<p align="”justify”">Aren is a plant source of raw material for sugar that has been carried out from generation to generation. All parts can be used, both as a source of food and non-food. However, the main product that has been concerned is still focused on sap, as a raw material for sugar. To increase the variety of products from sap, it can be processed into syrup so that its use is more varied. Therefore, in 2018 the sap of palm sugar for palm juice processing has been carried out into syrup. The tapping of palm sap is carried out in farmer’s gardens in Tinoor village, Tomohon Municipality, North Sulawesi Province. Syrup processing is carried out at the Indonesian Palm Crops Research Institute Laboratory, and part of the analysis is carried out at the Engineering, Chemical and Biochemical Laboratory of the Agricultural Product Technology Department, UGM-Yogyakarta. The results showed that palm sugar syrup that has been carried out in the level of total soluble solids, namely 65. Brix, has the following characteristics, water content ranges from 24.16% - 31.73%, viscosity 140cP-2,336cP, total content 62.77%-68.14%, saccharose  57.55%-62.22%, reducing sugar 1.29% -4.11%, phenolic content (antioxidants) 0.13% - 0.29%. Processing of palm sugar syrup without additional sugar, so that the saccharose contained is natural only from palm sap and with the presence of phenolic compounds, palm sap syrup can be categorized as syrup functional so it is very beneficial for health. Sugar palm syrup which has a commercial syrup viscosity of total soluble solids 70.

This study aimed to verify the influence of partial dehydration of "Niagara Rosada" grape clusters in physicochemical quality of the pre- fermentation must. In Brazil, during the winemaking process it is common to need to adjust the grape must when the physicochemical characteristics of the raw material are insufficient to produce wines in accordance with the Brazilian legislation for classification of beverages, which establishes the minimum alcohol content of 8.6 % for the beverage to be considered wine. Therefore, given that the reduction in the water content of grape berries allows the concentration of chemical compounds present in its composition, especially the concentration of total soluble solids, we proceeded with the treatments that were formed by the combination of two temperatures (T1-37.1ºC and T2-22.9 ºC) two air speeds (S1: 1.79 m s-1 and S2: 3.21 m s-1) and a control (T0) that has not gone through the dehydration treatment. Analysis of pH, Total Titratable Acidity (TTA) were performed in mEq L-1, Total Soluble Solids (TSS) in ºBrix, water content on a dry basis and Concentration of Phenolic Compounds (CPC) in mg of gallic acid per 100g of must. The average comparison test identified statistically significant modifications for the adaptation of must for winemaking purposes, having the treatment with 22.9 ºC and air speed of 1.79 m s-1 shown the largest increase in the concentration of total soluble solids, followed by the second best result for concentration of phenolic compounds.

Blueberry is a fruit consumed fresh and as an ingredient in formulations such as jam, juice, and wine. Wine is a widely consumed beverage and produced from different berries and fruits. Blueberry wine contains bio-compounds that could have a beneficial effect on health. Therefore, this study aimed to optimize blueberry wine by two response variables (total soluble solids and fermentation time) to obtain the highest alcohol percentage, pH, and lightness. In order to optimize the fermentation process, a central composite design was used. The optimized blueberry wine was obtained at total soluble solids of 25°Brix and fermentation time of 16 d. The optimized blueberry characteristics estimated were: alcohol percentage of 11.91%, pH of 2.98, and lightness (L*) of 26.22, and the optimized blueberry characteristics experimental were: alcohol percentage of 11.93±0.02%, pH of 2.97±0.01, and L* of 25.42±1.80. The optimized blueberry wine had a total phenolic content of 360.27±18.09 mg of gallic acid equivalents L-1, total anthocyanin content of 46.27±3.66 mg cyanidin-3 glucoside L-1, antioxidant capacity by ABTS and DDPH assays of 1,539.8±92.18 and 1,688.07±57.57 mM Trolox equivalent L-1, respectively. The results suggest that optimized blueberry wine can be considered a drink with potential health applications.

This study was done to analyze the effect of chemical preservatives on watermelon juice. Ten different samples of pasteurized watermelon juices with different chemical preservatives, termed as T1, T2, T3, T4, T5, T6, T7, T8, T9, T10 , were made which were stored at 4 - 15°C for three months. T1 and T2 were rejected soon due to spoilage. pH decreased from 5.094 to 4.017 and minimum pH content was reduced in T10 (7.87%), while maximum in T1 (57.55%). The total soluble solids (TSS) increased from 17.460% to 18.980% with maximum in T1 (51.67%) and minimum in T7 (4.88%). Reducing sugar was increased from 15.650 to 17.500% with maximum in T10 (18.22%) and minimum in T2 (5.90%).  Minimum microbial load was observed in T10 (0.20cfu/ml) and maximum in T1 (>24 cfu/ml) in case of coliforms; minimum in T10 (78×105 cfu/ml) and maximum in T1 (258×105 cfu/ml) in case of total viable bacteria and same results (minimum in T10 and maximum in T1) were shown in case of fungal count. E.coli was found in T1, T2, T3 and T4 and some bacteria was found in SS agar (especially Salmonella) in T1, T2, T3 and T5. Among all the treated juice samples T10 was most effective in maintaining the sensory and nutritional quality during storage.Keywords: © 2013 JSR Publications.

An experiment was conducted to evaluate the changes in the chemical properties of banana fruits and their shelf life as influenced by different postharvest treatments. There were two varieties viz. Amritasagar (VI) and Sabri (V2) and seven storage treatments viz.: control (open space, 30±2ºC) (T0); perforated polyethylene, 30±2ºC (T1); non-perforated polyethylene, 30±2ºC (T2); benzyl adenine (BA 30 ppm, 30±2ºC) (T3); gibberellic acid (GA3 150 ppm, 30±2ºC) (T4); benzyl adenine (BA 30 ppm, 15°C ) (T5) and gibberellic acid (GA3 150 ppm, 15°C) (T6). A factorial experiment was laid out in the Completely Randomized Design (CRD) with three replications. Data were recorded on titratable acid content, total sugar content, reducing sugar content, non-reducing sugar content, total soluble solids and pulp pH. Among the chemical parameters, total soluble solids (TSS) and pH of pulp increased while titratable acidity decreased during storage in all the treated and untreated banana fruits. Among the treatments gibberellic acid (GA3 150 ppm, 15°C) treatment exhibited the best storage performance. The treatment combinations of Sabri with gibberellic acid (GA3 150 ppm, 15°C) showed the longest shelf life (16.25 days), whereas the lowest shelf life was in Amritasagar with control (open space, 30±2ºC) treatment combination (6.78 days).The Agriculturists 2014; 12(2) 06-17

Pineapple is a food rich in vitamins, antioxidants and bromelain, but because it has high water content it becomes a highly perishable fruit. Hibiscus is a plant with flowers rich in phytochemicals that can be used as an ingredient to add value to processed products. The objective of this work was to prepare mixed jams using pineapple with hibiscus extract at different concentrations and to characterize the physicochemical properties of the jams produced. Experimental design was completely randomized with four replicates. The treatments consisted of three concentration levels of hibiscus extract (5, 10 and 15%) in pineapple jelly (50:50). Analyzed physical-chemical characteristics were: water content, water activity, ash, lipids, total sugars, reducing and non-reducing sugars, vitamin C, total titratable acidity, pH and total soluble solids. It was found that increasing concentrations of hibiscus in the formulations significantly influenced resulting jam composition. Increasing hibiscus concentration reduced the total sugars content and increased ascorbic acid content, acidity, total soluble solids and ash, as well as total anthocyanins and flavonoids contents. Among the jams produced, the formulation with 15% hibiscus was distinguished by its high content of ascorbic acid, flavonoids and anthocyanins. The addition of hibiscus to pineapple jelly improves the nutritional and functional value of the resulting jams, so it can be considered a high potential ingredient for this type of product.

Diversification of food is the key factor for enhancing physicochemical properties, nutritional status and consumer satisfaction. Hence, mixed fruits jam was developed from coconut and pineapple pulps in varied ratios (1:1, 3:1 and 1:3). Moisture, lipid, protein, fiber, ash and total carbohydrate contents of different jam samples varied significantly (p≤0.05) and found values in the ranges 26.78-29.15%, 4.12-10.81%, 0.56-1.13%, 1.51- 3.12%, 0.30-0.37% and 62.69-67.91% respectively. Storage stability of the jam samples was analyzed for 6 months keeping under refrigerated (4°C) and room (30°C) temperatures. Physicochemical properties such as total soluble solids, acidity, pH and reducing sugar content were evaluated at 2-months intervals. The parameters were changed variedly due to compositional variances, packaging materials and storage temperatures. Total soluble solids, acidity and reducing sugar content increased gradually while pH declined upon extension of storage period. Sensory properties for color, taste, flavor, texture and overall acceptability of jam samples were tested where sample with pineapple and coconut in the ratio 3:1 showed the best result than others. Samples were also analyzed for yeast and mold count at the end of the storage period and positive result was found in case of samples packed in plastic containers kept under room temperature. The study yields diversified jam samples with better nutritional and sensory properties with satisfactory shelf life.

Massive changes in physicochemical composition and color variation usually occur in fruits during maturation and ripening. This study is conducted to implement an image processing system and develop a maturity color chart of banana. Actually, natural ripening color is different than impose ripening. Maturity color chart will help the consumer when it will be in the packet of banana. The earliest physiological maturity (stage-1) was marked as the stage when the flesh color was olive green and the pulp turning yellow and the subsequent maturity stages determined whenever changes the color as stage-2 (green smoke), stage-3 (apple green), stage-4 (olive drab), stage-5 (yellow) and stage-6 (golden rod) color. For each of the maturity stages, physical (peel color, firmness, and weight loss) and biochemical (anthocyanin content, carotenoids content, titrable acidity, pH, total soluble solids, ascorbic acid, reducing sugar, non-reducing sugar, and total sugar) maturity indices were determined. We had classified the maturity stages of banana based on the RGB (Red, Green, and Blue) and HSV (Hue, Saturation and Value) values. Average, median, minimum and maximum values were used in this study. After completing the qualitative analysis of RGB and HSV values we found the correlation coefficient of RGB and HSV values. The red color (R) values of bananas would increase when stages increase and the hue (H) means the pure color of bananas decreases when stages increase. Therefore, we can say that maturity stages of bananas mainly depend on R and H values. In case of Amritsagor banana at stage-6 (golden rod) color, TSS (Total Soluble Solid) (2.1%), TA (Titrable Acidity) (0.96%), pH (5.2), sugar (1.25%), vitamin C (2.5 mg/100g), reducing sugar (1.04%), non-reducing sugar (0.2%), anthocyanin (0.55 mg/100g) carotenoids (0.38 mg/100g) and at stage-1 (olive green) color, pH (6.8), vitamin C (8.75 mg/100g) are significantly highest. The results show that as maturation progressed, firmness decreased gradually and flesh color turned olive green to golden rod with ripening. Total soluble solids increased while TA (Titrable acidity) gradually increased with maturity. The results revealed that, there is a significant relationship between nutritional value, firmness and fruit skin color. So, the fruit of stage-1 (olive green) is suitable for harvesting and stages-6 (golden rod) color is suitable for consumption. Actually this message for grower/ owner or who would like to harvest and consumer. Fruit is banana, to observe the change of color keep it at room temperature. Neither artificial nor chemical system used here. Each and every box will carry the real maturity color chart.J. Bangladesh Agril. Univ. 16(2): 293-302, August 2018

With a look to apple industrialization in Argentina, apples were analyzed to evaluate them as a raw material. The 9 more important varieties harvested in 1967 were: Red Delicious, Granny Smith, Rome Beauty, Delicious, Black Wine-sap, King David, Yellow Newtown Pippin, Jonathan, and Golden Delicious. They were analyzed for: specific gravity, pH, total acidity (as malic acid), soluble solids, total sugar, reducing sugar, pectin, tannin, ascorbic acid, moisture, starch (qualitative test), dry matter, and texture. Analysis were made on fruit harvested at the picking date, and on samples from the same tree held 1, 2, 4 and 6 weeks (the latter for Delicious and Red Delicious only). All analyses were completed within 24 hr of harvesting time. A review is made of similar data from other countries. Argentinian apples are similar to those grown in other countries.
