Fruit waste extract was selected as the sole substrate for carotenoid production and the effect of parameters like pH, temperature and agitation have been studied. A two-step simple sequential strategy was employed for the optimization of carotenoid production by Rhodotorula rubra. In the first step, one factor at a time was employed to evaluate the impact of pH on carotenoid production. Th...

The Brazilian guava processing industry generates 5.5 M Mg guava waste year(-1) that could be recycled sustainably in guava agro-ecosystems as slow-release fertilizer. Our objectives were to elaborate nutrient budgets and to diagnose soil, foliar, and fruit nutrient balances in guava orchards fertilized with guava waste. We hypothesized that (1) guava waste are balanced fertilizer sources that ...

pomegranate (punica granatum l.), lythraceae, is mainly grown in mediterranean region. it is one of the major cultivated productions of iran, which have been used in folk medicine for many centuries. it has been proved that pomegranate has a high antioxidant activity and is effective in the prevention of atherosclerosis. this study compares the antioxidant activity, total phenolic and flavonoid...

BACKGROUND The 2010 Healthy, Hunger-Free Kids Act required the USDA to update the nutrition standards of the National School Lunch Program. New policies were implemented in the 2012-2013 school year. These changes were followed by anecdotal reports of increased food waste. Empirical research is needed to reliably measure student intake and plate waste before and after this policy change. METH...

BACKGROUND As a by-product of tropical fruit juice industry, passion fruit peel is a valuable functional food. It is rich in antioxidants. To determine its potential antioxidant properties of passion fruit peel, this study aimed to evaluate the effect of extraction conditions on total phenolic content and antioxidant activity. METHODS The extraction conditions were selected from different per...

OBJECTIVE To (i) evaluate food choices and consumption patterns of elementary- and middle-school students who participate in the National School Lunch Program (NSLP) and (ii) compare students' average nutrient intake from lunch with NSLP standards. DESIGN Plate waste from elementary- and middle-school students' lunch trays was measured in autumn 2010 using a previously validated digital photo...

This concept paper summarizes key “hotspots” for waste generation along the food supply chain and identifies a range of existing solutions/measures that can help producers, retailers and consumers reduce the amount of food that is wasted. The majority of food waste of 71–92 kg/head/year in Western Europe was found to originate from private households (61%), followed by restaurants and canteens ...

The fruit of Basella alba is often considered as waste so the study was aimed at exploring the feasibility of using the fruit as natural colorant using acidified methanol extraction. The extracted betacyanin pigments then were exposed to number of environmental conditions, which could destabilize the betacyanin molecules. These environmental conditions were included fourteen different pHs, vari...

PURPOSE To evaluate the antitumor and antimicrobial activity of ethanolic extract of Morinda citrifolia L. fruit cultivated in southeastern Brazil. METHODS Preparation ethanolic extract of the fruit of Morinda citrifolia L. Culture of melanoma cells B16-F10 for treatment with ethanolic extract of Morinda citrifolia L. fruit to determine cell viability by MTT and determination temporal effect ...

Food waste from fish and fruit shops was used as an alternative to the grain in grower-finisher pig diets. Two diets were formulated on an iso-nutrient basis (14 MJ digestible energy per kg, 160 g crude protein per kg on a dry-matter basis) to contain 0 g of food waste per kg in the control diet and 50 g of fish-shop waste per kg and 120 g of fruit-shop waste per kg in the experimental diet. In...
