“…The turbidity of chicken soup grew gradually with the increase in ultrasonic power, in the treatment group of 840 W reached the maximum value. The increase in turbidity of chicken broth may be due to the looseness of the internal structure of chicken meat caused by the increase in ultrasonic treatment power so that substances are constantly released into the chicken broth during the stewing process (Suresh et al ., 2020).…”

SummaryThe chicken broth was pre‐treated with ultrasound at 0, 480, 600, 720 and 840 W for 30 min before stewing, and the changes of free fatty acids, small molecular compounds, volatile flavour compounds, umami polypeptides in the chicken broth were determined by GC–MS, UPLC‐Q‐Exactive‐MS, GC–IMS and LC–MS/MS, respectively. 600 W ultrasonic treatment group outperformed the other groups in terms of sensory evaluation (P < 0.05). Palmitic acid and stearic acid were the chief free fatty acids in chicken broth. 530 and 236 small molecule metabolites were found. 36 volatile compounds were identified in chicken broth, mainly aldehydes. The proportion of sweet and umami amino acids in the chicken broth of the 600 W ultrasonic treatment group accounted for 63% of the total polypeptide sequence, indicating that pre‐ultrasonication can increase the content of sweet and umami polypeptides in chicken soup. The overall taste and flavour of Wuding chicken soup under pre‐ultrasonication with 600 W power were the best combined with sensory evaluation scores. These results can provide scientific and theoretical guidance for the further understanding of the effect of ultrasound assistance on the quality of chicken broth and the intensive processing of local chicken.

“…However, there is scant literature on the ultrasound-assisted production of bioethanol from food waste. Suresh et al [ 177 ] reported that ultrasound pre-treatment at 340 W could improve the yield of bioethanol from potato waste after fermentation to 54.1 g/L. In addition, ultrasound-combined HCl was more efficient in the enhancement of bio-ethanol as compared with ultrasound-combined enzyme pre-treatment.…”

Ultrasonic processing has a great potential to transform waste from the food and agriculture industry into value-added products. In this review article, we discuss the use of ultrasound for the valorisation of food and agricultural waste. Ultrasonic processing is considered a green technology as compared to the conventional chemical extraction/processing methods. The influence of ultrasound pre-treatment on the soluble chemical oxygen demand (SCOD), particle size, and cell wall content of food waste is first discussed. The use of ultrasonic processing to produce/extract bioactives such as oil, polyphenolic, polysaccharides, fatty acids, organic acids, protein, lipids, and enzymes is highlighted. Moreover, ultrasonic processing in bioenergy production from food waste such as green methane, hydrogen, biodiesel, and ethanol through anaerobic digestion is also reviewed. The conversion of waste oils into biofuels with the use of ultrasound is presented. The latest developments and future prospective on the use of ultrasound in developing energy-efficient methods to convert food and agricultural waste into value-added products are summarised.

“…The monosaccharides are utilized as a feedstock for the fermentation process for making bioethanol. The most common acids used for hydrolysis are sulfuric acid, phosphoric acid, and hydrochloric acid [ 97 , 98 , 99 ]. The advantage of acid hydrolysis for producing sugar in the bioethanol process is that the acid can easily access the cell wall.…”

The increasing demand for petroleum-based polyethylene terephthalate (PET) grows population impacts daily. A greener and more sustainable raw material, lignocellulose, is a promising replacement of petroleum-based raw materials to convert into bio-PET. This paper reviews the recent development of lignocellulose conversion into bio-PET through bioethanol reaction pathways. This review addresses lignocellulose properties, bioethanol production processes, separation processes of bioethanol, and the production of bio–terephthalic acid and bio–polyethylene terephthalate. The article also discusses the current industries that manufacture alcohol-based raw materials for bio-PET or bio-PET products. In the future, the production of bio-PET from biomass will increase due to the scarcity of petroleum-based raw materials.
