AI Article Synopsis
- Different extraction methods affect the yield and properties of pectin from passion fruit, with ultrasonic-assisted extraction (UA) yielding 6.5%, similar to acid extraction (AE) at a 60-minute mark (5.3%), but UA pectin has poor emulsion stability.
- Ultrasonic-assisted steam explosion (USEA) resulted in higher emulsion stability with an improved protein content of 0.62% and lower molecular weight (0.72 × 10 Da).
- Both steam explosion (SEA) and USEA showed high pectin yields (9.9% and 10.7%) but led to lower degrees of esterification (59.3% and 68.5%),
Article Abstract
Extraction methods directly affect pectin extraction yield and physicochemical and structural characteristics. The effects of acid extraction (AE), ultrasonic-assisted acid extraction (UA), steam explosion pretreatment combined with acid extraction (SEA) and ultrasonic-assisted SEA (USEA) on the yield, structure, and properties of passion fruit pectin were studied. The pectin yield of UA was 6.5%, equivalent to that of AE at 60 min (5.3%), but the emulsion stability of UA pectin was poor. The pectin obtained by USEA improved emulsion stability. Compared with UA, it had higher protein content (0.62%), rhamnogalacturonan I (18.44%) and lower molecular weight (0.72 × 10 Da). In addition, SEA and USEA had high pectin extraction yields (9.9% and 10.7%) and the pectin obtained from them had lower degrees of esterification (59.3% and 68.5%), but poor thermal stability. The results showed that ultrasonic-assisted steam explosion pretreatment combined with acid extraction is a high-efficiency and high-yield method. This method obtains pectin with good emulsifying stability from passion fruit peel.

Background: Oils from various sources are vital nutritional components with a variety of roles in our body. Niger seed (Guzoita abyssinica) is endemic to Ethiopia and is among the major oil seed crops grown in the country. The fatty acid composition and the concentration of other bioactive phytochemicals in it vary with species type, geographical origin, cultivation season, and varietal types.

Atopic dermatitis (AD), also known as eczema, is a chronic or relapsing inflammatory skin disease characterized by repeated exacerbations and remissions. Here, we investigated the effects of squid phospholipids (PLs) extracted from Todarodes pacificus on AD. The composition of squid PLs was analyzed using thin-layer chromatography and high-performance liquid chromatography, and the effects of PLs on AD were investigated using a rat paw edema model and an AD-like mouse model (NC/Nga mice).

As the demand for clean water intensifies, developing effective methods for removing pollutants from contaminated sources becomes increasingly crucial. This work establishes a method for additive manufacturing of functional polymer sorbents with hollow porous features, designed to enhance interactions with organic micropollutants. Specifically, core-shell filaments are used as the starting materials, which contain polypropylene (PP) as the shell and poly(acrylonitrile-co-butadiene-co-styrene) as the core, to fabricate 3-dimensional (3D) structures on-demand via material extrusion.
