North China, Huanghuai, Northeast and Northwest China are the main corn producing areas in China, and they are also the regions with the highest concentration of corn starch production capacity. Corn starch is the main raw material for the production of monosodium glutamate, and the factory is built in the raw material area, the supply is abundant and the transportation cost is greatly reduced, which is also the reason why there are many monosodium glutamate enterprises in Shandong and other places. Linghua was born in Jining, Shandong, from the production of corn starch, to overcome microbial fermentation technology, and then to the deep processing and production of glutamic acid technology leap, Linghua step by step to go steadily.
 
Linghua was founded in 1979 as a township enterprise making starch. Taking advantage of the spring breeze of reform and opening up, Linghua carried out large-scale product structure adjustment and began to produce monosodium glutamate products in 1991. In 1993, Linghua brand monosodium glutamate won the honor of banquet in the Great Hall of the People with excellent quality, and was rated as "China Famous Trademark" and "China Famous Brand Product". Linghua has successively merged and reorganized 8 state-owned enterprises, and its products have also expanded to condiments, amino acids, organic fertilizers and other fields.
 
Because Jining's freshwater resources account for one-sixth of Shandong Province and are an important water source and transit point for the South-to-North Water Diversion, the water environment in the region is strictly required. In 2015, Linghua implemented the integration of modern agricultural seed and marketing, first planted corn, and then refined into monosodium glutamate and other products, and the waste liquid in monosodium glutamate production was converted into organic fertilizer, which was applied to agricultural planting, recycling resources, and the production capacity of monosodium glutamate ranked among the best.
 
There are two types of monosodium glutamate according to salt and unsalted. Salt-free monosodium glutamate is general monosodium glutamate, and the main component is more than 99% monosodium glutamate; Salt monosodium glutamate is also salt monosodium glutamate, which is made by mixing 80% monosodium glutamate with refined salt, and the amount of salt should be reduced when used. Linghua monosodium glutamate can also be bought in general small shops, the price is basically the same as Fufeng, and most of its products are also exported to the international market.
