Merang, part of rice straw, waste generated from rice harvesting process, is abundantly available in Indonesia. Incomplete burning of merang generates carbonized rice straw (CRS). This study is aimed to identify selected minerals (K,Ca, Na and Fe) contents of CRS using AAS, and to evaluate the effect of differentconcentrations (1.5-3%) of CRS addition on the pasting properties of rice:sago mixflour (55:45), and on the black color intensity, texture, and sensory properties of dawet gel. CRS contains potassium (20599.91±776.44 ppm), calcium (307.58±70.71), sodium (30.59±1.03ppm) and iron (1079.98±20.75 ppm). Despite the temperature similarity, pasting properties of mixed flour such as final viscosity and peak time are significantly decreased in response to CRS addition. Increase in CRS concentration results to significant increase of the black color intensity and texture of dawet gel. Sensory evaluation suggests that most of the panelists prefer the color and firmness showed by dawet gel with addition of 2.5% of carbonized rice straw. This result suggests that CRS could be an interesting new food ingredient for increasing black color intensity and texture of food product.

Melon (Cucumis melo L.) cv. Gama Melon Parfum (GMP) is the new cultivar from cross-breeding of Natsuno Omoide (NO3) female parent and Miyamauri (MR5) male with phenotypic characteristics that is prominent such as very strong pleasant aroma when ripe. The physiological characteristics will be changed which have an impact on the formation of volatile compounds during fruit development. Therefore, the profile of strong volatile aroma compounds during fruit development to is critical to be identified. The volatile compounds analysis was performed on fruits harvested at 7, 14, 21, 28, and 35 days after pollination and storage at -20°C. Gas chromatography-mass spectrometry (GC-MS) was used for volatile identification. The results showed some volatile compounds changed during fruit development consisted of 8 esters, 2 alcohols, 1 acid, 3 terpenoids, and 3 hydrocarbons. The profile of volatile compounds was dominated by esters, followed by alcohols and acid respectively. Interestingly, the characteristics of the volatile compounds can differentiate between the ripe stage and unripe stage using principal component analysis. The findings of this study can be used to improve the quality aroma of GMP.

The mushroom agroindustry has a profitable business opportunity for farmers because it is easy to cultivate, needs short planting time, and does not require extensive planting land. Moreover, the price of post-harvest products is quite high. To face increasingly intense competition, mushroom agroindustry actors need to implement strategic management to increase business competitiveness. The purposes of this study are to identify a business model using the business mode canvas (BMC) approach, analyse the internal and external factors of mushroom agroindustry and formulate alternative business development strategies using SWOT analysis. The result shows that the business model of mushroom agroindustry viewed by nine elements of BMC. By SWOT analysis, mushroom agroindustry has internal strength in its business that is on clear consumer segmentation (0.650). The weakness is anticipating the fewer consumers’ enthusiasm toward healthy food products (0.500). The opportunity of mushroom agroindustry is optimizing the online market (1.200). The threat is competitors from other food products (0.525). Some alternatives of developing the business are based on hold and maintain position consists of four combined strategies: developing and increasing product quality (SO), increasing promotion and services (ST), marketing the products by social media (WO), and evaluating the quality of business relationship (WT).

Coffee leaf tea is made by drying coffee leaves in an oven at 70oC for 4 hours. The quality of coffee leaves tea does not only depend on the process of making tea but also the way the tea is brewed. There were 2 types of brewing techniques investigated in this study, namely infusion and decoction. Response Surface Methodology (RSM) was conducted to optimize the brewing time and temperature for obtaining highly functional coffee leaves tea with optimum total phenolic content (TPC) and antioxidant activity. The Rate-All-That-Apply (RATA) sensory technique was then applied to determine the sensory characteristics of coffee leaf tea. It was observed that optimum tea quality brewed by hot infusion technique was obtained at 80.03oC for 10.4 minutes while that of decoction technique was obtained at 95.38oC for 5.7 minutes. The coffee leaves tea brewed by decoction technique have higher total phenolic content, tannin and antioxidant activity than that of infusion technique (p-value<0.05). Even though the functional properties of coffee leaves tea such as total phenolic content and antioxidant activity, tended to be lower than that of commercial black tea, the coffee leaves tea is still more superior than that of tea leaves that prepared as the process of coffee leaves tea. The coffee leaves tea that brewed by both decoction and infusion techniques were well accepted by consumer panel.

Microbial contamination and fat oxidation may cause physical and chemical changes that can reduce the quality of broiler meat. The objective of this study was to determine the ability of casein chitosan edible coatings in maintaining the quality of broiler meat stored in certain storage time under refrigeration (8 oC), in terms of water activity (Aw), cooking loss, organoleptic properties (i.e. color, aroma and possible deviations), physicochemical properties (i.e. moisture content, water holding capacity/WHC, pH, lipid content, color), Total Plate Count (TPC), and microbial properties (i.e. Staphylococcus aureus, Escherichia coli, and Salmonella sp.). The materials used were broiler breast fillets and casein chitosan edible coating. The research was conducted using a Completely Randomized Design (CRD) based on 5 variations in storage time treatments i.e. at 0 h; 24 h; 72 h; 120 h; and 168 h in 4 replications. Edible coating casein chitosan on broiler meat under storage showed significant on Aw, WHC, pH, lightness, TPC, S. aureus, and E. coli. The application of casein-chitosan as an edible coating could be suitable to assure the safety of food products such as chicken meat at the range of storage time studied.

In East Java, the production of clove leaf oil refinement is developed by businesses owned by rural people. The processing operation is simple and start-up investment is low. The clove leaf oil manufacturing procedure uses old leaves that fall naturally in the dry season, these are found to be better preserved, mature and environmentally friendly. East Java rural distillers use a single boiler for steam, water and raw materials in order for the investment costs to remain low. This study aimed to research the use of appropriate technology for the clove leaf distillation process and how to increase clove oil both in yield and quality. Two different tests were conducted; introducing a leaf crusher as a raw material and replace the old chamber material with stainless steel. There are three grades of raw materials; rough leaves, smooth leaves, and non-crushed leaves. After the clove leaves were crushed, they are distilled in the new stainless steel boiler with an aim to compare the oil yield and quality. The result from the crushed leaves treatment indicates there are different volume condensates produced from the same volume of raw materials, 128.2 litres from smooth grade and 117.2 litres from rough grade leaves. The highest percentage of clove oil (15.07%) results from rough grade crushed leaves. By replacing the chamber material with stainless steel positively affects the brightness of the clove oil. In conclusion, these two tests, to improve appropriate technology for clove oil production, can increase both yield and oil brightness, and subsequently improve the competitive advantage and future aspiration of the product.

The further processing of coconut shell pyrolysis into liquid smoke has been developed in recent years. However, the common technology by directly condensing the smoke has many impurity compounds which decreases the yield of liquid smoke produced. Hence, in this study the cyclone separator was applied to increase the quality of physicochemical content in coconut shell-liquid smoke (CS-LS) grade C. The physical parameters analyzed were yield, pH, density and color. The chemical parameters was analyzed by GC-MS. The result showed that CS-LS processing with cyclone separator was able to increase the total yield into 3.33%, with better color, pH and density compared to the CS-LS produced using common method (direct condensation). The application of cyclone separator was also able to increase the phenolic compounds (97%), alcoholic compounds (92%), cycloalkene compounds (91%) and also decreased the benzoic acid, carbonyl and ester up to 100% compared with common method for CS-LS grade C production.

The result showed that CS-LS processing with cyclone separator was able to increase the total yield into 3.33%, with better color, pH and density compared to the CS-LS produced using common method (direct condensation). The application of cyclone separator was also able to increase the phenolic compounds (97%), alcoholic compounds (92%), cycloalkene compounds (91%) and also decreased the benzoic acid, carbonyl and ester up to 100% compared with common method for CS-LS grade C production.","PeriodicalId":325722,"journal":{"name":"Advances in Food Science, Sustainable Agriculture and Agroindustrial Engineering","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116355248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cattle manure contains high organic matter, so that this material is commonly used as plant nutrients in a form of organic fertilizer. In order to get a better understanding on the use of cow manure, the objectives of this research are (1) to determine the influence of liquid waste and solid livestock as fertilizer on soil quality and (2) to study the effect of both liquid and solid fertilizer on coffee plant growth. In this research, Completely Randomized Design (CRD) was employed as a research design, while data analysis was conducted using ANOVA. The F statistical test was applied to measure whether all independent variables could influence the dependent variable by using 5% and 1% (Alpha) degrees. The results showed that one time application of livestock wastewater improved C-organic chemical properties, N, P, CEC, Ca and Mg while soil chemical properties of pH, K, Na decreased. Two times application of livestock liquid fertilizer treatment improved soil chemical properties pH, N total, Ca, Mg and saturation bases. As for solid waste, one time treatment increased chemical properties of pH, C organic, N total, Ca and saturation of the base. The two times treatment could improve soil chemical properties of pH, N. total, P, Ca, Mg, base number and base saturation. Liquid waste fertilizer also found to provide significant effect on plant height and coffee plants quality. Additionally, (3) solid waste (compost) was found to have a significant effect on plant height, plant height rate and number of buds.
