“…In this study, we focused on polycarbosilanes that had lactose‐derived moieties in the polymer side chains (PSB‐Lac). Lactose is a disaccharide composed of glucose and galactose subunits, and it is contained 2~8 wt% in milk . Because several million tons are produced annually as a byproduct of the dairy industry, one can access lactose in a large scale at a low cost.…”

A polycarbosilane having lactose‐derived structures was synthesized, and its thermal property, cytotoxicity, chemical crosslinking, and protein adsorption properties were investigated. The polycarbosilane (PSB‐Lac) was prepared by a thiol‐ene reaction between precursor poly(1‐(3‐butenyl)‐1‐methylsilacyclubane) (PSB) and heptaacetyl lactose that carried a thiol group at the anomeric position, and the successive deprotection of the acetyl groups. The lactose introduction efficiency determined by 1H NMR measurement was 75%. TGA and DSC revealed that the polymer had a 5 wt% decomposition temperature of 260 °C and glass transition temperature (Tg) of 84 °C, which indicated that PSB‐Lac was a thermally stable polymer. PSB‐Lac had no significant cytotoxicity, which was evaluated by human liver cancer cell line HepG2 cultivation on the polystyrene dishes coated with the polymer. Urethane‐crosslinked PSB‐Lac films were prepared by casting solutions of PSB‐Lac and hexamethylene diisocyanate and heating at 120 °C after evaporation of the solvent. The crosslinked PSB‐Lac showed higher adsorption of bovine serum albumin than the similarly crosslinked polycarbosilane that had a glucose structure (PSB‐Glc). © 2019 Wiley Periodicals, Inc. J.

“…The first investigated binder component, lactose (IUPAC: β-D-galacto-hexopyranosyl-(1!4)-D-gluco-hexopyranose, sum formula: C 12 H 22 O 11 ), is a common carbohydrate that is colloquially known as milk sugar. 24 The Haworth projection of α-lactose is presented in Figure S1. Chemically speaking, lactose is an aliphatic compound sporting eight OH groups, an acetal group ((R-O-)C(-O-R)(-O-R), wherein R represents an arbitrary organic rest), and a hemiacetal group ((R-O-)C(-O-R)(-OH)).…”

Lactose and tannin are eco‐friendly alternatives to commonly used binders for carbon‐bonded alumina filters that are applied in steel melt filtration. The investigation of binder pyrolysis is a contribution to understand the production process of these filters. In this work, lactose and the tannins gallic acid, ellagic acid, and tannic acid were investigated by Raman spectroscopy. The tannins were measured in situ in an argon‐filled heating chamber. The transformation of the tannin molecules to a system of amorphous disordered carbon could be observed in the Raman spectra. In addition, the condensed pyrolysis products of the tannins were measured and identified. The Raman spectra were supported by peak positions calculated with density functional theory.

“…The next steps for the production of lactose are the following: concentration, usually by evaporation; crystallization, which can be spontaneous or by seeding with a small amount of α-lactose monohydrate (which is the most commonly commercially produced); separation of crystals from mother liquor, which is done by centrifugation; washing; drying; and, finally, classification. This crude lactose can be refined to produce pharmaceutical-grade lactose (Kastens and Baldauski, 1952;Westhoff et al, 2000). A lot of the lactose produced in the United States is exported in the form of dried permeate to other countries for animal feed purposes.…”

Lactose has different uses in the dairy, food, and pharmaceutical industries. Being aware of the different forms of lactose and their concentrations can be very helpful in managing dairy product quality, properties, and manufacturing efficiency. Correct measurement and reporting of lactose concentration in milk and other dairy products will be of increased importance in the future as more value-added uses of lactose are developed and as milk lactose data are used in farm management decision making. Lactose should be reported as anhydrous lactose because lactose data will be used to make increasingly important decisions in dairy processing, dairy product labeling, and milk production in the future. Lactose also plays an important role in milk synthesis within a cow. Milk production factors and dairy cattle breed selection influence the amount of high value fat and protein produced per unit of lactose. If the off-farm value of lactose remains low, more attention may be focused on using ultrafiltration to process milk and leave 50 to 60% of the lactose and water from milk at the farm to recover the energy value of the lactose as feed and reduce the hauling cost of the high value components of milk to a dairy product manufacturing factory. Many methods exist to determine lactose concentration, but the most important methods are enzymatic assays, HPLC, and mid-infrared analysis. New, value-added uses for lactose need to be developed. Consistent and accurate methods of lactose measurement and consistent expression of lactose results will support this development process. Starting in January 2017, the USDA Federal Milk Market Laboratories began reporting lactose content of milk as anhydrous lactose and discontinued the reporting of lactose by difference.
