微波条件下纸包装油墨中增塑剂向食品（模拟物）的迁移

研究纸张印刷油墨中4 种增塑剂（3 种邻苯二甲酸酯类增塑剂和近年流行的环保增塑剂乙酰基柠檬酸三丁酯）向食品模拟物Tenax和奶粉的迁移,考察其在110、250、440、600、900 W微波功率下的迁移行为,探讨迁移影响因素,并与常规条件下的迁移行为做比较。结果显示在一定条件下微波功率越高,迁移量越大;且迁移行为受增塑剂的分子质量、极性等性质的影响;常规条件下的迁移影响因素也适用于微波条件。     

控制好水性柔印油墨三大性能 提高纸张印刷品质

<正>目前柔印中常用的油墨包括水性油墨、UV油墨和醇溶性油墨三大类,纸张类承印材料柔印中主要以水性油墨为主。相对于UV油墨和醇溶性油墨,水性油墨在使用成本和绿色环保方面无疑更具优势。我公司长期致力于直接接触食品的纸包装印刷业务,自2000年以来一直采用水性柔印油墨印刷,日常生产中遇到的一些印刷质量问题,和水性柔印油墨的性能有着密切的关系。经过多年的生产实践和经验积累,笔者对纸张印刷用水性柔印油墨的性能及其

UV油墨光引发剂EDB在食品软包装中的迁移分析

为研究UV油墨光引发剂4-二甲氨基苯甲酸乙酯(EDB)在食品软包装中的迁移行为,制作了实际印刷、直接污染和蹭脏污染三种包装试样,分别以3%(w/v)乙酸、10%(v/v)乙醇和95%(v/v)乙醇作为酸性、酒精类和脂类食品模拟液,研究了EDB的迁移和残留行为。结果表明,光引发剂EDB在三种包装试样中都发生迁移。在三种食品模拟液中,EDB向95%乙醇中的迁移量最大,且初始迁移速率最快,说明EDB更容易向脂类模拟物迁移。温度越高,迁移量越大,达到平衡的时间越短。

Migration of plasticizers from printing inks into foods

It has been demonstrated that on storage of a tightly wound reel of polypropylene packaging film, specially printed for experimental purposes, transfer can occur of components from the ink on the outer surface of the film on to the inner food contact surface. For dicyclohexyl phthalate this transfer amounted to 6% of the total amount of plasticizer available in the printing ink system. It was subsequently shown for confectionery and snack food products wrapped in commercially printed polypropylene films that plasticizers only present in the printing ink migrated into the foods. The migration of plasticizer increased with storage time of the wrapped product; for dibutyl phthalate, for example, levels increased from 0.2 to 6.7 mg/kg over the period from 0 to 180 days storage of a chocolate-coated confectionery product. A small retail survey (47 samples) of confectionery, snack products and biscuits wrapped in printed polypropylene film showed the presence of one or more plasticizers at levels from 0.02 to 14.1 mg/kg for dibutyl phthalate, from less than 0.01 to 18.6 mg/kg for dicyclohexyl phthalate and from less than 0.01 to 1.8 mg/kg for di(2-ethylhexyl) phthalate. In all cases there was a good correlation between the plasticizers found in the printing ink from the film and those in the food. Wide variations were found, however, in the amounts and types of plasticizers used in printed packaging of the same brand of retail food product purchased from different regions of the country.

Migration analysis and health impact assessment of phthalates in takeaway food packaging materials

Plasticizers are commonly utilized as packaging additives in the food service industry. The takeaway food sector provides convenience to consumers, but also raises the risk of human exposure to plasticizers. The goal of this study is to determine the amount of phthalates in takeaway food packaging and compare the migration amounts under various situations. A comprehensive health impact assessment of phthalates was conducted to provide the evaluation of human's daily exposure to phthalates. The results revealed that five phthalates (di (2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), diethyl phthalate (DEP), dimethyl phthalate (DMP), dibutyl phthalate (DBP)) could be detected in n-hexane extract of plastic food packaging materials at room temperature. High amount of phthalates was correlated with high temperature or in an oily food simulant solvent. Phthalate contents in dietary exposure did not surpass the concentration that could represent a risk to human health, based on the dietary exposure evaluation.     

Phthalate Esters in Foods: Sources,Occurrence, and Analytical Methods

ABSTRACT: Phthalates are a group of diesters of ortho‐phthalic acid (dialkyl or alkyl aryl esters of 1,2‐benzenedicarboxylic acid). Higher‐molecular‐weight phthalates, such as di‐2‐ethylhexyl phthalate (DEHP), are primarily used as plasticizers to soften polyvinyl chloride (PVC) products, while the lower‐molecular‐weight phthalates, such as diethyl phthalate (DEP), di‐n‐butyl phthalate (DBP), and butyl benzyl phthalate (BBzP), are widely used as solvents to hold color and scent in various consumer and personal care products. Phthalates have become ubiquitous environmental contaminants due to volatilization and leaching from their widespread applications, and thus contamination of the environment has become another important source for phthalates in foods in addition to migration from packaging materials. Human exposure to phthalates has been an increased concern due to the findings from toxicology studies in animals. DEHP, one of the important and widely used phthalates, is a rodent liver carcinogen. DEHP, DBP, BBzP, and several phthalate metabolites, such as monobutyl phthalate, monobenzyl phthalate, and mono‐(2‐ethylhexyl) phthalate, are teratogenic in animals. Since foods are the major source of exposure to phthalates, information on levels of phthalates in foods is important for human exposure assessment. The objective of this review is to identify the knowledge gaps for future investigations by reviewing levels of a wide range of phthalates in a variety of foods, such as bottled water, soft drinks, infant formula, human milk, total diet foods, and others, migration of phthalates from various food‐packaging materials, and traditional and new methodologies for the determination of phthalates in foods.     

Estimated daily intake of plasticizers in 1-week duplicate diet samples following regulation of DEHP-containing PVC gloves in Japan

Duplicate hospital diet samples obtained over 1 week in 2001 were analysed to estimate the daily intake of plasticizers and the results were compared with those obtained in 1999. The plasticizers quantified in this study were: dibutyl phthalate, butylbenzyl phthalate (BBP), di(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DINP), di(2-ethylhexyl) adipate (DEHA), diisononyl adipate (DINA) and O-acetyl tributyl citrate (ATBC). Dipropyl, dipentyl, dihexyl and dicyclohexyl phthalate were also analysed but not detected. The analytical procedure for this follow-up study was essentially the same as in the previous one. Detection limits were 0.1-15.6 ng g^-1 for each plasticizer. One-week duplicate diet samples provided by three hospitals in three remote prefectures of Japan were analysed as individual meals. DEHP was detected at 6-675 ng g^-1 in 62 of 63 meals, significantly lower levels compared with those detected in 1999. Levels of DEHA and DINP also decreased. The mean intake of plasticizers estimated from all samples was 160 μg DEHP day^-1, 12.5 μg DEHA day^-1, 4.7 μg DINP day^-1 and 3.4 μg BBP day^-1. Levels of DINA were relatively high in meals from one hospital: in those meals, the average daily intake was 1338 μg day^-1. Those of ATBC were also higher in meals from another hospital: the average daily intake was 1228 μg day^-1. The sources of DINA and ATBC can be cling-film or sausage packaging.     

Occurrence of phthalates in different food matrices: A systematic review of the main sources of contamination and potential risks

This systematic review aimed to investigate the occurrence of phthalates (phthalic acid esters [PAEs]) in different food matrices, as well as report the main sources of PAEs in food, the potential risks to the population, and the factors that influence its migration from food contact materials (FCMs) to food. Nineteen PAEs were identified, including di-(2-ehtylhexyl) phthalate (DEHP), dibutyl-phthalate (DBP), benzylbutyl phthalate (BBP), diisononyl phthalate (DINP), and diisodecyl phthalate (DIDP) in fruits and vegetables, milk and dairy products, cereals, meat, fish, fat and oils, snacks, condiments and sauces, miscellaneous, and baby food. Fifty-seven values of PAEs were above the legal limits of countries. DEHP is the PAE with the highest incidence, with maximum concentrations above the specific migration limit (SML) for milk and dairy products, oils and fats, fish, cereals, condiments and sauces, meat, and fruits and vegetables. The risk of exceeding the tolerable daily intake (TDI) was high for DEHP and DBP in fish, fat and oils, cereals, and milk and dairy products for children and adults. Fat and oils are the most critical food for DEHP, DBP, BBP, and DINP. Comparing the estimated daily intake (EDI) with the TDI, there was a risk for “milk and dairy products” in adults and for “cereal and cereal products” in children concerning DEHP. “Cereal and cereal products” presented a risk in children and adults concerning DBP. The “fat and oils” category presented a risk in children and adults about DBP and DINP. Temperature, contact time between food and the FCM, fat percent, and acidity positively correlate with the PAE's migration. The contamination occurs in many steps of the production chain.     

纳米银-聚乙烯复合包装中银对2 种抗氧化剂向食品模拟物迁移的影响
