Simplified process of extraction of polyphenols from agroindustrial grape waste

Optimization of blending ratios in asparagus-lemon juice using response surface methodology

“…It is generally assumed that the degradation of AA follows first-order kinetics in most biological materials of the food system. The loss of AA in the blended juice was calculated by using the first-order reaction given below (Equation 1) (Chani-Paucar et al, 2021):…”

Geolashon (Teloschistes flavicans), a natural yellow dye from the Peruvian Andes: traditional uses, bioactive extraction, and potential applications

“…The color changes of intelligent packaging formulated with natural pigments are capable of evidencing the state of the useful life of the food product and biodegradable packaging (Latos-Brozio & Masek, 2020). The new applications of natural colorings represent a horizon of opportunities for the healthiest and most eco-sustainable food industry.Another aspect of applying dyes in food is using healthier colorants and pigments (He et al, 2021;Latos-Brozio & Masek, 2020) and producing sustainably with environmental responsibility through the use of waste agro-industrial (Chañi-Paucar et al, 2020;Toledo-Merma et al, 2022). Recently, to incorporate healthier dyes in commonly consumed food products, pre-neutralized crude palm oil has been included as a source of yellow/orange colorant (carotenoids) for the preparation of fish sausages (Chaijan & Panpipat, 2021), anthocyanins extracted from Ficus carica peels and Prunus spinosa fruit for confectionery products (Backes et al, 2020) and yellow/orange prickly pear pulp microparticles as a source of coloring for yogurt (Carmona et al, 2021).…”

“…The processing of new raw materials, and sources of natural pigments, demands the design and optimization of adequate processes to obtain quality products with a good, helpful life that allows their distribution, commercialization, and subsequent consumption. The useful life of products made with natural products, such as natural colorants, has been the subject of various studies to improve their stability as a pure additive and in derivatives, which may contribute to extending their useful life (Bocker & Silva, 2022;Carmona et al, 2021;Chañi-Paucar et al, 2020;Miranda et al, 2021;Nirmal et al, 2021;Sampaio et al, 2021;Sun et al, 2023). Another important aspect of using new raw materials in the industry is their relevance of use, that is, how safe is the use of natural raw materials and their derivatives in daily consumer products, such as food and cosmetics?…”

“…The toxicity of the solvents used in conventional methods limits the use of bioactive extracts. On the other hand, GRAS solvents can be used in conventional methods; with proper optimization of the process, a suitable extraction yield can be obtained, but stability and its application may be limited without prior stabilization of the bioactive(Chañi-Paucar et al, 2020). Emerging technologies are available for the production of bioactive compounds in a more efficient and eco-friendly way(Lao et al, 2020).…”

Optimal preparation time in the vermicompost production process

“…Inadequate preparation time can disrupt the process and increase the time required to obtain vermicompost, eliminating worms, reducing the quality of the resulting fertilizer, and unnecessary occupation of space during preparation. Therefore, determining the appropriate duration of this preparation is effective and important in optimizing the vermicompost process (Chañi-Paucar et al, 2021). Therefore, in this paper, the effect of different preparation times on the speed of the process (speed of fertilizer) and the quality of the resulting fertilizer in terms of carbon (C), nitrogen (N), pH, and C/N ratio for 40 days in the vermicomposting process was investigated.…”
