Abstract

The bioactive potential of plant organ powders depends on their bioactive compound content and is influenced by the properties of particle size fractions (PSFs). This study evaluated the effects of PSFs on total polyphenols, flavonoids, and condensed tannins in plant organ powders and compared them with those of unsieved powders (UnPs). Young (YLDE) and mature (MLDE) leaves, bark (BDE) of Dacryodes edulis, Solanum torvum leaves (LST), and Curcuma longa rhizome (RCL) were collected and processed into powders (Ø ≤ 1000 μm sieve, AFNOR brand). These powders were then divided into two batches, one of which was separated into fractions of different sizes. The total polyphenols, flavonoids, and condensed tannin contents were determined. UnP and seven PSFs were obtained, with the 250–400 μm fraction being the most abundant. The UnP of RCL, YLDE, and LST had the highest contents of total polyphenols (303.70 ± 1.66 mg GAE/100 g DM), flavonoids (218.19 ± 1.93 mg QE/100 g DM), and condensed tannins (19.16 ± 0.29 mg CE/100 g DM), respectively. The contents of these bioactive compounds were higher in the < 125 μm fraction. The extraction of total polyphenols and flavonoids from UnP exceeded the sum of PSFs, whereas the condensed tannins were higher in the sum of PSFs for YLDE, MLDE, and BDE. For LST and RCL, the extracts of the three compounds from UnP and the sum of the PSFs were equal. The powder fractioning method was advantageous for the extraction of condensed tannins from the YLDE, MLDE, and BDE.

Dacryodes edulis、Solanum torvum 和 Curcuma longa 植物器官粉末和粒径馏分的生物活性潜力比较评估

植物器官粉末的生物活性潜力取决于其生物活性化合物的含量，并受粒度馏分（PSFs）特性的影响。本研究评估了 PSFs 对植物器官粉中总多酚、类黄酮和缩合单宁的影响，并与未松散粉末（UnPs）进行了比较。收集并加工 Dacryodes edulis、Solanum torvum leaves (LST) 和 Curcuma longa rhizome (RCL) 的嫩叶（YLDE）和成熟叶（MLDE）、树皮（BDE），并将其制成粉末（Ø ≤ 1000 μm 筛，AFNOR 品牌）。然后将这些粉末分成两批，其中一批分成不同大小的馏分。测定总多酚、类黄酮和缩合单宁的含量。得到了 UnP 和七个 PSF，其中 250-400 μm 的馏分含量最高。在 RCL、YLDE 和 LST 的 UnP 中，总多酚（303.70 ± 1.66 mg GAE/100 g DM）、黄酮类化合物（218.19 ± 1.93 mg QE/100 g DM）和缩合单宁（19.16 ± 0.29 mg CE/100 g DM）的含量分别最高。在 125 μm 的馏分中，这些生物活性化合物的含量较高。从 UnP 中提取的总多酚和类黄酮超过了 PSFs 的总和，而 YLDE、MLDE 和 BDE 中的缩合单宁则高于 PSFs 的总和。就 LST 和 RCL 而言，从 UnP 中提取的三种化合物与 PSF 的总和相等。粉末分馏法有利于从 YLDE、MLDE 和 BDE 中提取缩合单宁。

期刊介绍： The journal presents readers with the latest research, knowledge, emerging technologies, and advances in food processing and preservation. Encompassing chemical, physical, quality, and engineering properties of food materials, the Journal of Food Processing and Preservation provides a balance between fundamental chemistry and engineering principles and applicable food processing and preservation technologies. This is the only journal dedicated to publishing both fundamental and applied research relating to food processing and preservation, benefiting the research, commercial, and industrial communities. It publishes research articles directed at the safe preservation and successful consumer acceptance of unique, innovative, non-traditional international or domestic foods. In addition, the journal features important discussions of current economic and regulatory policies and their effects on the safe and quality processing and preservation of a wide array of foods.
