Non-Destructive Assessment of Microbial Spoilage of Broiler Breast Meat Using Structured Illumination Reflectance Imaging with Machine Learning
Food Analytical Methods - - 2024
Meat quality has gained ample attention owing to increased consumer awareness and competition among poultry processors to deliver premium quality products. Nevertheless, chicken breast meat is susceptible to microbial spoilage resulting in economic and product losses. Conventional approaches such as organoleptic, aerobic plate count (APC), and molecular methods have been employed for assessing the...... hiện toàn bộ
Determination of Organochlorine Pesticides in Tea Beverage by Directly Suspended Droplet Microextraction Combined with GC-ECD
Food Analytical Methods - Tập 8 - Trang 147-153 - 2014
In this paper, a simple and efficient directly suspended droplet microextraction (DSDME) method has been developed and optimized, which can be applied on extracting organochlorine pesticides (OCPs) in beverage for gas chromatography–electron capture detector (GC-ECD) analysis. The optimal DSDME was adding 100 μL of isooctane into 5 mL of the beverage sample and stirred for 10 min at 1,000 rpm. The...... hiện toàn bộ
Protein Extraction and Identification by Gel Electrophoresis and Mass Spectrometry from Edible bird’s Nest Samples
Food Analytical Methods - Tập 10 - Trang 387-398 - 2016
Edible bird’s nest (EBN) is a delicacy rich in protein and carbohydrate from the salivary secretion of swiftlets. There are limited studies on the protein profile of EBN, mainly due to its complexity in chemical composition and diversity of species, as well as the capacity of analytical techniques. The protein extraction methods, namely, ultrasonic and detergent (Triton X-100 and SDS)-assisted met...... hiện toàn bộ
Characterization of Volatile Organic Compounds of Vinegars with Novel Electronic Nose System Combined with Multivariate Analysis
Food Analytical Methods - Tập 7 - Trang 1073-1082 - 2013
A novel electronic nose system (also called artificial olfaction system) based on colorimetric sensor array was developed for characterization and identification of the volatile organic compounds (VOCs) of vinegars fermented from different raw materials. Fifteen chemo-responsive dyes including nine metalloporphyrins and six pH indicators were selected according to their sensitivity to volatile com...... hiện toàn bộ
Xác định Spectinomycin trong các sản phẩm chế biến thức ăn và dạng thuốc bằng phương pháp HPLC sử dụng sự chuyển hóa 1-Naphthyl Isocyanate và phát hiện UV Dịch bởi AI
Food Analytical Methods - Tập 9 - Trang 2444-2451 - 2016
Một phương pháp HPLC mới, đơn giản và nhạy cảm đã được phát triển để xác định spectinomycin hydrochloride trong các dạng bào chế và hỗn hợp thức ăn thông qua sự chuyển hóa với 1-naphthyl isocyanate. Việc tách biệt được thực hiện trên cột C18 với pha động bao gồm acetonitril/nước (50:50 v/v, pH 3.2) với tốc độ dòng 1 mL/phút và phát hiện UV tại 230 nm. Các yếu tố ảnh hưởng đến hiệu suất phản ứng ch...... hiện toàn bộ

Fluorescent Detection of 2,4-Dichlorophenoxyacetic Acid in Food Samples Based on Covalent Organic Frameworks and MnO2 Nanosheets
Food Analytical Methods - Tập 13 - Trang 1842-1851 - 2020
2,4-Dichlorophenoxyacetic acid (2,4-D) is a typical chlorinated aromatic herbicide which is widely used because of its low cost. Herein, a new fluorescent assay for 2,4-D is developed based on covalent organic frameworks (COFs) and MnO2 nanosheets. The fluorescence of COFs is quenched effectively by MnO2 nanosheets. Ascorbic acid 2-phosphate (AAP) is hydrolyzed by alkaline phosphatase (ALP) to pro...... hiện toàn bộ
A Review of Current Methods for the Determination of Acrylamide in Food Products
Food Analytical Methods - Tập 5 - Trang 29-39 - 2011
Acrylamide (AA) is a potentially carcinogenic substance which is formed during heating of food products containing carbohydrates and asparagine. It was first detected in food products in 2002. Since that time, several analytical methods have been made available for the quantification of AA in various foods. Starting from the announcement in 2002, occurrence, formation, chemistry, toxicology, and p...... hiện toàn bộ
Validation of the Methods for the Non-Milk Fat Detection in Artificially Adulterated Milk with Palm OilAbstract Dairy products are among the most adulterated food products. Due to the current high price of milk fat, it has been replaced by low-cost oils, especially those oils that have the same fatty acid profile as milk fat. This study intends to confirm the lowest level of palm oil added to milk and validate various methods for detecting palm oil in milk, including... ... hiện toàn bộ
