<description>Evaluation of polyphenolic content of the local moldovan fruits (apples, pears, quinces)
CEABAN, Dmitry; PUSHOY, Vladimir
In this study we aim to evaluate the potential of local Moldovan fruits, namely quince (Muscat, Port), pear (Conference, Victoria), apple (Golden, Jonathan) as sources of beneficial and bioactive compounds (polyphenols and antioxidants), studying the effect of different extraction solvents. The samples were followed by extraction with ethanol in different concentrations (25%, 50%, 75%). They were taken both from the pulp and from the surface of the products. The results show that the polyphenolic content is higher in the samples extracted in the concentration of 75% ethanol and taken from the surface of the product. This correlation is positive for quince and pear, and negative for apple, because the highest polyphenolic content in apples was found in the concentration of 25% ethanol.

<title>Влияние процесса озонирования на содержание нитратов в клубнеплодах</title>

<description>Влияние процесса озонирования на содержание нитратов в клубнеплодах
ЗОЛОТАРЕВА, Алена; БОИШТЯН, Алина
Нерациональное применение минеральных и азотных удобрений приводит не только к увеличению урожайности, но и существенно изменяет экологию и качество урожая. В клубнеплодах происходит избыточное накопление нитратов, скармливание которых оказывает отрицательное воздействие не только живой организм, но и приводит к потере качества и количества продукта. Целью данной работы было исследование количества нитратов в различных клубнеплодах местного производства и предложен способ по их снижению путем озонирования. Данное исследование состояло в том, что при помощи процесса озонирования уменьшить количество нитратов и тем самым улучшить качество продукта.

<description>Utilizarea materiei prime autohtone pentru obţinerea cărbunelui activat
GUŢU, Crina
Cărbunele activat este un sorbent microporos cu o suprafaţă foarte mare de adsorbţie. Este un ingredient purifiant de excepţie datorită porilor mici care au rolul de a mări suprafaţa de adsorbţie a produşilor toxici.Cărbunele activat elimină din apă mulţi contaminanţi, agenţi de dezinfecţie chimici, culoarea, mirosulşi gustul neplăcut, turbiditatea, clorul liber, insecticidele, ierbicidele, hidrocarburi aromatice polinucleare, substanţele organice volatile, benzenul, şi alţi contaminanţi ce pot fi prezenţi în apă.

<title>Impactul tratamentului termic asupra carotenoidelor din dovleac</title>
<link>https://repository.utm.md/handle/5014/2891</link>
<description>Impactul tratamentului termic asupra carotenoidelor din dovleac
POPESCU, Adelina; CEREVATÎ, Irina
Dovleacul prezintă o sursă importantă de carotenoide cu activitate provitaminei A, luteină,&#13;
zeaxantină, licopen, fibre alimentare, substanțe minerale și compuși fenolici având acțiuni benefice asupra organizmului uman. Utilizarea dovleacului ca component a produselor alimentare sporește valoarea nutrtivă a produsului finit. În acest articol sunt prezentate datele determinării prin metoda spectrofotometriei UV/Vizibilă a βcarotenului, zeaxantinei si licopenului din dovleacul supus diferitor tratamente termice.
