Assessment of allyl isothiocyanate as a fumigant to avoid mycotoxin production during corn storage

2016

The occurrence of fungi and mycotoxins in foods modify sensorial properties and represents a health risk for consumers, and the use of natural antimicrobials may be an alternative to reduce this problem. The objective of this study was evaluate the potential of allyl isothiocyanate (AITC) in inhibit the production of mycotoxins in corn kernels by Aspergillus parasticus, Fusarium tricinctum, Fusarium verticillioides, Alternaria alternata and Gibberela zeae. Kernels were treated with gaseous AITC at 50, 100 or 500 μL/L during 48 h in hermetic flasks. Then, flasks were opened for 24 h and 100 g of corn were inoculated with 105 conidia/g of either fungal species. Flasks were kept at 23 °…

Nitrogen sources in the must are important for yeast metabolism, growth, and performance, and wine volatile compounds profile. Yeast assimilable nitrogen (YAN) deficiencies in grape must are one of the main causes of stuck and sluggish fermentation. The nitrogen requirement of Saccharomyces cerevisiae metabolism has been described in detail. However, the YAN preferences of non-Saccharomyces yeasts remain unknown despite their increasingly widespread use in winemaking. Furthermore, the impact of nitrogen consumption by non-Saccharomyces yeasts on YAN availability, alcoholic performance and volatile compounds production by S. cerevisiae in sequential fermentation has been little studied. With…

Strontium isotopes in biogenic apatite, especially enamel, are widely employed to determine provenance and track migration in palaeontology and archaeology. Body tissues record the 87Sr/86Sr of bioavailable Sr of ingested food and water. To identify non-local individuals, knowledge of the 87Sr/86Sr of a non-migratory population is required. However, varying factors such as tissue turnover rates, feeding selectivity, Sr content, digestibility of food, and the ingestion of mineral dust can influence body tissue 87Sr/86Sr. To evaluate the Sr contribution of diet and water to mammalian hard tissues 87Sr/86Sr, controlled feeding studies are necessary. Here we present 87Sr/86Sr from controlled fe…

The many faces of human sociality: uncovering the distribution and stability of social preferences

2018

There is vast heterogeneity in the human willingness to weigh others' interests in decision making. This heterogeneity concerns the motivational intricacies as well as the strength of other-regarding behaviors, and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations. We tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome-based and reciprocity-based social preferences. We find that non-selfish preferences are the rule rather than the exception. Neither at the level of …

Accentuating the Interrelation between Consumer Intention and Healthy Packaged Food Selection during COVID-19: A Case Study of Pakistan

2021

This study contemplates the factors that influence consumer intention, before and during the eruption of COVID-19, for the selection of healthy packaged food in Pakistan. The extant studies have identified two distinct attitudes of consumers about food label information: one is its usefulness and the second elucidates the avoidance. Hence forth, the current study contributes to the extant literature while signifying both reasons which motivate consumers to read food labels and reasons which discourage consumers from consult food labels at the point of purchase. Moreover, the impact of subjective norms and self-efficacy for healthy packaged food intentions has also been examined for both bef…

Starppriekšmetu un savstarpējās sadarbības projekti angļu valodas rakstīšanas prasmju pilnveidei 9.klasē

2022

Sākoties jaunajam mācību gadam, pakāpeniska jaunā mācību satura ieviešana ir kļuvusi par vienu no svarīgākajām sarunu tēmām skolās. Projekta Skola2030 mērķis bija attīstīt skolēniem vairākas svarīgas 21. gadsimta prasmes, kā arī koncentrēt uzmanību uz mācību priekšmetu padziļinātu izpratni un padziļināti izprast mācību vielu nevis sadrumstaloti. 2020./2021. mācību gadu skolēni pavadīja attālināti, un tas sagādāja grūtības attīstīt rakstīšanas prasmes angļu valodas mācību stundās. Tāpēc tika izvēlēta daudznozaru un savstarpējās sadarbības pieeja, lai attīstītu visas nepieciešamās prasmes. Tika veikts gadījuma pētījums, kurā piedalījās 14 skolēni no 9. klases, 7 dažādu mācību priekšmetu skolo…
