Parchment Paper
Parchment paper, or vegetable parchment, is a cellulose-based composite that has been processed to give it additional properties like non-stickiness, grease resistance, and resistance to humidity. It is commonly used in baking as a disposable non-stick, grease resistant surface. It should not be confused with waxed paper, which is paper that has been coated in wax. Parchmentization of paper Vegetable parchment paper is made by running sheets of paper pulp through a bath of sulfuric acid (a method similar to the way tracing paper is made) or sometimes zinc chloride. This process partially dissolves or gelatinizes the paper. This treatment forms a sulfurized cross-linked material, with high density, stability, heat resistance, grease resistance, water resistance, no loose fibers as well as low surface energy — thereby imparting good non-stick or release properties. The treated paper has an appearance similar to that of parchment and, because of its strength, is sometimes u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
En Papillote
''En papillote'' (; French for "enveloped in paper"), or ''al cartoccio'' in Italian, is a method of cooking in which the food is put into a folded pouch or parcel and then baked. This method is most often used to cook fish or vegetables, but lamb and poultry can also be cooked ''en papillote''. It is a combination cooking method of baking and steaming. Method The parcel is typically made from folded parchment paper, but other material, such as a paper bag or aluminum foil, may be used. The parcel holds in moisture to steam the food. The pocket is created by overlapping circles of paper or foil and folding them tightly around the food to create a seal. The moisture may be from the food itself or from an added moisture source, such as water, wine, or stock. The choice of herbs, seasonings and spices depend on the particular recipe being prepared. The parcel can be opened at the table to allow people to smell the aroma when it opens. Regional and local variations Asia With l ...

Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, Textile, rags, poaceae, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and Housekeeping, cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 Common Era, CE, by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baking
Baking is a method of preparing food that uses dry heat, typically in an oven, but can also be done in hot ashes, or on hot stones. The most common baked item is bread but many other types of foods can be baked. Heat is gradually transferred "from the surface of cakes, cookies, and pieces of bread to their center. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer center".p.38 Baking can be combined with grilling to produce a hybrid barbecue variant by using both methods simultaneously, or one after the other. Baking is related to barbecuing because the concept of the masonry oven is similar to that of a smoke pit. Baking has traditionally been performed at home for day-to-day meals and in bakeries and restaurants for local consumption. When production was industrialized, baking was automated by machines in large factories. The art of baking remains a fundamental skill and is important for nutrition, as ...

Release Liner
A release liner or ''release paper'' is a paper or plastic-based film sheet (usually applied during the manufacturing process) used to prevent a sticky surface from prematurely adhering. It is coated on one or both sides with a release agent, which provides a release effect against any type of a sticky material such as an adhesive or a mastic. Release liners are available in different colors, with or without printing under the low surface energy coating or on the backside of the liner. ''Release'' is separation of the liner from a sticky material; ''liner'' is the carrier for the release agent. Industry segmentation Globally there are between 400 and 500 companies involved in making or dealing with release liner products on an industrial scale. In general there are two types of companies which are manufacturing release liner. Liner producer Commercial coating companies deal with a lot of different end uses of this industry. They provide unique solutions to their customers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greaseproof Paper
Greaseproof paper is paper that is impermeable to oil or grease, and is normally used in cooking or food packaging. It is usually produced by refining the paper stock and thus creating a sheet with very low porosity. This is then passed between hard pressure rollers (supercalendered) to further increase the density, creating a paper called glassine. The glassine is treated with starches, alginates or carboxymethyl cellulose (CMC) in a size press to fill pores or treat the paper chemically to make it fat repellent. Basis weights are usually 30–50 g/m2.
