为了更好地丰富老年食品市场,满足吞咽困难群体多样化营养需求,该研究以带鱼鱼糜为原料,通过测定凝胶强度、全质构、持水性、动态流变学、白度、水分状态分布、蛋白二级结构、微观结构、体外消化率、国际吞咽障碍食物标准(international... 为了更好地丰富老年食品市场,满足吞咽困难群体多样化营养需求,该研究以带鱼鱼糜为原料,通过测定凝胶强度、全质构、持水性、动态流变学、白度、水分状态分布、蛋白二级结构、微观结构、体外消化率、国际吞咽障碍食物标准(international dysphagia diet standardisation initiative,IDDSI)等级等指标,研究发芽糙米匀浆对带鱼鱼糜凝胶品质的影响。结果表明,发芽糙米匀浆的加入使带鱼鱼糜的凝胶强度从649.91±64.35 g·mm显著降低到480.93±98.84 g·mm(P<0.05);与空白组相比,糙米添加组的硬度、胶着度和咀嚼性均显著降低(P<0.05),具体来说,硬度从585.63±61.35 N降低到399.87±51.23 N,胶着度从81.14±10.23 N降低到50.16±7.13 N,咀嚼性从30.14±5.00 N降低到18.31±3.97 N;白度值变化不显著(P>0.05);持水性从77.92%±0.73%显著增加到81.92%±1.40%(P<0.05),糙米匀浆的加入改变了水的状态分布,增强蛋白与水的结合;体外消化模拟结果显示,发芽糙米匀浆显著提高了带鱼鱼糜的体外消化率和胃蛋白酶消化率(P<0.05)。与空白组相比,添加糙米匀浆的鱼糜凝胶网络结构更加疏松,鱼糜凝胶中肌原纤维蛋白的α-螺旋结构含量从47.12%±1.09%显著增加到52.74%±1.65%(P<0.05),β-折叠结构含量从25.67%±0.84%显著降低到20.99%±0.65%(P<0.05)。IDDSI等级测定结果表明空白组为6级,糙米添加组为5级。此外,糙米添加组中检测出多种清香味物质,其中醛类、酮类、醇类和酯类化合物显著增加(P<0.05),而烷烃类化合物显著降低(P<0.05)。综合各项指标得出,添加适量的发芽糙米匀浆可以软化带鱼鱼糜的凝胶特性。该研究结果可为鱼糜类老年食品的研发提供理论依据与参考。 展开更多

Over the last two decades, food allergens are being recognized as one of the food hazards. This serious food safety issue is being addressed in different countries not only in terms of their biological and clinical characteristics, but also in terms of various standards of allergen management in food industries. This abnormal immune response caused by food allergens affects the quality of life especially in children and influences their overall health and retards normal growth, along with they suffer from ailments like eating disorders, depression, sometimes even death which is the most adverse impact of food allergy. Every country has their own set of guidelines to deal with the food allergens especially developed countries, food allergen guidelines is not well documented in developing countries. FAO/WHO is providing assistance to developing countries in strengthening their food safety guidelines. The Codex Alimentarius was formulated by the two organizations FAO/WHO in the year 1960; it is a collection of food standards in a integrated, codified style, together with associated material such as codes of hygiene and good manufacturing practices that should be followed by industries during various production stages of a food item. In both developed and developing nations, the Food Chemical Codex or the Codex Alimentarius aims to protect public health and implement fair trade practises for the trading of food items. 展开更多
