Explore the methods to improve the inspection quality of food additives such as lactic acid

Abstract: The smooth progress of food quality inspection is directly related to human health, is the basis for ensuring that people effectively obtain basic rights and interests, and maintains the harmonious and stable development of society
.
Therefore, quality inspectors in the food industry should think from multiple perspectives when performing inspection tasks, fully integrate their valuable work experience and brand-new food inspection concepts, and be able to analyze the inspection data of food additives such as lactic acid, so that the food industry is safe It operates smoothly in a stable environment, and the quality of food safety inspection work has been further optimized
.
Based on this, this article discusses improving the inspection quality of food additives such as lactic acid for reference
.

Keywords: lactic acid; food additives; quality inspection; food safety .
The inspection of
food additives is extremely complicated.
Relevant technicians will not only be exposed to the inspection samples of multiple additives, but also need to consider the type and nature of each additive.
Suitable inspection technology
.
When performing inspection work, make relevant preparations, which can be carried out smoothly in accordance with established procedures, with higher inspection quality, and improve people's quality of life, so that they can buy and eat all kinds of food with confidence
.
Relevant staff should promptly innovate the original work concept to further improve the accuracy of the inspection work
.
This article analyzes and summarizes the working methods of the food quality inspection department at this stage, and puts forward a feasible food additive inspection plan
.

1 Improve the basic quality of the staff
As the results of food inspection are directly related to people's diet safety, the staff of the inspection unit must have a higher comprehensive quality in order to obtain the most accurate test data in the shortest time [1]
.
Therefore, the inspector needs to have a good mental state and a strong sense of responsibility
.
Inspection work needs to strictly carry out each operation step.
Regardless of controlling the addition of test drugs or maintaining the temperature of the inspection environment, relevant staff need more thinking and patience, so as to ensure the smooth development of follow-up work to the greatest extent
.
In order to significantly improve the comprehensive literacy of on-the-job inspectors, relevant units need to regularly organize employees to participate in new inspection technology lectures, so that they can obtain new ideas in inspection work, and effectively improve the overall efficiency of each inspection step, so that food Inspection work can be of higher quality
.

2 Choose suitable equipment and inspection reagents.

Food inspection work has higher quality, and relevant technical personnel are required to do the following
.
① Select the right basic inspection equipment and related reagents to ensure that all inspection work can have a high quality in the initial stage, so that the performance of the inspection equipment can be fully reflected
.
②Technical personnel need to fully maintain various inspection instruments and related drugs in their daily work to ensure that the result data information of all inspection work is true and reliable, and the service life of the equipment can also be effective on the original basis.

.
③Technical personnel need to have sufficient professionalism, and any reagents used must comply with the established rules to fundamentally avoid the deterioration of reagents from causing serious impact on the test results
.
For example, when the staff inspects lactic acid food additives, they need to prepare non-polluting culture media and basic lactic acid testing basic drugs such as hydrochloric acid solution, which can provide sufficient basic support for subsequent inspections
.
Technicians need to test the tightness and accuracy of testing equipment such as incubators, thermometers, and pipettes, and perform the testing steps in an orderly manner
.
During the test operation, it is necessary to operate the inspection equipment one by one in accordance with the established steps
.
To this end, relevant technical personnel should effectively improve their basic literacy
.

3 The
inspection work with suitable food additive inspection technology is highly comprehensive
.
With the continuous progress of the food industry, in order to improve the taste and quality of food, a large number of additives are added to the food when it is made.
The quality inspection of additives requires the application of different inspection techniques.
The main principles of these inspection techniques are quite different.

.
Therefore, technicians should do a good job in the research of various technical core concepts during inspection work, so that they can be handy in various inspection work, so that the quality of inspection work can be steadily improved, and the inspection efficiency will be higher
.
When testing the same food additive, it is necessary to use corresponding testing methods according to different testing purposes [3]
.
For example, the lactic acid content ratio test requires the use of liquid chromatography to obtain the peak area of ​​lactic acid to understand the ratio of lactic acid in food
.
When testing the lactic acid content, it is necessary to prepare reagents such as phenolphthalein reagent and sulfuric acid standard solution, and calculate according to formula (1)
.


Where: lactic acid content; ₂ titration blank consumption of sulfuric acid standard solution volume, mL; 1 -titration sample consumption of sulfuric acid standard solution volume, mL; C- concentration of sulfuric acid standard solution, mol/L;-sample mass, g; 0.
090 08—The milligram equivalent of lactic acid
.

Calculating the formula according to the inspection data can timely understand the specific content of lactic acid inspection in the sample, so that the technicians can understand the data information and food quality of lactic acid, which has an extremely important role in promoting the smooth development of the food industry in China, so that the follow-up work can be Smooth progress in a safer and more stable state promotes higher quality of work
.

4 Strictly control the experimental data error.

Food inspection results will be affected by external influences, resulting in that the inspection results are not sufficiently scientific and reasonable.
Inspectors need to think from multiple perspectives and follow the steps to avoid human errors and ensure the integrity of the inspection data.
Authenticity gives the food industry more direction for development [4]
.
For example, lactic acid inspection should be strictly done in each operation step
.
①The technicians need to do a good job in the cultivation of the detection bacteria.
The colony culture is cultured at 30 ℃ for 24 h, and stored in the refrigerator at 2 to 5 ℃.
This step needs to strictly control the temperature of each culture stage
.
②Ensure that the physiological saline is in a sterile state, wash down the cultured flora and make it into a bacterial suspension
.
③Plate preparation needs to control the number of culture plates and preparation temperature, especially the entire culture process needs to be carried out in a sterile environment, so as to minimize human error, reduce the error of experimental data, and improve the accuracy of test data [5]
.
In addition, if there is an operation error in the inspection, it needs to be re-inspected to fundamentally guarantee the authenticity of the inspection results
.

5 Conclusion
In summary, food inspection-related technical personnel need to study more food inspection techniques, and can use more advanced inspection techniques in various inspection tasks to improve food inspection efficiency
