Although the White Dew solar term has passed, the weather in many places is still humid and hot. Recently, information about "soy sauce pests" has been popping up on online platforms. Why does soy sauce grow insects? What are the bugs in soy sauce? Can soy sauce with insects still be consumed? How should soy sauce be stored correctly? In response, the reporter interviewed relevant experts. What is the reason for soy sauce insect infestation? The reporter found through online searches that every summer, there are incidents of food insect infestation in Jiangxi, Guangdong, Guangxi, Zhejiang, Hunan and other places, covering soy sauce, sauces, fish, meals, dairy products, etc. Among them, soy sauce insect infestation is more frequent. Ruan Guangfeng, Deputy Director of the Kexin Food and Health Information Exchange Center, stated that the main reason for the emergence of pests in soy sauce is due to the lax sealing of the opened soy sauce, which was taken advantage of by a type of insect called the "sauce sesame fly". The "sauce sesame fly" usually appears in May and gradually decreases after October. Therefore, soy sauce is more susceptible to insects in summer and autumn. The "sauce sesame fly" prefers environments with temperatures ranging from 20 degrees Celsius to 30 degrees Celsius and humidity ranging from 60% to 90%, so most of the soy sauce insect infestations occur in the south. Experts have introduced that "sauce inferior flies" like to produce insects in sauce products such as bean paste and soy sauce, which is why the name of "sauce inferior flies" carries the word "sauce". It is understood that the "sauce sub fly" quickly finds food with high protein and amino acid content through its two antennae, and high-quality soy sauce is precisely rich in amino acids. The soy sauce left on the bottle cap, bottle body, and other parts during use can easily attract the "sauce like flies". If it's laying eggs, why can I directly see the worm? Ruan Guangfeng introduced that the breeding method of the "sauce Asian sesame fly" is quite unique, which is "egg viviparity", which means that the young eggs develop in the mother's body and directly produce insects when the mother produces. Therefore, in daily life, soy sauce is not exposed for a long time and no insect eggs are seen, but insects are found inside. At what stage does soy sauce produce insects? In response to the question of "since the insect eggs in soy sauce are hatched, is it possible that soy sauce comes with its own insect eggs and hatches into fly insects after opening the lid?" Famous Chinese seasoning expert Wu Ming said that this situation usually does not occur. The soy sauce that is normally sold in the market has formal production procedures and strict quality control. To ensure the quality of soy sauce, it must be filtered and high-temperature sterilized before filling. Therefore, under normal circumstances, soy sauce cannot contain insect eggs. The phenomenon of insect infestation in soy sauce is mostly caused during the use of soy sauce after opening. So, is it possible that the phenomenon of "soy sauce producing insects" is due to inadequate quality management or sterilization measures by the manufacturer, resulting in the soy sauce itself carrying the eggs of ordinary flies and hatching into adults? Ruan Guangfeng said that the eggs of ordinary flies cannot hatch in high salt liquid foods such as soy sauce, but the larvae directly produced by the "sauce subspecies" can survive and grow in high salt environments. Therefore, the fundamental reason for the emergence of insects in soy sauce lies in the "egg viviparous" breeding method where the "sauce subfamily fly" can directly produce larvae, while some consumers suspect that soy sauce itself carries fly eggs and hatches into adults, which is impossible to occur. Can soy sauce still be consumed with insects? "Insects indicate that soy sauce lacks technology and
