In addition, longer time high...

To improve the availability of citrus essential oil (CEOs), nanoemulsions based on chitosan nanoparticles loaded with CEOs were prepared by emulsion-ionic gelation technique.

ABSTRACT Campylobacter infection is one of the major causes ovine abortions worldwide. Historically, fetus subsp. was cause -associated abortion in sheep; however, jejuni increasingly associated with sheep abortions. We examined species distribution, genotypes, and antimicrobial susceptibilities abortion-associated isolates obtained from multiple lambing seasons on different farms Iowa, Idaho, South Dakota, California. found that C. has replaced as predominant causing United States. Most...

To evaluate the influence of extraction solvents on antioxidant and antimicrobial activities pulp seed Anisophyllea laurina R. Br. ex Sabine fruits. The antibacterial extracts were tested by using disk diffusion method against eight bacterial strains three fungal strains. Total phenolic, flavonoid, monomeric anthocyanin tannin contents, determined spectrometric methods. analysis extract revealed strong radical scavenging capacity total phenolic content (4 329.66 mg gallic acid/100 g), while...

Abstract Two drying methods, namely intermediate-wave infrared (IWIR) and hot-air (HA), were compared in preparation of mushroom chewing tablets (MCT). It was observed that IWIR enhanced the rate shortened time required for MCT. technology better than HA preserving thermal-sensitive materials by thermo gravimetric analysis. In addition, had a significant effect on flavor samples, which would be used retaining ingredients conducive to processing product. The results indicated may have...

Baixi sufu (BS) is a traditional Chinese spicy fermented bean curd manufactured with natural starter. In this study, the bacterial and fungal communities during BS fermentation were determined by culture culture-independent method of high-throughput sequencing (HTS). Correlation analyses performed to select microorganisms potentially contributing fermentation.During BS, 162 97 strains isolated identified, total 268 314 287 844 high-quality sequences analyzed. general, lactic acid bacteria...

This study elucidated the mechanisms underlying immunoregulatory and gut-microbiota-modulating effects of Flammulina velutipes residue polysaccharide (FVRP) using cyclophosphamide (CTX)-induced mouse models. FVRP supplementation alleviated CTX-induced intestinal damage boosted antioxidant enzyme activity cytokine secretion. Additionally, enhanced diversity total species richness gut microbiota, promoting proliferation beneficial bacteria (e.g., Prevotellaceae), while reducing abundance...

Hops impart flavor to beer, with the volatile components characterizing various hop varieties and qualities. Fingerprinting, especially fingerprinting, is often used identify 'flavor products' because inconsistencies in description of may lead an incorrect definition beer quality. Compared fingerprinting simpler easier.We performed using head space-solid phase micro-extraction gas chromatography-mass spectrometry combined similarity analysis principal component (PCA) for evaluating...

Abstract Partially hydrogenated vegetable oil (PHVO) has recently been used to make oil‐based candles. However, its use is limited primarily container candles because of inherent physical properties, such as brittleness when a hard material produced, and greasiness it soft by low degree hydrogenation. Such lacks the most desired cohesiveness elasticity compared commercial petroleum paraffin beeswax. To improve thermal properties PHVO, epoxidation, ring‐opening reaction, esterification were...

Lactobacillus plantarum WUH3 and M4L1 have high homology contain genes encoding Plantaricin EF. The bacteriocin-WUH3 bacteriocin-M4L1, using ethyl acetate, anion exchange, gel chromatography, RP-HPLC, were purified for identifying the bacteriocins mining silent genes. molecular weight of measured by MALDI-TOF-MS was 4299.801 Da, highly matched with E analyzed whole-genome sequencing. Q-TOF-MS/MS analysis predicted amino acid sequence novel bacteriocin-M4L1 as 3748.9643 Da. sequencing results...

The fermentation medium of Micromonospora Y15 was optimized to enhance the production antimicrobial metabolites with activity tested against Listeria monocytogenes. First, optimal components (carbon source, nitrogen source and inorganic salt) were determined by single factor experiment. Second, Plackett–Burman experiment used screen significant factors. Third, steepest ascent undertaken figure out region Finally, central composite conducted optimize final components. results suggested that...

As a traditional Chinese condiment, douchi has attracted attention in Asian and European countries because of its high nutrient content unique flavors. Douchi is currently produced mostly by natural fermentation. The quality this way affected microbial species, temperature, humidity, season, so the physical chemical properties product, flavor substances, safety vary. In study, four safe strains with protease activity, screened previously, namely Bacillus velezensis, amyloliquefaciens,...

Tartary Buckwheat dried noodles were prepared by substituting wheat flour with 0–80% content of mixtures (TBFM), which comprised extruded-micronized and micronized (1:1, w/w). Cooking properties, texture, colour, flavonoid antioxidant activities investigated to evaluate the effect on quality noodles. Hardness noodle samples increased slightly internal networks became more compact increase TBFM. The 10–60% levels TBFM performed similar or better cooking qualities including cooked breaking...
