Essential oils and their bioactive components are promising alternatives to synthetic preservatives. To overcome challenges associated with EOs, nanotechnology has emerged as a novel technology in the food industries. Nanoencapsulation may boost the preservative potential of different essential oils by improving their solubility, stability, and targeted sustainable release. Nanoencapsulation of EOs is therefore currently being practiced to improve the stability and bioactivity of natural products. The present review has dealt extensively with the application of EOs and their nanoformulated products encapsulated in suitable polymeric matrices, so as to recommend them as novel green preservatives against foodborne molds and mycotoxin-induced deterioration of stored food commodities. © 2021 Society of Chemical Industry. Newly developed yellow biofortified cassava has been adjudged as a cost-effective solution to vitamin A deficiency in low- and middle-income countries with high cassava intake such as Nigeria. In this study, yellow cassava was developed into a novel pasta enriched with amaranth vegetable and tested among consumers. Attitudes, perception, motives for consumption and perceived barriers were ascertained using focus group discussions and randomised face-to-face interviews, while liking, preference and ranking of the novel food were established through consumer sensory perception. Willingness to consume the new food, low food neophobia (32%), a health-driven consumption pattern, as well as an appreciable acceptance for the developed pasta, was established among the consumers. Ugwu (Telfairia occidentalis) was found to be the most preferred leafy vegetable. The yellow cassava pasta was ranked better than the conventional white cassava. This study shows new avenues to valorise yellow cassava by which nutrition security can be improved in low- and middle-income countries of Africa. © 2021 The Authors.

Cold shock proteins (CSPs) play an important role in bacterial cold adaptation. In this study, the CSP genes were obtained from the genome of P. fluorescens PF08 by search the conserved domain of CSPs through HMMER software, and their physicochemical property, structure and function were analyzed by bioinformatics. A total of five typical CSPs are identified in P. fluorescens PF08 genome (PfCSPs). The results showed that the five PfCSPs are all small hydrophilic acidic proteins with molecular weight around 7.4 kDa. They are located in the cytoplasm and are non-secretory and non-transmembrane proteins. Multiple sequence alignment analysis indicated the CSPs were highly conserved between different species, especially in DNA-binding sites and RNA-binding motifs that can bind to single-stranded DNA and RNA. The five PfCSPs were clustered together with CspD from Escherichia coli and Salmonella typhimurium , which suggested that a close homology and high functional similarity among the five PfCSPs and CspD. The secondary and tertiary structures of the PfCSPs are accordance with the characteristics of the CSPs family and ligand binding sites with higher likelihood were found in PfCSPs. The five PfCSPs were predicted to interact with some of the same proteins that involved in virulence, stress responses (including low temperature), cell growth, ribosome assembly and RNA degradation. The results provides references for further elucidation of the function of CSPs in the process of low temperature adaptation of P. fluorescens . Smoking rates are alarmingly high among young people experiencing homelessness (YEH), yet there are no evidence-based cessation programs for this population. This paper presents results from a pilot evaluation of a text messaging-based smoking cessation treatment, as an adjunct to brief group cessation counseling, to improve abstinence rates among 18-25 year old smokers experiencing homelessness. The goal of this study was to estimate effect sizes for a larger trial and it was not powered to detect group differences. YEH smokers who had a working cell phone with them at recruitment were randomized to receive a group counseling session, nicotine patches, and written material on quitting (n=37) or a similar program that also included a 6-week automated text messaging intervention (TMI) to provide ongoing support for quitting (n=40). Smoking outcomes were evaluated through a 90-day follow-up. 7-day point prevalence abstinence at 90-day follow-up was higher in the TMI condition than standard condition (17.5cy of this approach as an adjunct to standard care (brief group counseling and pharmacotherapy) for smoking cessation among young people experiencing homelessness.This is the first study to evaluate the feasibility of using a text messaging-based intervention (TMI) for behavior change with 18-25 year olds experiencing homelessness, and more specifically, the first to test a TMI to provide ongoing support for smoking cessation. Small to medium effect sizes for the TMI are promising in terms of implementing a TMI using participants' own cell phones, as well as the efficacy of this approach as an adjunct to standard care (brief group counseling and pharmacotherapy) for smoking cessation among young people experiencing homelessness.Intervention technologies for inactivating Salmonella in whole chia seeds are currently limited. The determination of the thermal inactivation kinetics of Salmonella o n chia seeds and selection of an appropriate nonpathogenic surrogate will provide a knowledge foundation for selecting and optimizing thermal pasteurization processes for chia seeds. In this study, chia seed samples from three separate production lots were inoculated with a five strain Salmonella cocktail or Enterococcus faecium NRRL-B2354 and equilibrated to 0.53 aw at room temperature (25 °C). After equilibration for at least three days, the inoculated seeds were subjected to isothermal treatments at 80, 85, or 90 °C. click here Samples were taken out at six timepoints and enumerated for survivors. Initial dilution of whole chia seeds was performed in a filter bag at a 130 ratio after it was shown to have similar recovery to grinding the seeds. Survivor data were fitted to consolidated models consisting of a primary model (log-linear or Weibull) and one secondary model (Bigelow).
