  • Posibiliti de utilizare a pulsurilor de lumina n industria alimentarAnca NicolauFacultatea de tiina i Ingineria AlimentelorUniversitatea Dunarea de Jos Galati

  • Contribuia Facultii de tiina i Ingineria Alimentelor din Galai la studiul Posibilitilor de utilizare a pulsurilor de lumina n industria alimentarAnca NicolauFacultatea de tiina i Ingineria AlimentelorUniversitatea Dunarea de Jos Galati

  • Tehnologia IPL (Intense Pulsed Light) Tehnologia care utilizeaz lumin cu intensitate ridicat pentru perioade de timp foarte scurte. Tehnologie alternativ de procesare a alimentelor Tehnologie nou/Tehnologie emergentTehnologie de procesare minim care utilizeaz o metod atermic

  • Producerea pulsurilor de lumin Lmpi flash: - conin xenon- 1-20 flash-uri per secundLumin: - lumin de 20000 de ori mai intens dect lumina soarelui - spectru 170-2600 nm: 25% UV, 45% VIS, 30% IR- se filtreaz lungimile de und ce pot afecta culoarea i aroma produselor alimentare

  • Costuri asociate costuri comparabile cu ale procedeelor termice convenionale:- 0,4 US centi/litru la tratarea lichidelor limpezi - 1 US cent/m2 la tratarea suprafetelor solide cu 4J/cm2

  • AplicaiiSterilizarea materialelor de ambalare utilizate n ambalarea asepticSterilizarea continu a lichidelor transparentePasteurizarea suprafeelor alimentelor solide ambalate n folie transparent

  • Distrugerea sporilor de Aspergillus cinamomeus pe ambalaj din hrtie-folie de polietilenControl sample 0.497 J/cm2 0.716 J/cm20.977 J/cm2 M. Turtoi i A. NicolauFacultatea de tiina i Ingineria Alimentelor Galai

  • AplicaiiUscarea alimentelor- frunze de plante aromate - fructe - rdcini

  • Influena uscrii cu pulsuri de lumin asupra coninutului de vitamin C din mcee M. Turtoi i I. BanuFacultatea de tiina i Ingineria Alimentelor Galai
