A spray drying process and apparatus for drying a spray dryable liquid composition to a spray dried powder is described, in which the spray dryable liquid composition contains no carrier. The spray dryable liquid composition is processed at a solids concentration not exceeding 80% by weight, based on total weight of the spray dryable liquid composition, being atomized to generate an atomized spray of liquid particles of the spray dryable liquid composition into a spray drying chamber, in which the atomized spray is contacted with a stream of drying fluid flowed at temperature not exceeding 100° C. into the spray drying chamber, to form the spray dried powder.

A method for unlocking bioactive proteins that can then be used to activate natural remedies. The method includes starting with Silica salt and water mixture. Then a base of whey protein concentrate is added to the mixture. The pH of the whey protein mixture is raised using a base. The pH is held at a level above 11 for at least two hours. After at least two hours an acid is then added to the mixture to bring the pH of the mixture below 3 pH. This will stop the activation process. After the unattached proteins are removed the protein mixture is then brought back to a normal pH level, around 4 pH.

The invention concerns a process for the treatment of a sweet whey material containing cGMP (caseinoGlycoMacroPeptide), said process comprising the following steps: Decationising the sweet whey material so as to obtain sweet whey material having a pH value of 1 to 4.5; Treating said sweet whey in a fluidized bed reactor comprising a specific volume of an anionic resin, at a temperature between 10 and 18 C., wherein said sweet whey contacts said resin for a sufficient amount of time so that the resin absorbs between 52% and 58% of the cGMP present in the sweet whey; andRecovering a protein material. Advantageously, the protein material is suitable for hypoallergenic infant formulae.

A method of and apparatus (18) are described for assessing fat in whey in the making of a dairy product in accordance with a dairy product recipe. The method comprises the steps of: a. using one or more optical sensors (61, 62, 63, 64) to sense at least one stream (22, 24, 27, 29) of whey separated from curd in dairy product making apparatus (18) and generate one or more signals indicative of the degree of occlusion of the stream (22, 24, 27, 29) of whey; b. converting or processing one or more said signals as a measure of the specific mass of fat lost from curd in a dairy product making plant (18) in the stream of whey; c. assessing whether the value of specific mass of fat lost obtained in Step b lies within or outside a predetermined fat loss range; and d. if the said value of specific mass of fat lost is outside the predetermined range, adjusting the recipe so that the value of specific mass of fat lost lies within the predetermined range.

An aqueous modified acid composition for industrial activities, said composition comprising: an alkanolamine and strong acid in a molar ratio of not less than 1:15, preferably not less than 1:10; it can also further comprise a metal iodide or iodate. Said composition demonstrates advantages over known conventional acids and modified acids.

A method for preparing a modified whey protein concentrate (WPC) or whey protein isolate (WPI) is described. It involves (a) providing an aqueous WPC or WPI solution having a protein concentration of 15-50% (w/v), at a pH of 4.7-8.5; (b) heat treating the solution to more than 50 DEG C, for a time that allows protein denaturation to occur the heat treating comprising heating the solution while under conditions of turbulent flow. At the end of the heat treatment, the heat treated material may be promptly transferred to a drier or to be mixed with other ingredients. The heat-treated WPC or WPI is not subjected to a mechanical shear process prior to the transfer other than where liquid is converted into droplets to facilitate drying. The modified WPC is useful in the manufacture of food and drinks where a high protein content is desired without undesirable changes in texture.
