This study presents the rheological properties of quince seed gum (Q) solution in comparison with xanthan gum (X) and locust bean gums (L) and the polymeric interactions of different ratios of Q:X and Q:L blends (1:1, 1:3 and 3:1). Q exhibits greater and stronger elastic properties than X and L. The frequency and temperature stability of Q and X are both higher than that of L. The viscoelastic properties of Q:X and Q:L solutions were found to be higher than those of the individual solutions. The higher polymer entanglements observed in Q:L blends resulted in enhanced synergistic interactions and thixotropy compared to Q:X. 3QX exhibited an enhanced elastic structure, but the best synergism was observed for 3QL due to the establishment of a stronger intermolecular bond for gelling. The lower tan δ observed with increasing Q indicate a Q-induced synergistic interaction with L. At all temperatures, 3QL showed the highest thixotropy. The combination of Q and L resulted in the formation of a true gel, with the higher gel strength being observed for QL and 3QL. This study shows that Q:L and Q:X combinations can yield desired flow properties. In particular, L provides a firmer gel network with Q.

The effect of partial replacement of cereals by increasing levels of almond hulls (AH) was tested in twenty-four lambs distributed into three dietary treatments: 1) diet without replacement of cereals with AH (0AH); 2) diet with replacement of cereals with 9% of AH (9AH); and 3) diet with replacement of cereals with 18% of AH (18AH). All diets included 40% dehydrated lucerne and 5% soybean oil. Dry matter intake, growth performance, feed costs, carcass traits, meat quality, and lipid oxidative stability of raw and cooked meat during refrigerated storage were evaluated.

PpZAT12, a transcription factor differentially expressed in peach varieties with distinct susceptibility tochilling injury (CI), is a potential candidate gene for CI tolerance by regulating several identified gene targets. ZAT (zinc finger of Arabidopsis thaliana) proteins play roles in multiple abiotic stress tolerance in Arabidopsis and other species; however, there are few reports on these transcription factors (TFs) in fruit crops. This study aimed to evaluate PpZAT12, a C2H2 TF up-regulated in peach fruit by a heat treatment applied before postharvest cold storage for reducing chilling injury (CI) symptoms.

In this study, xyloglucan (XG) based edible coatings were developed and combined with a bioactive compound, Borassus flabellifer seed coat extract (BFE). The effect of designed edible coatings on the quality of strawberry fruits was investigated over an 8-day storage under ambient conditions. The results revealed the preservation effects in intrinsic properties of coated strawberries that the XG/BFE coated strawberries showed superior maintenance of qualitative parameters over uncoated strawberries, showing delayed weight loss, pH, and total soluble solids, tritratable acidity, retained firmness and lightness, as well as minimized the total color difference at the end of storage.

The biological effects of marolo (Annona crassiflora Mart.) seed byproducts, a native fruit of Brazilian Cerrado, have not been extensively studied. We evaluated the chemopreventive potential of marolo seed almond flour (MSAF) and marolo seed film flour (MSFF) and correlated the results obtained with the antioxidant capacity presented by the seed.

Chronic non-communicable diseases (NCD), such as cardiovascular diseases, diabetes, and cancer, dominate global mortality, besides compromising the quality of life. Unhealthy habits like sedentary lifestyles and poor diets escalate NCD risks. Conversely, the consumption of phenolic compounds and carotenoids has shown promise in reducing NCD risks.
