  • Sensory characteristics of acorn gels were evaluated as affected by acorn starch concentrations(7, 8, 9, 10 and 11%) and by soaking periods(4, 8 and 16 days) of acorn and acorn flour. The characteristics evaluated were color, clarity, firmness, cohesiveness, flavor and astringency. Panelists indicated in the scoring test that all the characteristics were pronounced as the starch concentration increased, except clarity, The result of ranking test on gels made with acorn starch soaked for 4, 8 or 16 days indicated that color, firmness, cohesiveness, flavor and astringency decreased, as soaking period increased. However, the soaking periods did not affect clarity of acorn gels.

  • This study aimed to investigate the effect of acorn powder and starch on the blood parameters of mice fed a high-fat diet. The moisture, crude ash, crude protein, and crude fat contents of acorns were $37.99{\pm}0.37%$, $1.61{\pm}0.06%$, $4.36{\pm}0.18%$ and $3.22{\pm}0.15%$, respectively. Acorn powder and starch contains antioxidant minerals such as selenium and zinc. The iron content was significantly higher in acorn powder than in acorn starch (p<0.05). The total cholesterol concentration was $148.50{\pm}29.72mg/dL$ in the high-fat starch diet (HFS) group, while in the high-fat diet (HF) group it was $201.50{\pm}39.15mg/dL$ (p<0.05). Serum LDL-cholesterol concentrations were significantly lower in the HFS group ($50.50{\pm}10.79mg/dL$) than in the HF group ($62.00{\pm}20.85mg/dL$; p<0.05). The serum $IL-1{\beta}$ levels in mice were not significantly different between the groups. IL-10 levels were higher in the HFP group than other groups. There is a need for strong recognition that acorns are good ingredients worldwide. It is required to develop various products using acorn powder and starch powder. There is also a need for a strategy to globalize food using acorns.
