Background

Growing global demand for meat and milk has fuelled an increase in the trade in animal products, but there is still little awareness of the magnitude and characteristics of the trade in live animals. In this study, we investigated the international trade of 12 live food-producing animal species, including poultry (‘chickens’, ‘ducks’, ‘geese’ and ‘turkeys’), ruminants (‘cattle’, ‘sheep’, ‘goats’, ‘camels’ and ‘buffalo’), pigs and ‘other’ food-producing animals (‘rabbits and hares’ and ‘horses’) as reported to the FAOStat database between 2005 and 2021.

Results

The analysis revealed that international trade in most species had increased over the study period. Chickens were numerically the most traded species with an average of 1.4 billion live chickens internationally traded annually. Live export of chickens demonstrated the greatest growth over the study period, with an estimated additional 58 million animals traded each year. Intercontinental trade was also substantial, contributing to 10% or more of the international trade in eight of the 12 species. Many countries were also bidirectional traders for multiple species. The Netherlands, Germany and Poland were among both the highest importers and highest exporters for multiple species between 2019 and 2021.

Conclusion

This study provides valuable insight on the scale and trends in the international trade in livestock to inform regulations and practices that might be needed to mitigate potential threats associated with livestock movements, including disease emergence and spread, poor animal welfare, antimicrobial resistance and environmental degradation, while supporting demands and need for livestock-based foods.

Background

Titanium dioxide (TiO2) has been widely used in food products, including gums, candies and in fortified salt as a white coloring agent of iron premixes. TiO2 (E171) was banned by the European Food Safety Authority in 2021, with potential carcinogenicity concerns. This study assesses the feasibility of using inorganic alternatives to replace TiO2 in ferrous fumarate-based iron premixes for salt fortification for treatment of iron and iodine deficiencies.

Results

Varying levels of alternatives were utilized: calcium carbonate, magnesium carbonate, zinc oxide, calcium sulfate, and commercial formulations Opadry®, and Nutrafinish®. Adhesives included HPMC and gum Arabic with soy stearin as an overcoat moisture barrier. Preliminary results for MgCO3 premixes had poor adhesion, leading to exposed iron, which will be addressed in further studies. ZnO, Opadry, CaCO3 and CaSO4 premixes resembled TiO2 premixes in terms of coverage and color, especially CaSO4, attributed to calcium sulfate's small particle size resulting in high surface area for coverage. Premixes stored in iodized salt at 25, 35, 45°C and elevated humidity, for 9-month stability studies retained over 70% iodine, confirming successful encapsulation.

Conclusions

CaSO4, CaCO3 and ZnO premixes were successful in terms of appearance and stability of fortificants over 9-month storage. The levels of calcium in fortified salt were lower than that which would impede iron absorption. Therefore, these calcium and zinc alternatives would be suitable alternatives to titanium dioxide premix for use in fortified salts. Premixes will be scaled-up for cost-effective salt fortification to address micronutrient deficiencies in low middle income countries.

Background

Many reports from the UK government and other organisations highlight a need for a plant aware workforce, and some enumerate specific areas of plant science where there is a skills shortage. We have undertaken a systematic analysis of the content of degree programmes that advertise as teaching plant biology to determine if the UK Higher Education (HE) sector is delivering the graduates required to meet the skills gaps reported.

Results

Our data reveals a highly mixed picture of delivery from 1- to 4-year courses, modules ranging from 10 to 40 credits, and Higher Education Institutions (HEIs) providing variable information on their websites. Our analysis shows that on average (irrespective of credit) a module covers three subject areas. Most courses have little plant content and it is generally taught with other subjects on a module. The most substantial plant-specific subject teaching is delivered on 18 courses we have identified as Plant Science courses.

Conclusion

Overall, the UK HE sector is not delivering graduates with the skill set outlined in numerous reports as required to enable food production in a changing climate. Any prospective student (or employer) will find it virtually impossible to determine which degree will deliver the skills they need as there is no plant curriculum offered across the board, and specific information is hidden within module descriptors on websites. If the skills outlined as being essential for the economy and society are truly important, then a new approach is required.

Background

Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic-medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho-agronomical traits, phenolic compounds and antioxidant activity in the aboveground biomass. Emphasis gave on the post-harvest determination of seed yield and essential oil's (EO's) profile for each genotype.

Results

Multivariate data analysis on both morpho-agronomical descriptors and EO's components demonstrated clear distinction of Greek fennel accessions (groups I and III) from commercial varieties (group II). Accessions of groups I and III were ranked with intermediate values of height, foliage density, leaf length, green color intensity and primary canopy diameter. In addition, fennel accessions differentiated in their EO's yield (ranged from 2.2% to 7.8%), although they exhibited similar qualitative profile. The main EO's compound of group I was trans-anethole, estragole and fenchone for group III, while commercial varieties characterized by high concentration in trans-anethole and fenchone. Variations among genotypes were also demonstrated in the content of total phenolics (7.0–11.6 mg g−1 on dry weight basis, dw) and flavonoids (5.9–12.4 mg g−1 dw), while the antioxidant activity determined by ABTS test, varied from 9.0 to 16.2 mg Trolox equivalents g−1 dw.

Conclusion

The observed variability in morpho-agronomical descriptors and phytochemical profile among fennel genotypes recorded for the first time the potential of Greek native genetic material. The data of this research provides useful information for direct future uses in pharmaceutical industry and for applications in plant breeding programs, aiming to produce new type of fennel varieties.

Separation and quantification of mycotoxins in floral tissue of hemp (Cannabis sativa) infected with Fusarium graminearum
Pub Date : 2025-01-27 DOI: 10.1002/jsf2.235

Background

The fungal pathogen Fusarium graminearum produces mycotoxins when it infects grains. This pathogen also infects hemp (Cannabis sativa L. containing less than 0.3% tetrahydrocannabinol or THC). The presence of trichothecene mycotoxins like deoxynivalenol (DON) has not been reported in floral tissue of hemp infected with F. graminearum. The object of this study was to develop a method to extract three trichothecene mycotoxins—DON, 3-acetyldeoxynivalenol (3-ADON), and 15-acetyldeoxynivalenol (15-ADON)—from hemp floral tissue, and to quantify the mycotoxins by high-performance liquid chromatography (HPLC) with ultraviolet detection.

Results

Standards of nivalenol (NIV), DON-3-glucoside (D3G), DON, 3-ADON, and 15-ADON were separated from each other and from standards of several cannabinoids. Standard curves were linear (R-squared values >0.99). Recoveries from hemp spiked with 36 μg/g mycotoxins were 86%–90% for DON, 75%–77% for 15-ADON, and 86%–101% for 3-ADON. In extracts of hemp inflorescences infected with different strains of F. graminearum (15-ADON chemotypes), DON was detected in one sample. Other samples contained 15-ADON but no detectable DON, or neither mycotoxin in detectable amounts.

Conclusion

Mycotoxins were separated from cannabinoids. DON was also separated from matrix components, and 15-ADON and 3-ADON were partially separated from matrix components. The presence of DON in hemp may depend on fungal strain or stage of disease development, as well as the sensitivity of the method. The current method could quantify DON and 15-ADON at about 3 μg/g in hemp floral tissue, and 3-ADON at about 6 μg/g.

Sensory and chemical profiles of bread derived from the novel semi- and wholegrain flour enrichment of Triticum aestivum L. old genotypes with organic stinging nettle
Pub Date : 2025-01-17 DOI: 10.1002/jsf2.236

Background

Bread made from refined Triticum aestivum L. flour, a staple food in large parts of the world, is considered a nutrient security risk. Strategies used to enhance the nutritional and functional properties of wheat-derived food products include the use of semi- or wholegrain flour, old genotypes, and enrichment through fortification. Limited studies exist on biofortifying staples with neglected and underutilized species. The innovative approach of the present study was to combine all aforementioned strategies, which involved the enrichment of semi-wholegrain and wholegrain bakery products derived from an organically cultivated mix of five T. aestivum soft wheat landraces (Andriolo and Gentil Rosso) and old varieties (Frassineto, Inallettabile, and Verna) with Urtica dioica L. (stinging nettle [SN]), also cultivated under sustainable management.

Results

The organoleptic assessment showed that the enrichment of semi-wholegrain and wholegrain traditional Italian bakery products with 3% SN was appreciated for the first time by free tasters representing the “health conscious” sector of the population. Moreover, the functional component content (fiber, polyphenols, flavonoids, and antiradical activity) significantly exceeded that reported previously for refined flour.

Conclusion

Consumer acceptance of SN-enriched wholegrain bakery products shows potential to meet the increased demand for fortified products, with the raw ingredients suited for cultivation under environmentally sustainable management practices.

Background

Most pure maple syrup produced in North America is produced from the sap of sugar maple trees (Acer saccharum). Interest is growing to utilize other maple species in different regions of North America outside the native range of sugar maple. This research assesses a maple syrup produced in one of these regions, bigleaf maple (Acer macrophyllum) from the Pacific Northwest. Two blind-coded consumer-sensory evaluations, which took place in May 2022 and 2023, were conducted with 411 participants to assess overall sensory hedonics and descriptors, quality ratings, purchase intent, and perceptions of the syrup category with 13 unique samples of bigleaf maple, sugar maple (A. saccharum), and imitation maple syrup.

Results

Two bigleaf maple syrups were rated highest in overall liking. Of the syrups tested, several of the bigleaf maple syrups were rated as having the most complex flavor profile. When consumers were segmented on overall liking, flavor complexity intensity was positively correlated (p < 0.05) with perceived quality, purchase intent, and overall liking for the larger cluster of consumers (n = 154), though there seems to be an optimum level over which the syrup can then be penalized for being too complex. A correspondence analysis (CA) showed the syrups that were most well-liked exhibited qualities “maple,” “sweet,” “caramel,” “nutty,” “honey,” “vanilla,” and “fragrant.”

Conclusion

This research demonstrates that quality bigleaf maple syrup is a well-liked product of interest and has high potential for commercial success.

Identification of pollen types of beekeeping interest by non-targeted mass spectrometry 通过非目标质谱法识别养蜂业感兴趣的花粉类型
Pub Date : 2025-01-13 DOI: 10.1002/jsf2.228

Background

The identification of pollen is important in the field of beekeeping for the determination of the botanical origin of bee products and investigations of bee diet. Until now, it has been performed by melissopalynology, the microscopic examination of pollen grains. However, this technique has some limitations, such as the necessity of experienced analysts and identification restricted to the family level for some pollen types. Although many techniques have been proposed as alternatives or complements to melissopalynology and omics techniques have been explored to gather information on the botanical origin of honey, no study has yet been conducted on a large set of pollen types.

Results

The study dataset consisted of 34 different pollen types of pellets collected by honeybees in Switzerland and analyzed in multiple biological replications, leading to 150 observations. The pollen samples were analyzed after tryptic digestion using a non-targeted mass spectrometry-based method. Liquid chromatography coupled with mass spectrometry (LC–MS) was employed to identify pollen, and melissopalynology was used as a reference method for the identification. We built an OPLS-DA prediction model for the 34 pollen types. The model clearly identified new samples in their membership group (Acer sp., n = 10) and a new pollen type at the species-specific level for Quercus sp. Less predictable results were achieved for Composita H and pollen collected directly from the plant.

Conclusion

The use of a non-targeted mass spectrometry-based method and chemometrics resulted in a promising tool for pollen identification as a replacement/supplement method to traditional melissopalynology.

背景 在养蜂领域,花粉的鉴定对于确定蜂产品的植物来源和调查蜜蜂的食性非常重要。迄今为止,一直是通过花粉显微镜检查花粉粒来进行鉴定。不过,这种技术也有一些局限性,例如需要经验丰富的分析人员,而且对某些花粉类型的鉴定仅限于科一级。尽管已经提出了许多技术作为花粉学的替代或补充,并探索了 omics 技术来收集有关蜂蜜植物来源的信息,但还没有对大量花粉类型进行过研究。 研究结果 研究数据集包括蜜蜂在瑞士采集的 34 种不同花粉类型的颗粒花粉,并对其进行了多次生物重复分析,从而获得了 150 个观察结果。花粉样本经过胰蛋白酶消化后,采用非靶向质谱方法进行分析。采用液相色谱-质谱法(LC-MS)鉴定花粉,并将花粉学作为鉴定的参考方法。我们为 34 种花粉类型建立了 OPLS-DA 预测模型。该模型在其成员组(Acer sp.,n = 10)中明确识别出了新样本,并在物种特异性水平上为 Quercus sp. 结论 使用基于非靶向质谱的方法和化学计量学,为花粉鉴定提供了一种很有前途的工具,可作为传统花粉学的替代/补充方法。

Prevention of inflammation and oxidative stress by new ingredients based on high (poly)phenols winery by-products
Pub Date : 2025-01-12 DOI: 10.1002/jsf2.224

Background

New circular economy policies for producing high-value ingredients and co-products, rich in bioactive phytochemicals, have boosted valorising agro-food residues, as sources of powerful functional compounds. In this context, (poly)phenols of winemaking by-products have been associated with anti-inflammatory and oxidative stress (OS) prevention. Nevertheless, this application needs stabilisation of such materials by fine-tuning processing conditions, in a fashion compatible with the industrial capacities, to minimise the impact on the phytochemical profile. To fill these gaps, the present study uncovered the capacity of high (poly)phenol ingredients from winery by-products (obtained by an oven a dehydration system), to modulate inflammatory and OS markers and mediators associated with intestinal inflammation.

Results

The results confirmed minimal changes in the winery residues' (poly)phenolic burden. The ingredients obtained provided (poly)phenolic pools that reduced the secretion of inflammatory markers, namely nitrates/nitrites, IL-6, IL-8 and TNF-α by up to 66.8%, 20.1%, 95.4% and 78.3%, respectively. Even more, they also prevented ROS increase, preserving the molecular machinery of cells against OS (glutathione, catalase, superoxide dismutase and glutathione peroxidase) in a significant manner. The correlation analyses allowed identifying proanthocyanidin dimer (B-type) digallate, galloyl hexoside, ferulic acid hexoside, cyanidin 3-O-p-coumaroylglucoside, as the main anti-inflammatory compounds; and galloyl hexoside, ferulic acid hexoside, kaempferol glucoside and cyanidin 3-O-p-coumaroylglucoside, as the most powerful antioxidant molecules.

Conclusion

These results support the interest in winery by-products processed according to industrial procedures as sources of compounds with anti-inflammatory and OS prevention traits.
