Study of Pineapple Peelings Processing into Vinegar by Biotechnology ABSTRACT | This study aimed to reduce post-harvest losses of pineapple local variety egbenana by the transformation of juice into vinegar through biotechnological process.Vinegar was produced through two successive fermentations: alcoholic and acetic fermentations. The alcohol fermentation was carried out at 30°C using yeast. Biomass, pH and Brix were evaluated daily during the fermentation. Acetic fermentation was carried out at 30°C using an acetic bacteria strain isolated from pineapple wine previously exposed to ambient temperature (28°C) for 5 days. Biomass, pH and acid levels were monitored each 2 days. The performance of acetic bacteria isolated was also assessed by studying their glucose and ethanol tolerance. The study allowed the isolation of yeast coded Saccharomyces cerevisiae (LAS01) and an acetic bacteria coded Acetobacter sp. (ASV03) both occurring in the pineapple juice. The monitoring of successive fermentations indicated that the pineapple juice with sugar concentration of 20 Brix, seeded with 106 cells of Saccharomyces cerevisiae (LAS01) for alcoholic fermentation for 4 days and afterwards seeded with 106 cells of Acetobacter sp. resulted in 4.5 acetic degree vinegar at Brix 5.3% and pH 2.8 for 23 to 25 days. The study of glucose tolerance of the strain of Acetobacter sp. showed that the growth of acetic bacteria was important in a juice with high concentration of sugar. However, the concentration of ethanol did not effect on the acetic bacteria growth. These results enabled on one hand to improve the manufacturing technology of vinegar from fruits and on the other hand to produce a starter of yeast and acetic bacteria strains for this production. | |

INEPO ÇEVRE PROJE OLİMPİYADI FATİH KOLEJİ (FATIH COLLEGE) ISTANBUL, TURKEY 1-4 JUNE 2008 Avril Rodiel Bries Quezon City Science High School (Regional Science High School for NCR) REPUBLIC OF THE PHILIPPINES- CUMHURIYET FİLİPİNLER School Year 2007-2008 Mr. Noel Pablo Diaz Research Adviser Abstract: On average, 435,000 metric tons of pineapples are produced annually in the Philippines, which is one of the country’s leading commercial fruit products. However, there are a lot of unused excess parts of the pineapple, notably the peelings, which are considered as waste and contribute to the country’s garbage problem. There is a global oil crisis, as the demand for petroleum increases each year while our supplies are rapidly being depleted. Bioethanol, a principle biofuel, is a natural alternative to gasoline. One solution to both dilemmas is to produce bioethanol from pineapple plant peelings. This will be made possible by extracting the glucose content of the peelings and fermenting it through the process of Simultaneous Saccharification and Fermentation (SSF) using the yeast sample.

...Department Kidapawan City THE FEASIBILITY OF PINEAPPLE (ANANAS COMOSUS) PEEL AS AN ALTERNATIVE VINEGAR CHAPTER I: INTRODUCTION A. BACKGROUND OF THE STUDY A Pineapple, is a fruit wherein you have to peel off the peelings to eat it, like any other fruits. We, the researchers, chose this as their project to prove that Pineapple peelings have other uses. We, the researchers, also noticed that the families in our country are very practical nowadays. Instead of throwing the peelings away, many families can earn something from it by using our experiment. They can produce a product and maybe start a business or they can produce it for their own use. We, the researchers, wanted to prove that nothing in this world is useless and peelings count as useful materials too, and can somehow help people to use their creative minds to make things possible out of such wastes. B. STATEMENT OF THE PROBLEM Our country is experiencing economic crisis and many Filipinos do not have stable jobs. Our problem in waste management also has a huge impact on why the researchers chose this study to begin with. The wastes in market says it all. The following problems that this study wants to answer are the following: * Does the peeling of pineapple (Ananas comosus) can be made as vinegar? * Can this study help to reduce the waste in the environment? * Is pineapple vinegar more affordable than a commercially sold vinegar? * Is pineapple vinegar has more taste than a......

Physochemical Properties of Pineapple Extract

...PHYSIOLOGICAL STUDIES OF THE FRUITS OF THE PINEAPPLE [ANANAS COMOSUS (L.) MERR.] WITH SPECIAL REFERENCE TO PHYSIOLOGICAL BREAKDOWN ERSTON V. MILLER Received July 17, 1950 Introduction Physiological breakdown of the fruits of the pineapple [Ananas comosus (L.) Merr.] is characterized by a darkening of the flesh of the fruitlets, beginning near their attachment to the core in a region an inch or two above the base of the fruit. The-disorder progresses upward and outward, subsequently involving all of the fruitlet except the ovary and a layer approximately one quarter inch deep below the skin. Only in advanced stages do the surface of the fruit and the core become involved. Hence in most fruits there may be no external symptoms of the disorder. Severe cases of physiological breakdown are frequently discovered in pineapples that appear normal and attractive from the exterior. The disorder is not a form of over-ripeness as is true of "internal breakdown" of apples. One of the commonest causes of physiological breakdown is exposure of the fruits to relatively low temperatures. The disorder has been observed in Florida in the fruits that were induced to ripen during the winter months by forcing the bloom with acetylene gas during "off season." Physiological breakdown has been reported to occur under similar conditions in Australia (3). Also pineapples harvested during the summer months may develop breakdown during storage or transit if holding temperatures......

Factors Affecting Demand of Pineapple in Malaysia

...ECO 740 ECONOMIC ANALYSIS MASTER IN BUSINESS ADMINISTRATION “FACTORS AFFECTING DEMAND OF PINEAPPLE IN MALAYSIA” PREPARED FOR: Prof Madya Dr Rosita Suhaimi PREPARED BY: Azarudin Bin Berudin (2013803912) Cecilia Amid (2013859584) Daphne Gayle (2013278394) INTRODUCTION Global price hikes in food has created a global crisis that affects both developed and developing countries. Initial causes of the price spikes included unseasonable droughts in grain producing nations which can be attributed to climatic change and rising oil prices. The rise of oil prices exacerbated costs of fertilizers and transportation of food. The increased farming use in biofuels, growing consumer demand, global population growth and structural changes in trade and agricultural production has also lead to the price increase of food and made it unaffordable for many people. In Malaysia, the Agrofood Policy (2011-2020) was formulated to ensure food security, enhance global competition, increase farmers’ income, ensure agro-food sector’s sustainable growth and boost food production to meet growing population demand. The period is a critical time as Malaysia plans to achieve an advanced high-income economy (in line with the 10th Malaysia Plan, 2011-2015) with consumers’ need for quality, safety, nutrition, functionality and environmental sustainability. Demand for local fruits is expected to increase at a growth rate of 2.3% annually from 2.7 million metric tonnes in 2010 to 3.3 million metric tonnes by......

...pineapple A Commodity system analysis Overview of the Commodity Photo from www.markmaranga.com/camp-phillips-del-monte-pineapple-plantation-in-bukidnon/ A. Technical Description Pineapple (Ananas comosus) is a perennial crop grown for its fruits and used as a fresh and processed product. World production is about 13.7 million tons fresh fruit.(FAOSTAT, 2001). The origin of the pineapple is still uncertain but the Parana-Paraguay Basin has been considered as a possible area. For good growth pineapple requires mean daily temperatures of 22 to 26°C with an optimum of 23 to 24°C. Mean daily maximum and minimum temperatures of 30 and 20°C respectively for the whole growing period are considered optimum. Temperatures below or above this range affect fruit quality or the acid and sugar content. The crop is grown between 31°N and 34°S, primarily in regions with high relative humidity. A combination of optimum temperature and high humidity results in soft, large leaves and juicy fruits, low in acid content. Fruits ripening in periods with cool temperatures and low radiation levels, e.g. in winter or at high altitudes, are of inferior quality because of poor shape for canning. Requirements for canning are: a cylindrical shape, fruit eyes of a relatively shallow surface and a small fruit core in relation to the fruit. Pineapple can grow on a wide range of soils but a sandy loam texture is preferred. Optimum soil pH is 4.5 to 6.5. The soil should have a low lime content. The...

Pineapple Express

...PINEAPPLE EXPRESS Joshua D. LeBel SOC 120 Amanda Eaton 10 November 2013 PINEAPPLE EXPRESS Legalize marijuana! That is where I stand, and I plan on convincing you to join me in the fight to legalize a harmless, useful, and medically beneficial plant. Throughout the last 70 years or so marijuana has gotten a bad reputation as being a drug that will make you crazy, has no benefits, and will cause you to hurt the people around you. Before this time for over 200 years cannabis has been used to make everything from paper to cars. Legalizing marijuana will help our nation expand its economy and allow us to provide more from within rather than import from outside sources. Even though marijuana is seen as gateway drug that will lead to the use of harder drugs like heroin or LSD, I believe it should be legalized because medical marijuana has helped sick people where no other pharmaceutical drug could. Cannabis has been used for thousands of years. The oldest known uses have been recorded as far back as 2737 B.C. as medicine by Emperor Shen Neng of China (Advanced Holistich Health, 2013). The Chinese would later use hemp as to make clothes, shoes and rope and even paper. By the sixteenth century hemp was widely distributed in Europe where it was cultivated for fiber and the seeds were cooked with barley or other grains and eaten. In 1537 Discorides named the plant Cannabis sativa and wrote of its use for cordage as well as its medicinal properties [ (Ehrensing, 1998) ]. Back...
