Extensive research on the irradiation of fresh meat and poultry has been carried out during the past 40 years; yet there is a need for consideration of combined use with other technologies such as modified atmosphere (MA) packaging. Some of the past work has focused on spoilage microorganisms and pathogens, whereas other reports emphasize the sensory quality of fresh meat and poultry. Reports published indicate that the effects of irradiation in conjunction with packaging vary depending upon the kind of meat and poultry and the atmosphere composition in the package. Irradiation may result in off-flavor and/or odor and discoloration of fresh meat and poultry in packages containing air (oxygen). One concern is that pathogens may grow and/or produce toxins in irradiated meat or poultry packaged using modified atmospheres because of a lack of competing organisms. This is of even greater concern if spoilage is suppressed and does not provide the usual warning signals. On the other hand, even though there is some evidence of the growth of pathogens in temperature-abuse conditions, most reports have indicated that spoilage preceded toxin production. Therefore, considering the sensory quality and concerns for safety, the effects of irradiation in combination with vacuum or MA packaging of fresh meat and poultry should be studied further. More complete information is needed to ensure the appropriate use of vacuum or MA packaging in combination with irradiation for the safety of fresh meat and poultry.

The deammonification process is an efficient alternative to remove nitrogen from wastewater with a low carbon/nitrogen ratio. However, the reactor configuration and operational factors pose challenges for applications in treatment systems to remove nitrogen from municipal and industrial wastewater on a large scale. To address this gap, this study evaluated a new deammonification strategy using a single-stage membrane aerated biofilm reactor (MABR), operated with continuous flow, under different hydraulic retention times (HRT) in the post-treatment of poultry slaughterhouse wastewater with a low nitrogen load, similar to domestic wastewater.

During the harvest of Ilex paraguariensis, approximately 2-5 tons per hectare of thick stems are left on the soil surface. The outer portion of these stems, referred to as the coproduct, constitutes 30% of the total residue mass. Although this coproduct has been partially characterized in terms of its phytochemical profile, its technological applications remain unexplored.

Background: This study aimed to investigate associations between sociodemographic factors and dietary intake among a diverse population of early adolescents ages 10-13 years in the United States.
Methods: We examined data from the Adolescent Brain Cognitive Development (ABCD) Study in Year 2 (2018-2020, ages 10-13 years, N = 10,280). Multivariable linear regression models were conducted to estimate the adjusted associations between sociodemographic factors (age, sex, race and ethnicity, household income, parental education) and dietary intake of various food groups, measured by the Block Kids Food Screener.

This study was aim to investigate the effects of lipoic acid (ALA) on performance, meat quality, serum biochemistry and antioxidant function of broilers under heat stress (HS). Two hundred1-day-old Cobb broilers were randomly divided into four treatment groups and each treatment consisted of 4 replicates of 10 broilers each. The treatment group adopts a 2 × 2 two-factor setting, which is divided into two diets (basic diet or 250 mg/kg ALA diet) and two temperatures (24 ± 1℃ or 33 ± 1℃).
