The effect CDs/CH on the modified‐atmosphere‐packaged during were investigated. RESULTS CDs monodispersed spherical morphology size distribution 0.54–0.83 nm. Interaction CH had generation strong hydrogen bond....

Abstract BACKGROUND Gel‐like constructs can be produced using an extrusion‐based 3D food printing (3D‐FP) technique. Nostoc sphaeroides biomass is a natural gel material. Considering its good nutrition and rheological properties, these algae were chosen in this study as supply material (ink) for 3D‐FP. With material, the system was set model, behavior investigated. Furthermore, 3D‐FP mechanisms explained through low‐field nuclear magnetic resonance measurements. RESULTS Results indicated...

Abstract BACKGROUND Microwave‐assisted pulse‐spouted bed freeze‐drying (MPSFD) uses microwave heating to substitute the customary conduction during freeze drying (FD), resulting in high‐quality dried samples with a short time. The aim of this study was determine effect MPSFD on volatile compounds and structural aspects Cordyceps militaris . In order highlight MPSFD, FD (recognized for its products) hot‐air dying (HD; most commonly used) were also evaluated using headspace solid‐phase...

Infrared freeze drying (IRFD) utilizes infrared radiation as a novel heating source in (FD), leading to high-quality dehydrated products and less time. The present study aimed investigate the effects of IRFD on characteristics (drying time energy consumption), volatiles, physical structure nutritional properties Rosa rugosa flower. In addition, (FD) hot air (HAD) were also evaluated comparison with IFRD method respect product quality parameters.Fifty-six volatile compounds identified fresh...

The thawing process is regarded as an essential step before the consumption of frozen foods. This study aimed to evaluate possibility ultrasound red radish and explore characteristics thawing. influence low-frequency (LFU) on efficiency cylinders in air water mediums was investigated. effects different ways thawing, including (AT), (WT), refrigeration (RT), ultrasound-assisted (UWT), microwave (MT) time quality samples studied.The results showed that decreased remarkably assisted by LFU. As...

Parvalbumin (PV) is one of the major allergens in fish. The aim our present work was to research influence mechanism glycation with different reducing sugars (glucose, fructose, ribose, lactose, and galactose) on immunoglobulin E (IgE) G (IgG) binding capacity structure changes PV Alaska Pollock. glycated glucose or fructose (PV-Glu/ PV-Fru) exhibited higher IgE/IgG capacities than that galactose, lactose. During glycation, lysine (Lyr), tyrosine (Tyr), phenylalanine (Phe) were gradually...

Abstract BACKGROUND In order to investigate the effect of ultrasound dielectric pretreatment on oxidation resistance vacuum‐fried apple chips, slices were pretreated at ultrasonic powers 150, 250 and 400 W for times 10, 20 30 min before vacuum frying. The quality fried evaluated by testing properties comparing moisture content, oil uptake, color, acid value (AV) peroxide (PV) chips. RESULTS Ultrasonic treatment significantly changed slices. Moisture contents chips decreased with increasing...

Abstract BACKGROUND Young barley grass powder contains abundant nutrition and its antioxidant substances are severely impaired by radiation ( 60 Co) sterilization. To overcome product quality degradation, radiofrequency pasteurization was conducted using pilot‐scale equipment (27 MHz, 6 kW) with electrode gaps of 12, 14 16 cm, while hot‐air (80 °C) used for comparison. RESULTS Assessment suggested that uneven heating improved the cm gap. With an increase gap, microbial inactivation needs...

Effect of low temperature blanching at 50°C (for 15, 30, and 60 min) high 100°C (30, 60, 120 s) on volatile compounds structural properties Cordyceps militaris dried by microwave-assisted pulse-spouted bed freeze-drying were investigated. A total 83 identified. Blanching remarkably decreased the ketones alcohols while contributed to formation alkanes. The absence 993 cm−1 appearance near 1548 in samples blanched observed, indicating would cause loss polysaccharides degradation proteins....

Cordyceps militaris is a medicine and food dual-purpose mushroom extensively cultivated consumed in East Southeast Asia for centuries. However, it has an extremely short shelf life of 3-4 days at room temperature. C. was pasteurized 10, 20, 30 min by radio-frequency (RF) electrode gap 20 mm. The effect RF heating on the microbial load, color, texture, flavor attributes evaluated compared with those sterilized conventional high-pressure steam.RF contributed to good uniformity, uniform...

Abstract BACKGROUND As a pretreatment before drying, the purpose of osmotic dehydration (OD) is to reduce initial water content samples and shorten drying time. When OD combined with pulse vacuum, mass transfer enhanced. Furthermore, properties materials, which affect absorption dissipation microwaves, can be changed by OD. In this work, pulsed vacuum (PVOD) sucrose solution was adopted microwave freeze‐drying (MFD). The effects PVOD on characteristics quality dried products were studied....

Skeletal muscle is a promising tissue for therapeutic gene delivery because it highly vascularized, accessible, and capable of synthesizing protein therapies or vaccines. The application electric pulses (electroporation) enhances plasmid DNA expression by increasing membrane permeability. Four hours after electroporation, we evaluated acute changes in mouse skeletal to identify regulated genes genetic pathways. RNA sequencing followed functional annotation was used evaluate differentially...

Starch-based foods have a large consumer base worldwide. It is known that the quality of freeze-dried starch-based products subject to deterioration during production process. The present study was unprecedented carried out examine effects freeze-drying on cross-linking between components gelatinized system. results showed retrogradation starch in process dehydration, weakening binding capacity substrate and water product interaction strength were key mechanisms leading wheat conditioned...

Selecting differentially expressed genes (DEGs) is one of the most important tasks in microarray applications. However, sample sizes typically used current cancer studies may only partially reflect widely altered gene expressions cancers. By analyzing three large datasets, we show that, each cancer, a wide range functional modules are and have high disease classification abilities. The results also that shared across diverse cancers cover functions, suggesting hints about common mechanisms...
