Manufacturing Quality Control of Peptone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessment of physical form, color, and homogeneity under controlled lighting conditions. |
| Odor | Sensory Evaluation | Qualified personnel evaluate characteristic odor to detect off-odors indicating degradation or contamination. |
| Solubility | Gravimetric Dissolution Test | Sample is dispersed in water at specified temperature and time; insoluble residue is filtered and weighed. |
| pH (1% w/v solution) | Potentiometric Titration | Hydrogen ion activity measured using calibrated pH electrode in aqueous solution at 25 C. |
| Total Nitrogen Content | Kjeldahl Method | Organic nitrogen is digested with sulfuric acid and catalyst, then distilled and titrated as ammonia. |
| Ash Content | Gravimetric Ignition | Sample is incinerated at 550-600 C to oxidize organic matter; residual inorganic oxide mass is determined. |
| Moisture Content | Loss on Drying (LOD) | Mass loss after drying at 105 C for 3 hours under standard atmospheric pressure. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Heavy metals react with thioacetamide under acidic conditions to form colored sulfide complexes, compared visually or spectrophotometrically. |
| Arsenic Content | Gutzeit Method | Arsenic is reduced to arsine gas, which reacts with mercuric bromide paper to produce a characteristic yellow stain. |
| Microbial Contamination (Total Aerobic Count) | Plate Count Agar (PCA) Method | Serial dilutions plated on PCA; colonies counted after aerobic incubation at 30-35 C for 48-72 h. |
| E. coli Presence | Most Probable Number (MPN) Method | Sample inoculated into lactose broth tubes; gas production indicates probable E. coli presence, confirmed by selective media. |
| Salmonella Presence | Enrichment and Selective Plating | Non-selective enrichment followed by selective enrichment and plating on XLD or BS agar with biochemical confirmation. |
