| Abstract: |
| The quality safety level and pollution degree of edible vegetable oil in Guangxi were monitored and evaluated. From 2016 to 2017, 3 821 edible oils were collected from 14 prefecture-level cities in Guangxi. The acid value, peroxide value, solvent residue of the leached oil, aflatoxin B1, total arsenic, lead and benzo(a)pyrene of edible oil were measured according to GB/T 5009 and evaluated according to GB 2716—2005. The results showed that the total qualified rate was 92.04%. The qualified rates of edible vegetable oils in 2016 and 2017 were 96.70% and 91.22% respectively, and the difference was statistically significant (P<0.05). In terms of edible vegetable oil varieties, the qualified rates of corn oil, sesame oil and other edible vegetable oils were 100%, 93.75% and 99.61%, respectively. The qualified rate of peanut oil was the lowest (87.83%). With the detection rate of 8.85%, aflatoxin B1 exceeding the limitation was the main reason for the unqualified peanut oil. From the packaging, the qualified rate of prepackaged vegetable oil (99.70%) was significantly higher than that of bulk (83.72%), the difference was statistically significant (P<005). The qualified rate of production and processing of the edible vegetable oil was the lowest (88.01%). There were higher qualified rates in the sampling detection of corn oil, sesame oil and other edible vegetable oils compared with peanut oil in Guangxi. It was necessary to strengthen sampling inspection, monitoring, supervision and management in peanut oil industry so as to gradually promote the safety level of edible vegetable oils in Guangxi by fulfilling responsibility of production operators, actively guiding rational consumption, deepening the special governance of small oil mills, and continuously enhancing research on quality and safety control technologies. |
