How long is the shelf life of brown sugar?

The shelf life of brown sugar is generally around 18 months, and the shelf life of bulk brown sugar will be shorter than 18 months because it is not sealed.

Brown sugar refers to the finished sugar of sugar cane and honey, which is made by squeezing and concentrating sugar cane. The famous brown sugar producing areas are Gongcheng Yao Autonomous County in Guilin, Guangxi, Yunnan and other places. If it is brown sugar in sealed package, the date of production, shelf life and storage method will generally be written on the package.

Generally, it is not opened, and it is not stored in special environments such as excessive humidity, high temperature and high acidity. It can be eaten according to the specified shelf life. Bulk brown sugar is directly exposed to the air because it is not sealed, which is greatly affected by humidity, temperature and ventilation. The shelf life of bulk brown sugar is shorter than that of sealed brown sugar, so it is necessary to observe whether it goes bad before eating.

Production technology of brown sugar

Lime method refers to the clarification of sugarcane juice with lime as the main clarifier. As early as 400 years ago, the clarification method of this lime method was recorded in China Song's Tiangong Wu Kai. Because lime is a raw material with easy access to materials, low cost and simple production process, after hundreds of clarifiers have been tried, lime is still the most commonly used one in sugar industry.

The overall clarification effect of lime method is not ideal, and the impurity removal rate is not high. The purity of sugarcane juice has not changed obviously before and after treatment. Therefore, in our country, the simple lime method is usually only used to produce some low-quality sugar products, such as brown sugar, potato chips sugar, brown sugar powder and so on. In foreign countries, raw sugar is usually produced by lime method, and the raw sugar is further refined and purified after it is obtained.
