Separation of lactose from milk by ultrafiltration

Even though other minerals such as calcium can also pass through the membrane, they can be recovered by heating and adjusting the pH of the permeate. The separated lactose in the permeate can be used for functional foods production such as galacto-oligosaccharides which can be supplemented into the low lactose products or other dairy products. The goal of this project is to evaluate the

US5639501A Separation of minerals from whey permeate

A process for extracting milk minerals from a whey product such as whey permeate or delactosed whey permeate is disclosed. The pH of the whey product is adjusted to a pH in the range of about 7.0 to 7.6. A phosphate compound is added to the whey product in an amount such that the weight percent of phosphate added to the whey product based on dry matter solids of the whey product is in the

A study of the separation of lactose from whey

NF process was effective for mineral salts removal from whey with the aim of reusing lactose. In this way, three operation modes were studied: total recycle, concentration and continuous diafiltration. Combining the concentration and CDMs, the lactose concentration and the whey demineralization are achieved. The best operating conditions for the process (those entailing the lowest lactose loss

Potential of Membrane Separation Processes in Cheese

AbstractRecently, membrane separation techniques are extensively used in a dairy industry, which contains many valuable substances (proteins, lactose, minerals) which can be further used, e.g. in food industry or biotechnologies. This paper summarises a potential of membrane separation process, namely ultrafiltration and nanofiltration, in fractionation of whey components, such as proteins and

Modern approaches to lactose production ScienceDirect

01/01/2009· It is worth noting that calcium precipitation is the basis of the Steffen process used for the separation of lactose from whey Some minerals increase lactose solubility; for example, calcium increases lactose solubility due to the formation of lactose-CaCl 2 complexes (Herrington, 1934). Other mineral impurities may accelerate the surface deposition step of crystallisation, by lowering

Keywords: Wide pore ultrafiltration; Milk minerals; Spiral wound; Membrane separation; Milk protein concentrate Introduction In several processing industries, separation technology is widely used to separate and in some cases to purify a particular component from the rest of the mixture. The target component might be the desired product or an unwanted component, separated to increase the

Whey or raw milk demineralisation and fractionation

A process for the demineralization and fractionation of cheese whey or raw milk comprising the steps of: a) subjecting the whey or raw milk to ultrafiltration to provide a retentate fraction and a permeate fraction; b) concentrating the permeate fraction by means of nanofiltration; c) subjecting the nanofiltration retentate to ion permeation chromatography at elevated temperatures of between

Crystallization in Lactose Refining—A Review Wong -

Lactose is produced from whey permeate, which contains lactose, minerals, riboflavin, and traces of fat and protein (Table 1). To improve the separation efficiency and the yield (recovery), whey solution can be pretreated before the crystallization operation. During lactose refining, the impact of protein on lactose crystallization process is minimized because the whey protein has been

Separation of lactose from raw goat’s milk by cross-flow

In UF, water, minerals, sugars (lactose), urea, amino acids, organic acids, and vitamins pass through the membrane (Nielsen, 2000; Shakeel-Ur-Rehman, 2009), while retaining 20-40% of non-protein nitrogen compounds, up to 10% lactose and minerals, and other ions attached to proteins (calcium, magnesium, phosphate, and citrate). UF was mainly used for producing low lactose dairy products

Lactose hydrolysis and other conversions in dairy products

01/02/2012· The separation is based on the different ion- and size-exclusion effects of minerals and proteins, and probably also on the ability of lactose to form complexes with cations bound to strong cation exchange resins. This formation of lactose–cation complexes slows the flow of lactose through the resin column. According to Harju (1987b) it is important that the strong cation exchange resin is

WHEY PROCESSING | Dairy Processing Handbook

For efficient and simple separation of lactose crystals from the mother liquor, crystallization must be arranged so that the crystals exceed 0.2 mm in size – the larger the better for separation. The degree of crystallization is determined in principle by the quantity of b-lactose converted to the desired a-lactose form, and the cooling of the concentrate must therefore be carefully
