“…The spectra are given in Figure 1 . The IR spectra of various cotton-related materials have been previously reported (e.g., [ 23 , 43 , 44 , 45 ]). The ATR spectrum of the CSM surface ( Figure 1 , top spectrum) showed a strong and broad band at 3700–3000 cm −1 due to the O-H and N-H stretching in carbohydrates, glycerol, adsorbed water, and protein.…”

Poly(lactic acid) (PLA) is a common biobased film-former made from renewable biomass, such as polysaccharides from sugarcane, corn, or cassava. It has good physical properties but is relatively expensive when compared to the plastics used for food packaging. In this work, bilayer films were designed, incorporating a PLA layer and a layer of washed cottonseed meal (CSM), an inexpensive agro-based raw material from cotton manufacturing, where the main component is cottonseed protein. These bilayer films were made through the solvent casting method. The combined thickness of the PLA/CSM bilayer film was between 47 and 83 μm. The thickness of the PLA layer in this film was 10%, 30%, or 50% of the total bilayer film’s thickness. Mechanical properties of the films, opacity, water vapor permeation, and thermal properties were evaluated. Since PLA and CSM are both agro-based, sustainable, and biodegradable, the bilayer film may be used as an eco-friendlier food packaging material, which helps reduce the environmental problems of plastic waste and microplastics. Moreover, the utilization of cottonseed meal may add value to this cotton byproduct and provide a potential economic benefit to cotton farmers.

“…ATR–FTIR analysis has been used in cotton biomass characterization [ 35 , 36 , 37 ]. The ATR–FTIR spectra of the oil extracts of the cottonseed butters ( Figure 2 ) were typical to those of cottonseed and other vegetable oil samples in the literature [ 7 , 35 , 38 ]. The four major peaks were found at 2924, 2854, 1744, and 1160 cm −1 .…”

Cottonseed is a natural product of cotton (Gossypium spp.) crops. This work evaluated the oxidative stability of cottonseed butters through accelerated autoxidation by storage at 60 °C for 25 days. Three oxidative stability parameter values (peroxide value, p-anisidine value, and total oxidation value) were monitored over the storage time. These chemical measurements revealed that the storage stability of the butter products was dominated by primary oxidation of lipid (oil) components, while the secondary oxidation levels were relatively unchanged over the storage time. An analysis of the tocopherols (natural oxidants in cottonseed) suggested not only the protection function of the molecules against oxidation of the cottonseed butter during storage, but also the dynamic mechanism against the primary oxidation of lipid components. Attenuated total reflectance–Fourier-transform infrared spectroscopy (ATR–FTIR) data confirmed no changes in the major C functional groups of cottonseed butters over the storage time. On the other hand, characteristic minor peaks of conjugated dienes and trienes related to lipid oxidation were impacted by the accelerated storage. As each day of accelerated oxidation at 60 °C is equivalent to 16 days of storage at 20 °C, observations in this work should have reflected the oxidative stability behaviors of the cottonseed butters after about 13 months of shelf storage under ambient storage conditions. Thus, these data that were collected under the accelerated oxidation testing would be useful not only to create a better understanding of the autooxidation mechanism of lipid molecules in cottonseed butters, but also in developing or recommending appropriate storage conditions for cottonseed end products to prevent them from quality degradation.

“…The authors also demonstrated that the RS approach was as accurate as near‐infrared analysis. Currently, there are only limited reports on RS characterization of fiber and cottonseed research (Cabrales et al., 2014; da Mata et al., 2022) even though various IR techniques have been applied into a wide array of cotton biomass characterization (He & Liu, 2021; He, Liu et al., 2022; Liu et al., 2016).…”

“…Like infrared spectroscopy (IR), Raman spectroscopy (RS) is a vibrational spectroscopic technique. While IR is an excellent tool for structural and quantitative analysis of natural products (Di Meo et al., 2022; He & Liu, 2021; He & Ohno, 2012), RS is able to provide some additional structural information due to the different detection mechanisms (Johnston & Aochi, 1996; Makarem et al., 2019). For example, unlike IR, RS is a good technique for analyzing alkyl chains since the C─C and C─H bonding can be determined in the presence of water (Özgenç et al., 2017).…”

Raman spectroscopy (RS) is a vibrational spectroscopy. This work reported the RS spectral characteristics of fiber and seed of six cotton (Gossypium sp.) genotypes differing in fiber length. While the RS spectra of fiber samples were dominated by the cellulose-related peaks, the spectra of cottonseed samples were featured by the bands related to oil, protein, carbohydrate, and lignin components. Principal component analysis (PCA) revealed that the first two principal components (PCs) accounted for >87% of the total variation of the two types of samples. The PC1 versus PC2 plot classified the six fiber samples into three groups, but their cottonseeds into four groups. This experimental evidence implied the possibility of RS combined with PCA for rapid fiber phenotyping of cotton as well as for evaluating cottonseed nutrient information.
