Riboflavin-loaded soy protein isolate cold gel treated with combination of high intensity ultrasound and high hydrostatic pressure: Gel structure, physicochemical properties and gastrointestinal digestion fate

Open access

Abstract

Transglutaminase (TGase) was added to soy protein isolate (SPI) dispersion after the combination treatment of high intensity ultrasound (HIU) and high hydrostatic pressure (HHP) to catalyze the formation of cold gel, which was used to encapsulate riboflavin. The structure, physicochemical properties and in vitro digestion characteristics of riboflavin-loaded SPI cold gel were investigated. HIU-HHP combined treatment enhanced the strength, water retention, elastic property, thermal stability and protein denaturation degree of riboflavin-loaded SPI cold gels, and improved the gel network structure, resulting in a higher encapsulation efficiency of riboflavin and its chemical stability under heat and light treatment. HIU-HHP combined treatment reduced the erosion and swelling of SPI cold gel in simulated gastrointestinal fluid, and improved the sustained release effect of SPI gel on riboflavin by changing the digestion mode and rate of gel. In addition, HIU-HHP combined treated gels promoted the directional release of riboflavin in the simulated intestinal fluid, thereby improving its bioaccessibility, which was related to the secondary structure orderliness, tertiary conformation tightness and aggregation degree of protein during the gastrointestinal digestion. Therefore, HIU-HHP combined treatment technology had potential application value in improving the protection, sustained/controlled release and delivery of SPI cold gels for sensitive bioactive compounds.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Over-processing conditions (e.g., prolonged treatment duration or excessively high frequency) may disrupt the gel matrix, thereby increasing the accessibility of enzymes to the protein gel matrix.

    From Designing Protein Gels for Nutrient Delivery: From Formulation to Digestion (2026) · cites this paper as Mao et al. 2024

    The Results and discussion section on protein digestibility says a stable, compact gel network hinders digestive-enzyme permeation, supporting the link between gel structure and enzyme access. But the paper does not report that prolonged processing or excessively high frequency disrupts the matrix; its tested treatments instead strengthened the gel network and reduced digestibility. No page number is available in our copy. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • This structural modification from ultrasound contributes to increased mechanical strength of protein gels, which in turn impairs digestive enzyme activity and reduces digestibility.

    From Designing Protein Gels for Nutrient Delivery: From Formulation to Digestion (2026) · cites this paper as Mao et al. 2024

    The Results and discussion section (“Protein digestibility of gel during gastrointestinal continuous digestion”; page unavailable) reports that ultrasound-treated gels had lower digestibility and suggests that a more compact network hindered digestive enzymes from entering the gel. It does not show that the treatment impaired the enzymes’ activity; the proposed mechanism is reduced access to the protein, not reduced enzyme activity. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Under optimal processing conditions, ultrasound treatment can unfold protein molecular structures, exposing internal functional groups that enhance molecular interactions among components.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
