Direct/indirect food contact

Rosin has a low order of toxicity foUowing ingestion or skin contact. Rosin and its numerous derivatives have a number of permitted food packaging and other direct and indirect food contact uses throughout the world. Sanctioned uses appHcable in the United States are outlined in U.S. Food and Dmg Administration (U.S. FDA) Regulations (2). Material Safety Data Sheets (MSDSs) for specific rosins and thein derivatives should be consulted before thein use. 

Polyterpenes enjoy a number of FDA approvals. They are not only suitable for adhesives with indirect food contact, but also for use in both chewing gum and in films that will have direct food contact. Their higher price compared to petroleum-derived equivalents has resulted in a significant decline in usage over the past 10 years, except where FDA approvals dictate their usage. 

One differentiates resins into those for direct food contact use like lacquers for baking forms and paper coatings and those resins for indirect food contact use like grills, warming plates and others. 

Triacetin is approved by the FDA for direct and indirect food contact applications. 

This product does not have FDA approval for direct or indirect food contact. It is not considered to be hazardous for shipping purposes. 

Regulatory Approval " EVAL resins may be used in applications involving direct food contact as outlined by the FDA regulations, 21 CFR, Section 177.1360. EVAL resins may be used for indirect food contact (adhesive resins) as outlined in CFR, Section 175.105. EVAL resins comply with food additive regu-... 

C12 to C20, primarily Ci6 to ( is), used as surface lubricants in the manufacture of food-contact articles. The method, which uses ethyl palmitate (Eastman Chemicals No. 1575 Red Label) as an internal standard, has been validated at 200 ppm total FAME [185]. Other FAME standards (methyl palmitate, methyl stearate, methyl oleate, methyl linoleate and methyl linolenate) are available (Applied Science Laboratories) [116], Worked out examples of additive determinations are given in the Food Additives Analytical Manual [116], which also describes a great many of indirect food additives, such as BHA, BHT, TBHQ, l-chloro-2-propanol, DLTDP, fatty acid methyl esters, w-heptyl-p-hydroxybenzoate, propyl-gallate, sodium benzoate, sodium stearoyl-2-lactylate, sorbitol and phenolic antioxidants. EPA methods 606 and 8060 describe the CGC separation of phthalate esters (direct injection) (cf. Figure 4.2). 

These recommendations are intended to amplify and explain the statutory chemistry requirements for indirect food additive petitions. The science and technology of food-packaging and food-contact articles as well as the scientific basis for evaluating exposure to indirect food additives are continually evolving. Therefore, for the most current information go directly to http // vm.cfsan.fda. gov/ drns/opa-cg5. html... 

It is furthermore noted that the TTC concepts, including the structure-based approaches, are derived from databases covering substances used as direct and indirect food additives, pesticides, and industrial chemicals, and cover toxic effects related to systemic exposure to these chemicals. In addition, it is underlined that TTC has not been developed for endpoints associated with direct contact such as irritation or sensitization. 

The term food additive is used to cover any substance that is expected to become a component of human food. This covers substances intentionally added to food for their nutritional, chemical, or physical benefits (e.g., colorants and gelling agents) and substances used in the manufacture or packaging of foods (i.e., food contact substances, formerly known as indirect food additives ). The US Federal Food, Drug, and Cosmetic Act defines food additives as substances whose intended use results or may reasonably be expected to result, directly or indirectly, in its becoming a component of food or otherwise affecting the characteristics of food. ... 

The use of antioxidants in foods, pharmaceuticals, and animal feeds (direct feed additives), as well as their use in food-contact surfaces (indirect additives) is closely regulated by the governments of several countries. Antioxidants are approved only after extensive extraction, toxicological, and feeding studies. The list is relatively limited. Although antioxidants have been used for several decades and some occur naturally in food substances, intensive lesearch in continuing, pardy accelerated by the growing use of unsaturated oils in numerous food products. 

The purpose of this article is to consider the nature of soils, how soils are contaminated by human activities, how these contaminants are transported and transformed in the soil column, and the types of human activities that could result in human exposure to soil contaminants. Soils are complex systems that exist at the interface among atmosphere, biosphere, hydrosphere, and lithosphere. A true soil includes gas, water, mineral, and organic components. Potential human contacts with soil can result in inhalation, ingestion, and dermal uptake of soil contaminants through both direct and indirect exposure pathways. The magnitude and persistence of exposure depends not only on the level of soil contamination, but also on the physical and chemical properties of soil, the chemical properties of the contaminant, and the frequency and duration of human activities such as occupational and recreational activities or use of home-grown food, which result in direct and indirect soil contacts. Toxicologists should be aware of the complex nature of soils, of the potential of soil contamination, and of types of direct and indirect contacts that human populations have with soil. 

Adimoll DO can be used when regulations and recommendations governing food contact applications need to be met. The FDA has approved this material to be used to make plastic packaging as indirect food additives (substances which may come in contact with food as part of packaging or processing equipment but are not intended to be added directly to food). 

Active food packaging is a film or coating that is directly or indirectly in contact with any food surfaces to increase the shelf life or improve the quality of the packaged food. The big classifications fall under either oxygen-scavenging or antimicrobial but other upcoming types such as ethylene-scavenging, moisture absorbers, taint removers, and color and flavor enhancers have also been identified.
