“…Although the S/G ratio of hop bine lignin has not been studied, the ratio of S/G in industrial hemp has been experimentally determined to be 0.64 . A previous study has demonstrated that hop bine delignifies at the same rate as industrial hemp; therefore, we hypothesize that hop bine likely contains a similar S/G ratio …”

“…91 A previous study has demonstrated that hop bine delignifies at the same rate as industrial hemp; therefore, we hypothesize that hop bine likely contains a similar S/G ratio. 92 The color of the hop bine fiber initially was darker, and bleaching of the fibers did not occur as rapidly or to the extent that the UBNSWK proceeded.…”

Ammonium persulfate (APS) mediated oxidation has been used in conjunction with acids under extended reaction times to produce highly crystalline cellulose nanomaterials. Opportunities exist to tailor the surface chemistry and morphological properties of nanocellulose using the economically attractive APS process. Here, the response surface methodology is applied to establish a set of predictable and reproducible guidelines for the synthesis of cellulose nanofibers with specific characteristics. The effect of varying treatment conditions on the APS oxidation of bleached and unbleached wood and non-wood pulps has been assessed by adjusting specifically the APS dosage, oxidation time, and temperature. The surface charge, crystallinity, and aspect ratio of the resulting nanocellulose have been systematically characterized. As-prepared materials exhibited a wide range of carboxylic acid contents on their surface from 0.6 to 1.4 mmol/g, while the crystallinity index changed from 72 to 88%. The morphological characteristics of the cellulose nanofibrils can be varied in the 48–80, 2.7–4.5, and 146–247 nm ranges for the aspect ratio, diameter, and length, respectively. More importantly, the environmentally friendly ammonium persulfate, opposed to TEMPO-mediated oxidation, has been effective at generating similar structural and chemical properties in lignin-containing feedstocks without any pretreatment or adjustment of experimental conditions.

“…Hop products refer primarily to the inflorescences (seed cones) of the female plants of Humulus lupulus L.-belonging to the family of Cannabaceae-which are used in the beer's brewing to provide aroma and flavor; the rest of the plant (bines) are typically discarded. [1][2][3][4][5][6] However, hop bines are rich in lignocellulosic contents and can be used as a source of short fibers. 2,4,6 To date, there are limited reports related to the production or use of hop-derived fiber.…”

“…The use of light-weighted, green, environmentally friendly, and biodegradable fibres as insulating materials provided comparable acoustic properties and thermal resistance with the commercial insulating materials [18]. Hop bine fibres have already been used in the paper industry [19]. The coir-fibre has been used for lightweight vehicle applications [13].…”
