Wild edible fruits have been used centuries by local people mainly for nutrition purposes and they have attracted the attention of researchers in the last decade throughout the world. Among wild edible fruits, the strawberry tree (Arbutus unedo) is widely distributed mainly in Mediterranean countries. However, the lack of information about strawberry tree genetic resources in Mediterranean countries is a major cause of its low exploitation by breeders. For a practical use and exploitation of the strawberry tree native germplasm, phenological, morphological, and biochemical characterization of the plant is essential. In this study, some important phenological, morphological, and biochemical characteristics of sixteen local strawberry tree genotypes were determined. Significant variations (p < 0.05) were observed in most of the investigated phenological, morphological, and biochemical traits of the genotypes. The genotypes were harvested between 2–21 November. The fruit weight and the number of fruits per cluster of the genotypes varied from 3.89 to 6.86 g and 3.61 to 7.94, respectively. Vitamin C and total dietary fiber contents of genotypes were found quite variable, ranging from 58 to 93 mg/100 g and 7.04 to 12.36 g/100 g, respectively. The fruits of the strawberry tree include mainly fructose and glucose rather than sucrose. Local strawberry tree genotypes are found to be promising for further valorization through horticultural characteristics for breeding. Some genotypes had significantly higher fruit weight, vitamin C concentrations, total dietary fiber, and total phenolic concentration and may be good selections for producing health products.

Arbutus unedo spirit is a valuable product in Mediterranean countries. This spirit is usually marketed in Portugal without wood ageing. This work aims to characterize the ageing effect on the Arbutus unedo spirit, for three and six months with oak wood (Quercus robur L.) submitted to different toasting levels, based on its chemical composition and its sensory properties. For this purpose, several parameters were analysed: acidity, pH, dry extract, and volatile compounds (methanol, acetaldehyde, ethyl acetate and fusel alcohols). The volatile compounds were identified by GC-MS and quantified by GC-FID. Sensory analysis was performed by a trained panel, who have profiled this beverage, as well as the changes acquired during ageing. Spectroscopic techniques, namely FTIR–ATR, were applied to discriminate the different beverages produced. The results highlighted an increase in Arbutus unedo spirit’s quality with the wood contact, mainly based on the sensory attributes. Additionally, they showed that the best beverages were produced using oak wood with medium toasting levels during three months of ageing.

In Colombia, a high amount of fruit waste is currently generated. These causes a negative environmental impact due to its high organic load. However, this type of waste has compounds in its structure that can be used in order to reduce the environmental impact and to obtain added value. The main of this study was to characterize bromatologically sixteen residues of fruit processing in Colombia, in order to propose a possible use in the food industry. The bromatological characterization of the waste was carried out by means of the quantification of dry matter (ASTM E1756-08), ash (ASTM E1755-01), proteins (Kjeldahl method), crude fats (AOAC Official Method), total dietary fiber (AOAC 993.21) and carbohydrates. It was found that grape and soursop seeds, lulo peel and tree tomato stem presents the highest total dietary fiber with content percentages above 50 %. Also, tree tomato, soursop, tangerine and orange seeds are an important source of protein and crude fats, with values highest than 12 and 27 %, respectively. It was also found that pineapple, mango, soursop and grape peel have a carbohydrate content greater than 50%. As a conclusion, the results of this study demonstrate that fruit waste have a potential use in the food industry, due to their protein, crude fat, total dietary fiber and carbohydrates content.

AbstractStrawberry trees (Arbutus unedoL.) are naturally grown in particular Black Sea and Mediterranean regions of Turkey with great diversity due to continuous seed propagation for centuries. The trees differ in terms of most of the horticultural characteristics. We investigated the phenolic compounds and the biochemical and pomological characteristics of the fruits of eight strawberry tree selections naturally grown in the western part of Turkey. Significant differences were found among the genotypes in terms of their phenolic compounds and their biochemical and pomological characteristics. Among soluble sugars, fructose (11.63 g 100 g−1) was the dominant sugar, followed by glucose (6.10 g 100 g−1) and sucrose (1.44 g 100 g−1) for all the genotypes. Positive correlation was found between fruit weight and soluble sugar content. Malic acid was the major organic acid (0.67-2.33 g 100 g−1), and the second major organic acid in strawberry tree fruits was citric acid (0.25-0.87 g 100 g−1). Vitamin C content was an average of 56.22 g 100 g−1for the eight genotypes. Among phenolic compounds, gallic acid was dominant (1.62-7.29 mg 100 g−1), followed by chlorogenic acid (1.23-3.14 mg 100 g−1), on an average basis.

Purple eggplant is a vegetable that is commonly cultivated in Indonesia. Product innovation is needed to increase people's consumption of eggplants, such as being made into Velva. Purple eggplant has the potential to be used as a raw material for making Velva because it has a thick pulp. The processing of Velva can reduce the nutritional content of purple eggplant. The fortification of passion fruit juice in this study is expected to increase the nutritional value of purple eggplant Velva. The research method used a completely randomized design with two repetitions and three levels of concentration of passion fruit juice fortification, namely 10 percent, 20 percent, 30 percent. Observation parameters included vitamin C content, dietary fiber, and antioxidant capacity. The data from the analysis were statistically tested using ANOVA. If a difference is found, then proceed with Duncan's Multiple Range Test (DMRT). Based on the results of the study, the concentration of 30 percent passion fruit juice fortification showed the highest results for the content of vitamin C and total dietary fiber, namely vitamin C 17.144 mg / 100gr and total food fiber of 42.481 percent. The highest IC50 content was obtained from the fortification concentration of 10% passion fruit juice with a value of 92.338 ppm.

Abstract The Uppsala methodology for rapid analysis and characterization of total dietary fiber, defined as the sum of dietary fiber polysaccharides (DFP) and Klason lignin, was studied. A sugar- and starch-free residue was prepared by treatment with a thermo-stable amylase and amyloglucosidase. Neutral DFP residues were quantified by gas chromatography as alditol acetates after acid hydrolysis of this residue, and the acidinsoluble fraction, Klason lignin, was determined gravimetricaliy. Uronic acid residues were quantified by decarboxylation of the original sample. The efficacy of the Uppsala methodology was tested with foods varying in fiber content and composition, including heat-treated samples. The present method allowed the analysis of up to 40 samples per week. It had good repeatability and coefficients of variation of 3-5% for the main fiber components. Fiber contents determined with the method were higher than those determined with a similar method that excludes Klason lignin and starch resistant to amylases but soluble in dimethyl sulfoxide and lower than those determined with an enzymatic/gravimetric method. Important aspects of fiber analysis, like enzyme purity and the recovery of soluble fiber on ethanol precipitation, also were investigated.

The flour from the pulp of marolo (Annona crassiflora Mart.) is an important source of fiber, however, its use as a food ingredient requires investigation as to its functionality. Thus, this work aimed to evaluate the physical, chemical, nutritional and technological functional properties of the flour obtained from the pulp of marolo, thus verifying its potential application in food products. The analyzes performed on the flour were proximal composition, mineral composition, vitamin C content, total carotenoids, beta-carotene, antioxidant activity and technological functional properties. The flour presented considerable amounts of fibers, especially the insoluble fraction, being 25.47 g.100g-1, 8.57 g.100g-1 for soluble dietary fiber and 34.04 g.100g-1 for total dietary fiber. . The levels of vitamin C and total carotenoids, observed in the flour of the pulp of marolo, were 173.77 mg.100g-1, 0.56 mg.100g-1 and 0.08 mg.100g-1, respectively. The minerals that showed the highest concentration in the pulp flour were phosphorus (1768.53 mg.kg-1) and calcium (1512.73 mg.kg-1). The antioxidant activity was more effective when performed in aqueous extraction. The flour has shown to have important technological functional properties, such as solubility in water and the ability to form emulsion. Therefore, marolo pulp flour has the potential to be commercialized and used in food products in order to improve and enrich its nutritional and technological qualities.
