    Determination of amino acids

    The method enables fast quantitative determination in feeds, mixed fodders, and raw materials of the following amino acids: arginine, lysine, tyro sine, phenylalanine, histidine, leucine and iso -leucine (total), methionine, valine, proline, alanine, glycine, cystine, tryptophan, aspartic and glutamic acids.

    Since during the sample decomposition asparagine and glutamine are hydrolyzed to aspartic and glutamic acids, respectively, the content of these two acids represents the total content of both the acids and the amides.

    Determination of D- and L-isomers of tartaric and malic acids in wines, wine materials, and food additive

    Naturally occurred is predominantly L-form of tartaric acid whereas its D-form and the relevant racemic mixture can be artificially synthesized. Generally, artificial acidification of wine with tartaric acid is allowed by OIV, but only pure L-form must be used for this purpose. Thus the analysis of tartaric acid isomers either in food additives or directly in wine can be an important parameter in clarifying any deviations in wine production. Analysis of isomers of malic acid is also within the necessary oenological procedures stated in OIV recommendations. LUMEX INSTRUMENTS offers the present method which allows determination of L- and D-forms of tartaric and malic acids in wine, wine materials, and special food additives by capillary electrophoresis method.

    Determination of macronutrients in fertilizers

    Introduction

    The method is used for the determination of the mass fraction of all primary and secondary nutrients (macronutrients) in fertilizers by capillary electrophoresis. The method allows the determination of such macronutrients as ammonium nitrogen (ammoniacal nitrogen, NH4-N), nitrate nitrogen (NO3-N), phosphorus (P or P2O5), potassium (K or K2O) as well as sodium, magnesium, calcium, sulfur, chlorine (chloride), fluorine (fluoride).

    Determination of organic acids in feedstuff, silage, haylage, and fermentates for biogas plants

    To provide the proper conditions for silage or haylage storage in agriculture it is necessary to regularly monitor the formation of certain organic acids in it. For example, the formation of butyric acid can indicate spoiling of material. Formic or propionic acids can be artificially added to increase the nutritional quality. The same materials and some other biodegradable waists (agricultural residues, sewage sludge, etc.) are also used in biogas plants, where the fermentation process must be carefully monitored, in particular, by the determining the certain organic acids. The present method allows determination of some important organic acids like acetic, lactic, butyric, propionic, and formic in feedstuff additives, silage, haylage and in different biodegradable materials of biogas plants. Some other organic acids (oxalic, fumaric, etc.) can be also determined within this method.

    Determination of organic acids and some preservatives in wine and spirits

    The organic acids profile in wine is a highly informative parameter since it reveals important features of the whole technological process. It is also one of the most important criteria for wine authentication. In spirits like cognac, brandy or whiskey, the presence of certain organic acids can indicate the violation of distillation or maturation processes or reveal the tendency to precipitate during storage. Some organic acids (sorbic, benzoic, ascorbic) can serve as preservatives; their presence is strictly regulated. Although the presence of sorbic acid in alcoholic beverages can be natural in some cases, in other cases it can indicate severe violation of the technological process or even complete falsification.

    Quality control of milk and milk products

    In order to maintain high quality of milk products, it is necessary to monitor process quality as rapidly as possible, so that a relevant technological process could be promptly corrected. The most important quality factors of milk products are fat, protein, moisture (total solids), SNF, sugar, salt, lactose and titrated acidity. Commonly, it takes a few hours to make such type of analyses by traditional methods. The use of an InfraLUM® NIR analyzers reduces the analysis time to a couple of minutes. 

    The method is based on measuring the transmission spectrum of a sample in the near-IR spectral region and subsequent determination of the analyzed parameters/constituents using a calibration model. Transmission measurement provides highest accuracy and reproducibility of the measurements.

    Determination of whey proteins in milk samples by capillary gel electrophoresis

    One of the tests for authenticity of milk and dairy foods is the qualitative and quantitative composition of whey proteins and their ratio. Caseins dominate in cow’s milk before its processing (about 80% of total protein), whereas caseins are almost absent in the whey composition whose main components are the following:

    • β-lactoglobulins
    • α-lactalbumin
    • bovine serum albumin
    • immunoglobulins
    • lactoferrin and other minor proteins.
