Abstract

Vynález sa týká spósobu výroby mlieka sušeného s obsahom tuku. Podstatou vynálezu je prídavok monoacylglyceridov, alebo zmesi mono a diacylglyceridov do mlieka po jeho predchádzajúcom tepelnom ošetření a úpravě tukovosti, následná homogenizácia a sprayové sušenie s aglomerizáciou častíc, alebo bez nej. Dosahujú sa lepšie rekonstitučné vlastnosti mlieka a spomalenie hydrolytických a oxidačných zmien mliečneho tuku a tým predlženie doby použitelnosti sušeného mlieka.The invention relates to a method for producing powdered milk with a fat content. The essence of the invention is the addition of monoacylglycerides, or a mixture of mono and diacylglycerides to milk after its previous heat treatment and fat content adjustment, subsequent homogenization and spray drying with or without particle agglomeration. Better reconstitution properties of milk are achieved and the slowing down of hydrolytic and oxidative changes of milk fat and thus the extension of the shelf life of powdered milk.

Description

(54) Sposob výroby sušeného mlieka(54) Method of production of milk powder

Vynález sa týká spósobu výroby mlieka sušeného s obsahom tuku. Podstatou vynálezu je prídavok monoacylglyceridov, alebo zmesi mono a diacylglyceridov do mlieka po jeho predchádzajúcom tepelnom ošetření a úpravě tukovosti, následná homogenizácia a sprayové sušenie s aglomerizáciou častíc, alebo bez nej. Dosahujú sa lepšie rekonstitučné vlastnosti mlieka a spomalenie hydrolytických a oxidačných zmien mliečneho tuku a tým predlženie doby použitelnosti sušeného mlieka.The invention relates to a process for the production of fat-dried milk. The present invention is directed to the addition of monoacylglycerides, or a mixture of mono and diacylglycerides, to milk after prior heat treatment and fat control, followed by homogenization and spray drying with or without agglomeration of the particles. Better reconstitution properties of the milk are achieved and the hydrolytic and oxidative changes of the milk fat are slowed down and thus the shelf life of the milk powder is prolonged.

Vynález sa týká spósobu výroby mlieka obsahuj úceho tuk.The invention relates to a process for the production of fat-containing milk.

Pri doterajšom bežnom spósobe výroby mlieko po predchádzajúcej úpravě tukovosti a tepelnom ošetření sa zahustí na odparkách na sušinu 35—45 g v 100 g roztoku a následné suší na sprayových sušiarniach. Finálny výrobok má poměrně nízku mernú hmotnost, dispergovatelnosť a rozpustnosť. Mliečny tuk obalujúci částice sušeného mlieka vzhladom na svoj hydrofóbny charakter negativné ovplyvňuje zmáčavosť mliečneho prášku. Okrem toho, doba použitelnosti doterajším spósobom vyrobeného sušeného mlieka vzhladom na lahkú oxidovatelnosť mliečneho tuku nachádzaj úceho sa na povrchu častíc sušeného mlieka je poměrně nízká.In the current conventional production process, the milk, after pretreatment of the fat and heat treatment, is concentrated on a dry residue of 35-45 g in 100 g of solution and subsequently dried in spray dryers. The final product has a relatively low specific gravity, dispersibility and solubility. Milk fat envelops the milk powder particles due to its hydrophobic character negatively affects the wettability of the milk powder. In addition, the shelf life of the milk powder produced by the prior art due to the low oxidisability of the milk fat found on the surface of the milk powder particles is relatively low.

Nedostatky doterajšieho spósobu výroby odstraňuje vynález, ktorého podstata je v tom, že mlieko po predchádzajúcej tepelnej úpravě, úpravě tukovosti a přídavku monoacylglyceridov, alebo zmesi mono a diacylglyceridov mastných kyselin s počtom uhlíkov 14— 20 v róznom pomere, sa homogenizuje a suší sprayovým spósobom. Pri spósobe výroby podlá vynálezu sa dosahuje vyššia měrnáThe drawbacks of the prior art process are eliminated by the invention, wherein the milk is homogenized and spray dried after prior heat treatment, fat control and the addition of monoacylglycerides, or a mixture of mono and diacylglycerides of fatty acids having a carbon number of 14-20. The production method according to the invention achieves a higher specificity

Claims (2)

PREDMET Spósob výroby sušeného mlieka s obsahom tuku vyznáčujúci sa tým, že do mlieka sa přidá po predchádzajúcom tepelnom ošetření 0,1 až 0,3 g monoacylglyceridov mastných kyselin s počtom uhlíkov 14 až 20, alebo zmesi hmotnost sušeného mlieka, vyššia dispergovatelnosť a tým aj lepšie rekonstitučné vlastnosti sušeného mlieka. Hydrolytické a oxidačně změny mliečneho tuku sa znižujú a predlžuje sa doba použitelnosti sušeného mlieka. Příklad 1 Do pasterizovaného mlieka o tukovosti 1,4 g tuku v 100 g mlieka sa přidá 0,8 g monoacylglyceridov mastných kyselin s počtom uhlíkov 14—20 na 100 g mliečneho tuku, zmes sa homogenizuje pri teplote 70 °C a tlaku 20 MPa, zahustí na sušinu 40 g v 100 g a sprayove suší. PříkladSUBJECT A method of producing fat-containing milk powder by adding 0.1 to 0.3 g of fatty acid monoacylglycerides with carbon numbers of 14 to 20, or a mixture of milk powder, higher dispersibility, and thus also the weight of milk powder, prior to heat treatment. better reconstitution properties of milk powder. Hydrolytic and oxidative changes of milk fat are reduced and the shelf life of the dried milk is prolonged. EXAMPLE 1 To a pasteurized milk with a fat content of 1.4 g of fat in 100 g of milk is added 0.8 g of monoacylglycerides of fatty acids with carbon numbers of 14-20 per 100 g of milk fat, the mixture is homogenized at 70 DEG C. and 20 MPa concentrated to dryness 40 g in 100 g and spray dried. Example 2 Do 1000 1 pasterizovaného mlieka a tukovosti 3,4 g tuku .v 100 g mlieka o teplote mlieka 74 °C sa přidá 40 kg zmesi mono a diacylglyceridov (15 kg monoacylglyceridov a 25 kg diacylglyceridov mastných kyselin s počtom uhlíkov 16). Zmes sa homogenizuje pri 19 MPa, zahustí na sušinu 45 g v 100 g mlieka a sprayove suší. mono a diacylglyceridov mastných kyselin s počtom uhlíkov 14 až 20 s róznym podielom mono a diacylglyceridov na 100 g tuku, zmes sa homogenizuje pri tlaku 8 až 40 MPa a teplote 50 až 95 °C a suší sprayovým spósobom.40 kg of a mixture of mono and diacylglycerides (15 kg of monoacylglycerides and 25 kg of diacylglycerides of fatty acids with carbon numbers 16) are added to 1000 l of pasteurized milk and fat content of 3.4 g of fat. The mixture is homogenized at 19 MPa, concentrated to a dry weight of 45 g in 100 g of milk and spray dried. mono and diacylglycerides of fatty acids having carbon numbers of 14 to 20 with a varying proportion of mono and diacylglycerides per 100 g of fat, the mixture being homogenized at a pressure of 8 to 40 MPa and a temperature of 50 to 95 ° C and spray dried.
