osmotic dehydration under discontinuous reduced pressure is one of the new methods of preparation fruits and vegetable processing with in view of good health. processing of foods at high temperatures used to cook them can cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans-fat is removed. the low temperatures employed in this method resulted i...

frying is an important unit operation used widely both in domestic and industrial cooking. reduced pressure (vacuum), microwave, deep fat and pan frying are the most important methods of food frying. final product has good organoleptic quality (colour, texture, and flavour). the accuracy of the knowledge of mass transfer parameters (effective diffusivity coefficient, dimensionless biot number a...

Comparative frying studies on the processing of extruded product were conducted under intermittent and continuous frying conditions using two separate frying systems, i.e batch and pilot scale continuous fryers, respectively. Thermal resistance of palm olein were assessed for a total of 5 days of frying operation at 155°C - the unconventional frying temperature gave the product moisture content...

ABSTRACT: Vacuum deep-fat frying is a new technology that can be used to improve the quality attributes of fried food because of the low temperatures employed and minimal exposure to oxygen. In this paper the effect of frying process parameters, namely frying time, frying temperature and pressure on the quality factors of fried kiwi slices was studied. A laboratory scale vacuum frying apparatus...

Deep-fat frying performed at high temperatures under atmospheric pressure is a common method of preparing dishes in Senegalese culinary practices. This operation can lead to deterioration of physical, chemical, nutritional and sensory properties of oil, which affects its frying performance. It also results in the production of volatile products such as aldehydes and non volatile fraction which ...
