This review discusses the potential of emerging technologies, as well their integration with conventional methods, to optimize extraction lignocellulosic compounds from cocoa pod hull (CPH), an agro-industrial residue that represents approximately 76% total weight fruit. CPH is primarily composed cellulose, hemicellulose, lignin, and pectin. Emerging technologies such microwave-assisted extraction, hydrothermal treatment, subcritical water, ionic liquids, deep eutectic solvents, ultrasound...

In order to obtain a highly nutritious extrudate, combination of pseudocereals, vegetable protein, and banana flour, fruit with high sensory acceptability, was used. The objective the research produce multi-component extrudate (ME) based on cañihua quinoa addition pea protein isolate flour. response variables evaluated were composition, expansion, hydration, colour, hardness properties, as well microscopy characteristics flakes produced. These compared three commercial extrudates,...

Mauritia flexuosa L.f. is a palm tree which presents great morphological variability (morphotypes), represented mainly by the mesocarp color of its fruits. The objective study was to characterize physicochemical and antioxidant properties three morphotypes ("Yellow", "Colour" "Shambo") greater economic importance in Peruvian Amazon. "Shambo" showed significantly high content bioactive compounds (total phenolics, flavonoids carotenoids) DPPH radical scavenging activity compared "Yellow" (p ≤...

Mauritia flexuosa L.f. is a palm from the Amazon. Pulp and oil are extracted its fruits, with high content of bioactive compounds. This study presents economic evaluation two extraction processes: (a) Conventional solvent (CSE) 80% ethanol for recovery phenolic-rich extracts; (b) Supercritical fluid (SFE) followed by CSE to obtain extracts. The objective this was compare feasibility both processes. sensitivity were evaluated using SuperPro Designer 9.0® software at an volume 2000 L. Similar...

Supercritical fluids' extraction (SFE) and conventional solvent (CSE) for defatting of quinoa flour as pretreatments to produce the protein hydrolysate (QPH) were studied. The objective was extract oil separate phenolic compounds (PC) defatted subsequent enzymatic hydrolysis. yield (OEY), total flavonoid content (TFC), QPH compared. SuperPro Designer 9.0® software used estimate cost manufacturing (COM), productivity, net present value (NPV) on laboratory industrial scales. SFE allows higher...

Applications of formulations that incorporate emulsified oils offer interesting prospects for producing foods with better characteristics are in line the new trends healthy eating and regulations on nutritional claims. This review defines classifies types emulsions according to their drop size, formulation analyzes latest research related application food industry. It presents valuable information use micro, nano macro preparation meat, dairy vegetable products as a potential alternative...

The conventional method of employing low temperatures for storage and distribution has long been the standard approach preserving most fruits vegetables. This practice is likewise prevalent in retail industry, which relies on similar methods transporting maintaining quality perishable products their shelves. aim was to preserve bananas (Musa paradisiaca) using an ethylene scavenger, potassium permanganate, contained small paper bags, increase time at cost. were distributed four plastic...

The objective of the research was to produce biogas by anaerobic co-digestion biomass and urban solid waste, which made it possible take advantage these organic wastes, transforming them into a renewable energy source such as being fuel with an high calorific on average 19.6 25 MJ/m3. methodology consisted developing different experiments evaluate performance in each selected biomasses. percentage CH4 CO2 determined gas chromatography, from following results were obtained: rinds of, potato...

This study aimed to assess the benefits of solvent-free microwave extraction (SFME) on chamomile (Matricaria recutita L.) essential oil quality and yield compared by steam distillation (SD). The obtained SFME SD presented a blue color, solubility in 70% ethanol (v/v) four, relative density 0.929–0.925 g/mL, refractive index 1.5013–1.4790, an acidity value 6.23 3.43, respectively. yields were significantly different between methods, being highest (0.5 mL (0.083% v/w)) for 0.2 (0.03%) SD....

Mauritia flexuosa L.f. is a palm from the Amazon. Pulp and oil are extracted its fruits, which have high content of phenolic compounds unsaturated fatty acids, respectively. In this study, two extraction processes were compared at an volume 2000 L: (a) conventional solvent (CSE) with ethanol 80% for recovery phenolic-rich extracts, (b) supercritical fluid (SFE) followed by CSE to obtain extracts. According economic evaluation performed using SuperPro Designer 9.0, SFE+CSE was most...

In these times, consumers mistakenly believe that the terms “expiration date” and “best before” found on packages only convey information about food safety. Consequently, a misunderstanding of contributes to waste. this sense, understanding behavior con-sumer with respect two were evaluated; in addition, consumer's perception health risks consuming expired was analyzed. The research carried out population sector Lurigancho-Chosica, Lima – Peru; sample size 555 participants. An...

Verdolaga (Portulaca oleraceaL.) es una planta silvestre poco valorada en el Perú.
