Abstract French physical chemist, Hervé This, first proposed Note by Note (NbN) cooking in 1994. It is an application of molecular gastronomy and involves the use of compounds, either pure or in mixtures, rather than traditional food ingredients to make dishes. A review of international activities, relating to NbN cooking and cuisine, reveals that it has the potential to contribute to the creation of bespoke foods and drinks, e.g., by using ingredients which are sustainable and which provide nutritional value. However the ‘food neophobia’ of some consumers needs to be overcome to ensure its success. In light of these findings, it was decided to explore if and how the factors of food neophobia, sustainability and nourishment influenced students when they were developing their NbN dishes/drinks for their module assignment in TU Dublin. One hundred and five students at TU Dublin have, since 2013, completed NbN assignments and their corresponding reports which provide details of the development of their dishes/drinks. Eighty-seven of these were available for analysis. It was found that the majority of the students (62%) were inspired by traditional foods to create bespoke NbN dishes/drinks, helping to address the ‘food neophobia’ of some consumers. The development of one of these dishes and one of these drinks is discussed. This information would be beneficial for others who will be developing NbN dishes/drinks.

This paper attempts to provide and insight into the modernization of Malay food ingredients within Malay communities. Its approach is sociological, using qualitative method of interview and observation, inquiring into the usage of modern food ingredients in the preparation of Malay dishes. Focusing on a small group of consumers in Puncak Alam, Selangor, the findings indicate that the motivation behind choosing modern food ingredients is to save cooking preparation time while improving nutrient intakes.© 2016.

We assessed the effect of chitosan on Helicobacter pylori (HPY) in vitro to provide an experimental basis for the clinical application of chitosan in the treatment of gastric diseases. Here, the method of hole drilling was used to detect the bacteriostatic effect of different concentrations and pH values of chitosan on the standard bacterial strain Sydney strain I (SSI) and two strains of HPY isolated from patients. The bacteriostatic test was used to explore the effect of different molecular weights of chitosan and metal ions on the antibacterial effect of chitosan. The effect of chitosan showed no significant difference among three HPY strains (p < 0.05); moreover, in the range of pH 5.5–8.5, the antibacterial effect of chitosan increased with decrease in pH value (p < 0.01). A significant difference in the antibacterial effect of chitosan was observed at different concentrations (p < 0.01), reaching a peak at 40 g/mL. The molecular weight of chitosan was within 400 kb. With increasing molecular weight, the antibacterial activity of chitosan increased initially and then decreased. The molecular weight of 0.200 kb demonstrated the strongest anti-HPY effect, with the antibacterial effect observed for up to 134 h. Metal ions such as NaCl and MgCl2 affected the anti-HPY effect of chitosan; with increasing concentration, the antibacterial percentage decreased.

Helicobacterpylori is one of the most prevalent pathogens colonizing 50% of the world’s population and causing gastritis and gastric cancer. Even with triple and quadruple antibiotic therapies, H. pylori shows increased prevalence of resistance to conventional antibiotics and treatment failure. Due to their pore-forming activity, antimicrobial peptides (AMP) are considered as a good alternative to conventional antibiotics, particularly in the case of resistant bacteria. In this study, temporin-SHa (a frog AMP) and its analogs obtained by Gly to Ala substitutions were tested against H. pylori. Results showed differences in the antibacterial activity and toxicity of the peptides in relation to the number and position of D-Ala substitution. Temporin-SHa and its analog NST1 were identified as the best molecules, both peptides being active on clinical resistant strains, killing 90–100% of bacteria in less than 1 h and showing low to no toxicity against human gastric cells and tissue. Importantly, the presence of gastric mucins did not prevent the antibacterial effect of temporin-SHa and NST1, NST1 being in addition resistant to pepsin. Taken together, our results demonstrated that temporin-SHa and its analog NST1 could be considered as potential candidates to treat H. pylori, particularly in the case of resistant strains.

AbstractJangkanghwan (JKH) is a Korean traditional food that is a mixture of food ingredients and traditional Korean medicine ingredients, and it has been observed to produce satisfactory anti-inflammatory, antioxidant, and antibacterial effects. In the current study, JKH was administered by gavage to BALB/C mice with lipopolysaccharide (LPS)-induced colonic epithelial dysfunction, and mouse body weight and food intake were recorded. Indexes such as colonic paracellular permeability, serum inflammatory cytokines, and bacterial translocation were used to comprehensively evaluate the regulatory effect of JKH on mouse colonic epithelial function, and qPCR and Western blot were also used to analyze the expression of tight junction (TJ)-related genes, such as occludin, claudin, zonula occludens (ZOs) proteins, and junction adhesion molecules (JAM) in the colonic epithelial tissue. The experimental results indicated that JKH relieved the edema of the liver, spleen, and mesenteric lymph node tissues, and reduced the loss of appetite and diarrhea caused by LPS injection in mice. It increased the amount of mice food intake from 3.7 g/day in the LPS group to 4.7 g per day; the water content in the feces of mice in the JKH group was 13.86% less than that in the LPS group. JKH reduced the inflammatory response in mice caused by LPS, protected the integrity of the colon, the permeability of fluorescent macromolecules was one-fourth of the LPS group, and enhanced the mRNA and protein expression of TJ-related proteins in colon tissue. Our findings highlight that JKH has benefits in intestinal health and relieving systemic inflammation, relevant aspects of its use as a functional food.
