Occupational sensitization to lactase in the dietary supplement industry
Archives of Environmental & Occupational Health, 2016Aerogen lactase exposure carries a risk for the development of allergic asthma and rhinitis; only a few occupationally affected patients have been reported.

There is an established need to deliver lactase in milk to retain activity during storage and hydrolyze lactose after ingestion. In this work, spray-dried lactase powder was encapsulated in solid-in-oil-in-water (S/O/W) emulsions to fabricate delivery ...

On the inducibility of a pancreatic lactase
Archives of Biochemistry and Biophysics, 1969Abstract Induction of synthesis and secretion of pancreatic lactase by ingestion of lactose was reported by Bayliss and Starling in 1904 and subsequently confirmed by others. Since this appears to have been the earliest report of induced mammalian protein biosynthesis, these experiments were repeated in a variety of ways.

Using active lactose to hydrolyze lactose during storage is a common process to produce lactose-hydrolyzed (LH) milk. Proteolysis induced by residual proteases in commercial lactase was studied in a system using purified β-casein or β-lactoglobulin ...

Calcium absorption from milk in lactase-deficient and lactase-sufficient adults
Digestive Diseases and Sciences, 1986To determine whether lactose influences the absorption of calcium, the uptake of calcium from lactose-hydrolyzed milk and from unhydrolyzed milk was measured in 20 adults: 10 were lactase-deficient and 10 were lactase-sufficient as defined by breath hydrogen test, plasma glucose determination after oral lactose dose, and presence or absence of symptoms

Purification of calf intestinal lactase
Biochimica et Biophysica Acta, 1952Abstract A procedure for preparing a purified lactase from calf intestine is described. The enzyme preparation obtained has about 100 times the activity of the original extract, an optimum pH range of 5.5–6.0, and is maximally stable in solution at pH 5.0. Glucose inhibits hydrolytic action of the enzyme but galactose has no effect.

Lactose nutrition in lactase nonpersisters.
Asia Pacific Journal of Clinical Nutrition, 2015Lactose handling by the human gut by most people, beyond being breast-fed, has been considered a disorder rather than physiological. A non-human mammalian milk source is novel for the majority. During the first 6 months of life, when neonates and infants

Lactase Deficiency: Prevalence in Osteoporosis
Annals of Internal Medicine, 1978We determined the prevalence of lactase deficiency by analysis of respiratory hydrogen (H2) in 30 women with idiopathic postmenopausal osteoporosis and in 31 female control subjects without evidence of metabolic bone disease. Eight subjects with osteoporosis had breath H2 excretion greater than 0.20 ml/minute at 2 h after receiving 50 g of lactose and ...

Lactases and their Applications
1981Lactose or milk sugar is a disaccharide found in the milk of mammals. Lactose itself is not sweet, it has a low solubility and it cannot be absorbed directly from the intestine. Lactase splits lactose into glucose and galactose, which have a sweetening power of about 0–8 relative to sucrose; they are 3–4 times more soluble than lactose and are easily ...
