ABSTRACT: This study evaluated physical characteristics, chemical composition, content of vitamin C, vitamin E, carotenoids, and minerals in biribiri fruits (Averrhoa bilimbi) from the Middle Doce River region (Minas Gerais, Brazil). Titratable acidity was determined by volumetric neutralization, pH by direct potentiometry, soluble solids by refractometry, humidity by gravimetry, ash by calcination in muffle, proteins by the micro-Kjeldahl method, dietary fiber by non-enzymatic gravimetric method and lipids using a Soxhlet extractor. Carotenoids and vitamin C were analyzed by high-performance liquid chromatography (HPLC) and vitamin E by HPLC with fluorescence detector. Fourteen minerals were analyzed by inductively coupled plasma atomic emission spectrometry. Biribiri showed high yield of edible portion (100%), low lipid, protein and carbohydrate content, and; consequently, low total energy value (25.36 kcal 100 g-1). The fruit also showed low dietary fiber content (0.62 g 100 g-1), total vitamin E (17.62 µg 100 g-1), total carotenoids (0.32 g 100 g-1), and high vitamin C, zinc, copper, iron content, manganese, molybdenum and chrome content. Regarding the heavy metals, the fruit showed no cadmium, and traces of aluminum and nickel. In conclusion, biribiri presented low energy value and expressive contents of dietary fibers, vitamin C, iron, manganese, molybdenum, chromium, zinc, and copper.

This study compares the content of basic nutrients (proteins, fats, digestible carbohydrates, dietary fiber and ash), steviol glycosides, selected antioxidants (vitamin C, total polyphenols) and antioxidant activity in dried leaves of Stevia rebaudiana Bertoni cultivated in Poland, Paraguay and Brazil and available in the direct sale. The basic chemical composition was determined by standard AOAC (Association of Official Analytical Chemists) methods. Content of steviol glycosides was determined by the UHPLC-UV chromatographic method. Total polyphenols content was expressed as gallic acid equivalent (GAE) and catechins equivalent (CE). Antioxidant activity was measured as ABTS●+ free radical scavenging activity. Dried leaves of S. rebaudiana grown in Poland had significantly higher contents of dietary fiber, and lower protein and ash content, compared to those derived from Paraguay and Brazil. The former had, however, considerably higher contents of total steviol glycosides, stevioside and rebaudioside D, compared to the remaining two plants. In the Paraguay-derived dried leaves, the content of rebaudioside A, C, E and rubusoside was found to be significantly lower. Dried leaves of S. rebaudiana Bertoni, cultivated in Poland, contained substantially more vitamin C and a similar content of total polyphenols, compared to those from Brazil and Paraguay. The examined material from Brazil and Paraguay plantations showed similar antioxidant activity, while that obtained from Polish cultivation was characterized by a significantly lower value of this parameter.

ABSTRACT Objective To determine the centesimal composition of minerals, fatty acids and vitamin C of leaves and tubers of crem, and to discuss the nutritional potential of the T. pentaphyllum species. Methods The centesimal composition of protein, lipid, fiber, ash and carbohydrate was determined by gravimetric analysis. Mineral composition was determined by optical emission spectrometry. Vitamin C was determined by dinitrophenylhydrazine method. Fatty acids were determined by gas chromatography. The percentage of recommended dietary intake of leaves and tubers of crem was calculated for each nutrient. Results A high content of fibrous fraction (63.07g/100g), potassium (4.55g/100g), magnesium (553.64mg/100g) and sulfur (480.79mg/100g) was observed in the chemical composition of leaves. In tubers, a high carbohydrate content was observed, with 62.60g/100g of starch and 3.43g/100g of fiber, as well as high potassium (0.58g/100g), sulfur (447.14g/100), calcium (205.54g/100g) and phosphorus (530.07g/100g) levels. The vitamin C content of tubers was 78.43mg/100g and the linoleic acid content was 0.455g/100g. The intake of 100g of crem leaves may contribute with 65% of the recommended dietary intake of sulfur. The intake of 100g of crem tuber may contribute with 106% of the recommended dietary intake of sulfur and 21% of the recommended dietary intake of Vitamin C. Conclusion The chemical composition of crem (Tropaeolum pentaphyllum Lam.) tubers and leaves demonstrated an important contribution of nutrients, mainly sulfur, vitamin C and linoleic acid in its tubers, indicating a high nutritional potential of this species.

Разработаны рецептуры и технологии конфет ручной работы пониженной калорийности, обогащенных биологически активными веществами без изменения оригинальных органолептических свойств. Обоснована возможность использования кэроба как заменителя какао. Исследована замена кэробом какао в различных концентрациях в рецептуре конфет. Описана технология конфет ручной работы функционального назначения с добавлением ягод черной смородины и порошка кэроба. Оценены показатели качества модельных композиций конфет с использованием порошка кэроба. Установлено, что совершенствование технологии производства шоколада позволило получить продукт с функциональным значением, сниженной энергетической ценностью, допустимыми органолептическими показателями и повышенным содержанием витамина С и пищевых волокон.Пищевая ценность одной порции (100 г) разработанной продукции – конфет с кэробом составила по сравнению с контролем соответственно, %: белки 5,9/8,1; жиры 56/60; пищевые волокна 64/36; витамин C 67/0; энергетическая ценность, ккал, 388/516. Снижение калорийности, повышение содержания витамина С и пищевых волокон в шоколадном батончике достигается за счет введения свежих ягод черной смородины. Применение измельчения без удаления семечек и кожицы ягод позволило повысить содержание пищевых волокон в готовом изделии. Recipes and technologies of handmade sweets of reduced caloric content, enriched with biologically active substances without changing the original organoleptic properties, have been developed. The possibility of using carob as a substitute for cocoa is justified. The substitution of carob for cocoa in various concentrations in the candy recipe was investigated. The technology of handmade functional sweets with the addition of black currant berries and carob powder is described. The quality indicators of model candy compositions using carob powder were evaluated. It was found that the improvement of the technology of chocolate production allowed us to obtain a product with a functional value, reduced energy value, acceptable organoleptic parameters and an increased content of vitamin C and dietary fiber. The nutritional value of one serving (100 g) of the developed products – sweets with carob – was in comparison with the control, respectively, %: protein 5,9/8,1; fat 56/60; dietary fiber 64/36; vitamin C 67/0; energy value, kcal, 388/516. Reducing the caloric content, increasing the content of vitamin C and dietary fiber in a chocolate bar is achieved by introducing fresh black currant berries. The use of grinding without removing the seeds and skins of berries allowed to increase the content of dietary fiber in the finished product.

Результаты исследования пищевой ценности ППЗ указывают на высокое содержание белка (12,4 %), пищевых волокон (11,7 %), жиров (2,9 %), витамина С (5,9 мг/100 г), энергетическая ценность составляет 321,1 ккал. Целью исследования является разработка рецептур и технологии пудинга с использованием полуфабриката из цельносмолотого пророщенного зерна вместо традиционных ванильных сухарей. Изучена возможность замены основного рецептурного компонента сухарей ванильных на ППЗ в рецептуре пудинга сухарного. Образец № 1 - пудинг с 25 %-ной заменой сухарей ванильных на ППЗ, образец № 2 - 50 %, образец № 3 - 75 %, образец № 4 - 100 %. В рецептуру пудинга из ППЗ был добавлен ванилин для формирования соответствующего вкуса. Установлено, что по органолептическим и физико-химическим показателям наиболее сбалансированным является образец с полной заменой ванильных сухарей на ППЗ. Кроме того, разработанный образец обладает меньшим содержанием жиров (на 16,7 %), по сравнению с контрольным образцом, уменьшилось содержание углеводов: моно- и дисахаридов (на 11,1 %), крахмала (на 9,3 %). Также увеличилось содержание пищевых волокон (на 457,1 %). Использование предложенного полуфабриката в технологии сладких блюд позволит не только расширить ассортимент, но и повысить пищевую и биологическую ценность изделия. The article presents the results of scientific research on the development of the formulation and technology of pudding using a semi-finished product from whole-ground sprouted grains (SPSG), which includes crushed sprouted grains (wheat - 14 %, rye - 44 %, barley - 14 %, oats - 28 %) with a particle size of 200-400 microns. The results of the study of the nutritional value of SPSG indicate a high content of protein (12.4 %), dietary fiber (11.7 %), fat (2.9 %), vitamin C (5.9 mg / 100 g), energy value is 321.1 kcal. The aim of the research is to develop recipes and technology for pudding using, instead of traditional vanilla rusks, a semi-finished product from whole-ground sprouted grains. The possibility of replacing the main recipe component of vanilla rusks with SPSG in the recipe for rusks pudding has been studied. Sample No. 1 - pudding with a 25 % replacement of vanilla rusks with SPSG; sample No. 2 - 50 %; sample No. 3 - 75 %; sample no. 4-100 %. Vanillin was added to the SPSG pudding formulation to create the appropriate flavor. It has been established that in terms of organoleptic and physicochemical indicators, the most balanced sample is with a complete replacement of vanilla rusks at the SPSG. In addition, the developed sample has a lower fat content (by 16.7 %) compared to the control sample, the content of carbohydrates decreased: mono- and disaccharides (by 11.1 %), starch (by 9.3 %). The content of dietary fiber also increased (by 457.1 %). The use of the proposed semi-finished product in the technology of sweet dishes will not only expand the range, but also increase the nutritional and biological value of the product.

The study investigated the Effect of ripening on the proximate, minerals, vitamins and photochemical composition of green locally cultivated banana cultivars peels. The matured unripe green banana fruits were collected from Ussa, Ussa LGA, Taraba State, Nigeria. The proximate, minerals, vitamins and photochemical composition of banana cultivars peels were determined using standard methods. The moisture, protein and carbohydrate content of the peel of unripe green banana decreased from 8.64 to 8.43, 5.47 to 5.23 and 73.04 to 72.42%, respectively, while the ash, fats and fibre content increased from 4.55 to 5.23, 5.35 to 5.57 and 2.96 to 3.13%, respectively, on ripening. The vitamin C, vitamin E, starch and lignin content of the peel of the green cultivar decreased from 0.08 to 0.11, 106.83 to 95.03, 1.07 to 0.97 and 5.84 to 5.55mg/100g, respectively, while the sugar increased from 0.95 to 1.09mg/100g on ripening. The green cultivar peel flour showed a significant decrease, p=0.05, in calcium(0.65 to 0.58mg/100g), potassium(4.63 to 4.36mg/100g), iron(0.28 to 0.23mg/100g) and zinc(0.4 to 0.3mg/100g), respectively, with relative increase in the phosphorous(0.35 to 0.37mg/100g) content on ripening. Ripening decreased the phenol (0.73 to 0.64mg/g), flavonoid (1.70 to 1.41mg/g), carotinod (5.05 to 3.35mg/g) and sterol (0.18 to 0.16mg/g) content of the green cultivar peel flour. The study has shown that ripening has generally improved the vitamins and the sugar content of the ripe banana peels.

Citrus fruit is preferred in the choice of consumers. Kumquat (F. margarita) is an unconventional citrus of increasing consumer interest because of its exotic flavor, and its functional potential that offers health benefits to consumers. It is a fruit traditionally consumed by whole fruit (peel and pulp), giving this fruit a distinctive flavor. For this reason, this study analyzed the physical, chemical, and nutritional characteristics of kumquat (peel and pulp). The physicochemical analysis was performed according to the Adolfo Lutz Institute. Analysis of moisture, ashes, macronutrients, and total dietary fiber was carried out according to AOAC. Minerals were analyzed by inductively coupled plasma optical emission spectrometry. Vitamins C and E, carotenoids and flavonoids were analyzed by HPLC. Phenolic compounds (Folin-Ciocalteu) and antioxidant capacity (DPPH) were determined by spectrophotometry. The kumquat had low pH, soluble solids content and low caloric value. It was a source of dietary fiber, minerals (K, Ca, P, Mg) and carotenoids; the most expressive was α-carotene (661.81 μg 100 g−1). The ascorbic acid concentration was 2326.24 μg 100 g−1. α-tocopherol (569.00 μg 100 g−1) was the most expressive component of vitamin E. There was a presence of apigenin and eriodictyol. The fruit (peel and pulp) has a high concentration of total phenolic compounds (98.55 ± 1.93 mg GAE 100 g−1) and good antioxidant capacity (62%) was found. Kumquat is a good source of fiber and vitamin A, and due to its antioxidant capacity and the presence of other essential and beneficial nutrients for a diet, consumption of kumquat can be suggested to complement the diet. This fruit is a viable food alternative, and its consumption should be encouraged, contributing a source of income, sovereignty, and food security.

AbstractObjectiveThe present review aimed to quantify the association of dietary intake and circulating concentration of major dietary antioxidants with risk of total CVD mortality.DesignSystematic review and meta-analysis.SettingSystematic search in PubMed and Scopus, up to October 2017.ParticipantsProspective observational studies reporting risk estimates of CVD mortality across three or more categories of dietary intakes and/or circulating concentrations of vitamin C, vitamin E and β-carotene were included. A random-effects meta-analysis was conducted.ResultsA total of fifteen prospective cohort studies and three prospective evaluations within interventional studies (320 548 participants and 16 974 cases) were analysed. The relative risks of CVD mortality for the highest v. the lowest category of antioxidant intakes were as follows: vitamin C, 0·79 (95 % CI 0·68, 0·89; I2=46 %, n 10); vitamin E, 0·91 (95 % CI 0·79, 1·03; I2=51 %, n 8); β-carotene, 0·89 (95 % CI 0·73, 1·05; I2=34 %, n 4). The relative risks for circulating concentrations were: vitamin C, 0·60 (95 % CI 0·42, 0·78; I2=65 %, n 6); α-tocopherol, 0·82 (95 % CI 0·76, 0·88; I2=0 %, n 5); β-carotene, 0·68 (95 % CI 0·52, 0·83; I2=50 %, n 6). Dose–response meta-analyses demonstrated that the circulating biomarkers of antioxidants were more strongly associated with risk of CVD mortality than dietary intakes.ConclusionsThe present meta-analysis demonstrates that higher vitamin C intake and higher circulating concentrations of vitamin C, vitamin E and β-carotene are associated with a lower risk of CVD mortality.
