Quantitative determination of volatile compounds using TD-GC-MS and isotope standard addition for application to the heat treatment of food

For many foods that undergo thermal treatment, the generation of numerous process-induced compounds has strong implications for food quality and safety. Today, increasing attention is payed to the generation and occurrence of particular classes of newly formed compounds in processed foods for their potential health implication. It is therefore of the utmost importance to monitor the process with fit-for-purpose methods that are appropriate for use in quality control or in research and innovation. Since many quality-related compounds are volatile, there is a need for robust methods that can quantify a broad range of volatile markers and are applicable to on-line monitoring. To meet this need, an original and reliable method based on thermal desorption has been developed for the quantification of volatile compounds sampled on-line by sorbent tubes. For the first time, this method combines in-tube calibration and deuterated standard addition. Ten volatile compounds that are likely to form during heat processing of food (i.e. baking of cereal products), were chosen as target analytes for their relevance to food quality and their different physicochemical properties: 3-methylbutanal, pyrazine, 2-methylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, acetic acid, furfural, 5-methylfurfural, furfuryl alcohol and 5-hydroxymethylfurfural. The key steps in the analytical procedure were optimized and carefully characterized in terms of recovery, repeatability and reliability. The TD-GC-MS method displayed good linearity over extended ranges for all compounds (R-2: 0.9950 to 0.8880) with low limits of quantification (LOQs) ranging from 0.0141 to 11.5 ng. The matrix effect was negligible for most compounds, except for 5-hydroxymethylfurfural (21.5%), the most polar and least volatile compound. The method was applied to determining process-induced compounds generated during the baking of a model cake and sampled from baking vapors at three different times during the heat treatment. Of all the compounds extracted, the target analytes exhibited concentrations spread over very broad ranges. This highly sensitive method could therefore be used for the early quantification of relevant markers during the processing of food matrices, for quality or mitigation purposes. Quantitative TD-GC-MS with in-tube calibration and isotope standard addition is particularly well-suited for applications where an accurate determination is required of both trace level and major volatile compounds over time. This method may therefore be relevant for monitoring either industrial or domestic food processes (e.g. baking, frying, roasting), for multi-residue analyses linked to quality and safety, or reaction kinetics for multi-response modeling. It can also be transferable to emerging non-food applications.

Volatile compounds sorption during the aging of Chinese Liquor (Baijiu) using Pottery Powder

Pottery jar is the preferred storage vessel for aging baijiu, Chinese liquor, and it could sorb liquor micro-compounds. The objective of this work was to identify the sorption of liquor micro-compounds onto pottery powder, and gained insights regarding the sorption processes and mechanism. The sorption of liquor micro-compounds onto pottery powder of different sizes was studied using different kinetic models. The results showed that the sorption capacity varied among particle size of pottery powder, which also affected equilibrium time. The sorption process could be well described by the pseudo-second-order model, and the external diffusion was the rate-limiting step. Liquor volatiles in pottery powder at equilibrium were characterized, which detected alcohols, esters, acids, and furan by gas chromatography-mass spectrometry (GC-MS). These findings demonstrated pottery could not only cause subtractive changes that occur to liquor during the aging period, but also as a vector for transferring aromas sorbed when reused.

Highly Thermal-Resistant and Biodegradable Textile Sizes from Glycols Modified Soy Proteins for Remediation of Textile Effluents

Poly(vinyl alcohol) (PVA) sizes are widely used in textile industry due to their excellent sizing properties on synthetic fibers and their blends. However, PVA contains non-biodegradable chemicals and is a major contributor to environmental pollution related to the textile industry. To overcome this problem, an environmental-benign and highly thermal-resistant yarn coating is fabricated from soy proteins, an agricultural byproduct. The soy proteins are chemically modified by glycols having varying chain lengths and number of hydroxyl groups. Compared with the physically modified soy proteins and their sized yarns, coating made from the soy proteins esterified by 1,4-butanediol show 91.38% increment in work of rupture at 120 degrees C and cotton/polyester (65/35) yarns sized by 1,4-butanediol esterified soy protein sizes have 39.91% decrease in coefficient of friction. In addition, 1,4-butanediol esterified soy sizes have a five-day biochemical oxygen demand/chemical oxygen demand of 0.476, indicating that the chemically modified soy sizes have high biodegradability in activated sludge. Successful utilization of modified soy sizes can promote large-quantity applications of soy byproducts, impelling high value addition to agricultural byproducts and sustainability of textile industry.

Active and intelligent biodegradable packaging films using food and food waste-derived bioactive compounds: A review

Background: The growing environmental concern of plastic packaging disposal has led to the innovation of biodegradable biopolymers. Consumer demand and health concern further necessitate the emergence of active and intelligent packaging system to monitor the quality of packed food. Whereas, the use of chemical dyes as an indicator in smart packaging is not suitable for food packaging because of their high toxicity and harmful effects on human health and the environment. Hence, the researchers are focused on natural pigments derived from plants and food waste as indicating substance in biodegradable packaging and also for the valorization of food waste. Scope and approach: This paper summarizes the research on the utilization of naturally derived food- and food waste-based pigments (anthocyanins, curcumin, betalains, carotenoids, chlorophyll, brazilin, quercetin, etc.) with biopolymeric matrices (starch, cellulose, chitin, gums, agar, etc.) to fabricate smart biodegradable films, for effective monitoring of spoilage and quality of meat products, seafood, milk, and others. Key Findings and Conclusions: The results show that the smart packaging material developed by the biopolymers with plant-based pigment has the potential to replace the traditional plastic packaging materials. The extracted from food and food waste act as an indicator in smart packaging and promotes the valorization of food waste. The biodegradable packaging is economical, safe, non-toxic, sensitive, and natural pigments act as a quality indicator in packaging systems. Further, these packaging films can be optimized and commercialized and to be employed as active and intelligent packaging for visual quality evaluation of fresh food products.

Genetic variation in the prebiotic carbohydrate and mineral composition of kale (Brassica oleracea L. var. acephala) adapted to an organic cropping system

Kale is a nutrient-rich leafy green that is mostly grown in conventional agricultural systems. The demand for organic kale has increased in the U.S.; however, cultivars bred for conventional production are not suited to organic production in terms of yield and nutritional quality. The objective of this study was to evaluate the genetic variation in biomass, prebiotic carbohydrates, and minerals of 18 commercial cultivars and 35 PI accessions of kale adapted to the organic system. Significant genetic variation in both prebiotic carbohydrates and minerals was noted in both kale cultivars and PI accessions. In the kale cultivars, leaf biomass ranged from 41.4-271.2 g/plant, with kale cultivar Frizzy Joe being the highest and Fizz the lowest. A single 100-g serving from these kale cultivars provides mineral micronutrients (20-314 mg K; 95-539 mg Ca; 20-67 mg Mg; 13-87 mg P; 0.4-3.1 mg Fe; 0.3-0.9 mg Zn; 0.4-1.9 mg Mn; 20-1030 mu g Cu; and 0-940 mu g Se) and prebiotic carbohydrates, including sugar alcohols (1.7-26.9 mg), simple sugars (0.03-334 mg), and raffinose and fructooligosaccharides (0-11.2 mg). Compared to the commercial cultivars, the kale accessions had higher concentrations of minerals, except for magnesium (Mg) and manganese (Mn), and prebiotic carbohydrates, except for sucrose and verbascose + kestose. In the commercial cultivars, heritability estimates for prebiotic carbohydrates and minerals were relatively low except for sugar alcohols, Mg, and zinc (Zn). In the kale accessions, heritability estimates of glucose, fructose, potassium (K), and selenium (Se) were high. Overall, significant genetic variation exists among kale commercial cultivars and germplasm for prebiotic carbohydrates and minerals, indicating the nutritional quality of kale in organic production can be further improved by germplasm selection.

Disaccharide anthocyanin delphinidin 3-O-sambubioside from Hibiscus sabdariffa L.: Candida antarctica lipase B-catalyzed fatty acid acylation and study of its color properties

Enzymatic lipophilization is an important process to extend the use of anthocyanins in lipidic media. In this work delphinidin 3-O-sambubioside (Dp3sam) isolated from Hibiscus sabdariffa L. flower was esterified with octanoic acid using Candida antarctica lipase B. The physical-chemical properties of the new lipophilic pigment were studied by UV-vis spectroscopy. Dp3sam with chloride, acetate and formate as counter ions were employed to study the lipophilization reaction. The hydrolysis of the reagent was avoided with a formate counter ion and the expected product was achieved with a noteworthy change of solubility. 1D and 2D NMR characterization of Dp3sam-C8 confirmed that the lipophilization took place at the primary alcohol of the glucoside moiety. Overall, the Dp3sam-C8 ester presents a stabilization of the quinoidal base (blue color) at neutral or moderate alkaline pH, which foresees a potential use of this pigment as a broad kind of industries on lipo-soluble formulations.

Enhanced flux and fouling resistance forward osmosis membrane based on a hydrogel/MOF hybrid selective layer

Although forward osmosis (FO) technology has been widely adopted for water treatment, it still faces great challenges, including low permeability and fouling problem. Herein, a novel forward osmosis membrane was developed with a stable, uniform and defect-free polyvinyl alcohol/polydopamine coated zeolitic imidazolate framework (PVA/PDA@ZIF-8) hybrid selective layer to simultaneously enhance its transport property and fouling resistance. The prepared FO membrane exhibits improved water flux without losing the selectivity, since the PDA@ZIF-8 provide additional preferential passageway for water transporting while hinder the diffusion of salt. The optimized membrane shows a higher water flux than pristine PVA membrane (14.2 vs. 8.7 L m(-2) h(-1) in FO mode, 24.3 vs. 14.8 L m(-2) h(-1) in PRO mode) with a reasonable selectivity considering as J(s)/J(w) value (0.44 vs. 0.4 g L-1 in FO mode, 0.38 vs. 0.33 g L-1). Moreover, the dynamic fouling experiments with organic foulants (protein and polysaccharide) indicate that the prepared membrane exhibits strong antifouling property and excellent permeation recovery ability (>95.0%) due to the optimized surface property. This study opens a new avenue for treatment wastewater by developing a forward osmosis membrane based on a hydrogel/MOF hybrid selective layer. (C) 2020 Elsevier Inc. All rights reserved.

Preventing E-cigarette use among high-risk adolescents: A trauma-informed prevention approach

Exposure to childhood trauma increases the risk of tobacco use during adolescence. Recent studies have also reported potentially increased vulnerabilities to electronic cigarette (e-cigarette) use among youth with a history of childhood trauma. While empirical evidence supporting the relationship between childhood trauma and adolescent e-cigarette use is emerging, few effective preventive interventions are available to curb e-cigarette use among adolescent victims of childhood trauma. This article reviews current evidence with respect to how childhood trauma could increase risk for nicotine dependence and e-cigarette use in adolescent populations. Furthermore, this paper describes the development, design, and implementation of Rise Above (RA), a randomized, controlled trial of a trauma-informed, e-cigarette preventive intervention. Lessons learned are also discussed, including the challenges of implementing evidence-informed prevention work within communities vulnerable to traumatic events.

Tissue-specific transcriptome recovery on withdrawal from chronic alcohol exposure in zebrafish

Alcohol consumption can lead to a wide range of systemic disorders brought about by transcriptional changes. Recent studies have documented altered behavior and physiology in zebrafish exposed to alcohol. In this work, we have identified the changes in the zebrafish transcriptome in response to chronic alcohol exposure. We have further followed the extent of transcriptional recovery upon withdrawal from alcohol and found evidence of tissue-specific responses. Our results indicate a greater extent of recovery of the brain transcriptome compared to the liver. We identify two distinct classes of genes in response to withdrawal from alcohol exposure – those that recover their pre-alcohol expression profile versus those that retain altered expression even after the fish are removed from the alcohol environment. Finally, we have examined gender-specific responses to alcohol exposure in zebrafish and find evidence for distinct alcohol tolerance levels. Upon chronic alcohol exposure, a higher percentage of genes show perturbation in expression profile in males compared to females. Female fish also recover better with more genes regaining the control expression level upon withdrawal from alcohol. Overall, our work identifies genes and pathways perturbed by exposure to alcohol, and demonstrates the extent of gender- and tissue-specific transcriptional changes associated with chronic alcoholism and withdrawal.

An efficacy trial of adaptive interventions for alcohol use disorder

Background: Adaptive interventions, sometimes referred to as stepped care, are those interventions in which the type or dosage of treatment offered to patients is tailored to baseline clinical presentation and then adjusted over time in response to patient progress or lack thereof. Currently, no adaptive brief interventions exist specifically for alcohol use disorder (AUD). Method: This study used a sequential multiple assignment randomized trial design with 160 individuals with AUD recruited both locally and nationally who had a goal to reduce or abstain from drinking. Participants received brief advice (BA) and then the study reassessed them three weeks later; the study randomized those who did not respond to BA, defined as reducing their drinking to low-risk guidelines, to two session of motivational interviewing (MI) or more BA. The study then reassessed participants at week 8. The study re-randomized non-responders to receive either MI alone or MI plus behavioral self-control therapy (BSCT), also referred to as coping skills therapy, and evaluated participants at week 13. Results: Overall, participants receiving any BSCT made the greatest reductions in drinking. Participants who received MI at week 4 and BSCT at week 8 outperformed all other groups. Conclusion: Findings reveal that prolonged treatment, more sessions, and/or a specific combination of MI and BSCT provided optimal outcomes. Future research should determine whether such an algorithm holds across heterogenous groups of individuals with AUD.
