Sodium diacetate is a highly effective antifungal preservative with a wide range of applications.

Sodium diacetate, the molecular formula is C4H7NaO4, the trade name is Vita-crop, also known as sodium diacetate, sodium diacetate, its properties are white crystals with an acetic acid smell, it is hygroscopic and highly soluble in water , flammable and stable in cool, dry conditions.

According to the “China Sodium Diacetate Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028” released by the Industrial Research Center, Sodium diacetate mainly penetrates into the cell walls of fungi, molds, bacteria and other cells through decomposed molecular acetic acid to interfere with the interaction between enzymes, thereby achieving antibacterial effects. While being anti-fungal and antiseptic, sodium diacetate will not be affected by the pH of the food itself, nor will it change the original characteristics of the food. It can retain the aroma and nutrients of the food to the maximum extent, and is used as a sour agent and improver.

Compared with other preservatives, sodium diacetate has better antiseptic properties than benzoate preservatives. Its inhibitory effect on Aspergillus niger, Aspergillus flavus, Rhizopus niger, and Trichoderma viride is better than potassium sorbate, and its smell is milder. , without the irritating smell of propionate, is a new type of food and feed antifungal agent with high quality and low price.

Sodium diacetate is widely used in medicine, food, tobacco, feed, fruit preservation and other fields. Adding sodium diacetate to pellet feed can increase the nutritional value of the feed, improve protein utilization and dairy cow milk protein content, and promote the growth of poultry. Adding it to aquatic feed can effectively prevent the spread of similar diseases and improve fish survival rates. When sodium diacetate is used in food, it can participate in the metabolism of the human body while preserving freshness, and will not harm human health. In addition, the addition method of sodium diacetate is more convenient and flexible, and spraying, dipping, and direct addition can all work.

Sodium diacetate is a substance that does not have an allowable daily intake (ADI). It is the safest antifungal preservative currently known. It has been designated as a recognized safe substance by the U.S. Food and Drug Administration and is a hygienic standard for the use of food additives in my country. GB2760-1996 has also approved its use in cereals, soy products and puffed foods. As national health awareness increases and the understanding of food additives continues to deepen, sodium diacetate, which is highly safe and harmless to the human body, will be more widely used in the field of food preservation and preservatives.

Driven by market demand, the number of domestic sodium diacetate production companies continues to increase. At present, domestic sodium diacetate production companies mainly include Lianyungang Nuoxin Food Ingredients Co., Ltd., Jiangsu Runpu Food Technology Co., Ltd., Shanxi Zhaoyi Chemical Co., Ltd., Qingdao Baichuanda Technology Co., Ltd., Jiangsu Kelunduo Food Ingredients Co., Ltd. Shandong Longchang Huarui Biotechnology Co., Ltd., Harbin Jinfulai Technology Development Co., Ltd., etc.

Industry analysts said that sodium diacetate, as a new antifungal agent and improver with stable properties, high safety and good performance, It is widely used in various fields, with the food and feed industry being the main demand side. As citizens pay more attention to food safety and the state strengthens supervision of food additives, the sodium diacetate industry has good development prospects.
