Rice-based complementary foods normally contain inadequate amounts of several micronutrients, such as iron, calcium, and zinc. This study aimed at improving the quality of commercially produced rice-based complementary foods. The analysis centered on identifying a rice-based complementary food that is safe, stable, sensory acceptable, and economical in terms of fortificants (iron, calcium, zinc, thiamine, folate) and effectively packaged for industrial production and distribution. Product colors were mostly in green-yellow tone and slightly changed to more yellow during storage. Sensory acceptability was affected by changes in odor and rancidity but not in color. Rancidity scores were low in aluminum foil laminated plastic bags (ALU). Lipid oxidation significantly increased during storage, but at a slower rate when sodium citrate and ALU were used. Color differences of raw products were detected but not in the cooked ones. Mineral and vitamin losses during processing were 2% to 11% and 20% to 30%, respectively, but no losses were found during storage. FeSO(4)+ NaFeEDTA added with sodium citrate resulted in the most acceptable product for all packagings. The multiple-fortified quick-cooking rice (MFQCR) developed from this study could be a potentially useful tool for combating micronutrient deficiencies among infants and young children in the countries where rice is the staple food.
以大米为基础的辅食通常含有几种微量营养素的含量不足,如铁、钙和锌。本研究旨在提高商业生产的以大米为基础的辅食的质量。分析集中在确定一种以大米为基础的辅食,该辅食在强化剂(铁、钙、锌、硫胺素、叶酸)方面安全、稳定、感官上可接受且经济,并能有效包装以用于工业生产和分销。产品颜色大多为绿黄色调,在储存过程中会略微变黄。感官可接受性受气味和酸败变化的影响,但不受颜色变化的影响。铝箔复合塑料袋(ALU)中的酸败得分较低。储存期间脂质氧化显著增加,但使用柠檬酸钠和ALU时氧化速度较慢。生产品存在颜色差异,但熟产品没有。加工过程中矿物质和维生素的损失分别为2%至11%和20%至30%,但储存期间未发现损失。添加柠檬酸钠的硫酸亚铁+乙二胺四乙酸铁钠对所有包装来说都产生了最可接受的产品。本研究开发的多重强化速煮米(MFQCR)可能是在以大米为主食的国家中对抗婴幼儿微量营养素缺乏的一种潜在有用工具。
