Chinensis, commonly known as Bok Choy, is a nutrient-rich vegetable with substantial antioxidant content. Therefore, this study aimed to evaluate the effect of hydropriming and bio-nutri-priming using Sandwich compost leachate on seed germination, SPAD reading, and dry matter accumulation in 280 dwarf variants of Bok Choy seeds sourced from Green Eagle. The experimental process involved hydropriming with tap water, bio-nutri-priming using 0.2% Sandwich compost leachate, and a control group cultivated in soil without priming. A complete randomization design (CRD) with three replications assessed seed germination performance, SPAD, root and shoot dry matter, and root-to-shoot ratio. While there was no significant difference in the germination percentage (88.35±1.13%), the entire priming seeds exhibited a 2-day peak germination period, compared to 3 days for the non-priming counterparts. Bio-nutri-priming seeds showed faster median and mean germination times due to enhanced nutrient uptake. They further displayed high SPAD readings, suggesting a lack of toxic compounds. The dry matter production of all treated Bok Choy was similar because administered treatments did not interfere with plant growth and development. Therefore, applying bio-nutri-priming using Sandwich compost leachate positively affected seed germination performance, warranting its recommendation as a seeds priming solution.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139198827","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}

Nowadays, crafting ice cream at home has become convenient through the use of premixes, often added with chocolate flavor. Therefore, this study aimed to conduct a sensory profiling evaluation and panel performance test on chocolate ice cream mix powder products. Sensory analysis was used to analyze product quality, differences, and similarities, with humans as measurement tools. This study also employed a group of trained and reliable panelists for product testing. The sensory profile and performance of several chocolate ice cream premixes on the market were assessed with the quantitative descriptive analysis (QDA) method. The premix products considered were those registered with BPOM, and the analysis encompassed physical characteristics (overrun and melting rate) and sensory evaluation. Meanwhile, the panelist selection was based on ISO 8586 Year 2012. Panelist performance evaluation was conducted to determine their proficiency in sensory analysis, and the results obtained were analyzed using sensehub and XLSTAT. The QDA test results showed that PT XYZ chocolate ice cream premix was superior in all sensory attributes. However, the weaknesses identified in this premix were related to low overrun value and higher melting rate. The panelist performance evaluation indicated that panelists P1 to P9 needed retraining in discrimination skills. This is because although the panelists had a relatively good consistency, their discrimination ability showed insignificant results.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139204020","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}

To address this limitation, diversification of nori with other ingredients such as moringa leaves becomes imperative. Moringa leaves are used due to their green color, high nutritional content, and easy availability. A binder and gel-forming agent containing high amylopectin are also needed to achieve a high-quality and compact nori texture. Suweg is an underutilized gel-forming agent with high amylopectin content. Therefore, this research aimed to characterize moringa leaf nori supplemented with suweg starch (Amorphophallus campanulatus) at concentrations of 0%, 1.25%, 2.5%, 3.75%, and 5%. The results indicated that suweg starch influenced tensile strength, thickness, water content, water activity, ash content, and protein, as well as sensory tests for color, aroma, brittleness, and taste, while crude fiber content was not affected. Based on sensory, physical, and chemical tests the best nori was achieved with the addition of 1.25% suweg starch. The result of characterization of this nori included a tensile strength of 355.90 gf, thickness 0.0145 mm, water content 15.50%, water activity value 0.645, ash content 15.30%, protein content 9.88%, and crude fiber of 2.18%. The sensory evaluation showed that the nori had a green color (3.1), a subtle leafy aroma (3.1), slightly broken (2.9), and a slightly bitter taste (3.2) with preference scores categorized as preferred (3.5), slightly favored (3.3), favored (3.7), and moderately liked by the panelists (score 3.3), respectively.

The substantial accumulation contributes to environmental pollution since its resilience against microbial degradation poses a significant challenge. Furthermore, the utilization of bioplastics as a biodegradable substitute presents a viable strategy for diminishing reliance on synthetic plastics. Starch emerges as a prevalent primary component in the fabrication of bioplastics, owing to its array of merits including renewability, cost-effectiveness, non-toxicity, and facile degradability. The application of nanomaterials to bioplastics is believed to accelerate the degradation of bioplastics. Therefore, this study aimed to identify the characteristics of nanomaterial from porang (Amorphophallus muelleri) and bioplastic. The method included the extraction of porang nanomaterial through a specified water-to-porang ratio (2.5:1) followed by sonication (50 W, 75 minutes). The formulation of bioplastics involved the amalgamation of corn starch, porang nanomaterial, and glycerol. In addition, the chemical properties of porang nanomaterials included 41.41% starch content, 13.49% amylose, 7.87% ash, and 2.52% calcium oxalate. The particle size of porang nanomaterials was distributed from 603.7-952.1 nm with an average 722.6 nm crystalline structure containing calcium oxalate. The bioplastic had the form of a thin brown layer with a thickness value ranging from 0.23-0.39 mm. This research was expected to provide new information related to the essential characteristics of nanomaterials from porang and its potential application in solving environmental issues caused by synthetic plastics.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139205930","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}

Conjugation mode is frequently intricate and poses challenges when scaling up for large-scale production. Consequently, this investigation sought to optimize the conditions of the WPC-pectin conjugation process using Response Surface Methodology (RSM) in conjunction with Box-Behnken design (BBD). The experimentation was executed employing a cabinet dryer, incorporating both wet and dry heating procedures to yield a WPC-pectin conjugate exhibiting favorable functional properties. The independent variables investigated encompassed pectin concentration (ranging from 0 to 1%), pH (ranging from 6 to 8), and drying time (ranging from 2 to 6 hours), The measured responses encompassed the emulsion stability index (ESI), emulsifying activity index (EAI), and solubility. Analyzing the experimental data underwent scrutiny for model sufficiency through diagnostic plots, and a second-order polynomial equation was fitted through multi-response regression analysis, resulting in a high coefficient of determination (R 2 ) value. The most effective parameters were identified as a pectin concentration of 0.49%, pH 6.7, and a drying duration of 4.12 hours, yielding a peak ESI of 452.267 minutes, EAI measuring 49.95 m 2 g -1 , and solubility reaching 48.09%. Further experiments were conducted to validate these outcomes, and the presence of the Maillard reaction was confirmed using Fourier Transform Infrared Spectrum (FTIR). The et-dry method demonstrated efficacy in producing WPCpectin conjugates with commendable functional properties.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139199798","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}

Besides nutritional and functional aspects, it is also crucial to consider organoleptic properties. Therefore, this study aimed to characterize nutritional value (proximate), physicochemical properties, organoleptic and Glycemic Index (GI) of mixed rice. A total of 10 mixed rice formulas, ranging from F1 to F10, and consisting of white rice, brown rice, black rice, aromatic rice, sticky rice, black-eyed peas and mung beans, were determined. These samples were analyzed for proximate, total phenolic compounds, pasting properties, and organoleptic tests (hedonic and ranking tests). Furthermore, 3 selected formulas based on the previous test were then evaluated for GI, and Glycemic Load (GL) was calculated. The results showed that adding black-eyed peas and mung beans (F9 and F10) increased the protein content of mixed rice while higher proportion of black or brown rice (F3 and F4) enhanced the fat content. The amylose content was decreased due to higher proportion of sticky rice (F6 and F8). Based on the hedonic test, the F1-F6 formula had a favorable rating. The ranking results indicated that F9 was better than F10, while F1 and F6 was the best among F1 to F4, as well as F5 to F8. Considering the constituent materials, F1, F6, F9 and commercial low GI rice were selected and tested for GI, and the test results showed 48.2, 54.7, 78.0, and 60.3, respectively. As a result, F1 and F6 have the potential to be developed as mixed rice because they have good nutritional value, physicochemical and organoleptic properties, as well as low GI.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139198766","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}

This phenomenon is caused by the imbalance between antioxidants and free radical production necessitating the need for exogenous antioxidants. Golden bladderwort ( Utricularia aurea ) plant may have the potential as a source of antioxidant. Therefore, this study aimed to investigate the effect of extraction temperature on the polyphenol compounds and the antioxidant activity of the golden bladderwort plant. The dried powder from the plant was extracted using 70% ethanol at 30, 45 and 60 ºC, with each treatment repeated three times. The antioxidant activity was analyzed by using the 2,2-diphenyl-1-picrylhydrazyl method. The results showed that the yield of extraction was 1.34% (30 ºC), 4.00% (45 ºC) and 12.48% (60 ºC). The total polyphenol and flavonoid contents found at 60ºC were 50.80 mg QE/g dried sample and 60.01 mg QE/g dried sample, respectively. Furthermore, the antioxidant activity was calculated in half-maximum inhibitory concentration (IC 50 ), and the values obtained were 0,38 mg/mL (45 ºC), 0,35 mg/mL (30 ºC) and 0,11 mg/mL (60 ºC). These results indicated that temperature of extraction affected the level of polyphenol contents and the antioxidant activity of the golden bladderwort extract. The high extraction temperature (60 ºC) emerged as the most optimal condition for extraction with effective antioxidant activity. Therefore, the results can be used as a reference for future investigations involving the extraction of polyphenol compounds from golden bladderwort as a source of natural antioxidants.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139199050","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}
