A method used for concentration of fluid milk by renewable energy (RE). RE used in the present invention is sole solar energy (SE) at room temperature (25° C.-27° C.). A device of two glass Petri dishes of same size is arranged as upper and lower plates. A volume of 60 ml of pasteurized bovine or camel milk is put in the upper plate and 60 ml of tap water in the lower plate. The device is placed on the bench beside window to be exposed to sunlight, but not to direct sunrays, at room temperature. After about 30 mins water droplets started to appear on the lower face of the upper plate and increased in size with time. With continuous collection of water droplets for 24 hours, 50% of water is removed i.e. giving 50% concentration of milk; after 48 hours the concentration is 16.67%.

A process for making a shelf-stable food, not requiring preservatives or refrigeration and in a form that is convenient for use as a snack food. A block of tofu or wheat gluten is first frozen so as to cause the formation of ice crystals that form cavities within the block. The frozen block is then thawed, cut into smaller pieces and drained of excess water. The thawed pieces are dried in a microwave-vacuum dehydrator to produce a crunchy food product.

The present invention relates to a method (200) for producing a heat-treated concentrated dairy product (cdp). The method (200) comprising the steps of passing (210) the dairy product (dp) under a pre-determined pressure through a reverse osmosis, RO, filter (110) at a first temperature, the pre-determined pressure being sufficient to allow reverse osmosis, thereby concentrating the dairy product (dp). Preheating (230) the concentrated dairy product (dp) at a second temperature for a second period of time to stabilize the concentrated dairy product (dp). Homogenizing (240) the stabilized concentrated dairy product (dp) to reduce a size of particles in the stabilized concentrated dairy product (dp). Heating (250) the stabilized concentrated dairy product (dp) at a third temperature for a third period of time to reduce microorganisms in the stabilized concentrated dairy product (dp), thereby forming the heat-treated concentrated dairy product (cdp).

Disclosed are methods for preparing aseptic dairy compositions having at least 35 wt. % solids, and often from 40 to 50 wt. % solids, by subjecting a dairy product to forward osmosis following by a heat treatment step. The heat treatment step can include UHT sterilization via direct steam injection or direct steam infusion. Subsequently, the aseptic dairy composition can be dried to form a dairy powder composition.

Disclosed is a method for making yogurt products of viscosities from about 50 centipoise to about 200,000 centipoise, the yogurt products having a total protein content of at least about 12 percent, the whey protein in the product being primarily in the undenatured state (at least about 75% undenatured). Also disclosed are products made by the method, such as yogurt drinks comprising at least about 12 percent total protein, wherein at least about 75% of the whey protein is in the undenatured state.

The disclosure relates to a method of making a beverage comprising a milk protein concentrate (MPC), a beverage comprising an MPC, an MPC or use of a MPC. More particularly, this disclosure relates to treatment of an MPC to allow for heat homogenisation of a beverage containing the MPC, while reducing occurrence of malodour and/or egg-type or sulphur-type smell and/or taste.

A composition of matter wherein the composition comprises a siliceous substrate having silanols on the surface and a polymer selected from the group consisting essentially of a water soluble polymer, a water soluble copolymer, an alcohol soluble polymer, an alcohol soluble copolymer, and combinations of such polymers, wherein the polymer is chemically bonded to the siliceous substrate by a silane linking material having the general formula
O.sub.3/2SiQY
that is derived from an alkoxy-functional silane having the general formula
(RO).sub.3SiQX
and processes for preparing the crosslinked polymer that is chemically bonded to the surface of the siliceous substrate.
