With the rapid development of Chinese economy, the rise of new business models, the accelerated pace of people's life, the change of traditional life style and the diversified development of consumption demands, the staple food gradually changes from home-made to socialized supply, and the convenient staple food becomes an important supporting industry of the convenient food industry. The instant rice product matched with Chinese dishes with rich flavor and balanced nutrition is favored by modern young consumers, and the market development space is huge. However, starch in the rice is easy to age in the process of freezing and refrigerating the instant rice product, so that the problems of poor product taste, short shelf life, low digestibility and the like are caused, and the taste and flavor of the fresh rice cannot be recovered after reheating. The phenomenon of fat oxidation and taste change also exists in the storage process of dishes, and the eating quality of the products is seriously influenced.

Sensory evaluation method: 10 professionally trained sensory evaluators (5 men and 5 women) were selected for sensory evaluation in the treatment group and the control group. The evaluation time is arranged at 2h after meals, and the evaluation requires silence and cannot be discussed. Sensory scoring was performed according to table 1. And calculating an average value according to the scoring result of each sensory evaluator, discarding the persons with large scoring result errors, and recalculating the average value after discarding the persons. The results of the experiment are shown in FIG. 2.

Method for measuring degree of gelatinization
Pretreatment in a test: weighing 20 g of rice sample, pouring the sample into 200mL of absolute ethyl alcohol for soaking until the rice sample is completely crushed and dehydrated, then carrying out suction filtration, completely soaking the precipitate after the suction filtration by using 100mL of petroleum ether, stirring, carrying out suction filtration, finally drying the precipitate in a 30 ℃ forced air drying oven until the precipitate is completely dried, and crushing the precipitate by using a crusher and sieving the dried precipitate by using a 100-mesh sieve for later use. Take-Amylase method: 1.00g of each of the treated samples was weighed and placed in two 150mL Erlenmeyer flasks labeled Y1 and Y2, and another Erlenmeyer flask without sample labeled Y3 was used as a blank. 50mL of distilled water is respectively added into three 150mL conical flasks, the conical flask Y1 is placed in a boiling water bath for gelatinization for 20min (stirring is not stopped during heating so that the gelatinization is complete), then the mixture is rapidly cooled to room temperature, 5mL of 5% -Taka-amylase is respectively added into the three conical flasks, the mixture is subjected to water bath for 2 hours (stirring is usually carried out) in a constant-temperature water bath kettle at the temperature of 45 ℃, 2mL of 1mol/L hydrochloric acid solution is respectively added into the three conical flasks after the mixture is taken out, and the volume is 100 mL. After filtration, 10mL of filtrate was taken out of each erlenmeyer flask and placed into three 100mL small erlenmeyer flasks, 10mL of 0.1mol/L iodine solution and 18mL of 0.1mol/L sodium hydroxide solution were added, after a stopper was added and the erlenmeyer flasks were left to stand in a dark room for 15min, 2mL of 10% sulfuric acid solution was added, titration was performed with 1mol/L sodium thiosulfate standard solution, 1% starch solution was added as an indicator when the sample became light yellow, the titration was performed until colorless, and the volume of sodium thiosulfate consumed was recorded. The results of the experiment are shown in FIG. 3.
The method for measuring the thiobarbituric acid value comprises the following steps: weighing 10.00g of treated rice ball sample, uniformly stirring, adding 25mL of distilled water, homogenizing, adding 25mL of 5% TCA solution, uniformly stirring, filtering, taking 5mL of supernatant, adding 5mL of TBA solution, heating in a water bath kettle at 80 ℃ for 40min, cooling to room temperature, measuring absorbance at a wavelength of 532nm, and calculating the content of malondialdehyde by using 1,1,3, 3-tetraethoxypropane as a standard curve to represent the TBA value, wherein the unit is mg/kg. The results of the experiment are shown in FIG. 4.
And (4) analyzing results:
as can be seen from FIG. 2, the rice ball samples treated with rice anti-aging and dish anti-oxidation treatments and the control group samples had uniform color and luster, good texture, sufficient flavor, and no unpleasant odor at 0 day. During storage, the sensory scores of the two groups of samples gradually decline, but the sensory scores of the treatment groups are always higher than those of the control group. On day 15, the color of the control group sample is gray, the elasticity of the tissue morphology is seriously reduced, the texture is hard, and the reduction range of the sensory score of the blank control group is increased after 15 days. Compared with the blank group, the processed group sample has uniform stuffing color, the stuffing has stronger fragrance, and the taste of the rice is kept better.
As can be seen from fig. 3, the gelatinization degree of the cooked rice tended to decrease with the increase of the storage time in the treated group and the control group under the refrigeration condition at 4 ℃. The samples in the control group all rapidly declined in gelatinization degree in the first 3 days of storage. When the storage time is in the range of 3-15 days, the decrease of the gelatinization degree of the sample is slowed down compared with the previous 3 days. After 15 days of storage, the gelatinization of the samples began to stabilize and the decline tended to flatten out, indicating that the starch retrogradation of the rice in the samples was substantially complete by 15 days of storage. Compared with the control group, the reduction of the rice gelatinization degree of the treated sample is inhibited, which shows that the anti-aging agent can effectively delay the reduction of the rice gelatinization degree and improve the rice taste.
As shown in figure 4, the TBARS values of the two groups of samples show a rising trend along with the increase of the storage time, but the TBARS values of the samples of the treated group are always lower than those of the control group, which shows that the anti-oxidation treatment can effectively inhibit the fat oxidation of dishes and inhibit the flavor rancidity.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
