Food & Beverage

Food Freshness and Flavour Monitoring Food Freshness and Flavour MonitoringLonestar is an easy to use and powerful analyzer for food production and food safety compliance.  The instrument can monitor freshness, flavours, taints or contamination in food and beverages.  It detects aromas, essences and odour chemicals with high accuracy and sensitivity.  Process monitoring with Lonestar can complement a HACCP or ISO 22000 approach to ensuring food safety and quality.
Real-time measurement of diacetyl in beer Real-time measurement of diacetyl in beerThe flavor of beer is strongly influenced by the presence of diacetyl and 2,3-pentanedione. Owlstone's Lonestar analyzer can detect and measure levels of these two vicinal diketones (VDKs) in minutes, right on the brewery floor. Offering detection down to 30ppb (parts per billion) and the ability to measure total diketones or free diacetyl, the instrument is ideal for early fermentation monitoring and finished product quality assurance.
Real Time Identification and Monitoring of Trace Contamination Real Time Identification and Monitoring of Trace ContaminationLonestar is an easy to use and powerful analyzer for accurate, real time identification and monitoring of trace contamination. Foods that contain muscle tissue (meat, poultry and fish) can form biological amines through enzymatic and bacterial actions of proteins and amino acids. For example, trimethylamine (TMA) is formed by a stepwise degradation of choline to betaine and then to TMA.
Detecting sulfites and SO2 using Lonestar Detecting sulfites and SO2 using LonestarThe Lonestar portable analyzer is able to detect whether Traditional Chinese Medicines (TCM), herbal remedies and alternative medicine products contain sulphites by detecting the presence of trace amounts of sulfur dioxide (SO2). Sulfite sensitivity affects many people making the presence of sulfites in herbal medicines a common concern for consumers.
Detecting potato rot with Lonestar Detecting potato rot with LonestarMaintaining the quality and health of stored potatoes is vital for growers, processors and consumers but each year there are consistent and substantial losses due to storage diseases. The Lonestar portable freshness monitor can detect volatile chemical signatures associated with bacterial diseases such as blackleg and potato soft-rot in real time. This allows the early detection and isolation of rotten potato stock, helping to prevent further losses.
Detecting diacetyl vapor in the workplace Detecting diacetyl vapor in the workplaceThe Owlstone Chemical Agent Monitor (OCAM) detects diacetyl, a common industrial chemical that is used in foodstuffs such as microwave popcorn as a synthetic butter flavor. Inhalation of diacetyl has been shown to cause bronchiolitis obliterans (AKA popcorn lung or popcorn workers lung), a potentially fatal disease in which the bronchioles are narrowed by scar tissue and inflammation.
Quality control of spices using Lonestar Quality control of spices using LonestarThe Lonestar gas analyzer can be used to rapidly identify and measure the volatile essential oil content of spices such as cinnamon, cumin, ginger and cloves. With sampling taking only 10s of seconds, Lonestar offers a fast alternative to time consuming distillation methods for quality control.
Rapid Screening of Plastic Bottles for dibasic esters Rapid Screening of Plastic Bottles for dibasic estersThe Lonestar portable analyzer allows rapid detection of bottle rinse cleaning solvent DBE-3 (dibasic esters) and DMS (dimethyl sebacate) in PET (polyethylene terephthalate) beverage bottles and food containers at concentrations below 50 ppb, aiding compliance with FDA food contact notifications.
Validating Clean in Place Processes Using Lonestar Validating Clean in Place Processes Using LonestarFast validation of Clean in Place (CIP) cycles by monitoring the composition of rinse water is vital to ensure adequate tank cleaning and for the optimisation of production processes in the food, beverage and pharmaceutical sectors. Lonestar delivers rapid, sensitive and accurate monitoring of rinse water helping to reduce water and cleaning product consumption.
2,4 dichlorophenol in milk detection with Lonestar 2,4 dichlorophenol in milk detection with LonestarLonestar is an easy to use and powerful analyzer for accurate, real time identification and monitoring of trace flavor contamination in milk including 2,4-dichlorophenol (DCP), 2,4-dibromophenol (DBP), biogenic amines such as triethylamine (TEA), milk adulterant benzoic acid and the milk age marker lactic acid.
Tribromoanisole Detection with Lonestar Tribromoanisole Detection with LonestarLonestar is able to rapidly detect tribromoanisole (TBA) at concentrations as low as 10 ppt. TBA has been identified as a common contaminant in the pharmaceutical, food and wine industries. It has been cited by the FDA as a cause for concern and has been the reason for a number of product recalls.
Screening and age monitoring of edible oils Screening and age monitoring of edible oilsWithin the edible oils industry, Lonestar can offer at-line screening and monitoring of raw material contamination; flavor thresholds; preservative levels; fatty acid methyl esters; and residues from cleaning-in-place.
Rapid Analysis of 4 Methyl Imidazole (4-MEI) Rapid Analysis of 4 Methyl Imidazole (4-MEI)The Lonestar Analyzer can detect and quantify 4-Methyl-Imidazole (4-MEI, also sometimes called 4-MI) within 15 minutes, in a range of backgrounds, including caramels and soy sauce. Deploy Lonestar to ensure compliance with Proposition 65 and improve plant throughput and productivity.
Detection of Melamine in Milk Detection of Melamine in MilkMelamine is an organic base that is widely used in plastics, adhesives, dishware and whiteboards. However, in China, it is sometimes illegally added into milk powder, liquid milk and other dairy products to increase the apparent protein content. A WHO white paper published in the wake of the 2008 Chinese milk scandal concluded that ingesting melamine can lead to the formation of kidney stones and other kidney damage. In 2012, The UN food standards body, Codex Alimentarius Commission, lowered the maximum limit for dairy products to 0.15mg/kg.

Monitorização e Controlo dos Níveis de água numa piscicultura

Monitorização e controle dos níveis de água numa uma piscicultura

A fazenda de peixes Villitaimen Osuuskunta em Kemijärvi (Lapónia) cresce vários tipos de peixe e os vende para usinas hidrelétricas. O abastecimento de água a toda a fazenda de peixes é garantida pela pressão hidrostática, como a fazenda não utiliza bombas de água. O fluxo de água é regulada manualmente, enquanto que sondas de nível KELLER PAA-36XW monitorar o nível ea temperatura da água. AGSM -2 é instalada no poço de tela e envia dados para um telefone celular via SMS informando sobre o nível da água e da temperatura.

Monitorização Remota dos Níveis de enchimento num Aquário

Na quinta de peixes Villitaimen Osuuskunta cresce truta, grayling e vários tipos de peixe branco do rio que fornece os seus próprios peixes mãe. Os peixes crescem na nos tanques até que, depois de dois a quatro anos, eles são vendidos a centrias hidrelétricas. As turbinas usadas nas referidas unidades prejudicam a migração dos peixes  de rio dentro do sistema; assim eles compram peixe, a fim de colocá-las em rios para reabastecer-los.
