				<content:encoded><![CDATA[<p><span style="font-size: 16px;"><i>By </i><i>Melissa Lind</i>, contributing writer</span></p>
<p><span style="font-size: 16px;">Both Steam-In-Place and Clean-In-Place methods are designed for automated cleaning and sterilization of food processing equipment without the requirement of dismantling and reassembly of the machinery. A common mistake that some manufacturers make is in the order of operations.</span></p>
<p><span style="font-size: 16px;">Clean-In-Place (CIP) is an automated method employed to remove particulate matter or food soil after processing. Steam-In-Place (SIP) operations are used to kill microorganisms in the same system. Some food processors employ SIP operations prior to CIP, which can reduce the effectiveness of the sterilization procedure. Both processes have their value in safety assurance in the food processing and manufacturing industry, but more attention is often paid to the CIP process. Your company may benefit from some SIP design and process tips to ensure your method is effective.</span></p>
<p style="padding-left: 30px;"><span style="font-size: 16px;">1 &#8211; CIP operations should always be performed prior to SIP processes. CIP removes food remnants and soils so that further microorganism growth cannot occur</span><br />
<span style="font-size: 16px;">2 &#8211; Process flow of CIP and SIP should be in the same physical direction to enable use of the same pipe and drain lines, avoiding dead ends and low-collection points</span><br />
<span style="font-size: 16px;">3 &#8211; Systems should be designed so the steam supply enters the equipment line at the highest or earliest point possible to ensure complete saturation by pushing out resident system gases</span><br />
<span style="font-size: 16px;">4 &#8211; Steam trap temperature sensors and blocking valves should be installed at the lowest physical point in the system to allow for monitoring at those spots where temperature may be cooler</span><br />
<span style="font-size: 16px;">5 &#8211; High point bleeds should be in place to allow for complete elimination of air at the end of the sterilization process</span><br />
<span style="font-size: 16px;">6 &#8211; Parallel steam paths should be avoided to eliminate the possibility for pressure variations in different paths resulting in lack of complete sterilization</span><br />
<span style="font-size: 16px;">7 &#8211; Ensure that the steam supply pressure and temperature at header is up to process specifications</span><br />
<span style="font-size: 16px;">8 &#8211; A time delay should be allowed after systems are fully pressurized and saturated with steam to allow components to achieve required temperature</span><br />
<span style="font-size: 16px;">9 &#8211; Once thermal hold has brought equipment to temperature, active steam flow should be continued for time required according to system standards</span><br />
<span style="font-size: 16px;">10 &#8211; Ensure that once SIP process is complete, system sterility is maintained as condensate is drained from system by establishment of sterility boundary</span></p>
<p><span style="font-size: 16px;">Not all manufacturers employ SIP as a separate process. Some choose an additional step of chemical sterilization rather than steam. However, for maximum effectiveness, both methods require that the CIP process be performed before sterilization to reduce the chance that any microorganism contamination will remain in the food line.</span></p>

				<content:encoded><![CDATA[<p><span style="font-size: 16px;">Mycotoxins are poisonous fungal metabolites that occur in food commodities colonized with filamentous fungi and in food products contaminated during processing and storage. Intake of mycotoxins poses a health risk to the consumer. Plant protection, adequate storage and GMP are often insufficient to keep mycotoxin levels below the worldwide established safety limits.</span></p>

				<content:encoded><![CDATA[<p><span style="font-size: 16px;"><b>Aging Cheese on Wooden Boards: No Change in FDA Regulations</b></span></p>
<p><span style="font-size: 16px;">The U.S. FDA welcomes an “open dialogue” with the artisanal cheesemaking community and state officials to discuss the safety of aging certain types of cheeses on wooden shelving. In a constituent update on June 11, the FDA said that recent reports that the agency is taking steps to end the practice of using wooden boards to age cheese “are not accurate.”</span></p>
<p><span style="font-size: 16px;">“We have not and are not prohibiting or banning the long-standing practice of using wood shelving in artisanal cheese. Nor does the FDA Food Safety Modernization Act (FSMA) require any such action,” according to the <a href="http://www.fda.gov/Food/NewsEvents/ConstituentUpdates/ucm400808.htm">update </a>provided by FDA press officer Lauren E. Sucher.</span></p>
<p><span style="font-size: 16px;">Concerns that the FDA is enforcing regulations about wooden shelving received widespread attention after an FDA inspection of several New York state cheesemakers. A January 2014 communication from the agency’s Center for Food Safety and Applied Nutrition to the New York State Department of Agriculture and Markets’ Division of Milk Control and Dairy Service, in response to questions from New York State, was widely interpreted as a policy statement that the aging of cheese on wooden boards would no longer be permitted. The FDA has now made clear that the language used in that communication “may have appeared more definitive than it should have, in light of the agency’s actual practices on this issue.”</span></p>
<p><span style="font-size: 16px;">The FDA has no regulations that specifically address the use of wooden shelving in cheesemaking, and it “has not taken any enforcement action based solely on the use of wooden shelves,” according to the update. Enforcement action has been taken, however, when <i>Listeria monocytogenes</i> was identified at facilities that use wooden shelving. Since 2010, the agency has found the bacterium in more than 20 percent of inspections of artisanal cheesemakers, but the agency has no data directly linking these contaminations with use of wooden shelving.</span></p>
<p><span style="font-size: 16px;">Current FDA regulations state that utensils and other surfaces in contact with food must be adequately cleanable and properly maintained, and it “has expressed concern about whether wood meets this requirement and these concerns have been noted in its inspectional findings.&#8221;</span></p>
<p><span style="font-size: 16px;">A position statement from the American Cheese Society asserts that aging cheese on wood has a “long track record of safety,” and that wood can be safely used when “all surfaces are properly cleaned and maintained using sanitation steps that assure the destruction of pathogens.” A report in <i>Dairy Pipeline</i>, published by the Wisconsin Center for Dairy Research, reaffirms that wood boards do not “seem to present any danger of contamination by pathogenic bacteria as long as a thorough cleaning procedure is followed.” </span></p>

				<content:encoded><![CDATA[<p><span style="font-size: 16px;">Nelle industrie alimentari, farmaceutiche e cosmetiche, valutare l’effetto della radiazione solare sui propri prodotti e sul loro packaging è fondamentale.  Dovunque c’è luce esiste infatti il rischio di reazioni foto-indotte. Nel caso di alimenti o bevande ciò ha un impatto sui coloranti, vitamine, fragranze ed essenze oltre che sull’omogeneità dei prodotti stessi.</span></p>
<p><span style="font-size: 16px;">Sottoposti alla luce i colori possono trasformarsi per tono o intensità. Il gusto ed il profumo possono alterarsi. Le vitamine possono disperdersi. Il packaging può apparire vecchio o di scarsa qualità.</span></p>
<p><span style="font-size: 16px;">Poter svolgere test di simulazione in tempi accelerati anche di 50 volte rispetto al reale, può diventare un fattore di successo per l’azienda.</span></p>
<p><span style="font-size: 16px;"> Essere rapidi nel fornire informazioni sicure e ripetibili nella fase di formulazione dei propri prodotti, nel loro sviluppo, nella gestione di eventuali reclami e nella preparazione della documentazione necessaria alla loro commercializzazione, oggi è possibile grazie ad appositi strumenti.</span></p>
<p><span style="font-size: 16px;">Noti e largamente diffusi ad esempio nell’ambito farmaceutico e cosmetico, per l’effettuazione in tempi accelerati delle prove ICH e Colipa, questi strumenti stanno diventando una risorsa anche in ambito R&amp;D e Controllo Qualità per l’industria alimentare.</span></p>
<p><span style="font-size: 16px;">Nati per degradare in tempi ridotti prodotti come inchiostri, vernici, carta, tessuti e plastica garantiscono l’ottenimento di risultati attendibili, riproducibili e confrontabili scientificamente.</span></p>
<p><span style="font-size: 16px;">Conosciuti come SUNTEST e Xenotest, questi strumenti sono equipaggiati con una speciale sorgente allo Xenon che è il cuore di queste attrezzature che, oltre ad irradiare, permettono di controllare anche la temperatura e se necessario anche l’umidità.</span></p>
<p><span style="font-size: 16px;">In questi strumenti, la luce allo Xenon viene intercettata da speciali filtri ottici, selezionabili in funzione di ciò che si vuole simulare. In questo modo si possono produrre gli effetti della radiazione solare all’aperto, all’interno di edifici nonché la luce artificiale tipica dei supermarket.</span></p>
<p><span style="font-size: 16px;">In questo modo ciò che è sensibile nel range UVB, sia ciò che reagisce nell’ambito UVA o nel Visibile sarà indotto alla modificazione e non mancherà inoltre l’apporto della radiazione IR necessaria per ottenere un riscaldamento naturale e  realistico del prodotto. La temperatura infatti è un importante fattore di stress e di accelerazione dei processi di degradazione  che è necessario considerare e controllare.</span></p>

				<content:encoded><![CDATA[<p><span style="font-size: 16px;"><img alt="AROUNDLABNEWS-txt-note-applicative" src="http://www.aroundlabnews.com/it/wp-content/uploads/2013/07/AROUNDLABNEWS-txt-note-applicative.jpg" width="600" height="100" /></span></p>
<p><span style="font-size: 16px;">I microrganismi coinvolti nella preparazione di alimenti o in processi alterativi o responsabili di infezioni e tossi-infezioni sono generalmente organizzati in “gruppi” sulla base di comuni caratteristiche colturali e metaboliche. Questi “gruppi” non hanno solitamente un valore tassonomico. I principali gruppi microbici di interesse alimentare sono di seguito riportati:</span></p>
<p><span style="font-size: 16px;">-Batteri lattici</span></p>
<p><span style="font-size: 16px;">Si tratta di batteri Gram positivi che producono quantità apprezzabili di acido lattico a partire da carboidrati. Sono generalmente ritenuti NON patogeni. (Lactobacillus, Leuconostoc, Pediococcus, Streptococcus, Lactococcus, Aerococcus, Tetragenococcus, Oenococcus, Vagococcus, Carnobacterium).</span></p>
<p><span style="font-size: 16px;">-Batteri acetici (Acetobacter aceti)</span></p>
<p><span style="font-size: 16px;">-Batteri propionici</span></p>
<p><span style="font-size: 16px;">Si tratta di specie batteriche che producono quantità apprezzabili di acido propionico (Propionibacterium freudenreichii) e sono utilizzate nella produzione di formaggi tipo Emmenthal.</span></p>
<p><span style="font-size: 16px;">-Batteri proteolitici</span></p>
<p><span style="font-size: 16px;">In questo gruppo sono riuniti tutti generi microbici di interesse alimentare caratterizzati da una spiccata attività proteolitica dovuta alla produzione di proteinasi extracellulari. (Micrococcus, Staphylococcus, Bacillus, Clostridium, Pseudomonas, Alteromonas, Flavobacterium, Alcaligenes, Enterobacteriaceae, Brevibacterium)</span></p>
<p><span style="font-size: 16px;">-Batteri lipolitici</span></p>
<p><span style="font-size: 16px;">Diverse specie appartenenti ai generi Micrococcus, Staphylococcus, Pseudomonas, Alteromonas, Flavobacterium sono caratterizzati dalla produzione di lipasi extracellulari.</span></p>
<p><span style="font-size: 16px;">-Batteri Saccarolitici</span></p>

				<content:encoded><![CDATA[<p><span style="font-size: 14px;">I polifenoli di maggiore interesse produttivo sono indubbiamente gli antociani, pigmenti responsabili del colore rosso, e i tannini, con il loro impatto organolettico sui vini (astringenza, struttura, secchezza, corpo…). Se la valutazione dei primi è relativamente facile da realizzare, per quanto riguarda i secondi, invece, benché negli anni siano stati messi a punto un gran numero di metodi analitici, non sono ancora stati svelati tutti i misteri che circondano queste molecole.</span></p>
