The main objectives of our work were to produce new nanostructured lipid carriers (NLCs) from interesterified and simple lipid phases and to study the influence of lipid composition on the physical characteristics and stability of NLCs. We used conventional oils and fats already used in lipid-based foods, in addition to soy lecithin as a natural emulsifier. The NLCs were formulated using as lipid phase, simple and interesterified blends composed of soybean oil as liquid lipid and fully hydrogenated oils from palm, soybean, microalgae, and crambe as solid lipids. NLCs were produced using high-pressure homogenization. NLCs were influenced by chemical interesterification and by the composition of the solid lipid used, mainly in relation to the fatty acid chain size. NLC formulations developed with a simple lipid phase were 256-323 nm (d32) in size, with zeta potential values ranging from -36.93 to -42.87 mV after 60 days of storage. NLCs developed with the interesterified lipid phase were 250-288 nm (d32) in size, with zeta potential values ranging from -40.17 to -44.20 mV after 60 days of storage. NLCs produced with saturated fatty acids with larger chain sizes showed larger particle sizes but showed less variation in this parameter over storage. Interesterification reduced the melting temperature of NLCs, indicating decreased crystallinity and a less organized structure. KU-60019 Moreover, interesterification favored crystals in the β‘ form, which is a positive characteristic for incorporating bioactive compounds. Thus, the systems developed in this study are innovative, mainly in terms of the composition of the NLCs, and have good potential for food applications.The level of contamination of food produced in commercial restaurants is directly related to the quality of training provided to kitchen workers. Leaders, who are responsible for food safety training, face the obstacle of food safety practices (FSP) daily application. However, noncompliance with FSP permeates both the problematization about training, and other influential elements in the kitchen environments. This study aims to characterize the current training in FSP, discuss the reasons that lead to noncompliance with FSP by kitchen workers in commercial restaurants, and indicate possible ways for improvements in food safety in this field. Twenty-one professionals‘ interviews were analyzed according to Bardin’s content analysis method. The analyzes were carried out from three groups legislators/entities, teachers and agents of practice (all professionals directly involved in daily food preparation). Sociological concepts described by Pierre Bourdieu and Michel Foucault grounded the exploration of the social aspects. The current training is characterized by the ineffectiveness of the application methods and content offered, the type of approach used by the nutritionist or leader responsible for its effectiveness, and leadership assumptions about the knowledge of FSP by kitchen workers. Forty-seven reasons for noncompliance with sanitary regulations were identified. Unprepared leadership and the perception of an absence of constant surveillance of kitchen workers stood out as the first and second most cited reasons. The multiplicity of factors indicates this theme’s complexity and shows that every person involved in commercial restaurants needs to be responsible for FSP. Addressing the challenges using the possible pathways of food safety could potentially improve compliance withfood safety practices.Adhesiveness is one of the important sensory properties of noodles. A better understanding of the molecular basis of the sensory property would allow for a more reasonable selection of wheat ingredients. In this study, the adhesiveness of cooked noodles made from reconstituted wheat flour was evaluated using a texture profile analyzer. The rheological properties of dissolved solids from the noodle surface were measured. The composition and structure of leachate, as well as multi-structure of native starch were analyzed. The correlation analysis showed that adhesiveness positively correlates with the loss modulus parameters [log K‘ (consistency coefficient) and Ea (activation energy)]. Increased content of leached starch can ascend the rheological parameters (log K‘ and Ea). In addition, more short amylose chains with 100-500 degree of polymerization (DP) in leached starch also induced the increase of log K‘ (p less then 0.01) and Ea (p less then 0.01). The fraction of short amylose chains in leached starch was negatively correlated with the content of long amylopectin chains ranged from 37 to 100 DP in native starch (p less then 0.05), as well as the median diameter of particles (p less then 0.01). Multi-level structures of native starch granules largely determine the composition and molecular structure of noodle leachate, consequently contributing to surface rheological properties. It is thus proposed that wheat starch with more long amylopectin chains and large granules could be used to reduce noodle adhesiveness. Moreover, the rheological approach using noodle surface materials proposed here is useful to predict the noodle adhesiveness as an important sensory characteristic.This paper presents complete HPLC profiles and MS spectrometric data of bioactive compounds from four cultivars of red lettuce produced in winter and summer and their antioxidant capacity. The experiment was carried out in a greenhouse, where red curly lettuce was cultivated Mila, Maira, Carmin and Scarlet. The cultivar and season have not influenced the qualitative profile of carotenoids (CAR) and phenolic compounds (PC) of red lettuce. Instead, the season influenced the concentration of these components in all cultivars. The levels of phenolic compounds were significantly higher in winter, while the levels of carotenoids were higher in summer. Ten anthocyanins were identified (cyanidins and delphinidins). The main carotenoid found was the all-trans-β-carotene (45-48%), followed by lutein (13-20%) and zeaxanthin (11-15%). Major phenolic compounds include 5-caffeoylquinic acid, rutin and amentoflavone. Red lettuce cultivars have their main bioactive compounds described and compared within the variety and within the growing season. Different season and different lettuce cultivars may differ in the content of their bioactive compounds and in their antioxidant capacity.Lactococcus lactis subsp. lactis (L. lactis subsp. lactis) is commonly found in naturally fermented dairy products (NFDPs). This subspecies is of high economic value due to its wide application in dairy industry. However, the genetic background and evolutionary history of L. lactis subsp. lactis are still poorly understood, analysis of its genetic background and functional genome will lay a genetic foundation for its application. This study analyzed the whole genomes of 227 novel L. lactis subsp. lactis isolated from NFDPs and investigated the genetic history of this subspecies from a population genetic perspective. These strains were classified into four phylogenetically distinct groups, which were likely derived from only a few wild ancestors through three divergence events, resulting in genetic and phenotypic divergence. Functional genomic analysis found that the divergence events caused strong lineage-specific selection for carbohydrate utilization and lactic acid production genes. Moreover, the time of the divergence coincided with mass migration of nomads due to climate change and decrease in average annual temperature, suggesting that these drastic environmental changes might be evolutionary drivers of the divergence. Genome-wide association analysis results showed that the single nucleic acid polymorphic loci we associated with pepF and CoiA genes were significantly correlated with fermentation capability, and based on this, a rapid screening model for potential starter strains was constructed. Our findings shed light on the evolutionary history and genomic diversity of NFDP-originated L. lactis subsp. lactis, and provide a new insight for screening strains with excellent characteristics.Antibiotic residue, an emerging contaminant, has been an increasing concern worldwide in vegetables. However, the focus is still limited to its accumulation in vegetables and its adverse health effect on humans, with little mention of its impact on the vegetable process. Fermentation is an important method of the vegetable process. Tetracycline (TC) is the most widely used antibiotic, and its residue is often higher than other antibiotics in ginger. Therefore, current research was to characterize how the TC residue affected the lacticacidbacterial (LAB) communities and metabolites during the salted fermentation of ginger. The TC residue, organic acids, volatile compounds and LABs were analyzed during the fermentation, and the correlations between the LABs and compounds were also revealed. The results suggested that the hetero-lactic fermentation did not happen under the TC residue although the TC residue decreased from 4 mg/kg to 2.56 mg/kg in salt brine of ginger fermentation. Meanwhile, TC residue affected the occurrence, propagation and succession of LABs. The LAB biomarkers shifted to Lab. parafarraginis, Lab. buchneri and Lab. kisonensis under TC residue. Responded to LAB communities, the organic acids and volatile compounds were also markedly changed under the TC residue. And the important volatile compound variables shifted to citronellol, allylsenevol, geranyl acetate, vinylstearylether, isothiocyanic acid phenethyl, 3-octanol, geraniol, bingpian, citral and camphor. The transformation of LAB biomarkers induced by TC residue was the main cause of the change of important volatile compound variables, but interestingly, not all of them had significant positive or negative correlations. These results indicated that the antibiotic residue has an adverse ecological effect on the vegetable fermentation process.Therefore, the antibiotic residue should be listed as a quality control index in fermented vegetable raw materials.In the present study, foodomics approach was employed to investigate changes in the metabolism from the volatile terpenoids profile of mint(Mentha × gracillis Sole)from conventional, organic and permaculture (a type of agroecological agriculture system) farms using headspace solid-phase microextraction (HS-SPME) associated to gas chromatography coupled to mass spectrometry (GC-MS) and chemometric tools. The discrimination among the three types of mint was successfully achieved and demonstrated evidence of ecological interaction impact in the food metabolism. The agroecological mint presented as differential compounds α-terpineol, bornyl formate, cis-carvyl propionate, cis-carveol, camphor, dihydrocarvyl acetate, dihydrocarveol, karahanaenone, nonanal, 3-octyl acetate, and trans-3-hexenyl-2 methylbutyrate. While organic and conventional mint presented as differential compounds α-cedrene, β -pinene, γ-muurolene, δ-cadinene, germacrene, terpinolene, and elemol. The majority of differential metabolites from agroecological mint are oxygenated monoterpenes, which have more intense flavor and biological activities than hydrocarbons monoterpenes and sesquiterpenes found in organic and conventional mint. Furthermore, the discrimination between organic and conventional mint was effectively performed, which demonstrated different terpenoid profiles though without implying benefits for one or another agriculture system.
