Abstract:

The levels of free and total gossypol and the raw nutrient content (crude protein, crude oil, dry matter, crude ash, neutral detergent fiber, and acid detergent fiber) in cottonseed meals that are produced in Southeastern Anatolia were determined in the present study. Gossypol and raw nutrient content analyses were carried out by using the cottonseed meal samples obtained from 12 different cottonseed oil factories located in Diyarbakır, Şanlıurfa, Adıyaman, Batman, Mardin, and Gaziantep. As a result of the present study, free gossypol levels in the cottonseed meal samples were 1937, 1878, 1916

Abstract:

Use of cottonseed as protein source for food application and monogastric animals are restricted due to the presence of polyphenolic toxic content known as gossypol. Reduction of gossypol and improving crude protein content in cottonseed flour may increase its utility for feed and food industries. The present study aims to analyze the influence of three individual methods viz., sprouting method, enzymatic method and solvents method on free and total gossypol content, crude protein content, oil content and flour yield.

This study was conducted to determine the gossypol content in Bt cottonseed (Seeni-1) oil by using Fourier Transform Infrared (FTIR) spectroscopy with an Attenuated Total Reflectance (ATR) element. The wavelengths used were selected by spiking refined, bleached deodorized palm oil (RBDPO) to gossypol concentrations of 0-5% and noting the regions of maximal absorbance. Absorbance values of the wavelength regions 3700-2400 & 1900-750 cm-1 and a partial least squares (PLS) method were used to derive calibration models for Hamid cottonseed oil, Seeni-1 cottonseed oil, and gossypol-spiked RBDPO

Abstract:

Cottonseed is one of the important by-products of the cotton crop. Researchers claim that cottonseed with less than 0.45% of gossypol is quite good for human consumption and animal feeding because it is a rich source of protein, edible oil, and energy. Total and free gossypols are the influencing parameters that reduce the edible nature of the cottonseed. In the present work, multiple quadratic regression models have been prepared to predict the reduction in the free and total gossypol percent. This response surface method (RSM)-based approach was applied to investigate the combined effect bet

Abstract:

Gossypol is a complex plant polyphenol reported to be cytotoxic and anti-inflammatory, but little is known about its effect on gene expression in macrophages. The objective of this study was to explore gossypol’s toxicity and its effect on gene expression involved in the inflammatory response, glucose transport and insulin signaling pathways in mouse macrophages. Mouse RAW264.7 macrophages were treated with multiple concentrations of gossypol for 2–24 h. Gossypol toxicity was estimated by MTT assay and soluble protein content. qPCR analyzed the expression of anti-inflammatory tristetraprolin f

Abstract:

Kinetics and thermodynamics of gossypol extraction from defatted cottonseed meal by ethanol Gossypol is polyphenolic aldehyde, a toxic substance naturally present in cotton plant to protect it from insects, pests and diseases. Maximum gossypol is concentrated in the seed. After extraction of oil from the cottonseed, the defatted cottonseed meal which contains both the gossypol and proteinous matter is left behind. A number of attempts have been made using different solvents to extract gossypol from the seeds. However, all these efforts have remained in the realm of academic activity only as no

Abstract A liquid chromatographic method has been developed for the determination of unbound and acetone- soluble bound gossypol in cottonseed meals and mixed feeds at levels of 0.5 ppm. The method involves extraction with aqueous acetone in the presence of ascorbic acid, hydrolysis of the "soluble bound" forms with hydrochloric acid, partitioning into chloroform, and chromatographic separation on a 10 µm C18 column by step gradient elution using a methanol-water mobile phase acidified with phosphoric acid. With minor modifications, the method permitted discriminate determination of unbound go

Abstract:

Tetraploid cultivated cotton (Gossypium spp.) produces cottonseeds rich in protein and oil. Gossypol and related terpenoids, stored in the pigment glands of cottonseeds, are toxic to human beings and monogastric animals. However, a comprehensive understanding of the genetic basis of gossypol and gland formation is still lacking. We performed a comprehensive transcriptome analysis of four glanded versus two glandless tetraploid cultivars distributed in Gossypium hirsutum and Gossypium barbadense.

Successful breeding programs optimize time and resources to produce elite lines. Selecting individual plants in the F2 generation is an efficient strategy if the trait is highly heritable and nondestructive methods exist to analyze the seed. Cotton (Gossypium hirsutum L.) seed has limited uses because of gossypol, a toxic compound found in the seed. Gossypol exists in two enantiomeric forms with the (+) less toxic than the (−) form. Reducing gossypol or increasing the (+) enantiomer in the seed would increase the amount that could be fed to livestock, chicken, or fish. Rapid, cost-effective me
