“…However, in the case of the analyzed pseudofruits, as acidity increased during maturation, this may suggest that some other compounds may be involved, such as phenolic compounds (Fennema 1996). In H. dulcis pseudofruits, changes in the profile of organic acids through maturation have been reported in Maieves et al (2015a). In this study, tartaric acid was found as predominant in immature pseudofruits, being probably responsible of astringency, with a decrease through maturation, while citric acid was the major one at maure stages, Hd03 to Hd05.…”

The study of physical properties of the pulp of exotic fruit products and its rheological behavior can contribute to improve their quality for food uses. The aim of this study was to evaluate color, thickness, acidity, texture, rheological behavior in pseudofruits (peduncles) of Hovenia dulcis in different stages of maturation. The experimental rheological data were adjusted for models of Ostwald‐de Waele and Herschel‐Bulkley. Through maturation process of H. dulcis pseudofruits, parallel to the increase in size, a decrease in texture occurs. The softening is closely associated with ripening, reaching its apex in the stadium Hd04, when the peduncle is fully mature and already in full senescence period in Hd05 stage. The appearance of flow curves indicates a non‐Newtonian behavior pseudo‐plastic, which is proven when adjusted to the models. From their physicochemical characteristics (color, thickness, pH and acidity and texture) Hd04 and Hd05 are the most suitable stages for human consumption of H. dulcis pseudofruits, for either fresh consumption or the elaboration of manufactured products. All these results are important to define processing conditions, and thus facilitate and increase the use of H. dulcis pulp in the food industry. Practical Statement In this work, we studied Hovenia dulcis Thunb. peduncles (pseudofruits), a crop is gaining interest in Brazil, and presents great potencial for food uses, as well as like an ingredient in dietary supplemets or nutraceuticals. To our knowledge, this product had been scarcely studied. This work present a study on the evolution of the product through maturation regarding its physicochemical parameters. Data about color, thickness, acidity, texture and rheology behavior are presented. Flow curves reflect non‐Newtonian pseudoplastic behavior (Ostwald‐de Waelle model) and principal components analysis well describes physicochemical properties through maturation of pseudofruits. These results would permit a better handling and selection of the optimal prime matter for industrial purposes.

“…15,16 According to Bampi et al 13 the peduncles are rich in sugars and have a high content of dietary fiber. In addition, the peduncles are known to be a rich source of antioxidant compounds [17][18][19][20] as well as exhibit pharmacological activities, e.g. improve the alcoholic hepatic steatosis and inflammation via regulation of lipid and inflammation metabolism 21 and have preventive effects…”

In this study, the fatty acid (FA) composition of the Japanese grape (Hovenia dulcis) seed oil (JGSO) was firstly evaluated. It was found that the seed oil is rich in alpha-linolenic acid (LNA), containing approximately 425 mg LNA g -1 of total lipids. A fish diet supplemented with JGSO was prepared and supplied to Nile tilapia to investigate the FA composition of the fillets. For this, Nile tilapia were submitted to two feeding treatments: a control diet with 4.2% of soybean oil, and a diet supplemented with 4.2% of JGSO. The LNA, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) values increased significantly (406, 153 and 126%, respectively) with JGSO in the diet and with an increase in feeding time, while the nutritional quality indexes, n-6/n-3 ratio and index of thrombogenicity, decreased 2.8 and 1.4 times, respectively. Thus, the replacement JGSO in the diet raised the nutritional lipid quality in Nile tilapia.Keywords: fatty acids, omega-3, Oreochromis niloticus, supplementation, LNA IntroductionOmega-3 polyunsaturated fatty acids (n-3 PUFA), especially alpha-linolenic acid (LNA, 18:3n-3), eicosapentaenoic acid (EPA,, and docosahexaenoic acid (DHA,, have been extensively studied and said to be beneficial to human health. [1][2][3] A high ratio of dietary n-6/n-3 (omega-6/omega-3) has been reported around the world, reaching ratios between 15:1 and 20:1, while the recommended value is between 2:1 and 1:1. 4 This imbalance in the n-6/n-3 ratios is the result of an excess intake of omega-6 polyunsaturated fatty acids (n-6 PUFAs) from corn, soybean, and sunflower oils. Furthermore, a high intake of saturated fatty acids (SFA) such as myristic acid (14:0), palmitic acid (16:0), and stearic acid (18:0), may contribute to an increase in the indexes of atherogenicity (IA) and thrombogenicity (IT) 6 and to a reduction in the hypocholesterolemic/hypercholesterolemic fatty acid ratio (HH). 7Around the world, flaxseed, perilla, and chia are known sources of LNA, [8][9][10] while fish and microalgae oils rank among the most important sources of EPA and DHA. 11,12 The Japanese grape is originally from Japan, but has quickly expanded to other countries, such as India, Paraguay, Argentina, and Brazil, due to its easy adaptation to the soil and resistance to cold. 13 The Japanese grape are deciduous trees, growing to 10 to 15 m and reaching 20 to 40 cm in diameter of the trunk, commonly used for ornamental and reforestation purposes, and the wood for production of energy, paper and cellulose. The fruit is a small dry capsule from 6 to 7 mm in diameter containing 2 to 4 seeds, attached to a peduncle, which becomes thickened and fleshy when mature, which is also sweet and pleasant-tasting. The seeds are brown with a circular shape from 4 to 8 mm in diameter.14 The peduncles (pseudofruits) can be consumed in natura or in dehydrated form and are also used for alcoholic fermentation, to produce wine or vinegar. 15,16 According to Bampi et al. 13 the peduncles are rich in sugars and have a high content of dietary fi...

Styphnolobium japonicum (L.) Schott is widely cultivated in China, and its flowers and flower buds (FFB‐SJ) are commonly used as traditional Chinese medicine. This work aimed to assess variations in the chemical components and antioxidant and tyrosinase inhibitory activities of S. japonicum extract during five flower maturity stages (ES1–ES5). The results showed that the contents of total flavonoids, rutin, and narcissin were highest at ES1, whereas the contents of quercetin and isorhamnetin were highest at ES3. ES1 presented considerable antioxidant activities in terms of reducing power (RP) and 1,1‐diphenyl‐2‐picrylhydrazyl radical (DPPH.) and hydroxyl radical (.OH) scavenging capacity, whereas ES3 showed excellent tyrosinase inhibitory activity and 2,2′‐azinobis(3‐ethylbenzothiazoline‐6‐sulfonic acid) radical (ABTS.+)‐ and O2.−‐scavenging capacity. Rutin and quercetin are the main bioactive components of FFB‐SJ with antioxidant and tyrosinase inhibition, and the immature flower buds of S. japonicum (S2 and S3) with excellent biological activities and relatively high extract yields were the best for product development.
