Introduction: The objectives of this study were to determine the air curtain velocities of hood to capture and contain the splashing oil. The optimal flow of air curtain velocities is introduced to apply cooking by pan frying. Methods: At the first stage, palm olein oil was poured to a pan and fried at constant temperature of 180 ± 5 °C for 140 seconds. In the meantime, the 4-air flows, which w...

introduction: frying is one of the most popular cooking methods. however, harmful substances are created during the frying process, with the stability of oil negatively affected. this study evaluates the stability of fatty acid content of several cooking and frying oils available on the iranian market during the process of frying. materials and methods: samples from 5 different frying oils and ...

Gas cooking is a significant source of airborne particles indoors. In order to assess health risk due to exposure from indoor particulate air pollution and to identify effective control strategies, data on size-differentiated aerosol particles released from different cooking methods are critically needed. In this study, controlled experiments were carried out in a domestic kitchen using a scann...

In present study the effect of different pre-frying temperatures in sunflower oil on physical and chemical characteristics of silver carp fish nuggets (Hypophthalmichthys molitrix) were studied. After prepared, the fish nuggets were pre-fried in sunflower oil heated to 150, 170 and 190°C. The measurements included: the proximate composition (protein, moisture, fat and ash), physical experiments...

New conversion technologies of used edible oils and waste animal fats into a biofuel appropriate for use in standard diesel engines have been developed, taking into consideration environmental requirements and improvement in the economics of current trans-esterification technologies. The variation in the properties of substrates made from used rape oil after treatment with mixed adsorbents (act...

Background There has been an alarming increase in the dumping of Hong Kong’s municipal solid waste (MSW), predominantly food waste, in landfill (9,547 tonnes of MSW per day in 2013) [1]. One way of promoting an environmentally friendly method of minimising food waste is to turn the waste into energy by producing biodiesel from waste cooking oils. Biodiesel is a biodegradable fuel that can be ma...

BACKGROUND Crispness is an important characteristic to be controlled in deep-fat fried products. The physical state of food polymers influences the development of cellular structure and textural qualities of fried food. Glassy state is believed to play an important role in the mechanical properties of low-moisture food. Therefore, an understanding of the physicochemical phenomena in the develop...

The influence of oxidized frying oil (OFO) on the guinea pig hepatic microsomal xenobiotic-metabolizing enzyme system in the presence of different amounts dietary vitamin C was investigated. Weanling male guinea pigs were divided into four groups and were fed 15% oxidized frying oil diets supplemented with vitamin C at 300, 600, or 1,500 mg/kg (experimental diets) or a control diet that contain...

Soybean oil was continuously hydrogenated in a slurry system to investigate the effects of linolenate content and additives on cooking oil performance. Room odor evaluations carried out on oils heated to 190 C after frying bread cubes showed that the oils hydrogenated with Cu catalyst to 2.4% linolenate (Cu-2.4) and with Ni catalyst to 4.6 linolenate (Ni-4.6) had a significantly lower odor inte...
