<p class="Els-Abstract-text">Garlic is a natural source which has abundant organosulfur constituents. Garlic is divided into water-soluble organosulfur constituents mainly SAC (S-allylcystein), NAC (N-acetylcysteine) and oil soluble organosulfur constituents such as DATS (diallyl trisulfide), DADS (diallyl disulfide), DAS (diallyl sulfide). The aim of this research was to compare the bioactive constituents and antioxidant activity between garlic water-soluble and garlic oil. Garlic water-soluble constituents were identified by Liquid Chromatography–Mass Spectrometry (LC-MS) and five constituents were found, namely N-acetylcysteine (NAC), cysteinyl-alanine, phenol-2-2-benzoxazolyl and two unknown constituents. The GC-MS chromatogram also showed three main constituents present in garlic oil as diallyldisulphide (DADS), diallyltrisulphide (DATS) and D-limonene. Interestingly, garlic water-soluble extract had higher antioxidant activity 70 %  ± 0.02 % in comparison with garlic oil 58 % ± 0.07 %. This study conducts a novel preparation of garlic water-soluble for enhancing antioxidant properties on garlic novel preparation.</p><p> </p>

Water Soluble Extract

The use of sourdough fermentation and whole grain flours in baked goods manufacturing are known to enhance their functional and nutritional features. In this context, it is necessary to select the most suitable lactic acid bacteria strains and flour combination to achieve this goal. A characterization of 70 lactobacilli strains based on pro-technological and nutritional properties was carried out. The screening allowed the selection of 10 strains that were used to ferment sourdoughs made with two varieties of common wheat, the conventional red-grained cv Aubusson, a blue-grained variety rich in anthocyanins cv Skorpion, and a hull-less barley variety, cv Rondo. From each fermented sourdough, a water soluble extract was obtained and evaluated for its antioxidant activity performed on cultured cells (RAW 264.7 murine macrophage) by assaying Reactive Oxygen Species (ROS) content. Sourdoughs made with pigmented wheat and barley, had an antioxidant activity greater than that recovered in those made with conventional wheat flour, in spite they have been inoculated with the same LAB strains. Results highlighted the interdependence between flour and the inoculated lactic acid bacteria that has to be taken into account for the development of healthy breads exploiting high functional value cereals through biotechnological processes.

Water Soluble Extract

We isolated a water-soluble extract, PG101, from cultured mycelia of Lentinus lepideus. Treatment of human peripheral blood mononuclear cells (PBMCs) with PG101 increased levels of TNF-α, IL-1β, IL-10, and IL-12 by 100- to 1000-fold, whereas GM-CSF and IL-18 were activated by an order of magnitude. On the contrary, IFN-γ and IL-4 were not affected. The response to PG101 occurred in a dose- and time-dependent manner. From the human PBMCs treated with PG101, TNF-α was a first cytokine to be activated, detectable at 2 hr post-treatment followed by IL-1β at 6 hr post-treatment. IL-12 and IL-10 were the next to follow. GM-CSF and IL-18 both showed significant increases 24 hr after treatment. When PBMCs were sorted into various cell types, monocyte/macrophages, but not T and B cells, were the major target cell type responsive to PG101. Consistent with this result, the profile of cytokine expression upon PG101 treatment was comparable between PBMCs and a human promonocytic cell line (U937), whereas cell lines of T cell and myeloid origins did not respond to PG101. Data from a transient transfection assay involving specific reporter plasmids indicated that cellular transcription factor such as NF-κB, but not AP-1, was highly activated by PG101. Results from a gel retardation assay and the experiment involving a specific NF-κB inhibitor confirmed the involvement of NF-κB. Despite its significant biological effect on various cytokines, PG101 remained nontoxic in both rats and PBMCs even at a biological concentration approximately 20 times greater. PG101 demonstrates great potential as a therapeutic immune modulator.

<p>Considering the need for new products to meet the portion of the population with lactase enzyme deficiency, the study processed and characterized the physical, physical-chemical and sensory parameters of a dulce de leche made with soy-based extract. The research was developed at the Food Engineering Laboratory of the Federal University of Campina Grande. The soybean milk used in the preparation of the product was the UHT type and pasteurized cow’s milk, both purchased commercially from the city of Campina Grande, PB. Three sweet formulations were prepared: the first one containing 100% whole bovine milk; the second one with 100% water-soluble soy extract and the last one with 50% water-soluble soy extract and 50% whole milk. There were significant differences in all physicochemical analyses, except for the ash one. Regarding the addition of the soybean water-soluble extract in the dulce de leche, this procedure altered the traditional flavor, resulting in less acceptance of the product and 90% of the judges declared that they would not buy that. Through the instrumental analyses, it was verified that the addition of water-soluble soybean extract changed statistically (p &lt;0.05) the characteristics of color and texture</p>
