Soy sauce has been always the essential seasoning for Eastern since thousands of years ago. By the trend of living standard upgrading and the concept of return to natural becoming popular, people change their material to produce soy sauce, from GMO soybean powder, Non-GMO whole soybean, into organic certificated soybean & wheat. Such trend grows soon in recent years little by little. Besides, improvements for high sodium, salty, function of soy sauce, which is always the target to reach for soy sauce maker. Hence, this experiment puts Lycium barbarum LINNAEUS, divided by adding different ratio, 12%, 18%, and 23%, organic soybean, and organic wheat with bacterium together to cultivate and ferment. We analysis it by sampling during the fermentation period of 30, 90, and 150 days to research the influences of adding Lycium barbarum Linnaeus.
Result: we inspect the content of total nitrogen and formol nitrogen: Since we add Lycium barbarum LINNAEU of 12%, 18%, and 23% ratio in quantity, and deduct the quantity from soybean accordingly. It is caused quantity decreasing progressively of soybean to the other contrast team. Inspection of organic acid : For adding 12% and 18% of Lycium barbarum LINNAEUS, the content of organic acid will increase by the extension of fermentation time; For the one which adding 23%, the content doesn't make big difference. The highest content is from 90 days of fermentation for the contrast team. Inspection of nucleic acid: The content of four samples will increase by the extension of fermentation and there is no big difference till and after 150 days. Inspection of total sugar: The content of the four samples is at the highest till 30 days, then it will low down by the increasing of days. Inspection of free fatty acid and reducing sugar: The content reaches the most till 90 days for the four teams and then it will decrease progressively. Sensory evaluation inspection: The best one is the team adding 18% Lycium barbarum Linnaeus. The color, aroma, flavor, taste, and whole image are most close to the contrast team. The conclusion for this experiment presents that the best quality is the one adding 18% Lycium barbarum Linnaeus.
