Food Business Network News With the continuous improvement of people's living standards, soda is gradually entering people's lives and becoming a healthy and fashionable drink. Soda can be divided into natural soda water and synthetic soda water. Synthetic soda water is a new type of beverage with a small amount of sweetener, trace elements and food flavor added to the aqueous solution of sodium bicarbonate. Press in carbon dioxide (ie carbon dioxide). The production of this kind of beverage aims to guide people to eat more alkaline foods or drink more alkaline water from a health perspective, thus helping to neutralize acidic substances in the body, which has huge market development space. However, soda drinks contain substances required for the growth of microorganisms, which can easily cause the total number of colonies to exceed the standard, and the pH value is weakly alkaline. The chemical preservatives allowed in GB2760-2014, except for parabens, remain in an alkaline environment. In addition, other chemical preservatives have no good antibacterial effect. Chemical preservatives have a certain degree of harm to the human body. As people pay more attention to food safety, this has caused widespread concern among consumers, and it has also brought great challenges to the food industry. Under this circumstance, biological preservatives have received widespread attention due to their natural, safe and low dosage. The replacement of traditional chemical preservatives with biological preservatives will be an inevitable trend in the development of food antisepsis and preservation technology. Ε-polylysine hydrochloride is a new type of natural biological preservative, which has good water solubility (very soluble in water), high safety (as lysine polymer), and broad spectrum of inhibition (for bacteria, Both mold and yeast have effects. It has a wide pH range (pH 3-8) and has been approved as a natural food preservative by Japan, Korea, and the United States. In 2014, China approved the use of ε-polylysine hydrochloride as a food additive in foods, and its maximum use in beverages was 200 ppm. The experimental study found that the addition amount of ε-polylysine hydrochloride in the soda beverage is 40-80ppm, which can significantly inhibit the growth of microorganisms, greatly extend the shelf life of the product, and has no effect on the taste of the soda beverage; As a natural preservative, ε-polylysine hydrochloride for soda drinks will also greatly enhance product competitiveness.
