Freeze-drying successfully preserved the stability and quality of the encapsulated powder, with analyses confirming low moisture content (2.49–3.51%) and water activity (a_w) (0.44 to 0.52). Additional evaluation, such as powder flow property and thermal analysis, is crucial for ensuring the quality and stability of the encapsulates. Color properties, Fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy, micro-Raman spectroscopy, and X-ray diffraction (XRD) analysis confirmed successful encapsulation and indicated structural changes post-encapsulation. Among the encapsulating materials employed, gum arabic (GA) exhibited the highest encapsulation efficiency at 64.71%. Thermogravimetric analysis (TGA) indicated good thermal stability and decomposition characteristics, as evidenced by a residual mass loss of 8.06%. Notably, oleoresin encapsulated with gum Arabic (GA) retained higher DPPH antioxidant activity (66.36 ± 1.02%) and phenolic content (80.27 ± 0.11 mg GAE/g) compared to other encapsulates.

Hybrid products with a total solids content of 20% (w/w) were created by combining potato protein (10% or 15% w/w) with powdered mushrooms (10% or 5% w/w) in aqueous solutions (100 mM NaCl). Zeta-potential measurements showed both proteins and mushrooms were positively charged at pH 3, negatively charged at pH 8, with zero net charges around pH 5.0 for potato protein, pH 3.8 for oyster mushroom, and pH 3.6 for shiitake mushroom. Differential scanning calorimetry showed that potato proteins underwent irreversible thermal denaturation around 66 °C, while mushroom dispersions exhibited no thermal transitions. Potato protein solubility varied with pH, being insoluble at its isoelectric point (pH 5), whereas mushroom powders were insoluble across all pH values. Heating the protein-mushroom hybrids at 90 °C for 30 min promoted denaturation and gelation of the potato proteins. Texture profile analysis showed hybrids were harder and chewier, particularly for Shiitake mushrooms, giving a more meat-like texture. Dynamic shear rheology confirmed the formation of strong, irreversible heat-set gels, and color analysis showed a browner appearance after mushroom addition. Microscopy showed a heterogeneous microstructure due to insoluble mushroom particles in the potato protein matrix. These results suggest that potato protein-mushroom hybrids could be sustainable meat substitutes, though further research is needed on their nutritional and sensory properties.</p></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"19 4","pages":"1077 - 1094"},"PeriodicalIF":2.8,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142190190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modification of jackfruit seed starch to increase the resistant starch content makes it a promising candidate for prebiotics in the food industry.

This study chemically modified starch through carboxymethylation at different concentrations of sodium hydroxide to investigate the effect of carboxymethyl substitution on the digestible properties of the starch. Carboxymethylation exhibited a high degree of substitution from 0.28% to 0.57% as a function of the concentration of sodium hydroxide (5–10 wt%).

However, the high degree of substitution showed structural deformation of the starch granules with a decrease in crystallinity from about 35 to 1% by SEM and XRD. The degree of carboxymethyl substitution increased resistant starch content, reduced rapidly digestible starch, and had negligible impact on slowly digestible starch. Jackfruit seed starch treated with 10% by weight of NaOH was the optimal value that increased carboxymethyl substitution to 0.57% and resistant starch content to ~ 40%.

For example, plant-based milk and cheese are visually similar to their dairy equivalent, yet they lack highly phosphorylated casein micelle calcium nanoclusters. The coevolution of the casein micelle highlights the role structure plays in digestion as chymosin preferentially cleaves κ-casein at the 105-106 phe-met bond, which destabilizes the micelle surface and curdles milk into solid cheese, altering subsequent digestive kinetics, postprandial response and satiety. Food structures designed to slow digestion and their postprandial response are reinventing ingredient isolate, emphasizing the inclusion of intact plant cells in UPFs. With every intended trait imparted to the food, unintended consequences may alter satiety, food choice and postprandial responses and must constantly be reevaluated.</p></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"19 4","pages":"845 - 851"},"PeriodicalIF":2.8,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The application of wax-based oleogels is limited because of their sensitivity to shear and waxy mouthfeel. This research investigates the interaction between waxes and palm stearin in hybrid fat blends. For the oleogels, 150% of the critical gelling concentration of the waxes was used, specifically 6% berry wax (BEW), 1.5% candelilla wax (CLW) and 6% carnauba wax (CRW), all incorporated in rapeseed oil. The concentration of palm stearin (PS) in the reference system (30PS) and the hybrid fat blends was 30% (PS-BEW, PS-CLW, PS-CRW). It was found that the addition of PS to the wax-based oleogels largely affected the properties on the nano- to macroscale. On the nanoscale, the polymorphic transition from α to β of palm stearin was delayed when adding BEW, while it did not change with the other waxes. On microscale, the high melting CRW acted as a seeding template for the palm stearin in PS-CRW, resulting in the formation of fat crystals that were rich in CRW in the center. For PS-BEW and PS-CLW, it was hypothesized that the fat crystals were the result of co-crystallization. All three hybrid fat blends showed improved rigidity and shear sensitivity compared to the PS reference and the wax-based oleogels on a macroscale. These results demonstrate that the interaction between palm stearin and waxes can have a positive effect on the final structure.</p></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"19 4","pages":"1042 - 1052"},"PeriodicalIF":2.8,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11483-024-09869-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142190192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study approached the influence of different concentrations of rice bran wax (RBW) on the physical properties and stability of resveratrol-loaded glycerol-in-oleogel emulsions. The results displayed that the utilization of higher levels of RBW could result in the formation of emulsions with larger droplet sizes, more elastic behaviours, better thermal stabilities, and more needle-like β’ crystals formed in the outer continuous phase. Moreover, a higher retention of resveratrol and a lower oxidation rate were observed for the emulsions prepared with higher levels of RBW, indicating the emulsions containing higher quantities of RBW could possess better storage and oxidative stability.
