Packaging butter

Primary receivers buy butter from manufacturers at spot prices (plus possible premiums) and sell to several types of customers. Print butter (packaged in pound... 

Margarine and butter contain fat plus water and water-soluble ingredients, eg, salt and milk soHds that impart flavor and color to the product. Generally these products are distributed at refrigerated temperatures to retain their quaHty. Greaseproof packaging, such as polyethylene-coated paperboard, aluminum foil/paper, parchment paper wraps, and polypropylene tubs, is used for butter and margarine (see Dairy substitutes). 

Stearic acid is the most common of the long-chain fatty acids. It is found in many foods, such as beef fat and cocoa butter. It is widely used as a lubricant in soaps, cosmetics, food packaging, deodorant sticks, and toothpastes. It is also a commonly used softener in rubber. 

P.Y.114 is primarily supplied to the printing ink industry, where it is used especially for packaging inks. The pigment is utilized to produce prints at reasonable cost, especially where exceptional fastness, as provided by P.Y.83, is a minor consideration. Prints made from P.Y.114 are not entirely resistant to a number of organic solvents, including the standard DIN 16 524 solvent mixture, paraffin, and butter but P.Y.114 prints are soap, alkali, and acid resistant. The fact that the pigment does not withstand a temperature of 140°C and is not stable to sterilization excludes P.Y.114 from use in metal deco printing. 

In applications where the pigment is fast enough to solvents to satisfy the requirements, it may also be used for offset, packaging gravure, and flexo printing inks. The resulting prints are soap, alkali, and acid resistant. They are not completely fast to paraffin and quite sensitive to butter and a number of other fats. P.R.14 prints are not fast to clear lacquer coatings and may not be sterilized. Heat stabil-... 

P.R.88 is also used for printing inks. Its red-violet shade is especially used for printing inks which are to be targeted for packaging, posters, and other special purposes. The prints are entirely fast to organic solvents, plasticizers, and packaged goods, such as butter and soap. P.R.88 prints are fast to alkali and acid, heat stable up to 200°C, and fast to sterilization. 

P.R.83, listed under Constitution No. 58000 1, continues to be used only in the USA. The pigment affords brilliant, bluish shades of red. Traces of iron as an impurity adversely affect the full shades and shift the color towards duller and bluer shades. The pigment is not fast to common organic solvents, especially to esters and ketones. It therefore lacks stability to overcoating. Its lightfastness, particularly in tint, is poor. P.R.83 is used in paints for toys, in packaging printing inks, especially for soap and butter, and in artists colors. 

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.

Before butter is packaged, it is typically worked to achieve a desirable texture (Joyner, 1953). This step also helps to disperse the water and salt in... 

Oxygen scavengers can be used to reduce the 02 content in packaged milk powder but this approach may not be cost-effective (Zimmerman et al., 1974). Another approach to reducing the 02 content in the package involves using H2 in the presence of a palladium or platinum catalyst. Although the use of several antioxidants is permitted in the manufacture of edible oils, fats and butter, their use in milk powder is prohibited.

In 2004, Treofan GmbH developed a metallised version of its PLA biodegradable film that reduces permeability aromas, oxygen and water. The metallised Biophan PLA film is said to be suitable for packaging fatty foods such as butter and cheese, as well as for confectionery, where the mirror-like finish adds a decorative feature to the barrier properties. The metallised film meets both EU and US, Food Drug Administration food contact requirements. 

For studies carried out investigating the nature of foodstuffs, MPPO was replaced by wheat biscuit breakfast cereal (representing a dry foodstuff with low fat content), savoury biscuits (dry foodstuff with high fat content), butter (fatty foodstuff) or orange juice (acidic foodstuff). PP film was used as the primary packaging material for the studies with foods. Conclusions from the studies were as follows ... 

Multiple butter fat products, including butter oils, anhydrous butter fat, butter fat-vegetable oil blends, and fractionated butter fats, are manufactured around the world today. In the past, butter fat in the form of butter was the primary preservation technique. Today, the preferred preservation method involves the processing of butter fat to the anhydrous butter oil state, then hermetically packaging under nitrogen to substantially increase the shelf life and reduce the incidence of degradation.
