Abstract
Mycotoxins, as secondary metabolites produced by fungi, have been the focus of researchers in various countries and are considered to be one of the major risk factors in agricultural products. There is an urgent need for a rapid, simple and high-performance method to detect residues of harmful mycotoxins in agricultural foods. We have developed a gold nanoparticle-based multiplexed immunochromatographic strip biosensor that can simultaneously detect fifteen mycotoxins in cereal samples. With this optimized procedure, five representative mycotoxins, deoxynivalenol (DON), zearalenone (ZEN), T-2 toxin (T-2), tenuazonic acid (TEA) and alternariol (AOH) were detected in the range of 0.91-4.77, 0.04-0.56, 0.11-0.68, 0.12-1.02 and 0.09-0.75 ng/mL, respectively. The accuracy and stability of these measurements were demonstrated by analysis of spiked samples with recoveries of 91.8%-115.3% and coefficients of variation <8.7%. In addition, commercially available samples of real cereals were tested using the strips and showed good agreement with the results verified by LC-MS/MS. Therefore, Our assembled ICA strips can be used for the simultaneous detection of 5 mycotoxins and their analogs (15 mycotoxins in total) in grain samples, and the results were consistent between different types of cereal foods, this multiplexed immunochromatographic strip biosensor can be used as an effective tool for the primary screening of mycotoxin residues in agricultural products.

Embracing nutritional, physical, pasting, textural, sensory and phenolic profile of functional muffins prepared by partial incorporation of lyophilized wheatgrass, fenugreek and basil microgreens juice powder. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:4286-4295. [PMID: 38308402 DOI: 10.1002/jsfa.13314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 12/14/2023] [Accepted: 01/16/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND Muffins are delightful baked food products that have earned a prominent place in the daily diet of a majority of people around the world. The incorporation of microgreens juice powder (MJP) into muffins boosts their nutritional value. The influence of the incorporation of wheatgrass, fenugreek and basil MJP at 1.5% and 3.0% levels on the nutritional composition, physical properties, pasting, sensory, textural and phenolic profile of functional muffins was evaluated. RESULTS The results indicated a significant increase in the protein content, ash content, dietary fiber and total phenolic content of MJP incorporated muffins. The incorporation of MJP to the muffins led to a gradual reduction in the L*, a* and b* values. Baking characteristic such as bake loss decreased significantly as a result of MJP incorporation. Furthermore, the incorporation of various MJPs resulted in a significant decrease in the peak viscosity of the flour-MJP blends. Regarding texture, the hardness and chewiness of the muffins increased progressively with an increase in the level of MJP incorporation. The highest hardness (10.15 N) and chewiness (24.45 mJ) were noted for 3% fenugreek MJP incorporated muffins (FK 3.0). The sensory score of MJP incorporated muffins was acceptable and satisfactory. Additionally, 3% basil MJP incorporated muffins (BL 3.0) marked the dominant presence of majority of the detected phenolic acids such as ferulic acid, sinapic acid, chlorogenic acid, caffeic acid, quercetin, cinnamic acid, isothymosin and rosamarinic acid. The highest concentration of p-coumaric acid (11.95 mg kg-1), vanillic acid (26.07 mg kg-1) and kaempferol (8.04 mg kg-1) was recorded for FK 3.0 muffin. CONCLUSION MJP incorporated muffins revealed the pool of phenolic acids and the reduced bake loss is of industrial interest. The present study concludes that wheatgrass, fenugreek and basil MJP can be incorporated by up to 3% into baked products as a source of functional ingredients for health benefits. © 2024 Society of Chemical Industry.
