cooked meat rate, texture and sensory characteristics of fried steak were significantly affected by cooking temperature (P < 0.05), and the eating quality was significantly affected by the trend of muscle fibers (parallel or vertical muscle fibers) (P< 0.05). In order to improve the tenderness and prolong the preservation time of pre-prepared steak, ultra-high pressure combined with freezing was used to treat steak in the research of Wang Shuo and Xie Huiming. The results showed that the tenderness of pre-prepared steak was greatly improved; Angela and others found that the quality of steak was affected by the end temperature and thickness significantly, and cooking time, heating rate and cooking and dripping loss were affected by the thickness significantly (P<0.05); J.W.S and others compared the effects of different cooking methods on steaks and found that there were significant differences in quality with different cooking methods applied (P < 0.05); Previous experiments showed that the quality of steak was affected by many factors, among which the processing method was one of the most important. However, in recent years, there are few researches on basic formula and marinating technology of steak, especially on improving the quality and flavor of steak with onion juice.
SUMMARY
[05] The purpose of the invention is to provide a method for improving the quality and flavor of steak prepared with union juice. The method is to add freshly squeezed onion juice to steak, and optimize the amount of onion juice to be added and rolling time conditions. The marinated onion juice steak by this invention not only improves the quality and flavor, it also diversifies the marinating method for steak cooking. The purpose of the invention is realized by the following technical scheme.
[06] A method for improving the quality and flavor of beef steak with onion juice comprises the following steps: preparing onion juice; pre-preparing of raw meat; injecting onion juice; rolling and marinating.
[07] This invention optimizes the marinating formula for cooking the steak by experimenting the influences of different adding amounts of onion juice and different rolling time on the cooking loss, yield, color, shearing force and sensory quality of the steak, and by going through single factor experiment, the optimal amount of onion juice and rolling time were determined.
[08] Through single factor experiment, it was found that when the amount of onion juice was 9% (relative to the quality of steak) and the rolling time was 10 min, the cooking loss and shear force of marinated steak could keep a relatively low value, while the yield was relatively high, which effectively improved the quality, taste and sensory characteristics of steak. The method solves the problems of excessive oxidation and deterioration of meat color in the curing process of fresh steak, obtains steak products with low oxidation and good tenderness, and provides technical support for the development of basic formula of steak.

[039] Notice: a-dare in the same column of letters, when letters are different, it means a significant difference (P< 0.05).
[040] Figure 1 shows the changes in cooking loss of steak with different onion juice addition. It can be seen from Figure 1 that the cooking loss of steak with 9% onion juice is obviously lower than that of other groups, and the difference is significant (P< 0.05).
[041] Figure 2 shows the changes in steak yield when adding different onion juice. It can be seen from Figure 2 that the yield of steak with 9% onion juice is obviously higher than other groups, and the difference is significant (P < 0.05).
[042] Table 1 shows the differences in pH of steak with different amounts of onion juice was unsignificant (P> 0.05), but there was significant difference between the steak with onion juice and the control group without onion juice (P< 0.05), which was caused by adding onion juice.
[043] Table 2 shows the changes in red value of steak with different onion juice addition. It can be seen from Table 4 that the red value of steak with 9% onion juice is obviously lower than other groups, and the red value of steak with 9% onion juice is significantly different from other groups (P < 0.05). Because onion juice has antioxidant effect, there is a significant difference in the red value of steak with onion juice compared with the control group without onion juice (P < 0.05). The high antioxidant effect of steak with 9% onion juice was observed.
[044] Table 3 shows changes in shear force of steak with different onion juice addition. It can be seen from Table 5 that the shear force value of steak with 9% onion juice is obviously lower than that of other groups (P < 0.05). There was no significant difference between the other groups added onion juice (P>0.05). The shear force value of steak with 9% onion juice is low, which indicates that its tenderness is better.
[045] Table 4 shows changes in sensory characteristics of steak with different onion juice addition. It can be seen that the scores of flavor, taste and overall acceptability of steak with 6% and 9% onion juice are higher than those of other groups, and there is significant difference between them (P < 0.05). The all sensory characteristics of steak with 12% and 15% onion juice decreased, which was mainly due to the excessive amount of onion juice, which caused the steak itself to have strong onion spicy taste and poor acceptability.
[046] From the cooking loss, yield, color, shear force and sensory characteristics, it can be seen that the steak quality is the best when the onion juice is added at 9%, so this study takes 9% onion juice as the best addition.

[051] Notice: -are in the same column of letters, when letters are different, it means a significant difference (P<0.05).
[052] Figure. 3 shows the changes in cooking loss of steak at different rolling time. It can be seen from the figure that when the rolling time is 10 min, the loss of steak cooking is the lowest, and the difference is significant compared with other groups (P < 0.05). When the rolling time is longer than 10 min, the cooking loss tends to increase, which is related to long rolling time, loose muscle tissue, and decreased absorption and retention ability of pickling solution.
[053] Figure 4 shows changes in steak yield at different rolling time. It can be seen from the figure that when the rolling time is 10 min, the yield of steak is the highest, and the difference is significant compared with other groups (P< 0.05). When the rolling time is longer than 10 min, the yield of steak decreases, which is related to the long rolling time, which leads to the relaxation of muscle tissue structure, and reduces the absorption and retention ability of marinated solution.
[054] Table 5 shows the changes in redness value of steak under different rolling time. It can be seen from the table that when the rolling time is 10 min, the redness value of steak is the lowest, which is significantly different from other groups (P < 0.05). When the rolling time is longer than 10 min, the redness value of steak increases, which may be related to the long rolling time, and the steak is oxidized during rolling.
[055] Table 6 shows the changes in shear force value of steak at different rolling time. It can be seen from the table that when the rolling time is 10 min, the shear force value of steak is the lowest, which is significantly different from other groups (P < 0.05).
[056] Table 7 shows the changes in sensory characteristics of steak at different rolling time. It can be seen from the table that when the rolling time is 10 min, the color, flavor, taste and overall acceptability are superior to those of other groups, and the difference between them is significant (P < 0.05).
[057] According to the above experimental conclusions, this study selected 9% onion juice and 10 min rolling time as the best technological conditions for the basic formula of steak. Under these conditions, the taste, flavor and other quality indexes of steak with onion juice were the best.
[058] Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms, in keeping with the broad principles and the spirit of the invention described herein.
[059] The present invention and the described embodiments specifically include the best method known to the applicant of performing the invention. The present invention and the described preferred embodiments specifically include at least one feature that is industrially applicable
