Effect of mass and size husk ash adsorbent on acid number and free fatty acid of virgin coconut oil (vco) produced by enzymatic process

Virgin Coconut Oil (VCO) is an oil produced using low temperatures. Efforts to maintain and improve the quality of VCO with papain enzymatic manufacturing method followed by the provision of husk ash adsorbent. The use of papain enzyme as much as 1.5% w/v with an incubation temperature of 40°C 24 hours was effective in reducing acid numbers. The husk ash adsorbent which was treated in an oven at 120°C 2 hours was effective in improving the color quality of the VCO. Variations of husk ash were adsorbent size (60, 80, and 100) mesh and mass (15, 20, and 25) grams. The sample that has been mixed with adsorbent is stirred with a magnetic stirrer at 300 rpm 1 hour then separated by centrifuge at 1000 rpm 1 hour and ends with VCO filtering with filter paper to separate the remaining adsorbent from the oil. Samples were tested for acid number and free fatty acid content. The results show that the smaller the size of the adsorbent and the more the amount added gives a positive effect on decreasing the acid number and free fatty acid content. Production of VCO has low environmental impact because it uses low energy.

Pengaruh Volume Air dan Lama Waktu Putaran Terhadap Kualitas VCO (Virgin Coconut Oil)

Coconut plant (Cocos nucifera L.) is one of the industrial plants which plays an important role for the survival of the Indonesian nation. Because of that, the coconut tree is called The Tree of Life. Coconut also produces a processed product that is popular lately, namely Virgin Coconut Oil (VCO), which scientifically has VCO health benefits, including reducing the risk of cardiovascular disease [1], anti-diabetic and antioxidant [2], preventing premature aging and healing wounds [3], and many other benefits. (Septiany Christin Palilingan & Meity Pungus, 2018). This study aims to determine the effect of water volume and spin time on the quality of VCO. This study used a factorial Completely Randomized Design (CRD) consisting of 2 factors, namely the length of time factor (A) and the ratio of water addition ratio (K). Factor A consists of three levels, namely: A1 = 10 minutes, A2 = 20 minutes and A3 = 30 minutes. The K factor consists of 3 levels, namely: K1 = 1 kg of grated coconut: 2 liters of water, K2 = 1 kg of grated coconut: 3 liters of water and K3 = 1 kg of grated coconut: 4 liters of water. The results showed that the spin time factor had no significant effect on the yield, specific gravity, viscosity, acid number, water content and pH. The water volume factor had a significant effect on the yield and water content but had no significant effect on the specific gravity, viscosity, acid number and pH.

Impact of thermal and nonthermal process intensification techniques on yield and quality of virgin coconut oil

Virgin coconut oil (VCO) is valued for its nutraceutical potential. The focus of this research was to assess the effect of selected thermal and nonthermal pre-treatments on the yield and quality of subsequently wet-extracted VCO.

Pembuatan VCO (Virgin Coconut Oil) Dengan Penambahan Ekstrak Jeruk Nipis (Citrus aurantifolia swingle), Bawang Putih (Allium Sativum), dan Ragi Tape (Saccharomyces Cerevisiae) Secara Fermentasi dan Pengasaman

The manufacture of Virgin Coconut Oil (VCO) which is done by heating is considered less effective because the quality of VCO produced is not good and also requires expensive production costs. Virgin Coconut Oil (VCO) is a processed product from coconut that has many benefits if processed properly, which is one of the reasons VCO has a promising target market, so further research needs to be done on the process of making VCO so that it can produce quality products. This study aims to determine the effect of the addition of garlic extract (Allium sativum), lime (Citrus aurantifolia swingle), and yeast tape (Saccharomyces cerevisiae) on Virgin Coconut Oil (VCO) products and to know the process of making VCO simply by fermentation and acidification to save production costs. Fermentation is the process of making VCO using the help of bacteria, in this study used Saccharomyces cerevisiae, while the manufacture of VCO by acidification is the manufacture of VCO with the addition of acidic substances, in this study used lime. The processing of VCO by fermentation or acidification in this study does not go through a stirring process, but is allowed to stand for 8-10 hours until three layers are formed, namely water, oil, and blondo which will then be separated to obtain the desired product (VCO). The addition of garlic extract in the process of making VCO by fermentation is thought to be able to eliminate the rancid odor in the resulting product, this is proven to be true after the results obtained from the VCO manufacturing process show that VCO given the addition of garlic extract does not smell rancid but a little smell of garlic mixed with delicious savory coconut. Overall, making VCO by fermentation using tape yeast, adding garlic extract, and acidification using lime produces VCO products that are clear in color and do not smell rancid so that the results of VCO can be categorized as good. In addition to the conventional process that is often done, making VCO can also be done by fermentation and acidification as done by researchers. In the process of making VCO by acidification, researchers need to ensure that the pH is in an appropriate state.

Green Technology On The Virgin Coconut Oil Production Using Enzyme From Pineapple Waste

Virgin coconut oil (VCO) is widely used for the pharmaceutical and cosmetic industries. The high lauric acid content is very beneficial in the pharmaceutical field, such as for antiviral and antibiotic. Also, this VCO is very useful for cosmetic formulation. VCO production can be done by several methods, which are chemical, physical, and enzymatic methods. By the increase of VCO demand at the national and international levels, this study proceeded with the production of VCO using an enzymatic way that was efficiently conducted and environmentally friendly. The purpose of this research is to study the enzymatic process of VCO production by using pineapple waste, including pineapple crowns, pineapple fruit skins, pineapple leaves, and pineapple trunks. The pineapple waste used contains the enzyme bromelain to break down protein emulator in coconut milk cream. From the number of experiments with variations in substrate volume and temperature, the optimal VCO formation was obtained at 50oC with the ratio between the substrate and enzyme material was 9 to 1. The quality of VCO was evaluated as water content, free fatty acid concentration, and saponification numbers. Based on the evaluation results, the quality of VCO produced was similar to the standard of APCC, SNI, and Codex.

Proposed Physicochemical Standards for the Identity and Quality Characteristics of Philippine Virgin Coconut Oil

The growth of the virgin coconut oil (VCO) industry over the past few years has highlighted the need to improve VCO standards to promote better quality and detect adulteration. The Philippine National Standard for VCO (PNS/BAFPS 22:2007) has three groups of parameters – identity characteristics, quality characteristics, and contaminant limits. It has only one identity characteristic – the % fatty acid composition, which is based mainly on Codex Stan 210-1999. However, because the fatty acid composition does not distinguish VCO from refined, bleached, and deodorized coconut oil (RBDCO), additional methods are needed to differentiate VCO and RBDCO and to detect adulteration. This study proposes a new spectrophotometric measurement at 278 nm, which can accomplish both objectives. Regarding VCO quality characteristics, PNS/ BAFPS 22:2007 states that VCO should be colorless and sediment-free. However, some VCO products may have light yellow color due to the method of production, and sedimentation naturally occurs below the freezing point of VCO, which is 25 °C. New methods are proposed to address the concerns of color and sediment. Because the Codex methods are optimized for vegetable oils with long-chain unsaturated fatty acids, some methods need to be adjusted for the analysis of VCO, which is composed mainly of saturated medium-chain fatty acids. These standards and methods can be adopted by regulatory agencies and guide the industry to ensure quality VCO.

Potency of Bentonite and Pelawan Wood Active Charcoal as Virgin Coconut Oil (VCO) Purity Improvements Through Free Fatty Acid Binding

Virgin Coconut Oil (VCO) is pure coconut oil produced from fresh coconuts and does not contain additional chemicals. VCO has a high lauric acid content which acts as an antibiotic, namely antiviral, antibacterial and antiprotozoal so that VCO can increase the human body's resistance to disease or viruses. Free fatty acid (FFA) levels will significantly affect the quality of VCO. The requirement for maximum fatty acid content in VCO to be suitable for consumption is 0.2%. One of the efforts to reduce the free fatty acid levels of VCO is to use adsorbents such as activated charcoal and bentonite. This study aims to determine the effect of bentonite and activated charcoal of pelawan wood (Tristaniopsis merguensis) enhancers of VCO purity. The results showed that the best reduction in free fatty acids was using bentonite and activated charcoal of wood-furnaced pelawan, which was 0.265, while the best turbidity test result was 0.193.

Utilization Of Activated Charcoal From Nutmeg Shell Waste As An Adsorbent To Improve The Quality Of Virgin Coconut Oil (VCO) Fermentation Method
