The combination of high-power ultrasound (HPU) and bamboo fiber (BF) was investigated as a strategy to produce phosphate-free meat emulsions. The samples were made with the addition of 0 and 0.25% of alkaline phosphate and 0, 2.5, and 5% BF. Immediately after filling, the samples were sonicated for 0 or 27 min at normal mode, 25 kHz, 60% amplitude, and 20 °C. The samples made with BF and without phosphate showed higher emulsion stability compared to the control made with phosphate. The addition of 2.5% BF effectively compensated for the texture changes due to the absence of phosphate. HPU improved the effect of BF on the texture of meat emulsions by increasing cohesiveness. No significant impact of HPU and BF was observed on the oxidative quality of the samples. However, the instrumental assays and the sensory evaluation demonstrated that the absence of phosphate increased the lipid oxidation of the samples from the beginning of storage.

This study aimed to investigate the effect of ultrasound-assisted cross-linking of myofibrillar protein (MP) emulsions on the enhancement of rheological and tribological properties of emulsion-filled gel. The micro-morphology, texture, water hold capacity (WHC), chemical forces, linear shear rheological behavior, large amplitude oscillatory shear (LAOS), oil-released content, and simulated oral friction of the water-filled gel (WP-G), the original MP fabricated emulsion-filled gel (NP-G), the crosslinked MP fabricated emulsion-filled gel (NPG-G), and the ultrasound treated crosslinked MP fabricated emulsion-filled gel (NPGU-G) were determined. Results indicated that emulsion as filler phase significantly improved the rheological and tribological properties of the gel, especially for the ultrasound-assisted MP emulsion-filled gel (NPGU-G) group, the smaller droplet size of emulsion contributed to the density and structural uniformity of the gel.

Fats are essential nutrients, but excessive intake can lead to obesity and certain cardiovascular diseases. In this study, an emulsion gel was prepared using alkali heat treatment with soy protein isolate (SPI) and konjac glucomannan (KGM) as a fat substitute, while pork fat was used as the control. Gel strength, rheological properties, and water holding capacity of soy protein isolate-konjac glucomannan (SPI-KGM) emulsion gel improved progressively with higher KGM content.

is a subtropical fruit rich in dietary fibers, carotenoids, vitamins, minerals, and polyphenols. To substitute synthetic additives, its extracts could become an interesting proposal to preserve quality while adding desirable characteristics to meat products. This study aimed to develop healthier chicken patties (with a structured animal fat replacer) added with prickly pear extract (PPE).

The objective of this study was to investigate the effects of retrograded resistant starch (RS3) (0, 2%, 4% and 6%; /) on the emulsion gel properties stabilized by myofibrillar proteins (MPs) and in vitro protein digestibility of the gels. The RS3 was prepared from corn or potato starch using the gelatinization-ultrasound-retrogradation method. The results showed that the addition of RS3 decreased the surface hydrophobicity ( < 0.

Excessive intake of saturated fatty acids poses health risks, necessitating the development of healthier animal fat substitutes. In this study, high internal phase emulsion (HIPE) stabilized by egg yolk-hydroxypropyl distarch phosphate (EY-HPDSP) complex was used as a fat replacer in processed meat. The effect of fat replacement ratios (0 %, 50 %, 100 %) and reheating core temperature (75 ℃, 85 ℃, 95 ℃) on physico-chemical properties, microstructure and protein digestibility of processed meat was investigated.
