Excessive fructose intake is associated with the increased risk of mental illness, such as depression, but underlying mechanisms are poorly understood. Our previous study found that high diet (FruD)-fed mice exhibited neuroinflammation, hippocampal neurogenesis decline and blood-brain barrier (BBB) damage, accompanied by reduction gut microbiome-derived short-chain fatty acids (SCFAs). Here, we chronic stress aggravated these pathological changes promoted development depressive-like...

This study investigated the effects of three drying methods, i.e., integrated freeze-drying, conventional and hot-air drying, on dynamic changes in volatile non-volatile flavor compounds lemon flavedo. Compared with fresh samples, methods resulted significant loss types final dried samples (P < 0.05). Conventional freeze-drying highest decrease compounds, followed by however, preserved more than drying. The amount amino acids were found to be results correlation analysis indicated positive...

Durian contains rich flavor components that undergo complex changes during drying. In this study, durian was subjected to integrated freeze-drying (IFD), conventional (CFD), and hot air drying (AD). Compared with the fresh samples, those dried by IFD, CFD, AD lost 11, 9, 7 original volatile compounds, respectively, generated 7, 6, 8 new showed a rapid then slow decreasing trend in total content However, types of amino acids soluble sugars remained unchanged each methods. Furthermore,...

Purpose: To explore the protective effect and underlying mechanism of Quzhou Aurantii Fructus flavonoids (QAFF) on Ulcerative colitis (UC). Methods: The constituents QAFF were accurately determined by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). therapeutic impacts assessed in dextran sulfate sodium (DSS)-induced UC mice, focusing changes body weight, disease activity index (DAI), colon length, histological assessment colonic tissues, levels pro-inflammatory...

The effect of hot-water blanching (HWB) on drying characteristics and product qualities dried apple slices with the novel integrated freeze-drying (NIFD) process was investigated by comparing 3 different FD methods. Compared NIFD without HWB pretreatment (VF-FD), (HWB-VF-FD) resulted in a significantly higher mass loss more sufficient freezing vacuum-frozen samples, rehydration ratio (RR), shrinkage (SR), smaller Vitamin C (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Pectin is a commonly used food additive, however, the freeze-drying characteristics of restructured strawberries with pectin addition are currently unclear. This study investigated effects 0, 3, 6, and 9 g/kg on moisture content, drying date, ratio, water state distribution during process, as well uptake volatile compounds freeze-dried strawberry blocks (FRSB). The rates at four levels presented similar early acceleration later deceleration trends. Moisture content in FRSB was linearly...

Lemon juice vesicles have abundant flavor components that can undergo complex changes during drying. Three drying methods, including integrated freeze-drying (IFD), conventional (CFD), and hot-air (AD), were studied to determine their effects on the dynamic in compounds lemon vesicles. Compared with fresh samples, final dried samples underwent IFD, CFD, AD lost seven, six volatile three, four, five amino acids, respectively; order of loss ratios respect compound content was: 82.73% CFD >...

Abstract About 1 billion people worldwide suffer from hunger, so exploring new food sources is very tempting for achieving zero hunger in the world. Edible insects (EIs) may be one of ways to solve human protein deficiency. Currently, more than 200 species EIs are consumed by over 2.5 people, especially tropical regions, as part their regular diets. However, there still a large rejection various parts In this review, we systematically summarize factors behind well improve acceptability...

Lemon fruits have a non-uniform histological structure, and are characterized by abundant volatile compounds. However, the distribution of compounds in different tissues remain unknown. Herein, electronic nose (E-nose) headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) were employed to qualitatively quantitatively analyze compound content fresh lemon fruits, while their microstructures observed using several microscopy methods. The numbers...

Abstract Deep eutectic solvents (DESs) are becoming increasingly promising as environmentally friendly solvents, and accurate prediction of their density viscosity is crucial for successful industrial application. However, existing models primarily rely on temperature variations often overlook changes in the molar ratio hydrogen bond acceptors (HBA) to donors (HBD) DESs, limiting practicality. Therefore, this study, several binary ternary DESs were synthesized using choline chloride (ChCl)...

Abstract This paper presents a systematic comparison study of the surface redox reaction mechanism for reverse water‐gas shift (RWGS) over Ni(111) and Ni(311) surfaces. Specifically, most stable intermediates kinetics involved in direct CO 2 activation water formation steps are computed with density functional theory calculations compared two different Ni The results show that , CO, O, H, OH, H O species adsorb stronger on than Ni(111). Compared to Ni(111), overall barriers lower by 23 17...

Thawing temperature is an important factor affecting the thawing quality characteristics of quick-frozen small yellow croakers. The objective this study was to reveal effect ultrasonic-assisted low-temperature (U-LT) on physicochemical and structural myofibrillar protein (MPs) croakers, select optimal temperature. results showed that color difference (ΔE) total volatile basic nitrogen (TVB-N) value croakers gradually increased with increase (2 °C, 6 10 15 °C). Compared other thawed groups,...

Summary This study investigated the effect of sorbitol impregnation on freeze–thaw damage in potato slices subjected to four freezing methods: −40 °C contact plate (−40 °C-CPF), −80 (−80 liquid nitrogen (LNF), and vacuum (VF) compare their characteristics, water status, cell activity, microstructure. Results indicate that significantly reduced drip loss (DL), time relative electrical conductivity (REC) (except for LNF) freeze–thawed slices, presenting a higher reduction REC index under...
