Abstract

Background and Objectives

This study investigated the effect of using different phenolic-containing grain brans on nanoparticle properties.

Findings

This study successfully synthesized nanoparticles from bran flour isolated from three different sources: sorghum (Sumac and Burgundy) and hard red winter wheat (cv. 1863). The phenolic contents of the three brans were measured as 33.40, 4.98, and 1.59 mg GAE/g, respectively. NPs synthesized from the bran flour had phenolic content measuring 6.41 (sorghum-Sumac bran), 5.31 (sorghum-Burgundy bran), and 1.15 mg GAE/g (wheat bran). Adding gold to the NPs decreased phenolic content in all three cases: 2.50 (sorghum-Sumac bran), 1.80 (sorghum-Burgundy bran), and 0.30 (wheat-bran) mg GAE/g. Thus, the synthesis had an impact on the phenolic content. The sizes of the particles were measured using dynamic light scattering: 159 (sorghum-Sumac), 78 (sorghum-Burgundy), and 117 (wheat) nm, respectively. After gold was added, the sizes of the particles changed to 113 (sorghum-Sumac), 115 (sorghum-Burgundy), and 94 (wheat) nm, respectively.

Conclusions

Cereal bran is an eco-friendly source of biopolymers for producing nanoparticles. With its high phenolic content, sorghum bran is ideal for making nanoparticles with various applications. Wheat and sorghum bran is a mill by-product that can be used to synthesize nanoparticles, increasing the value of these agricultural products.

Novelty and Significance

A method was established to develop gold nanoparticles from grain bran. These methods can be used to develop value-added products across many different applications.

高粱麸皮粉与麦麸粉杂交包金谷物颗粒的合成与表征

背景与目的研究不同含酚颗粒膜对纳米颗粒性能的影响。本研究成功地从高粱（漆树和勃艮第）和硬红冬小麦(cv。1863)。三种树皮的酚含量分别为33.40、4.98和1.59 mg GAE/g。麸皮粉的酚类含量分别为6.41（高粱漆皮）、5.31（高粱勃艮第麸皮）和1.15 mg GAE/g（麦麸）。在NPs中添加金降低了三种情况下的酚含量：2.50 mg（高粱-漆树麸），1.80 mg（高粱-勃艮第麸）和0.30 mg（小麦麸）GAE/g。因此，合成对酚含量有影响。采用动态光散射法测定颗粒尺寸：159 nm（高粱-漆树）、78 nm（高粱-勃艮第）和117 nm（小麦）。添加金后，颗粒尺寸分别为113 nm（高粱-漆树）、115 nm（高粱-勃艮第）和94 nm（小麦）。结论谷物麸皮是制备纳米颗粒生物聚合物的环保原料。高粱麸皮酚类物质含量高，是制备具有多种用途的纳米颗粒的理想材料。小麦和高粱麸皮是磨坊的副产品，可以用来合成纳米颗粒，增加这些农产品的价值。建立了以谷糠为原料制备纳米金的新方法。这些方法可用于跨许多不同的应用程序开发增值产品。

期刊介绍： Cereal Chemistry publishes high-quality papers reporting novel research and significant conceptual advances in genetics, biotechnology, composition, processing, and utilization of cereal grains (barley, maize, millet, oats, rice, rye, sorghum, triticale, and wheat), pulses (beans, lentils, peas, etc.), oilseeds, and specialty crops (amaranth, flax, quinoa, etc.). Papers advancing grain science in relation to health, nutrition, pet and animal food, and safety, along with new methodologies, instrumentation, and analysis relating to these areas are welcome, as are research notes and topical review papers. The journal generally does not accept papers that focus on nongrain ingredients, technology of a commercial or proprietary nature, or that confirm previous research without extending knowledge. Papers that describe product development should include discussion of underlying theoretical principles.
