Deodoriser distillate

The valorisation of these side streams is illustrated by the conversion of the deodoriser distillate into biodiesel. Deodoriser distillate is dissolved in methanol in a weight ratio 1/1 and 5% (w/w) sulfuric acid is added and heated at 75 °C for 5 hours with stirring. Under these circumstances the FFA are esteri-fied and the remaining monoglycerides are mostly undergoing a transesterili-cation giving FAME. 

The byproducts of rice-bran oil refining include waxes, lecithin, soap-stock (containing high-value oryzanol), and deodoriser distillate containing sterols, tocopherols, tocotrienols and squalene. The characteristics and physical properties of purified rice wax are similar to camauba wax (Sayre and Saunders...

As its common name indicates, palmitie aeid is a major constituent of the oil from palm trees. However, palmitic acid does not only oeeur in the products of palm trees but occurs widely in naturally derived oils and extraets from both plant and animal sources. Plant material sources include soybean oil [1], eoeoa butter [2], palm kernel oil [3], wheat bran oil [4], pumpkin seed oil [5], to name but a few. Additionally by-produets from oil production also contain palmitic acid, for example soybean oil and palm oil deodoriser distillates [6,7]. Fish oils also contain a significant amount of palmitic acid, as shown in the review project of Gruger et al. [8],... 

Stoldt and Brunner [87] considered the phase behaviour of various deacidified palm oils and soybean oil deodoriser distillates. They foeused their study in the compounds other than the acids/triglyeerides present and showed that the other components can all be eoneentrated either in the extract or the rafimate of a SCF proeess. However, improved purity palmitic acid fractions are obtained as by-products in their proeess, showing that palmitie aeid ean also be recovered from these sources. 

Steam distillation is also a very simple and effective method for the purification or deodorisation of high-boiling organic substances (e.g. essential oils). In the food industry, fats or fatty acids are deodorised and decolourised with steam. Continuous steam distillation in a column is used for this purpose. In this operation, the heated oil is run as a thin film countercurrently to the steam this reduces the amount of steam...

Bleaching is achieved by adsorption on activated bleaching clays (sorbents of the aluminium silicate type) or in combination with other adsorbents (such as activated carbon, also known as activated charcoal) to remove oil soluble pigments (such as carotenoids and chlorophylls), residual phosphoHpids, and eventually soap residues resulting from the deacidification process. Volatile substances are removed by deodorisation via steam distillation under reduced pressure. The volatile compounds are mainly responsible for the unpleasant smeU and aftertaste of cmde oil, so this process provides organoleptically neutral, indifferent oils.
