Embodiment 1

[0042] A safety evaluation method for bio-based food packaging materials

[0043] (1) The liquid-liquid extraction method of phthalates in four simulated liquids was optimized and established.

[0044]Use a rapid solvent extraction instrument (ASE300) to extract phthalates in bio-based food packaging materials. Specific steps: After the bio-based food packaging lunch box is pulverized by a mixer, accurately weigh 1.0 g (accurate to 1 mg). ), wrap it with filter paper and put it into the extraction pool (select a 66mL extraction pool); set the extraction temperature to 70°C, the static extraction time of 3min, the extraction pressure of 1500psi, the static cycle for 2 times, the rinse volume of 60%, and the nitrogen purge time of 120sec . After the extraction, the extract in the collection flask was poured into a 100 mL round-bottomed flask, and the extraction solvent was removed by rotary evaporation at 40°C. When there is about 2 mL of liquid remaining, stop the rotary evap...

Embodiment 2

[0049] A safety evaluation method for bio-based food packaging materials, the steps and methods are basically the same as those in Example 1, the difference is that the experimental temperature is 25°C.

Abstract

The invention relates to a safety evaluation method of a bio-based food packaging material. The safety evaluation method comprises the following steps: (a) optimizing an efficient extraction method of phthalic acid ester substances in the bio-based food packaging material; (b) selecting proper simulation liquid to respectively simulate water-based, acidic, alcoholic and fatty foods, and simulating the migration rule of phthalate substances in the use process of the bio-based food packaging material at different temperatures; the method has the beneficial effects that the method for rapidly extracting the plasticizer in the bio-based food packaging material is researched and established by taking the bio-based food packaging material as a research object; a proper simulation liquid is selected according to regulations in the national standard, and the migration rule of the phthalate substances in the bio-based food packaging material at different use temperatures is investigated, so that a foundation is laid for safety evaluation of the bio-based food packaging material in use; the method is of great significance in improving the quality of food packaging materials and safely and healthily developing the food packaging materials.

Description

technical field [0001] The invention belongs to the research field of biological-based food packaging materials, and relates to a safety evaluation method for biological-based food packaging materials. Background technique [0002] Exquisite food products are inseparable from packaging, and food safety is inseparable from packaging. With the continuous improvement of living standards, people's requirements for food products are getting higher and higher, and various food packaging products flood into the market. However, while food packaging brings convenience and convenience to people, it also brings many hidden dangers to food safety. In recent years, food safety incidents caused by food packaging have emerged in an endless stream. The plasticizers of plastic containers for liquor are seriously exceeding the standard, and the carcinogens of PVC plastic wrap and the ink contamination of baby milk packaging. [0003] At present, bio-based plastic lunch boxes are common in ...
