Anthocyanins and catechin are natural antioxidants presented in many plants . Lepisanthes alata (Blume) Leenh is a plant with fruit that ripens to an intense red. This coloring suggests high polyphenol content. However, limited information available regarding the or other antioxidant content this its suitability as food additive. The purpose of research was determine total phenolic, monomeric anthocyanin, catechin, epicatechin epigallocatechin gallate content, DPPH radical scavenging...

Abstract This study was conducted to observe the characteristics of sodium carboxymethyl cellulose (Na-CMC) made from bacterial pineapple peel waste obtained results community business activities. Na-CMC with various hydroxide concentration treatments. The alkalization process NaOH is critical start carboxymethylation produce CMC. manufactured concentrations in range 5, 7.5, 10, 12.5, and 15%. resulting then analyzed for quality using several parameters such as water content, NaCl purity,...

Plastic waste poses a significant environmental challenge due to its non-biodegradable nature, emphasizing the need for sustainable alternatives like bioplastics from natural resources. This study develops and characterizes bioplastic films made carboxymethyl cellulose (CMC) derived bacterial synthesized using pineapple biowaste. Pineapple underwent fermentation produce cellulose, which was chemically modified into CMC. Films were fabricated CMC solutions with varying glycerol concentrations...

This study examines the impact of pineapple core storage duration on properties bromelain enzyme produced. Bromelain is a protease used in many applications agro-food, pharmaceutical and cosmetic industries. aimed to determine changes activity during at various durations (0, 12, 24, 48 hours). was extracted by mixing juice with 90% ethanol, followed separation process filtration. The results showed that peaked 12 hours then loss significantly after 24 hours. caused pH, increased water...

This study aims to determine the antioxidant activity and essential oil content in a mixture of butterfly pea flower herbal tea encapsulated siam orange peel extract with best characteristics. The design used this was completely randomized (CRD) five treatments three replications. given were A (without mixing extract), B (mixing 1%), C Siamese 2%), D 3%), E 4%). research data analyzed statistically using ANOVA continued Duncan's New Multiple Range Test (DNMRT) at 5% level. results showed...

Betalains were extracted and analyzed from Red Pitaya Peel (Hylocereus polyrhizus). For this extraction, ethanol/water solvent systems used. The observation such as UV-vis Spectrophotometric identification, total betalain content, HPLC-DAD analysis, antioxidant capacity, antibacterial activity acute toxicity screening test employed for the character of main pigments presented in extracts. Maximum pigment concentration (73 mg/100 g fruit) was obtained. Four compounds detected by analysis with...

This research aimed to assess the effectiveness of nanocellulose biofilter (NCB) made from pineapple peel waste reduce number microbes in water. Further processing cellulose nata de pina into nano size was proposed, then transformed a filter membrane. Three types NCB were developed: bacterial acetate membrane, membrane with TiO2 treatment, and graphite nanoplatelet treatment. These NCBs used several water sources Padang City, West Sumatra Province. The filtering process carried out using...

The effect of temperature on changes in raffinose family oligosaccharides (RFOs) and isoflavones contents during cultivation period soybean sprouts was investigated to enrich the basic knowledge production method sprout with high functionality. In this experiment, were cultivated at 10°C, 15°C, 20°C, 25°C, or 30°C, concurrently respiration rate measured by flow-through using gas chromatography. RFOs such as stachyose, then determined performance liquid amount found significantly dependent...

Objective: This study aimed to investigate the effects of sodium metabisulfite soaking on quality durian seed flour and its application in producing dakak-dakak (West Sumatraʼs traditional snack).Materials Methods: The concentrations used this were: A (0.7%), B (0.6%), C (0.5%), D (0.4%) E (0%, as control).The parameters observed include water content, ash protein fat carbohydrate sulfite residue, yield, gelatinization temperature, absorption, color, oil absorption product acceptance by...

Role of raffinose family oligosaccharides (RFOs), sucrose and lipid in respiration metabolism during soybean seed germination were investigated to determine appropriate method for producing sprouts containing high amount RFOs. Soybean soaked into 50 μM 1-deoxygalactonojirimycin (DGJ), which is a specific α-galactose inhibitor, 90 minutes before after preparation phase (GPP). without DGJ treatment was used as control. The growth rate, respiratory quotient, fatty acids saccharides contents...
