Hydrogels can offer many opportunities for drug delivery strategies. They be used on their own, or benefits further exploited in combination with other nanocarriers. Intelligent hydrogels that react to changes the surrounding environment utilized as gatekeepers and provide sustained on-demand release. In this study, a hybrid nanosystem temperature- pH-sensitive was prepared from MCM-41 nanoparticles grafted newly synthesized thermosensitive hydrogel (MCM-41/AA-g-PnVCL). The initial particles...

The antimicrobial activity of polyphenol-enriched extracts from industrial plant by-products (strawberry and bilberry press residues distilled rose petals) against probiotic lactic acid bacteria (Lactobacillus delbrueckii subsp. bulgaricus – S10 S19; Lactobacillus rhamnosus YW S25; gasseri S20; Streptococcus thermophilus S13 S32) was investigated. minimum inhibitory concentration (MIC) in most strains tested found to be relatively high (from 6.25 mg.mL-1 12.50 mg.mL-1). maximum polyphenols...

Agar, a naturally occurring polysaccharide, has been modified by grafting it with acrylic (AcA) and methacrylic (McA) acid monomers, resulting in or grafted polymer (AA-g-AcA AA-g-McA) pH-sensitive swelling behavior. Different ratios between agar, initiator were applied. The synthesized grades of both new series characterized using FTIR spectroscopy, NMR, TGA, DSC, XRD to ascertain the intended grafting. percentage (% G), efficiency GE), % conversion C) calculated, models optimal...

The present study aimed to investigate the effect of somatic cell count (SCC) raw cow's milk on volatile organic compound (VOC) profiles yoghurt. Test yoghurt samples were produced from three batches with low, medium and high SCC, respectively. VOCs determined by gas chromatography–mass spectrometry (GC–MS) analysis. A lower diacetyl acetoin content a higher 2‐heptanone, butanoic hexanoic acids established in SCC above 1 000 cells/cm 3 . increased had negative

Abstract : Chilled and frozen chicken breast thigh meat were stored at +4±1 oC - 20±1 oC, respectively. Maillard reaction between ribose proteins of the samples was initiated. The changes in ribose-induced rate during chilled storage evaluated on bases corrected absorbance values (A420*) bovine melanoidin equivalent (mg BME/g). Application BME as a measure enables comparability data obtained by different spectrophotometers. It found that for more than 15 days significantly (P<0.05) lower...

In the production of ethanol from cereal grains, besides main product which is ethanol, there are olso very valuable by-product that can be used as animal feed. The dried distilled grains with solubles (DDGS) quite rich in protein and other nutrients. With ever-increasing cost soybeans corn, many scientists studying possibilities using DDGS poultry nutrition. aim present study was to determine effect including corn probiotic compound feeds on productive, slaughter performance some meat...

The enrichment of probiotic dairy products with polyphenol extracts from different plant origins is a good approach to enhance the beneficial health effects functional foods. aim present study was evaluate effect rose (Rosa damascena Mill.) petals extract (RPPE) fortification on lactic acid production and viability Lactobacillus delbrueckii subsp. bulgaricus S19 ( Lb. ), rhamnosus YW (Lb. ) Streptococcus thermophilus S13 (S. in fermented milk samples during refrigerated storage. RPPE...

The production of grain-based bioethanol is increasing due to the rising demand for biofuels and global decline in fossil fuel sources. Distiller’s dried grains with solubles (DDGS) from corn or wheat are main by-product fermentation, primarily through dry milling technology, have been used as low-cost animal feed. With increase ethanol grains, DDGS also increases. Several studies found that has high nutritional value but variable composition, researchers ways enhance its quality safety....

In recent years, there has been a growing interest in incorporating phytogenic feed additives (PFAs) into broiler chicken diets as potential alternatives to traditional growth-promoting additives. This study evaluated the economics of individually either six different dried herbs or their essential oils diets: chamomile, rosemary, lavender, oregano, thyme and St. John's wort. A total 390 day-old male chicks (Ross 308) were randomly divided 13 groups 30 with three replicates (10...

Abstract The experimental investigation of reinforced concrete structures is a high time resource consuming process. One the best solutions to reduce consumed finite element simulation those structures. biggest challenge for engineers modeling choose proper mathematical model who can represent with good accuracy mechanical behavior. study focused on Numerical behavior column - short corbel assembly repaired and strengthened by bonding composite materials. presented developed in two steps....

The objective of the present work was to investigate effect somatic cell count (SCC) raw cow’s milk on lipolysis and oxidative processes in farmer cheese. cheese samples were produced from three different batches low (about 100,000 cells/mL, batch L), medium (between 500,000 600,000 M), high (above 1,500,000 H) SCC. aged cold-stored at 4 ± 1°C for ten months, respectively. Lipolysis evaluated by monitoring changes fatty acid values peroxide values, as well profile. Results indicated...
