Effect of Lactose Source, Lactose Level, and Type of Emulsifying Salts on the Properties of a Processed Cheese Product
… nonfat dry milk, whey protein concentrate 34 and lactose powders in processed cheeses or cheese analogs found that increasing the percentage of lactose was associated with an increase in browning and crystallization. There has been little work done of the effects of lactose in processed cheese …

GROWTH AND MECHANICAL DEFORMATION OF ALPHA-LACTOSE MONOCRYSTALS
… properties and deformation behaviour of alpha-lactose crystals. Chapter 2 conducts a detailed investigation into the crystallisation and growth kinetics of alpha-lactose monohydrate crystals by an agar-gel suspension technique. A large number of morphologically well-formed alpha-lactose …

Lactose Polymerization to Polylactose: Furthering Our Understanding for Commercialization
Polylactose, soluble fiber that has been manufactured from a blend of lactose, glucose and citric acid using reactive extrusion, has been developed in our lab. A benchtop method for polylactose production was developed that allowed for the evaluation of formulation impact on the polymerization …

Whey-Caseinate Blends and Lactose Hydrolysis in Yogurt Manufacture
… nutritious whey products, such as partially delactosed or demineralized whey powders and whey protein concentrates (WPC) with the proteins in an undenatured form, are available to the dairy processor. Depending upon the processing methods, the whey protein products possess a wide range of …

Hydrolyzed-Lactose Whey and Nonfat Dry Milk in Ice Cream
… A commercial lactase was used to hydrolyze lactose to over 90% conversion and the lactase was inactivated after hydrolysis. The extent of lactose hydrolysis in the mix was adjusted to 50% or 75% by blending non-hydrolyzed nonfat dry milk and whey solids with hydrolyzed preparations. Extra …

Use of Dry Whey and Lactose Hydrolysis in Yogurt Bases
… β-D-galactoside galactohydrolase) to hydrolyze lactose, the major carbohydrate of milk, into its constituent monosaccharides glucose and galactose prior to product manufacture has received considerable attention during the past decade. Applications for the food industry are readily apparent; one …

Determination of Lactose by Reversed-Phase High Performance Liquid Chromatography.
<p>Lactose is the common disaccharide found in dairy products. It can, however, be a source of discomfort for those whom are lactose intolerant. Therefore, it is necessary to accurately, reliably, and efficiently determine the lactose content of foods. The goal of this research was to develop a …

Some nutritional considerations of lactose malabsorption in Mexican American children
Recent reports have appeared on the occurrence of lactose intolerance and low intestinal lactase activity in otherwise apparently healthy populations. In these individuals, administration of an oral lactose load fails to produce a significant increase in blood glucose concentrations and may be …

Factors in Ultrafiltration and Thermal Concentration of Whey Affecting Commercial Lactose Crystallization
<p>The source for lactose production in the United States is almost exclusively sweet (low acid) whey which is the byproduct of cheese manufacture. Its extraction from the whey is motivated largely by pressures to utilize whey components to advantage. The ability to recover lactose efficiently is …

Lactose Operon Expression and Plasmid Rearrangement in Rhodopseudomonas Sphaeroides (Gram Negative Bacteria)
… bacterium were recovered that were able to use lactose as the sole carbon source and which had elevated (beta)-galactosidase expression. The mutation allowing growth on lactose was determined to be on the R. sphaeroides endogenote and not on Tn951 DNA.

Isolation and lactose metabolism of Streptococcus lactis variety tardus from southwestern Virginia
… silicic acid column chromatography of the spent lactose-phosphate-yeast extract media. Two cultures of S. lactis var. tardus were isolated from parent§_. lactis cultures that were being transferred in litmus milk rehydrated with distilled water during a four- to ten-month period. The cellular …

The Effect of Probiotics, Prebiotics, and Synbiotics on Indicators of Lactose Intolerance: A Systematic Review
<p>Lactose intolerance disproportionately affects racial minority groups in the United States, increasing the incidence of calcium deficiency and low bone mineral density in these populations. The nutritional quality of lactose-containing food products incentivizes the investigation of long-term …

The Effect of Crystalline and Amorphous Lactose on Mechanical Properties of Roller Compaction Ribbons and Tablets
Lactose is a widely used excipient in the pharmaceutical industry. It exists as anhydrous, alpha- and beta- monohydrate forms, which can be either crystalline or amorphous. Commercially available lactose comes in various grades differentiated by physical forms as well as modifications such as …

Breath hydrogen studies of lactose malabsorption in children resident in New Zealand, Cook Islands and Western Samoa
Lactose malabsorption (LM) in children was diagnosed by an elevated breath hydrogen (BH) level following a 10g lactose load. A portable gas chromatograph and a semiconductor detector, designed and constructed for use in the Pacific Islands is described. Following verification on known malabsorber …
