Brazil stands out for its diversity of native palm trees, with about 37 genres and 387 species described. Oenocarpus bacaba Mart.  Commonly known as bacabeira, it is an oleaginous fruit, usually eaten by the riverside and indigenous population in the Amazon region. This study aimed to analyze the physical and chemical characteristics and the lipid profile of the eatable part of bacaba, from Pimenta Bueno - RO. It was conducted physical assessments of the length, diameter, and weight. For the physical and chemical analyze it was characterized according to the Total titratable acidity, pH, reducing sugar, non-reducing and total sugar, moisture, total soluble solids, ashes, protein, lipids and fatty acids. The results for titratable acidity was 0,22g/100g of citric acid, pH 5,83, reducing sugar 4,64g /100g of glucose, total sugar 4,75g /100g of glucose, moisture 30,36%, total soluble solids 69,63g/100g, ashes 1,53g/100g, protein 4,61g/100g, lipids 21,02g/100g. The results demonstrated that the main components of the eatable parts from bacaba are lipids with lower levels of sugar and proteins, making it possible to classify bacaba as a fruit with high oleaginous content slightly acid and low moisture. Bacaba oil showed greater abundance of fatty acid oleic, the main constituent of olive oil. Therefore, considering the obtained data from this study with the nutritional and sensory characteristics described in the literature related to the similarities to the olive oil, the bacaba oil inserted into the feeding to replace the olive oil and other vegetable oils as a source of omega 9.

The tropical vegetable, brinjal is cultivated throughout the year in Bangladesh but the crop is infested by a number of insects including jassid. This study investigated the effects of different biophysical and biochemical characteristics of twelve brinjal germplasms on the abundance and infestation of jassid. The experiment was conducted during September 2018 to March 2019 in Gazipur, Bangladesh with twelve brinjal germplasms namely BD-7320, BD-7328, BD-9952, BD-10154, BD-10158, BARI Begun-1, BARI Begun-4, BARI Begun-5, BARI Begun- 6, BARI Begun-7, BARI Begun-8 and BARI Begun-9. The incidence of jassid was recorded from 3rd December to 26th March, and the lowest population was found on BARI Begun- 6. Among the biophysical traits, plant height, number of branch and leaf per plant, and leaf area exerted significant positive correlation; whereas trichome on lower and upper surfaces of leaf, spine per stem and leaf showed significant negative correlation with the abundance of jassid. On the other hand, moisture, reducing sugar, total sugar and protein content of the leaves and fruits, chlorophyll content of the leaves exerts significant positive correlation but ash and pH contents of the leaves and fruits were negatively correlated with the abundance of jassid. Jassids showed the lowest level of leaf infestation on BARI Begun-6, which could be for further analysis to develop jassid resistant brinjal. SAARC J. Agric., 19(1): 81-91 (2021)

A modification on nixtamalization process of dent corn (Zea mays identata) was conducted in order to recover natural folic acid-rich corn. Nixtamalization process on varieties of white dent corn and yellow dent corn subsequently were performed by steeping solution of Ca(OH)2 at concentrations of 0, 10, 20 and 30 % (w/w corn dissolved protein) for 18 hours, and boiling at 90 °C for 15, 30, 45 and 60 minutes. Result of research showed that concentration of Ca(OH)2 solution becoming more and more high and long boiling time increased both folic acid and reducing sugar, dropped total solids and total sugar, and fluctuated dissolved protein for both types of corn. Nixtamalization optimalization of white dent corn and yellow dent corn were achieved at combination of Ca(OH)2 20 % (w/w corn dissolved protein) for 60 minutes of boiling and Ca(OH)2 30 % for 30 minutes of boiling and gave folic acid of 466.81 and 506.74 μg/mL, respectively. In this condition, it is occurred an increase of folic acid 192.3 % (1.9 folds) and 139.89 % (1.4 folds) when compared to initial material of corn. Identification on folic acid monomer and glutamic acid monomer of both nixtamalized dent corn and yellow dent corn at optimum operation condition displayed domination of folic acid monomer with molecular weight (MW) 442.56 Dalton (Da.) with relative intensity 25.51 %, and 441.73 Da. with relative intensity 100 %, while glutamic acid monomer of nixtamalized yellow dent corn and nixtamalized white dent corn were dominated by monomer with MWs of 148.27 Da. and 148.32 Da., and relative intensity 3.73 and 1.8 %.

Imitation cherry of Karonda was prepared from three cultivars viz., Pant Manohar, Pant Sudarshan and Pant Suvarna picked at 40, 60 and 80 days after fruit set. The storability of imitation cherry was evaluated at ambient room temperature for a period of nine months. The imitation cherry prepared at 80 days after fruit set showed maximum TSS (77.83 %), reducing sugar (42.21 %), non-reducing sugar (28.21 %), total sugar, ascorbic acid (6.69 mg/100g), phosphorus (3.55 mg/100g), calcium (1.23 mg/100g), iron (3.72 mg/100g), non-enzymatic browning, colour, appearance, aroma, taste and overall acceptability. Gradual reduction in TSS, reducing sugar, total sugar, titratable acidity, colour, appearance, aroma, taste, texture and overall acceptability were observed during the nine months storage period. However, non-reducing sugar, ascorbic acid and non-enzymatic browning were increased with the increase in storage period. Overall acceptability of the product ranged from 8.15 to 8.43 on 9 point hedonic scale at various intervals up to 9 months of storage. There was no yeast and mould growth being observed during the entire storage period. Imitation cherry prepared from Pant Suvarna at 80 days interval after fruit set proved significantly best in quality because of its higher nutritional and sensory characters.
