Xanthan gum (XG) and soybean fiber (SF) at varying ratios were incorporated into the batter to inhibit oil absorption in fried battered and breaded fish nuggets (BBFNs). BBFNs were prepared with 1.2% XG and SF blends (at ratios 1:3, 1:2, 1:1, 2:1, and 3:1 w/w), fried at 170 °C (40 s) followed by 190 °C (30 s), then evaluated for pickup, oil absorption, textural characteristics, and other quality attributes. Compared with the control (without the addition of XG and SF), fried BBFNs prepared with XD and SF had a significantly reduced fat content (P < 0.05). Among all the treatments, fried BBFNs with a 1:2 w/w ratio of XG and SF had the lowest fat content in the crust and the core (16.2% and 0.6%, respectively) and the highest moisture content. When compared with other treatments, the 1:2 w/w treatment group displayed a more intense golden yellow color, higher crispness, lower hardness, and a more compact structure in the crust, a greater elasticity and chewiness of the core, and the least oil penetration. The results proved that the combined addition of XG and SF in the batter can effectively inhibit oil absorption, which may be used to guide the production of low-fat fried BBFNs.
This study clearly showed that the combined addition of XG and SF at different ratios in the batter significantly affected fat content and quality attributes of fried BBFNs. The inhibition of oil absorption and improvement of color and textural characteristics in fried BBFNs depended on the XG/SF ratio added to the batter, and a 1:2 w/w ratio was found to produce the maximum enhancement.
将黄原胶(XG)和大豆纤维(SF)以不同比例掺入面糊中,以抑制油炸面糊和面包鱼块(BBFN)的吸油量。用 1.2%XG 和 SF 混合物(比例为 1:3、1:2、1:1、2:1 和 3:1 w/w)制备 BBFN,在 170°C(40 秒)下油炸,然后在 190°C(30 秒)下油炸,然后评估其吸油率、吸油量、质地特性和其他质量特性。与对照组(未添加 XG 和 SF)相比,用 XD 和 SF 制备的油炸 BBFN 的脂肪含量显著降低(P<0.05)。在所有处理中,XG 和 SF 的比例为 1:2 w/w 的油炸 BBFN 的外壳和核心的脂肪含量最低(分别为 16.2%和 0.6%),水分含量最高。与其他处理相比,1:2 w/w 处理组的外壳颜色更鲜艳、金黄色更深,外壳的酥脆度更高、硬度更低,结构更紧凑,核心的弹性和咀嚼性更大,油渗透量最少。结果表明,面糊中同时添加 XG 和 SF 可有效抑制吸油,这可能有助于指导低脂油炸 BBFN 的生产。
本研究清楚地表明,面糊中 XG 和 SF 的不同比例的组合添加对油炸 BBFN 的脂肪含量和质量特性有显著影响。吸油量的抑制以及油炸 BBFN 的颜色和质地特性的改善取决于添加到面糊中的 XG/SF 比例,发现 1:2 w/w 的比例可产生最大的增强效果。
