Malnutrition is a global issue linked to energy or nutrient imbalances, often resulting in deficiencies or overweight. Dairy products, rich in macronutrients and micronutrients, are a potential solution. However, processing, storage, and digestion can lead to nutrient loss. To enhance nutritional value, functional ingredients like microencapsulated compounds are used. This study focused on assessing the bioaccessibility of microencapsulated ingredients in cottage cheese, their impact on sensory attributes, and shelf-life. Two microencapsulated ingredients were studied: high oleic palm oil (HOPO), encapsulated using spray drying (SD) and a refractive window (RW) drying technique. The bioaccessibility of these ingredients was evaluated using the INFOGEST in-vitro digestion model. Results showed that HOPO encapsulated via SD in cottage cheese (CSD) preserved oleic and linoleic acids best, and via RW in cottage cheese (CRW) preserve vitamins in 63 % and antioxidants in 96 %. This highlights the effectiveness of microencapsulation techniques in enhancing dairy product functionality and a 72 % of fatty acids release suggesting potential strategies for combating malnutrition through fortified dairy products.

Oral candidiasis may be white or red, classically presenting as cottage-cheese consistency plaques associated with symptoms of a burning mouth and dysgeusia. Standard first- and second-line antifungal medications can easily and safely be prescribed by dermatologists.

Article Synopsis
- The study focuses on analyzing lactic acid bacteria strains found in Ethiopian cottage cheese to understand their beneficial properties and potential risks, such as antibiotic resistance.
- Whole genome sequencing of three strains revealed that 54B and 54C are related yet distinct; neither strain contains harmful resistance or virulence factors and showcases valuable enzyme capabilities.
- The findings indicate that these strains could be safely used in food preservation and as means to prevent or treat infections, highlighting their probiotic potential.

Miniaturized procedures for chemical analysis give the possibility of a significant reduction in quantities of organic solvents used during isolation and determination processes. Liquid-liquid microextraction (LLME) using butanol as an extractant was investigated to selectively isolate oxytetracycline (OTC) antibiotic residues from dairy products. The optimal conditions of LLME were established after deproteinization of the samples.
