Margarines oil blending

Compounding the margarine oil blend at the refinery final deodorization shipping the melted blend to the margarine plant and storage under a nitrogen blanket. 

Consumer Margarine Oil Formulations. Consumer margarines are formulated by blending two or more basestocks with different degrees of hardness. This permits the margarines to be spreadable directly out of the refrigerator and to maintain a solid consistency at room temperature. Hydrogenated cottonseed oil was a... 

The possible application of enzyme-assisted reactions for production of lower value nonspecialty lipids such as margarine hardstocks and cooking oils has been reported (50). When nonspecific lipases, such as those from Candida cylindraceae and C. antarctica, are used as biocatalysts for interesterification of oil blends, the TAG... 

As many margarine plants in the United States are located at considerable distance from their suppliers, truck or rail shipment is required. Loading temperatures and whether the oil must be nitrogen blanketed are specihed. For truck deliveries, the temperature on arrival often is specihed to ensure that the oil is completely liquid. In order to minimize the possibilities for oil degradation, it is optimal to process and deodorize the oil blend at the margarine production location. 

Soft Margarine. In order to fill the container properly, soft margarine must be quite fluid. Usually there are no quiescent tubes. A large blender is used for work softening so that the product does not become brittle as a result of excess crystallization in the bowl (Figure 4). For a low-solids oil blend the blender can be placed between the A units or replaced with an extrusion valve to avoid... 

The first perspective concerns bleaching options for oil blends such as those supplied by refiners to margarine plants and shortening packing facilities. Such blends are made up of several components such as one or more hardstocks and one or more liquid oils that have to meet color and sensory specifications. This means that these blends will have been deodorized and previously undergone an adsorption treatment. Dijkstra pointed out the following possible ways that exist to arrive at a fully refined oil blend ... 

Generally, the recommended flow rate for palm-oil-based industrial margarines is approximately 60% of the nominal capacity of a scraped-surface heat exchanger process line for industrial margarine (27) for example, a scraped-surface heat exchanger with a nominal capacity of 3000 kg/h for oil blends based on oils such as soybean oil or cottonseed oil will, for oil blends based on pahn oil, have a capacity of approximately 1800 kg/h. 

With today s health conscious discussions in the media and the use of transisomeric fatty acid content in margarines as a marketing parameter, the interesterification of oil blends may possibly gain some momentum in the future. 

It is difficult to determine the latent crystallization heat in oil blends for margarine production due to their complexity. 

Choice of type of SSHE, shaft and blade design, flow rate and required product retention time, oil blend formulation, as well as process temperature profile along with several other factors have a significant influence on the hnal quality of any puff pastry margarine (51, 105).
