What is the recommended maximum allowable concentration of ε-Polylysine hydrochloride?

ε-Polylysine hydrochloride is a food preservative that has been used in the food industry for several years. It is a natural polymer made up of lysine and has been used to prevent the growth of bacteria and fungi in food products. The use of ε-Polylysine hydrochloride in food products has been approved by many countries, including the United States, Japan, and Europe. However, there are recommended maximum allowable concentrations of ε-Polylysine hydrochloride in food products.

The recommended maximum allowable concentration of ε-Polylysine hydrochloride in food products varies depending on the country. In Japan, the maximum allowable concentration of ε-Polylysine hydrochloride in food products is 1,000 ppm. In the United States, the Food and Drug Administration (FDA) has not established a specific limit for the use of ε-Polylysine hydrochloride in food products. However, it has been recognized as a Generally Recognized As Safe (GRAS) substance, which means that it is considered safe for use in food products at levels that are consistent with good manufacturing practices.

The European Food Safety Authority (EFSA) has established an acceptable daily intake (ADI) for ε-Polylysine hydrochloride. The ADI is the amount of a substance that can be consumed daily over a lifetime without causing harm to human health. The EFSA has set the ADI for ε-Polylysine hydrochloride at 7.5 mg/kg body weight per day.

It is important to note that the recommended maximum allowable concentration of ε-Polylysine hydrochloride in food products is not a safety limit. The limit is based on the efficacy of the preservative and the potential impact on the taste and texture of the food product. Exceeding the recommended maximum allowable concentration of ε-Polylysine hydrochloride may result in negative sensory effects, such as bitterness or astringency, which can affect the overall quality of the food product.

In addition to the recommended maximum allowable concentration of ε-Polylysine hydrochloride in food products, it is also important to consider the overall safety of the preservative. The safety of ε-Polylysine hydrochloride has been extensively studied, and it has been shown to be safe for use in food products. However, like any food additive, ε-Polylysine hydrochloride may cause adverse reactions in some individuals, especially those with allergies to lysine or histamine intolerance.

In conclusion, the recommended maximum allowable concentration of ε-Polylysine hydrochloride in food products varies depending on the country. It is important to adhere to these limits to ensure that the preservative is effective and does not negatively impact the sensory qualities of the food product. It is also important to consider the overall safety of the preservative, including any potential adverse reactions in certain individuals. By following these guidelines, the use of ε-Polylysine hydrochloride can help to extend the shelf life of food products and ensure their safety for consumption.
