Thermal Stabilization of HEWL by Adsorption on Biochar | Chapter 11 | New Advances in Materials Science and Engineering Vol. 2

The heat stress tolerance of hen egg white lysozyme (HEWL) was markedly enhanced by the adsorption of HEWL on bamboo charcoal powder (BCP), which is a kind of biochar. HEWL was firmly adsorbed on BCP even at high temperatures. The secondary structure of HEWL was altered to some extent by the adsorption of HEWL on BCP. The remaining activity of BCP-adsorbed HEWL exhibited more than 20% after the incubation for 30 min at 90°C although that of free one was hardly observed. Moreover, the half-life of BCP-adsorbed HEWL was 13 min at 90°C while that of free one was 4 min.

Consensus Summit: Lipids and Cardiovascular Health in the Nigerian Population | Chapter 09 | Current Trends in Food Science Vol. 1

Aims: To issue a consensus statement on Lipids and Cardiovascular Health and the impact of their interrelationship in Nigerian Population. Study Design: Experts from a range of relevant disciplines, deliberated on different aspects of Lipids and Cardiovascular Health in the Nigerian Population at a Summit. Place and Duration of Study: The Summit was held in April 2016 at the Nigerian Institute of Medical Research. Methodology: Presentations were made on central themes after which expert participants split into four different groups to consider the questions relevant to different sub themes of the title. Consensus was arrived at, from presentations of groups at plenary. Conclusion: With the increase in the prevalence of NCDs, especially Cardiovascular Disease in Nigeria, and the documented evidence of deleterious effects of lipids, the expert panel called for an urgent need to advocate for the general public and health professionals to make heart-friendly

A Review on Gongronema latifolium, an Extremely Useful Plant with Great Prospects | Chapter 11 | Recent Advances in Biological Research Vol. 3

Gongronema latifolium is a plant that has a wide range of nutritional and ethnomedical uses in different tropical African communities. Scientific reports on the chemical composition and bioactivity (anti-inflammatory, antimicrobial, antidiabetic, antioxidant, anticancer and allelopathic properties) of the plant material by different authors are discussed in this review. Future prospects of the plant extracts in the areas of herbal formulations, food preservation, alcoholic fermentation and beer production, drug discovery and allelopathy are also highlighted.

An Overview of Ultrasonic Technology and Its Applications in Food Processing, Preservation and Quality Control | Chapter 03 | Current Research in Science and Technology Vol. 3

Ultrasound is one of the emerging technologies that were developed to minimize processing, maximize quality and ensure the safety of food products. In recent years, ultrasound technology has been used as an alternative processing option to conventional thermal approaches. Although Ultrasonication methods have been used for years in research and diagnostics, major advances have been made in the last decade. The applications for which high power ultrasound can be used range from existing processes that are enhanced by the retrofitting of high power ultrasonic technology, to the development of processes up to now not possible with conventional energy sources. The present paper reviews the generation, principle mechanism, properties, process parameters, applications, merits and demerits and future trends of the ultrasound technology in the food processing.
