Milk, powdered

The ingredient business is important in the organic industry, as it provides milk, butters, cheeses and dried ingredients for the production of other organic products such as ready-to-eat entrees, cookies, confectionery, etc., as well as for use in further dairy production such as yogurt or ice cream. 

The organic dairy sector has modelled itself on the conventional dairy world in that it is represented in every feature of the dairy supermarket. From yogurt to milk, from cottage cheese to cheddar, from butter to powdered milk, there is an organic counterpart to each conventional product. The farms range in size from 9 cows to 1000, from family owned and operated to corporate enterprises. 

However, with all these similarities, the difference in organic is the treatment of the soil, the air, the water, the animals and ultimately the value of the food produced for the people. In America consumers are becoming more conscious of their need to demand food which supports rural America and is healthy for the farm worker, the store handler and the ultimately the family which it nourishes.

Direct and indirect competition formats, illustrated in Figure 1, are widely used for both qualitative and quantitative immunoassays. Direct competition immunoassays employ wells, tubes, beads, or membranes (supports) on to which antibodies have been coated and in which proteins such as bovine semm albumin, fish gelatin, or powdered milk have blocked nonspecific binding sites. Solutions containing analyte (test solution) and an analyte-enzyme conjugate are added, and the analyte and antibody are allowed to compete for the antibody binding sites. The system is washed, and enzyme substrates that are converted to a chromophore or fluorophore by the enzyme-tracer complex are added. Subsequent color or fluorescence development is inversely proportionate to the analyte concentration in the test solution. For this assay format, the proper orientation of the coated antibody is important, and anti-host IgG or protein A or protein G has been utilized to orient the antibody. Immunoassays developed for commercial purposes generally employ direct competition formats because of their simplicity and short assay times. The price for simplicity and short assay time is more complex development needed for a satisfactory incorporation of the label into the antibody or analyte without loss of sensitivity. 

Lopez-Avila and Benedicto combined SEE with ELISA to determine sulfamethazine in powdered milk. Various conditions were tested in order to achieve quantitative extraction of sulfamethazine. Variations in extraction pressure, temperature, extraction period, and the presence of organic modifier resulted in extraction efficiencies of 0-92%. Once optimal extraction conditions had been developed, a commercially available ELISA was utilized to determine sulfamethazine concentrations. The LOD was 2.5 pgkg and satisfactory recoveries were obtained at levels from 5 to 15 pgkg-i.

A dust or vapor explosion sometimes happens accidentally in industries, causing great damage. Several readily available materials are explosive when mixed with air in the form of a dust or vapor, so such explosions can be induced as a sabotage technique. Among suitable materials are flour, cornstarch, powdered milk, cocoa, very fine aluminum or magnesium powder, gasoline, and fuel oil. 

MATERIALS Explosive, thermate, blasting cap, and secondary material flour, cornstarch, powdered milk, cocoa, gasoline or other volatile fuel.

The two main assumptions underlying the derivation of Eq. (5) are (1) thermodynamic equilibrium and (2) conditions of constant temperature and pressure. These assumptions, especially assumption number 1, however, are often violated in food systems. Most foods are nonequilibrium systems. The complex nature of food systems (i.e., multicomponent and multiphase) lends itself readily to conditions of nonequilibrium. Many food systems, such as baked products, are not in equilibrium because they experience various physical, chemical, and microbiological changes over time. Other food products, such as butter (a water-in-oil emulsion) and mayonnaise (an oil-in-water emulsion), are produced as nonequilibrium systems, stabilized by the use of emulsifying agents. Some food products violate the assumption of equilibrium because they exhibit hysteresis (the final c/w value is dependent on the path taken, e.g., desorption or adsorption) or delayed crystallization (i.e., lactose crystallization in ice cream and powdered milk). In the case of hysteresis, the final c/w value should be independent of the path taken and should only be dependent on temperature, pressure, and composition (i.e.,... 

The certified reference material (CRM 450), used for the validation of the method, is real contaminated powdered milk with a certified content in PCB-52, PCB-101, PCB-118, PCB-156, and PCB-180. This material contains approximately 3.9% water and 25% fat. It is used after reconstituting and was supplied by the EC Community Bureau of Reference (BCR).

The concentrations of fluoride in ready-to-feed formulas in the United States and Canada range from 0.1 to 0.3 mg/L while the fluoride concentrations of powdered or liquid-concentrate infant formulas depend mainly on the concentration of fluoride in the water used to reconstitute the product [8], A study on the concentration of fluoride in infant formula reconstituted with water in Australia revealed concentrations from 0.031 to 0.532 mg/L of fluoride for formulas reconstituted with water not containing fluoride, 0.131 to 0.632 mg/L of fluoride for formulas reconstituted with water containing 0.1 mg/L of fluoride and 1.031 to 1.532 mg/L if formulas were reconstituted with water containing 1.1 mg/L of fluoride [124]. Concentrations of fluoride in 10 samples of powdered milk formulas in Brazil ranged from 0.01 to 0.75 mg/L for those prepared with deionized water, from 0.02 to 1.37 mg/L for those prepared with bottled mineral water containing...

Applications of the Karl Fischer method are numerous food stuffs (butter, margarine, powdered milk, sugar, cheese, processed meats, etc.), solvents, paper, gas, petroleum, etc. Before the determination can be made, solid components that are not soluble must either be ground into powders, extracted with anhydrous solvents, eliminated as azeotropes or heated to eliminate water. Problems are encountered with very acidic or basic media that denature reactants and transform ketones and aldehydes into acetals that interfere with the titration. Special reagents must be used in these instances. 

In order to measure the quantity of water in powdered milk by the method of Karl Fischer method, the reactant is first standardised as follows ... 

Then, 205 mg of oxalic acid dihydrate is introduced. A further aliquot (13 mol) of KF reagent must next be added to attain a new equivalence point. Finally 10 ml of the same solvent containing 1.05 g of dissolved powdered milk is introduced. Again KF reagent (12 ml) is added to find a final equivalence point. 

Measurement 10ml of this solvent neutralises 10 x 3/15 = 2ml of reactant, thus 1.05g of powdered milk will react with 12 — 2= 10 ml of this same reagent. There are therefore 4.51 x 10 = 45.1 mg of water in the sample, which is a concentration of...

SPRAY DRYING. A process used in the production of numerous chemical and food products. It is widely used in connection with the production of powdered milk and instant coffee preparations. The spray drying is unique among dryers in that it dries a finely divided droplet by direct contact with (lie drying medium (usually air) in an extremely short retention time (3 to 30 seconds). This short contact time results in minimum heat degradation of the dried product, a feature that led to the popularity of the spray dryer in the food and dairy industries during its early development. In the case of coffee extract, water in the feed will range from 50 to 70%.

The causes of human copper deficiency include (1) low intake - malnutrition, total parenteral nutrition (TPN) (2) high loss - cystic fibrosis, nephrotic syndromes and (3) genetic factors — Menkes disease. Copper deficiency may also be associated with chronic malabsorption, a situation which is made much worse in cases of gastric and bowel resection. Several special diets, including powdered milk, liquid protein and standard hospital diets are a means of inducing copper deficiency. The amount of copper in US food has decreased steadily since 1942, and may be related to the rising incidence of coronary artery disease. A copper deficiency may also occur as the result of the use of chelators for other purposes for example, diethyl dithiocarbamate is an in vivo metabolite of ANTABUSE (disulfiram). 

Heroin is usually cut with baking soda, powdered milk, baby powder, sugar, starch, or quinine, but has also known to be cut with lidocaine, curry powder, strychi-nine, and even laundry detergent. Law enforcement officials in New York report the existence of heroin cut with a rat poison from Santa Domingo called Tres Pasos (meaning three steps ). Three is the number of steps the mice take before dying after exposure to the poison.
