The testing process involved the following steps:
1. Protein content analysis: HPLC was used to determine the protein content of each sample.
2. Purity analysis: ELISA was used to detect the presence of contaminants such as bacteria, viruses, and heavy metals.
3. Microbiological safety testing: Samples were tested for the presence of Salmonella, E. coli, and other pathogens.
4. Physical and chemical analysis: Samples were tested for their texture, odor, and pH levels.
Results and findings
The results of the testing process are presented below:
1. Protein content: The average protein content of the 20 commercial products was 90.2% ± 2.5%.
2. Purity: All samples were found to be free from contaminants, including bacteria, viruses, and heavy metals.
3. Microbiological safety: None of the samples tested positive for Salmonella, E. coli, or other pathogens.
4. Physical and chemical analysis: The texture and odor of the samples were found to be acceptable, while the pH levels ranged from 6.5 to 7.5.
