High-pressure processing (HPP) is used as a non-thermal approach for controlling microbial viability. The purposes of this study were to (i) establish the decimal reduction times (D-values) for pathogenic bacteria during 350 MPa HPP treatment,; (ii) evaluate the impact of 350 MPa HPP on total plate count (TPC), yeasts and molds (YM), and lactic acid bacteria (LAB) in camel milk; (iii) investigate the behavior of several spoilage-causing bacteria during storage at 4 °C and 10 °C for up to 10 d post-HPP treatment; and (iv) assess the effect of HPP on the protein degradation of camel milk. The D-values for , O157:H7, and spp.

The increased use of dairy fat in various applications is facilitated by its fractionation into hard and liquid fractions. Herein, the fractionation of bovine ghee and buffalo ghee was investigated, and triacylglycerol (TAG) profiles of milk fat fractions and 2 categories of infant formulas fat were quantified by using ultra-performance convergence chromatography quadrupole time-of-flight mass spectrometry (UPC-Q-TOF-MS) using carbon dioxide as the mobile phase. Furthermore, the thermal behavior of the different samples was evaluated, and tocopherols content was also quantified.

The production of set-type camel milk yogurt is challenging due to its unique physicochemical properties, which differ from those of other milk species. The present study aimed to evaluate the effects of camel milk supplementation with different levels (0% [WPCA0], 3% [WPCA3], and 6% [WPCA3]) of whey protein concentrate (WPC) on the texture, rheological properties, antioxidant capacity, and biological activity of camel milk yogurt compared with bovine milk (BM) yogurt. These characteristics were evaluated before and after in vitro digestion of yogurt samples after 1 and 15 d of storage at 4°C.

This study was conducted to develop biodegradable films using a combination of carboxymethyl cellulose (CMC), polyvinyl alcohol (PVA) and purified leaves extract of Astragalus tribuloides (ATE). Various traits of the films, including their morphology description, thermal behavior, tensile/elongation properties and physical characteristics were examined. The scanning electron microscope (SEM) photographs showed smooth surface with small amounts of ATE, but rougher with higher concentrations of 1.

Labneh is a popular fermented dairy product, which contemporarily has diversified into a varied range of styles, formulated with the inclusion of multiple additives, and is sourced across the globe. This has driven labneh's emergence as a complex product with varying textural and rheological characteristics. The lack of scientific literature about labneh products available in the United Arab Emirates (UAE) market and their characterization has prompted this study.

Cellular agriculture aims to meet the growing demand for animal products. However, current production technologies result in low yields, leading to economic projections that prohibit cultivated meat scalability. Here we use tangential flow filtration for continuous manufacturing of cultivated meat to produce biomass of up to 130 × 10 cells per ml, corresponding to yields of 43% w/v and multiple harvests for over 20 days.

Manuka honey (MH) has garnered much attention due to its remarkable antimicrobial, anticancer, immunomodulatory and wound-healing properties. This study compared the antiproliferative effects of raw and powdered MH (pMH) on various human and murine cancer cell lines. A detailed metabolomics analysis was also carried out using untargeted ultrahigh-performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry (UPLC-Q-TOF-MS) to compare the constituents in raw MH and pMH.

Small bowel obstruction (SBO) in pregnancy is exceedingly rare. Management of SBO in the third trimester may pose particular challenges, as clinicians must determine whether or not the delivery of the fetus is indicated. In this report, we review the case of a patient in her mid-20's with no prior surgical history who presented with nausea and vomiting at 34 weeks of gestation and was ultimately diagnosed with an SBO.

Human viruses and viruses from animals can cause illnesses in humans after the consumption of contaminated food or water. Contamination may occur during preparation by infected food handlers, during food production because of unsuitably controlled working conditions, or following the consumption of animal-based foods contaminated by a zoonotic virus. This review discussed the recent information available on the general and clinical characteristics of viruses, viral foodborne outbreaks and control strategies to prevent the viral contamination of food products and water.
