摘要:
The invention relates to the technical field of food processing, in particular to a Pickering particle dry powder and a preparation method thereof. The preparation method comprises the following steps: (1) stirring peanut protein isolate and water as raw materials to obtain peanut protein isolate dispersion; (2) subjecting the peanut protein isolate dispersion to ultrasonic treatment, and then subjecting the resultant to cross-linking reaction with transglutaminase to obtain a monolithic gel; (3) shearing and homogenizing the monolithic gel to obtain a microgel particle dispersion; (4) spray drying the microgel particle dispersion to obtain the Pickering particle dry powder. The Pickering particle dry powder prepared by the ultrasonic-assisted enzyme method according to the present invention is still in nanometer level after rehydration, which is beneficial to preparing Pickering emulsion with strong stability. The preparation method provided by the invention has the advantages of simple operation and low cost, which is beneficial to actual production in the food industry.

The invention relates to self-assembling microparticles comprising a solid matrix and probiotic bacteria, wherein the solid matrix comprises soybean protein and a divalent or trivalent metal, and wherein the probiotic bacteria are distributed throughout the solid matrix; said matrix protects said probiotic bacteria during processing, storage, as well as during transit through the gastrointestinal tract, thus prolonging their lifetime and facilitating release into the intestine and improving their probiotic effect. The present invention also relates to the method for obtaining the self-assembling microparticles and to the products and compositions incorporating them.

A method of controlling the spray droplet size of a spray nozzle apparatus, in particular for the manufacturing of food powders, delivered to the spray nozzle comprises the following steps: a) providing a paste of a product to be sprayed by a spray nozzle; b) continuously determining the shear viscosity (η) of the product paste delivered to the spray nozzle; c) determining the mass flow rate (Qm) of the product paste delivered to the spray nozzle; d) determining the static pressure (P) of the product paste delivered to the spray nozzle; e) determining the density (p) of the product paste delivered to the spray nozzle; f) delivering the data obtained in steps b) to e) to a control device comprising a computer and a memory; g) calculating control data for adjusting the spray nozzle on the basis of the data obtained in steps b) to e) and on nozzle geometry parameters stored in the memory; h) sending the control data as control signals to a control means of the spray nozzle and adjusting the spray nozzle accordingly.
摘要:
This invention corresponds to the field of Chemistry, and specifically, to treatment of foods stuffs to stabilize bio-components, such as those polyphenols with a recognized capability to link reactive species of oxygen associated to development of chronic and degenerative diseases, such as cancer, which bio-components have been considered as antioxidant polyphenols. In particular, the invention proposes a specific solution of an obtained stable product which involves electro-spray drying or spray drying for stable conservation of yellow pitahaya polyphenol biocomponents, as a proposed solution of unique temperature, times and stages, which in addition has its own Syringe for the electro spraying system.
摘要:
The invention concerns a lightened fat which is obtained by replacing some of the initial vegetable and/or animal fat with a non-animal raw material, a microalgal flour, and the uses thereof as novel product in the fields of breadmaking and/or patisserie and/or viennoiserie.
摘要:
The present invention relates to microalgal flour granules, their use in food products and a process for preparing the microalgal flour granules. The microalgal flour granules have specific particle size distribution , flow capability and wettability properties.
摘要:
The invention relates to a novel cooking product characterised in that at least one of the three ingredients selected from among eggs or egg products, milk or milk derivatives and fatty substances of animal and/or plant origin is completely or partially replaced with microalgal flour. The novel cooking product can in some cases be consumed by allergic and/or vegetarian persons. The invention also relates to the method for the production of said cooking product.
