The stability of ε-polylysine hydrochloride powder is significantly affected by temperature. It exhibits good stability under high-temperature conditions. It is reported that its antibacterial capability remains unaffected when maintained at 80°C for 60 minutes or at 120°C for 20 minutes. This thermal stability allows ε-polylysine hydrochloride to withstand heat treatments commonly used in food processing, such as pasteurization and high-temperature cooking, ensuring that it does not become inactive due to high temperatures during food processing.
Due to its high-temperature stability, ε-polylysine hydrochloride can undergo sterilization along with food ingredients, which helps prevent secondary contamination during food processing and improves food safety.
Within a certain temperature range, the antibacterial activity of ε-polylysine hydrochloride is minimally affected by temperature. This means that its antibacterial effect can remain stable even if there are temperature fluctuations during food processing and storage.
Although ε-polylysine hydrochloride demonstrates good stability at high temperatures, it is important to avoid extreme high-temperature conditions in practical applications to prevent irreversible damage to its structure.
Additionally, the interaction between temperature and other factors (such as pH value and food components) may also affect the stability of ε-polylysine hydrochloride. Therefore, in food preservation applications, various factors should be considered comprehensively to develop the best preservation plan.
Temperature has a significant impact on the stability of ε-polylysine hydrochloride powder. Its high-temperature stability provides strong assurance for food processing and preservation. However, in practical applications, it is crucial to control the temperature range to ensure its stability and antibacterial effectiveness.
