Increasing pressure to bring novel specialty compounds to market has initiated the automation of laboratory reactors to perform controlled experiments at laboratory scale which can be easily scaled-up. Product and process developments in the shortest time to produce the first kilogramme of compound for commercial evaluation is of utmost importance. The LabMax reactor is a … Read more
Polymorphism is defined as the ability of a chemical compound to form different crystalline structures. The three basic polymorphic forms of fats are !, “’ and “. The !-form is the least stable and has the lowest melting temperature and the “-form the most stable with the highest melting temperature. The “’ has intermediate characteristics … Read more
POB-HIE is designed as a high fat energy formulation from refined palm oil products. This fat is specially made to provide energy to support efficient growth of starter and finisher broiler chicken. MPOB-HIE is scientifically designed and formulated to replace crude palm oil (CPO) in the manufacture of total mixed ration M (TMR) of broiler … Read more
BaP is a member of a class of compounds known as PAHs which generally occur as complex mixtures and not as single compounds (Figure 1). PAHs are primarily by-products of incomplete combustion. These combustion sources are numerous and include natural sources such as wildfires, industrial processes, transportation, energy production and use, food preparation, smoking tobacco … Read more
This test method describes a method for the determination of hydrocarbons (n-alkanes) in vegetable oils and fats using gas chromatography-mass 297 spectrometric (GCMS) detection. Vegetable oils may be contaminated by mineral fuel oils (dieseloil) due to the use of transport/storage facilities which are not strictly for transport/storage of food-grade, or due to other reason. The … Read more
The method involves the extraction of chlorpyrifos with hexane acetonitrile. Chlorpyrifos is preferentially partitioned into the polar acetonitrile layer while the bulk of the lipids remains solubilized in the non-polar hexane. The acetonitrile extract are subjected to clean-up procedure through a silicic acid column. The chlorpyrifos is analysed by gas chromatography equipped with an electron … Read more
