Definition. Except for table margarine, plasticized edible fats are usually packaged and immediately transported to and stored in a constant temperature room for 24— 72 h. This quiescent heat treatment is referred to as tempering. It is generally agreed that tempering should be conducted at about 27°C (80°F) and that it improves...

Biodegradable films made from edible biopolymers from renewable sources could become an important factor in reducing the environmental impact of plastic waste. Proteins, lipids, and polysaccharides are the main biopolymers employed to make edible films and coatings. Which of these components are present in different proportions and determine the properties of the material, as a barrier to water vapor, oxygen, carbon dioxide, and lipid transfer in food systems (Gomez-Guillen et al. 2002 and 2009).

PET is the plastic used to package the majority of soft drinks. It is also used for some liquor bottles, peanut butter jars, and edible-oil bottles. About one-quarter of plastic bottles are PET. PET bottles can be clear they are tough and hold carbon dioxide well.

The extraction pressures and temperatures were varied, ranging from 100 to 310 bar and 30 to S0°C. The soluble components were generally collected in a separator at 343 bar/40°C Edible beef tallow of commercial grade was obtained from Anderson Qayton/Humko Products, Inc. (Memphis, TN) and melted at S0°C, mixed, subdivided into smaller plastic containers with 200 g each in weight, and stored at -27°C until used. The procedures mentioned above were followed for the extraction of 100 g beef t ow. 

Ethanol and aqueous ethanol mixtures play important roles as food simulants for the determination of migration of substances from packaging into foods. Depending on the polarity of the plastic one can use pure ethanol (for nonpolar plastics) or aqueous ethanol mixtures up to 50/50 % (for polar plastics) as alternative simulants to edible oils (see Chapters 9,10 and 11). The estimation of partition coefficients in poly-mer/simulant systems is consequently of practical importance. It is possible to do this for polyolefins in contact with alcohol and aqueous alcohol mixtures with the help of an equation analogous to Eq. (4-100) (Piringer, 1993) ... 

Example 7-7. Edible oil is stored in a plastic bottle with an external diameter of 10 cm and with a wall thickness of 2 mm. What percent of the antioxidant contained in the plastic bottle migrates after a) 100 days and b) after 2 years into the oil when the antioxidant has a diffusion coefficient of DP = IE-11 cm2/s ...

The substituted phenols and cresols constitute about half the total volume of this group. Para-t-butylphenol is produced by the alkylation of phenol with isobutylene. The principal applications for this derivative are in the manufacture of modified phenolic resins for the rubber industry and in surface coatings. BHT is obtained from isobutylene and p-cresol. Technical-grade BHT is an antioxidant for plastics and elastomers, and is a gum inhibitor in gasoline. Food-grade BHT is an antioxidant in edible oils, preserves, and many other foods. 2,6-Di-t-butylphenol is used to produce a wide range of plastics additives, antioxidants, and gasoline additives.
