of high quality soy sauce production.

Using the modern strain technologies of cell-fusion and
gene-recombination, cultivating more enzymatic strain by
induced mutation, purification and auxiliary strengthening
of strain so as to attain more than 88% protein
usage rate during fermentation processing.

Using modern extraction and separation technology,
desiccating and granulating technology, micro encapsulating
technology to increase the added-value of the products.

Using enzyme engineering technology to enhance the
substance transformation during food production processing,
such as using cellulose enzyme to produce dissolvable
cellulose during the fermentation cycle engineering.

Application of food testing, such as using solidified enzymatic
technology to test food chemical ingredients rapidly and simply,
using gene engineering DNA fingerprint technology to identify
food raw materials and end-products.
