Abstract
Coffee silverskin (CS), a by-product of the coffee roasting process, has high protein content (16.2-19.0%, w/w), making it a potential source for plant protein and bioactive peptide production. This study aims to develop innovative extraction methods for phenolic compounds and proteins from CS. The conditions for hydrothermal (HT) extraction of phenolic compounds from CS were optimized by varying CS loading (2.5-10%, w/v), temperature (110-130 °C), and time (5-30 min) using a one-factor-at-a-time (OFAT) approach. The highest TPC of 55.59 ± 0.12 µmole GAE/g CS was achieved at 5.0% (w/v) CS loading and autoclaving at 125 °C for 25 min. Following hydrothermal extraction, CS protein was extracted from HT-extracted solid fraction by microwave-assisted alkaline extraction (MAE) using 0.2 M NaOH at 90 W for 2 min, resulting in a protein recovery of 12.19 ± 0.39 mg/g CS. The CS protein was then subjected to enzymatic hydrolysis using protease from Bacillus halodurans SE5 (protease_SE5). Protease_SE5-derived CS protein hydrolysate had a peptide concentration of 0.73 ± 0.09 mg/mL, with ABTS, DPPH, and FRAP values of 15.71 ± 0.10, 16.63 ± 0.061, and 6.48 ± 0.01 µmole TE/mL, respectively. Peptide identification by LC-MS/MS revealed several promising biological activities without toxicity or allergenicity concerns. This study's integrated approach offers a sustainable and efficient method for extracting valuable compounds from CS, with potential applications in the food and pharmaceutical industries.

Abstract
The increasing population, food demand, waste management concerns, and the search for sustainable alternatives to plastic polymers have led researchers to explore the potential of waste materials. This study focused on a waste of pine nut processing referred to in this paper as pine nut skin. For the first time, its nutritional profile, potential bioactive peptide, contaminants, and morphological structure were assessed. Pine nut skin was composed mainly of carbohydrates (56.2%) and fiber (27.5%). The fat (9.8%) was about 45%, 35%, and 20% saturated, monounsaturated, and polyunsaturated fatty acid, respectively, and Omega-9,-6, and -3 were detected. Notably, oleic acid, known for its health benefits, was found in significant quantities, resembling its presence in pine nut oil. The presence of bioactive compounds such as eicosapentaenoic acid (EPA) and phytosterols further adds to its nutritional value. Some essential elements were reported, whereas most of the contaminants such as heavy metals, polycyclic aromatic hydrocarbons, rare earth elements, and pesticides were below the limit of quantification. Furthermore, the in silico analysis showed the occurrence of potential precursor peptides of bioactive compounds, indicating health-promoting attributes. Lastly, the morphological structural characterization of the pine nut skin was followed by Fourier Transform Infrared and solid-state NMR spectroscopy to identify the major components, such as lignin, cellulose, and hemicellulose. The thermostability of the pine nut skin was monitored via thermogravimetric analysis, and the surface of the integument was analyzed via scanning electron microscopy and volumetric nitrogen adsorption. This information provides a more comprehensive view of the potential uses of pine nut skin as a filler material for biocomposite materials. A full characterization of the by-products of the food chain is essential for their more appropriate reuse.

Abstract
Dietary fiber (DF) significantly affects the quality attributes of food matrices. Depending on its chemical composition, molecular structure, and degree of hydration, the behavior of DF may differ. Numerous reports confirm that incorporating DF derived from food waste into food products has significant effects on textural, sensory, rheological, and antimicrobial properties. Additionally, the characteristics of DF, modification techniques (chemical, enzymatic, mechanical, thermal), and processing conditions (temperature, pH, ionic strength), as well as the presence of other components, can profoundly affect the functionalities of DF. This review aims to describe the interactions between DF and water, focusing on the effects of free water, freezing-bound water, and unfreezing-bound water on the hydration capacity of both soluble and insoluble DF. The review also explores how the structural, functional, and environmental properties of DF contribute to its hydration capacity. It becomes evident that the interactions between DF and water, and their effects on the rheological properties of food matrices, are complex and multifaceted subjects, offering both opportunities and challenges for further exploration. Utilizing DF extracted from food waste exhibits promise as a sustainable and viable strategy for the food industry to create nutritious and high-value-added products, while concurrently reducing reliance on primary virgin resources.

Abstract
The aim of the research is to investigate whether purchasing decisions about bakery products (bread, snacks and biscuits) are influenced by concerns about health, climate change, biodiversity loss and food waste. The exploratory survey was carried out in two successive moments before and during the health emergency from COVID-19. Before the health emergency, face-to-face interviews were carried out using a structured questionnaire. Data were analyzed by factor analysis, reliability tests and descriptive analysis. Structural equation modeling (SEM) was employed to test the research hypotheses. The results of the modeling analysis of the structural equations highlighted that health and the environment represent an important background in the consumer experience of the respondents and influence the attitude and intention to purchase safe and environmentally friendly bakery products. Furthermore, the results suggest that informed, modern and aware consumers have direct and indirect effects on the intentions to adopt sustainable attitudes. On the contrary, the perception relating to the shops where consumers buy bakery products does not always show a significant influence on the propensity for sustainability. During the health emergency, the interviews were conducted online. Families confined to their homes, buying less in stores, have prepared many baked goods manually at home. The descriptive analysis of this group of consumers shows a growing attention to points of sale and the tendency to use online shopping. Furthermore, the changes in the type of purchases and the importance attributed to the need to reduce food waste emerge.

Abstract
BACKGROUND Papaya leftovers are a good source of dietary fiber (DF) and antioxidants. They can be transformed in dietary fiber concentrates (DFCs) to be used as ingredients in food formulation, improving consumers' health status. RESULTS Using the peel or the pulp of papaya, DFCs were produced. These DFCs were used in muffin production. Muffins produced with 7.7% DFCs and 47.6 g water had the same specific volume (2.0 cm3 g-1 ) but softer crumb than those obtained with a reference formulation without DF addition, showing average hardness of 15 N. In general, the addition of DFCs of pulp or peel slightly affected other textural profile parameters. Also, non-significant differences were observed for muffins containing pulp or peel DFCs, which showed average values of 10.9 N for chewiness, 0.95 for springiness, 0.76 for cohesiveness and 0.42 for resilience. Regarding the crumb structure, muffins with pulp DFCs showed the lowest value for d3.2 (1.3 ± 0.3 mm). Meanwhile, the highest anti-radical and reducing capacity, 240 ± 2 and 1050 ± 6 mgeq Trolox g-1 muffin (dry basis), respectively, were observed in the muffins with peel DFC. Finally, the addition of DFCs allowed us to maintain lower hardness values than those of the reference formulation during the whole storage period studied (22 days). Muffins with peel DFCs tended to have a lower rate of crumb hardening (0.08 ± 0.02) d-1 . CONCLUSION The addition of papaya DFCs to muffin formulations confers interesting properties for industry and consumers, providing functionality, extending the shelf life as well as transforming papaya leftovers in new functional ingredients, contributing to a circular economy. © 2022 Society of Chemical Industry.
