Food drying is an essential preservation operation in the food industry and contributes to the development of shelf-stable ingredients and consumer products. Industrial food-drying technologies, including pretreatments, processing methods, equipment, and quality-control systems, have advanced considerably in recent years. Novel approaches, including microwave assisted drying, ultrasound-assisted drying, high-electric-field drying, heat-pump drying, and refractance-window drying, have…

Background: Vitamin D is essential for calcium absorption, skeletal mineralization, and musculoskeletal health. However, the relationship between serum 25-Hydroxyvitamin D [25(OH) D], Body Mass Index (BMI), and DEXA-defined osteopenia or osteoporosis remains debated, particularly in populations with heterogeneous nutritional, lifestyle, and clinical risk factors.

Objective: This study evaluated the distribution of vitamin D status and Bone Mineral…

Isolation and identification of fungi pathogens causing kolanut spoilage across Markets in Awka was carried out using standard laboratory procedures. Randomized block sampling method was used in sample collection for the study. Potato dextrose agar was used to prepare innocula for the diseased kolanuts collected. The results of the study revealed the presence of Aternaria alternata, Fusarium oxysporum, Aspergillus niger and Aspergillus flavus. Aspergillus niger was absent only in kolanut…

The Coconut (Cocos nucifera) fruit is a fibrous drupe with multiple uses and is widely disseminated on almost all continents.

The study was carried out in two nurseries, one in Oby Okoli and another in Udoka Estate. The medium used for the isolation of pathogens in the samples collected was Sabouraud Dextrose Agar…

The isolation and identification of fungi pathogens causing yam rot across markets in Awka and the control of this rot using botanicals was carried out using standard laboratory procedures. Randomized block sampling was used in the sample collection for this study. For the in vitro analysis, potatoes dextrose agar was used to prepare innocula for the 4 unhealthy yam tubers collected. Aqueous extract of seeds of Xylopia aethiopica and Piper guineense was used for growth inhibition treatment…

Natural textile dyes, derived from plants, animals, and microorganisms, are increasingly used in food and nutrition to replace synthetic colorants due to their safety, sustainability, and health-promoting properties. These colorants (e.g., turmeric, beetroot, chlorophyll) often provide antioxidant, anti-inflammatory, and antimicrobial benefits.
