Sweet potato is one of the seven major staple crops in the world. Although most cream-fleshed sweet potatoes are produced locally, orange-fleshed sweet potato (OFSP) is an excellent source of beta-carotene and can be promoted to alleviate vitamin A deficiency. The aim of this study was to evaluate the retention of total carotenoids (TC) and all-trans-beta-carotene (ATBC) after processing and storage of cookies with different proportions of OFSP and margarine. Cookies formulated with 18 to 22.23 g/100 g of OFSP and 28.57 to 34.6 g/100 g of margarine were analyzed by spectrophotometry and high-performance liquid chromatography. The formulation containing the highest content of OFSP (22.23 g/100 g) and 32.84 g/100 g of margarine showed greater retention of TC and ATBC after processing. Among the other samples with the same proportion of OFSP, the one containing the highest margarine concentration (34.6 g/100 g) has shown a greater capacity to maintain TC and ATBC during storage (up to 56 days), demonstrating lipids important role in the preservation of these components.

Β Carotene

Carotenoids and folate are two mandatory supplying micronutrients for children or pregnant women. Inadequate intake of these two nutrients was relevant to a higher mortality of both children and pregnancies. This study is intended to investigate the thermal impact on the changes of carotenoids and folate in sweet potato roots (SPRs). Carotenoids were identified by high performance liquid chromatography (HPLC) while the folate was estimated using a microbial assay. An obvious decline was observed in total carotenoids after heating. Nevertheless, the content of provitamin compound β-carotene exhibited incredible stability during steaming and α-carotene multiplied in certain varieties, evidencing that SPRs could be an efficient way for addressing Vitamin A deficiency (VAD). As for the total folate contents, two varieties were found no significant loss after thermal process while the others showed a significant decrease. The results indicated that steaming process led to generally loss of both carotenoids and folate while the α-carotene and β-carotene were well preserved. The information provided by this study might help with enhancing the food quality in processing industry and the understanding in the nutrition changes during steaming.

Marshmallow belongs to a high-calorie food that requires a low-calorie substitute for sucrose, one of which is sorbitol. Marshmallow has the potential to become a functional food with the addition of inulin contained within white sweet potatoes. Inulin refers to a type of fructan carbohydrate which contains fiber and has the potential as a prebiotic that is beneficial for the human’s body. This study aims to determine the effect of the addition of white sweet potato (Ipomea batatas L.) inulin extract and sorbitol on the physical, chemical and organoleptic characteristic of marshmallows and to obtain the best marshmallow’s formula through white sweet potato (Ipomea batatas L.) inulin extract and sorbitol addition. The completely randomized design method (CRD) applied in this study consisted of one factor, namely the difference in formulation between the concentration of white sweet potato inulin extract (2% and 3%) and the concentration of sorbitol (25%, 50%, and 75%). The statistical analysis utilized the One Way Analysis of Variance (ANOVA) method using SPSS. The results of this study indicated that the addition of white sweet potato inulin extract and sorbitol had a significant effect on tensile strength, density, moisture content, ash content, total calories, dietary fiber, and organoleptic characteristics of marshmallows. The best formula for marshmallows was formula 4 with the addition of 2% white sweet potato inulin extract and 50% sorbitol.

Vinegar is a natural product rich in bioactive compounds such as phenols, flavonoids, and organic acids. Several factors affect the quality of vinegars such as apple origin, environmental conditions, production methods, processing, and storage conditions. We investigated the quality of apple vinegars as well as their physicochemical properties and the antioxidant and antibacterial activities of vinegars collected from different areas in Morocco. For physicochemical properties, the outcomes showed the following values: pH (3.18–3.83), electrical conductivity (2.11–2.90), acidity (0.24–5.6), Brix (3.25–6), and density (1.0123–1.0233). The polyphenols content of samples was 68.91 mg AG/100 mL in sample S6 as the minimum value and 147.54 mg AG/100 mL in sample S2 as the maximum value. The best ability to scavenge the DPPH radical was observed in sample S3 (IC50 = 0.45 ± 0.013 µL/mL). Sample S2 showed moderate antibacterial effect against microorganisms tested with MICs ranging from 0.78 µL/mL to 1.125 µL/mL and with a diameter of inhibition ranging from 15.65 mm to 27.65 mm. In addition, a strong correlation was observed between the antibacterial activity of vinegars and physicochemical parameters (pH and total acidity). These outcomes have shown that our vinegar samples are an excellent source of bioactive compounds with potent antioxidant and antibacterial potentials.

Pumpkin is rich in beta-carotene which is used for preventing vitamin A deficiency. About 50 of carotenoids are the "Provitamin A compounds" which are precursors of retinol. Retinol is the active form of vitamin A. It plays an important role in vision. Beta carotene is an important anti-oxidant which protects the damaging of body cells by high free radical content because of its radical scavenging activity. The purpose of this study was to quantify the beta carotene and vitamin A present in yellow and green pumpkins. High performance liquid chromatography (HPLC) was used to analyze beta carotene and vitamin Yellow pumpkin contained the highest values of both the �-carotene and vitamin A than green pumpkin. The results illustrated that green pumpkin (Curcurbita pepo) possess 20.3µg/g beta carotene; 52.6µg/g vitamin A and yellow pumpkin (Curcurbita maxima) contains 35.7µg/g beta carotene and 60.2 µg/g vitamin A in their pulp. It was concluded that there is a need to promote the use of locally available sources of carotene and retinol to overcome nutrition deficiency in the people.

Roots of orange-fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and crucially important remedy for vitamin A deficiency. The cream or white-fleshed varieties, on the other hand, have a sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. Development of sweet potato genotypes that can combine these two important quality traits is the objective of this breeding work. A diallel experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out and thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for the traits. The average β-carotene content among the progenies was 2.86 (mg/100g.f.w) while the dry matter cttgontent had a mean value of 31.89%. The cross progenies 199024.2 x Excel had the highest beta carotene (14.37mg/100g.f.w) content with the highest dry matter content (40.10%) and are therefore recommended for further evaluation.

Abstract Botanical extracts are standardized to 1 marker compounds (MCs). This standardization provides a certain level of quality control, but not complete quality assurance. Thus, industries are looking for other satisfactory systems to improve standardization. This study focuses on the standardization of herbal medicines by combining 2 parameters: the concentration of the MC and antioxidant capacity. Antioxidant capacity was determined with the oxygen radical absorbance capacity (ORAC) method and the concentrations of the MCs, by high-performance liquid chromatography. Total phenols were also determined by the Folin-Ciocolteau method. The ORAC values, expressed as mol Trolox equivalents/100 g (ORAC ), of 12 commercial herbal extracts were related to the ORAC values of the respective pure MCs at the concentrations at which the MCs occur in products (ORAC-MC ). The ORAC values of 11 extracts were higher than those of the respective MCs and the ratios ORAC-MC /ORAC ranged from 0.007 to 0.7, whereas in the case of Olea europaea leaves, the same ratio was 1.36. The ORAC parameters and their ratios, as well as the linear relationship between ORAC-MC and ORAC , are described and discussed as tools for improving the standardization of herbal products and detecting modifications due to herb processing and storage.

 RESUMO - O presente estudo teve por objetivo determinar a retenção de carotenoides em milho biofortificado com carotenoides precursores de vitamina A (ProVA) processado através da moagem a seco e nos derivados canjica, fubá e creme de milho, durante o armazenamento pós-processamento por 24 dias. O perfil de carotenoides foi determinado por cromatografia líquida de alta eficiência (CLAE) e o total de carotenoides precursores de vitamina A foi quantificado a partir das concentrações de α-caroteno, β-caroteno e β-criptoxantina. Os produtos da moagem via seca dos grãos de milho biofortificado (BRS 4104) apresentaram médias percentuais de retenção real de carotenoides totais (CT) de 75,37% (canjica), 73,51% (fubá) e 59,47% (creme) em relação aos grãos, enquanto para carotenoides ProVA os percentuais foram de 74,20% (canjica), 75,21% (fubá) e 60,55% (creme), evidenciando, em média, 30% de perdas como efeito da moagem a seco na retenção de carotenoides presentes nos grãos de milho. Durante o armazenamento ao longo do período de 24 dias ocorreu diminuição linear da retenção de CT e de ProVA nos três derivados estudados. Menores concentrações de carotenoides totais e ProVA nos produtos da moagem via seca de milho (canjica, fubá e creme de milho) e a redução na retenção dessas substâncias observadas durante armazenamento devem ser consideradas, quando da utilização de produtos do milho biofortificado como estratégia complementar em programas nutricionais para redução da deficiência de vitamina A em humanos.Palavras-chave: Zea mays, processamento, degradação, pró-vitamina A, compostos bioativos.CAROTENOIDS RETENTION IN BIOFORTIFIED MAIZE PROCESSED THROUGH DRY MILLING AND DURING STORAGE OF THE RESULTING PRODUCTS  ABSTRACT - The objetive of the present study was to determine the retention of carotenoids in maize biofortified with vitamin A precursors (ProVA) processed through dry milling and during storage of the products flaking grits, corn meal and fine meal. Carotenoid profile was determined by high performance liquid chromatography (HPLC) and the total vitamin A precursor carotenoids quantified considering the concentration of α-carotene, β-carotene and β-cryptoxanthin. Dry-milling products of ProVA maize BRS 4104 showed mean true retention for total carotenoids of 75.37% (flaking grits), 73.51% (corn meal) and 59.47% (fine meal), whereas retention for ProVA carotenoids were 74.20% (flaking grits), 75.21% (corn meal) and 60.55% (fine meal) revealing 30% of losses on average due to dry milling effect on the retention of carotenoids present in the maize grains. During the 24-day storage period there was a linear decrease in the retention of total carotenoids and ProVA in the three maize biofortified products. Reduced total carotenoids and ProVA contents in the maize dry milling products (flaking grits, corn meal and fine meal) compared to the whole kernels as well as the important losses of these substances during storage is recommended to be taking into account when using biofortified maize as a complementary strategy in nutrition programs focused on improvement of vitamin A deficiency in humans.Keywords: Zea mays, processing, degradation, pro-vitamin A, bioactive compounds.
