The residue generated from the processing of Tacinga inamoena (cumbeba) fruit pulp represents a large amount of material that is discarded without proper application. Despite that, it is a raw material that is source of ascorbic acid, carotenoids and phenolic compounds, which are valued in nutraceutical diets for allegedly combating free radicals generated in metabolism. This research paper presents a study focused on the mathematical modeling of drying kinetics and the effect of the process on the level of bioactive of cumbeba residue. The experiments of cumbeba residue drying (untreated or whole residue (WR), crushed residue (CR) and residue in the form of foam (FR)) were carried out in a fixed-bed dryer at four air temperatures (50, 60, 70 and 80 °C). Effective water diffusivity (Deff) was determined by the inverse method and its dependence on temperature was described by an Arrhenius-type equation. It was observed that, regardless of the type of pretreatment, the increase in air temperature resulted in higher rate of water removal. The Midilli model showed better simulation of cumbeba residue drying kinetics than the other models tested within the experimental temperature range studied. Effective water diffusivity (Deff) ranged from 6.4890 to 11.1900 × 10−6 m2/s, 2.9285 to 12.754 × 10−9 m2/s and 1.5393 × 10−8 to 12.4270 × 10−6 m2/s with activation energy of 22.3078, 46.7115 and 58.0736 kJ/mol within the temperature range of 50–80 °C obtained for the whole cumbeba, crushed cumbeba and cumbeba residue in the form of foam, respectively. In relation to bioactive compounds, it was observed that for a fixed temperature the whole residue had higher retention of bioactive compounds, especially phenolic compounds, whereas the crushed residue and the residue in the form of foam had intermediate and lower levels, respectively. This study provides evidence that cumbeba residue in its whole form can be used for the recovery of natural antioxidant bioactive compounds, mainly phenolic compounds, with the possibility of application in the food and pharmaceutical industries.

Abstract Accordingly, with the benefits of high temperature with short time treatment, microwave irradiation has conquered novel extraction technology to volarize food wastes. Compared to other unconventional ways, microwave-assisted-extraction (MAE) is superior for its accordance with green solvents due to the mode of heating which based on the dielectric constant level of solvents. In this study, the extraction processes of bioactive compounds from waste parts of beetroot were accomplished using a home-use microwave oven. Aside from peel; stalk and flesh were utilized for extraction at three coded levels of process conditions (low, medium, and high) for comparison. Control samples were prepared at 70ºC for 1 h extraction time with 1:10 w/v solvent ratio. Spectrophotometric analysis was performed for approaching bioactive compounds existing in specific parts of the beetroot. Compared to the control, approximately 2.2 times of total betalains, phenolics, flavonoids, and the relevant antioxidants were scavenged at 800 W of microwave power together with 150 s of extraction period following the descending order: peel, flesh, and stalk. Our observation is a prove of the high extraction efficiency of green solvent since pure water solvent brought more amount of specific bioactive compounds than aqueous ethanol under the same studied process conditions.

ABSTRACT: Extraction conditions are an important factor in the process of obtaining bioactive compounds from plant matrix. These compounds differ structurally. Structures of phyto-compounds and their interactions with other food ingredient are not fully known, while these two aspects should play a significant role in extrahents choice and determination of extraction process conditions. Mulberry (Morus alba) is a plant growing in Asia, which fruits are rich in bioactive ingredients and high anti-oxidative potential. In our study we analyzed mulberry fruits extracts differing in the extra hent applied: acetone, methanol, ethanol and water. All tested extracts possessed rich polyphenolic composition and radical scavenging ability. The significant differences among the extracts in phenolic acids and flavonoids compositions were noticed, where the highest values were observed for acetone extract. The extrahent applied affects the antioxidative profile of tested samples, as well. The highest scavenging activity against ABTS was observed for acetone and ethanol extracts, while the poorest activity had water extract. Similar results were provided for ferrous ion reducing test and Fe chlating activity (acetone>ethanol>methanol>water). These results are helpful when selecting solvents with appropriate bioactive compounds compositions and high phytochemical profiles to be used as ingredients in supplements, as well as in functional foods.

AbstractA fraction of the most valuable bioactive compounds in beer comes from hop’s polyphenols, mainly flavonoids, some of which are unique to inflorescences of that flowering plant. Although far from pharmacologically relevant concentrations, the intake of low doses of xanthohumol and related prenylflavonoids found in beer contributes to significant preventive actions with regards to certain diseases, such as cardiovascular and neurodegenerative, as well as to distinct chemopreventive effects on certain cancer types. Hence the efforts to explore both ingredients and methods able to enhance the concentration of such bioactive compounds in the final beers. A novel brewing method assisted by hydrodynamic cavitation was proved able, under suitable process conditions, to retain or generate higher amounts of xanthohumol, desmethylxanthohumol and 6-geranylnaringenin, extending recent evidence about different food and respective bioproducts, as well as adding to its distinct benefits to the brewing process.

With new consumption trends and mindset of a healthier way of life, there is an increasing demand for functional foods. To provide stable and functional products to consumers, the stability of the active compounds must be preserved during the processing of food. For this purpose, encapsulation techniques have been used in various industries in order to overcome problems such as stability, low solubility, and degradation under process conditions for food applications. Electrospinning and electrospraying are two highly versatile and scalable electrohydrodynamic methods, which have gained increasing attention in the various encapsulation applications. This review will give readers an overview of the latest electroencapsulation (electrospraying and electrospinning) of natural bioactive compounds for functional foods applications.

AbstractThe study concerns the effects of drying process conditions (40, 50, 60°C) on the contents of bioactive compounds in Scots pine (Pinus sylvestris L.) shoots as well as the yield and composition of essential oils. The obtained dry material was examined for the total contents of polyphenols and the antioxidant activity as well as the content of vitamin C. The material was examined by using the HS-SPME method, and the composition of the essential oils was determined using gas chromatography method (GC-MS). The highest contents of bioactive compounds were found in the material subjected to drying at 40°C. The highest yield of essential oils (0.63 ml 100 g−1 d.m. of the material) was obtained from the pine shoots dried at 40°C.

Titanium nitride (TiN) films have historically been used as diffusion barrier between silicon and aluminum, as an adhesion layer for tungsten deposition and as an interconnect material etc. Recently, the role of TiN films as contact barriers in very large scale silicon integrated circuits (VLSI) has been extensively studied. TiN films have resistivities on the order of 20μ Ω-cm which is much lower than that of titanium (nearly 66μ Ω-cm). Deposited TiN films show resistivities which vary from 20 to 100μ Ω-cm depending upon the type of deposition and process conditions. TiNx is known to have a NaCl type crystal structure for a wide range of compositions. Change in color from metallic luster to gold reflects the stabilization of the TiNx (FCC) phase over the close packed Ti(N) hexagonal phase. It was found that TiN (1:1) ideal composition with the FCC (NaCl-type) structure gives the best electrical property.
