“…With respect to onions, although there has been substantial evidence for the usefulness of extracts, deriving mainly from the outer inedible layers, as antioxidants (Kefalas and Makris 2006;Škerget et al 2009), antibrowning (Lee 2007;Roldán et al 2008) and colouring agents (Guinot et al 2007), no study up to date provided any information on the stability of the major components accounting for the aforementioned properties.…”

Onion solid wastes were analysed using HPLC and LC / MS and the major polyphenols detected were quercetin, quercetin 4′-O-glucoside, accompanied by protocatechuic acid and a benzofuranone derivative. The latter two compounds have been demonstrated as some of the degradation products that might arise as a result of peroxidase-mediated decomposition of quercetin. These four substances, along with two principal enzymes implicated in flavonols breakdown, β-glycosidase and peroxidise, were monitored throughout an examination period of 48 h, in ground onion solid waste. The determinations showed that quercetin 4′-O-glucoside content increased by 13.3%, while quercetin, benzofuranone derivative and protocatechuic acid contents increased by 68.6, 37.5 and 58.4%, respectively. β-Glycosidase activity exhibited fluctuations and increased by 38.2%, whereas the POD showed a constant increasing trend, leading in 21.7% higher activity. On such a ground, a hypothesis was set up to explain transformations of flavonols.

“…After long exposure to UV rays as well as several washing steps, this protection might be reduced or even lost. Otaviano et al [43] reported a good UPF (25) for cotton dyed with pomegranate peel extract, but after 10 washing cycles, no UV protection was detected. To address this issue, mordants can be used.…”

“…The biological properties of the different types of phenolic compounds make them an extremely interesting group of compounds with potential for use in the textile industry. Beyond their natural coloration ability, these compounds have also been investigated for their potential to impart novel functionalities to textiles, including antimicrobial, antioxidant, ultraviolet (UV) protection, and flame retardance properties, among others [24][25][26][27]. As such, a literature research methodology was completed using the databases Science Direct and Web of Science, and research articles reporting natural dyes containing phenolic compounds applied to textile fabrics were compiled and investigated further.…”

Textile dyeing is known to have major environmental concerns, especially with the high use of toxic chemicals. The use of alternatives such as natural dyes rich in phenolic compounds has become extremely appealing in order to move towards a more sustainable circular economy. Phenolic dyes have the potential to functionalize textile fabrics with properties such as antimicrobial, antioxidant, and UV protection. Wastes/residues from the agri-food industries stand out as highly attractive sources of these compounds, with several by-products showing promising results in textile dyeing through the implementation of more sustainable and eco-friendly processes. This review presents an up-to-date exploration of the sources of phenolic compounds used in the textile industry over the past two decades, with a primary focus on the functional properties they provide to different fabrics. The research highlights a surge in interest in this theme since 2017, accentuating a noticeable upward trend. Throughout this review, emphasis is given to by-products from the agri-food industry as the sources of these compounds. The reviewed papers lay the foundation for future research, paving the way for exploring the potential of raw materials and by-products in the creation of functional and smart textiles.

ÖZET: Bu çalışmada, % 100 yünlü kumaş, nane (Mentha spicata L.) ve kekik (Thymus vulgaris L.) bitki kaynakları kullanarak doğal olarak boyanmıştır. Boyama işleminden önce yünlü kumaşlar demir(II) sülfat ile ön mordanlama yöntemine göre farklı konsantrasyonlarda mordanlanmıştır. Doğal boyama işleminden sonra renkli kumaşların K/S renk verimi, CIE L * a * b * renk koordinatları ve çeşitli haslık testleri ile renk kalitesi belirlenmiştir.Anahtar Kelimeler: Yün, doğal boyama, K/S renk verimi, haslık NATURAL DYEING OF WOOL FIBER USING MINT (Mentha spicata L.) AND THYME (Thymus vulgaris L.)ABSTRACT: In this study, 100% wool fabrics were naturally dyed using mint (Mentha spicata L.) and thyme (Thymus vulgaris L.). Before the dyeing process, fabrics were mordanted with iron (II) sulfate with different concentrations according to pre-mordanting technique. After the natural dyeing process, K/S color yields, CIE L * a * b * color coordinates and various fastness properties of dyed fabrics were determined.
