Exploring the mystery of food additives: Application and safety analysis of sodium tripolyphosphate

Introduction

Sodium tripolyphosphate is a widely used food additive that plays an important role in food processing. This article will discuss the properties of sodium tripolyphosphate, its use, and its safety assessment in the food industry.
Properties and uses of sodium II, tripolyphosphate

1. Chemical properties

Sodium tripolyphosphate, chemical formula Na5P3O10, is an inorganic substance. It is based on phosphoric acid as raw material, neutralized with sodium carbonate, and then heated to 120℃ to produce sodium tripolyphosphate. It is soluble in water and its aqueous solution is alkaline.

2. Physical properties

Sodium tripolyphosphate is a white crystalline powder. At room temperature, sodium tripolyphosphate has a density of about 2.5g/cm³ and a melting point of 622 ° C.

3. Multiple functions in food processing

Emulsification: Sodium tripolyphosphate can make protein, fat, and other components dispersed in water, forming a stable emulsification system, thereby improving the taste and texture of food.
Moisture retention: It can combine with the moisture in the food to form a structure similar to jelly, thereby retaining the moisture of the food and increasing the taste and tenderness of the food.
Increase the taste: it can make the food more soft, tender, and smooth, thereby increasing the taste of the food.
Increase stability: it can make the food more stable, and prevent the food in the process of processing and storage precipitation, stratification, and other phenomena.
Increase color: It can make the food more colorful, thus increasing the appeal of the food.

The application of sodium tripolyphosphate in the food industry

1. Application in dairy products

Sodium tripolyphosphate is widely used in dairy products, such as yogurt, ice cream, cheese, and so on. It can increase the taste and stability of milk products, and prevent precipitation and stratification of milk products during processing and storage.

2. Application in meat products

In meat products, sodium tripolyphosphate can increase the tenderness and taste of meat products, and prevent drying and hardening of meat products during processing and storage.

3. Application in beverages

In beverages, sodium tripolyphosphate can increase the stability and taste of beverages, and prevent precipitation and stratification of beverages during processing and storage.

4. Application in other foods

In addition to the above foods, sodium tripolyphosphate can also be used in the processing of other foods, such as pastries, biscuits, puffy foods, etc. It can increase the taste and stability of these foods, and prevent deformation and cracking of these foods during processing and storage.

Safety assessment of food-grade sodium tripolyphosphate

1. The difference with industrial-grade sodium tripolyphosphate

Food-grade sodium tripolyphosphate is strict quality control and inspection, in line with national food safety standards. Industrial-grade sodium tripolyphosphate may contain some harmful substances, such as heavy metals, arsenic, etc., which may cause harm to human health.

2. Relevant scientific research and evaluation results of regulatory bodies

At present, a large number of scientific studies and regulatory agencies have evaluated the safety of sodium tripolyphosphate. These studies and evaluation results indicate that sodium tripolyphosphate is safe under normal use and does not pose a risk to human health.

Answers to frequently asked Questions

1. Is there a limit to sodium tripolyphosphate intake?

According to the recommendations of the World Health Organization and the Codex Alimentarius Commission, the allowable daily intake of sodium tripolyphosphate is 0-70mg/kg body weight. For the average adult, it is safe to consume less than 5g of sodium tripolyphosphate per day.

2. What are the potential risks of sodium tripolyphosphate?

Although sodium tripolyphosphate is safe under normal use, it can be hazardous to human health if consumed in excess. Excessive intake of sodium tripolyphosphate may cause symptoms such as kidney damage and gastrointestinal discomfort. In addition, sodium tripolyphosphate may also react with other substances to produce harmful substances.

Заключение

Sodium tripolyphosphate is a widely used food additive that plays an important role in food processing. This paper discusses the properties and uses of sodium tripolyphosphate and its safety assessment in the food industry. While sodium tripolyphosphate is safe under normal usage, consumers should still pay attention to ingredient lists and make healthy decisions when choosing foods.
