title: Acerola by-product as a renewable source of bioactive compounds: arabic gum and maltodextrin nanocapsules

description: Abstract Acerola industrial by-products present high levels of antioxidant compounds. Encapsulation technology has shown to be of great importance in the food industry. In this context, better nanoparticles are indicated in aiming to enrich food products with bioactive compounds. Five formulations were analyzed for yield, size distribution and zeta potential, infrared spectroscopy, encapsulation efficiency and doping. The yield data presented values from 38.01% to 44.34%. The nanoparticles had sizes varying from 27.12 nm to 308.80 nm and negatively charged surfaces. The encapsulation efficiency was quantified based on the vitamin C content, total extractable polyphenols and antioxidant activity according to specific methodology taking into account the different compounds ranging from 25.44% to 69.37%; 66.45% to 99.56% and 2.24% to 6.54%, respectively. The above data indicate that nanoparticles made with acerola by-products and arabic gum/maltodextrin are promising as natural food additives, with high levels of bioactive compounds.

title: Fibrinolytic bacteria of Indonesian fermented soybean: preliminary study on enzyme activity and protein profile

description: Abstract A number of fibrinolytic enzyme producing microorganisms have been identified in various fermented food in Asia, such as from Red Oncom, Tempe, Terasi (Indonesia), Natto (Japan), Douchi, Soy paste (China), Meju, Kimchi, Jeot-gal, Tofuyo, Chungkook-jang, Soybean paste and Doen-jang (Korea). The high protein content in soybean is potential to promote the growth of proteolytic and fibrinolytic producing microbes. This study investigated several fibrinolytic bacteria, isolated from the moromi stage of the fermented soysauce production. The fibrinolytic activities of the isolates were confirmed in a fibrin plate assay, and all 3 potential isolates (K1, K2, and K3) were identified as Gram positive, rod shaped, and spore forming bacteria. Moreover, analysis of the sequences encoding 16S rRNA gene, revealed K1 as Bacillus cereus, K2 as Bacillus subtilis, and K3 as Bacillus cereus. SDS PAGE analysis demonstrated different protein profile of the cell free supernatant of isolates grown in LB media during fermentation, which ranged from 18.40-45 kDa.

title: Effect of dihydroferulic acid obtained from fermented rice bran extract on neuroprotection and behavioral recovery in an ischemic rat model

description: Abstract This study aimed to evaluate whether dihydroferulic acid (dFA) promoted the viability of H2O2-treated PC12 cells and functional recovery from ischemic injury. The animals were divided into four groups for the study: (1) the vehicle treated (saline, 1 mL/kg), (2) dFA 5 mg/kg treated, (3) dFA10 mg/kg treated, and (4) dFA 20 mg/kg treated groups. Neurological deficit was evaluated using the modified neurological severity score. Real-time polymerase chain reaction analyses were performed with the protein disulphide isomerase (PDI), nuclear factor-E2-related factor 2 (Nrf2), nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) genes. Immunohistochemical analysis was performed with the Iba-1 and MFG-E8 genes. dFA treatment improved the reduced viability of PC12 cells induced by H2O2 in a dose-dependent manner. Only 50 μM of dFA significantly enhanced the transcription levels of antioxidant genes and neurotrophic factors compared to the vehicle group. In vivo dFA administration exerted a neuroprotective effect by reducing the infarct volume and enhancing behavioral function following cerebral ischemia. dFA treatment protected neuronal cells from ischemic injury and increased the transcription levels of anti-oxidant genes (PDI and Nrf2) and neurotrophic factors (BDNF and NGF). dFA treatment decreased the expression of Iba-1 and MFG-E8 genes, which signal neural cell death.

title: Application of self-organizing maps to evaluate the influence and behavior of the film formed during salting of Prato cheese

description: Abstract Problems related to high blood pressure have led consumers to choose foods with low levels of sodium chloride, and an alternative to reduce the salt content of this salt is its partial replacement with KCl. In order to not affect the sensory properties of cheese, salting was performed using a solution containing 70% of NaCl and 30% of KCl in a static and dynamic system. During the salting process by immersion, the mass transfer is affected by the formation of a film on the cheese surface. The analysis of the diffusion of salts in the film can be performed using self-organizing map (SOM) combined with the Finite Element Method (FEM). Through these tools, a greater influence of the film was observed when the static system was applied and that the diffusion is different according to the studied position. On the biosolid sides the diffusion was more pronounced than in the center, indicating a decrease in the film thickness towards the edges. The SOM combined with 3D modeling showed to be an efficient tool to investigate the formation, influence and behavior of the film during the diffusion of Na+ and K+ on salting of Prato cheese.

title: Effects of pectin and tomato paste as a natural antioxidant on inhibition of lipid oxidation and production of functional chicken breast sausage

description: Abstract In this study antioxidant effects of pectin and tomato paste (TP) on lipid oxidation and production of functional chicken breast sausage during refrigerated storage for 14 days were evaluated. Raw chicken sausage samples were enriched with different levels of TP containing 0, 1, 2 and 10% and 1% pectin, and peroxide value (PV), thiobarbituric acid reactive substances (TBARS) and sensory attributes were evaluated periodically for 14 days of storage at 4 °C. Although after 1 day of storage TP treatments at level of 1% did not exert any antioxidant effects on TBARS, PV varied for all treatments except control and remained lower than 8 meq O2/kg throughout the storage time. During refrigerated storage, formation of lipid oxidation products increased from 2.8 to 15.2 meq O2/ kg for PV and 0.064 to 0.38 mg malondialdehyde (MDA)/kg in the TBARS test, respectively. At the end of storage time, the PV and MDA value in chicken sausage treated with 1%, 2% and 10% TP decreased by 51 and 19%, 73 and 69%, and 71 and 82% (P &lt;0.05), respectively. The results of sensory evaluation showed that panelists preferred functional sausage containing 2% of TP and higher levels of TP altered the visual appearance of product.

title: Characterization of traditional Algerian cheese “Bouhezza” prepared with raw cow, goat and sheep milks

description: Abstract “Bouhezza” is an Algerian traditional fermented soft-ripened cheese, found and consumed in the Northeast of Algeria. The objective of this study was to explore the preparation process (traditional making diagram) of “Bouhezza” cheese and to study the effect of the type of raw milk (cow, goat and sheep) on the yield and organoleptic characteristics of the fresh “Bouhezza” cheese. “Bouhezza” cheese was handmade in a traditional way using milk of three species (cow, goat and sheep). The milk used has been the subject of physicochemical and bacteriological analysis. Cheese yield for sheep's milk is higher (p &lt; 0.05) than cheese yield for cow's and sheep’s milk. For sensory analysis, score registered for cheese of cow's milk ≥ 5 suggested higher acceptability for this cheese. Here, we exposed the “Bouhezza” cheese, its history, origin and manufacturing processes. From the physicochemical and bacteriological analysis of milk, results show that all criteria analyzed respond almost to the required standard. The sensory qualities of the three types of cheese show that cow cheese was classified as the most satisfactory cheese for the majority of criteria (taste. color and texture). Finally, and for higher yield, results supported the use of sheep milk as a raw material.
