By the end of this year, after 9 years of operation, UNICEF will have shipped, or allocated for shipment, a total of about 700,000,000 lb. of dried skim milk. In addition, it will have allocated the equivalent of over E3,5oo,ooo for milk-conservation projects. The purpose of this paper is to present some points of interest from a nutritional point of view on how and why this was done, together ...

Freeze-drying is a common preservation technology in the pharmaceutical industry. Various studies have investigated the effect of different cryoprotectants on probiotics during freeze-drying. However, information on the effect of cryoprotectants on the stability of some Lactobacillus strains during freeze-drying seems scarce. Therefore, the aim of the present study was to establish production m...

Gravimetric fat data were obtained for a wide range of dairy products with fat contents ranging from 0.5 to 83% using pressurized solvent extraction at elevated temperatures and pressure (80-120 degrees C; 10.3 MPa). Extraction performance was sensitive to solvent composition, temperature, and sample matrix. By optimizing solvent mixtures, sample-solvent contact times of 8-10 min were sufficien...

Skim milk of approximately 3% total protein was ultrafiltered to 16.2% protein and 4.1 % lactose, and then diafiltered to reduce lactose to 2.1% and 0.9%. Total protein con ten t was maintained at approximately 17%. A ponion of the sk im milk was condensed in a rising film evaporator to 14.7% protein and 15.7 % lactose . All concentrates were spray dried at 120 to 125 °C inlet air temperature a...

A standardized descriptive language for skim milk powder and dried dairy ingredients was developed. The lexicon was initially identified from a large sample set of dried dairy ingredients (138). A highly trained descriptive panel (n = 14) refined terms and identified references. Dried dairy ingredients (36) were then evaluated using the developed language. Twenty-one descriptors were identified...

This work aimed to establish an integrated approach investigate the total phenolic content and antioxidant activities of dried skim camel cow milk their fractions. The fractions were obtained by acid or enzymatic coagulation followed spray drying (inlet temperature/outlet temperature: 125 ± 2 °C/90 °C) freeze (−50 °C, 0.05 mbar) coupled not gamma irradiation (at 5, 11, 22 kGy). results showed t...
