CHAPTER - 1
INTRODUCTION Fruits are among the perishable commodities, but are animportant source of nutrients in the human dietaries. Due to their highnutritive value they make significant nutritional contribution to humanwell being. Fruits in the daily diet have been strongly associated withreduced risk of some form of cancer, heart disease, stroke and otherchronic diseases. Fruits form an essential daily supplement since the early times,providing nutritionally valuable components. They are source of anumber of essential vitamins and minerals that cannot be found in theother foods or they may contain higher levels of these nutrients thanother foods. The most significant contribution that fruits make to ourdiet is by adding vitamins to the diet, because they are a rich source ofβ- carotene, vitamin B3, vitamin B6 and vitamin E. Fruits have highwater content and also contains minerals like sodium, potassium, ironand other elements in small amounts. That is the reason why mostfruits can be eaten without any undesirable effect on health. Fruits contain organic acids in the form of acid salts of calcium,potassium and sodium. These acids are oxidized in the body and leave abasic residue in the blood. For this reason, fruits assist in maintainingthe acid-base balance of the blood. These acids include citric acid,found in citrus fruits, cherries and strawberries; malic acid found in
apples, berries, cherries and some citrus fruits; oxalic acid in manyfruits. Like vegetables, fruits also contain dietary fiber, which our bodyneeds to cleanse and rid itself of refuse and toxins. The dietary fiber isalso needed to keep bowel movements regular, lower cholesterol levels,prevents constipation, bowel cancer and other illness of the bowel andintestine such as diverticulosis. Apart from being rich in vitamins and minerals, fruits containantioxidants that protect cells by neutralizing free radicals. Fruits alsocontain phytochemicals and unsaturated fatty acids. Fruits are not onlya good food but also a good medicine. Since ages, scientists and horticulturists have been explaining theuse of several fruits for the betterment of mankind. India is the thirdlargest producer of fruits in the world with an annual production of 33million tones, which is 8 per cent of world’s production. India producesalmost all tropical and exotic fruits because of the varied climaticconditions. Most fruits are seasonal crops and perishable in nature. In agood season there may be a local glut, but because of insufficienttransport facilities, lack of good roads and poor availability of packagingmaterials, the surplus cannot be taken quickly to the nearby markets inurban areas. Moreover the surplus cannot be stored for sale in the off-seasons because of inadequate local cold storage facilities. Thisabundance of production is not fully utilized and about 20-30 per centof the produce gets wasted. To avoid these surplus losses, fruits areprocessed in various products and are preserved.
One such method for the preservation of fruits is the pickling,which is one of the ancient methods. Pickling is the lactic acidfermentation of fruits, which combines salting of fruits to selectivelycontrol the microorganisms and fermentation process to stabilize thetreated fruit. Lactic acid fermentation is carried out by lactic acidforming bacteria, which are generally present in large numbers on thesurface of fresh fruits. These bacteria can grow in acidic medium and inthe presence of 8-10 per cent salt, whereas the majority of theundesirable microorganisms are inhibited in such conditions. Lacticacid bacteria are most active at 30°C, so this temperature should bemaintained as far as possible in the early stages of the pickle making.Lactic acid fermentation has been associated with the therapeuticvalues besides the antimicrobial activity imparted to fermented fruitsdue to the production of various antimicrobial compounds. Duringpickling process, the salt makes brine solution and the soluble materialslike fermentable sugars and minerals diffuse out of the tissues of thefruits. The sugars serve as food for lactic acid bacteria which convertsthem into lactic acid and other acids. Apart from contributing certaindesirable flavour characteristics to the fruits, pickling also prolongs theavailability period of the produce by processing at a relatively low cost. Pickles are the products obtained as a result of the picklingprocess. Pickles are good appetizers and add to the palatability of ameal. Pickles are not the main meal itself but used with the main mealor some course to increase the pleasure of eating. They stimulate the
flow of gastric juices and thus help in digestion. Pickles are preparedwith salt, vinegar, oil or with a mixture of salt, vinegar, oil and spices.Pickles are commonly made in homes as well as commerciallymanufactured and exported. India has a large variety of picklescommonly known as ‘achar’ in Hindi. Mango pickle is very well knownin Indian market and relished by all, but there are some fruits which arehighly nutritious and yet there pickle is not available in the market, onesuch fruit is ‘Apple’. Apples are the pomaceous fruit of the apple tree (Malusdomestica) in the family Rosaceae. Apples are low in calories; 100 g offresh fruit slices provide only 50 calories. They contain no saturated fatsor cholesterol; but are rich in dietary fiber which helps to preventabsorption of dietary LDL cholesterol in the gut. The dietary fibers alsohelp to protect the mucous membrane of the colon from exposure totoxic substances by binding the cancer causing chemicals in the colon.Apple fruit contains good quantities of vitamin C and β- carotene.Vitamin C is a powerful natural antioxidant. Consumption of foods richin vitamin C helps to develop body resistance against infectious agentsand scavenge harmful, pro-inflammatory free radicals from the body.Apples are rich in antioxidant, phytonutrients, flavonoids andpolyphenols. The important flavonoids in apples are quercetin,epicatechin, and procyanidin. The total measured antioxidant strengthof 100 g apple fruit is 5900 TE.
Apples are also good in tartaric acid that gives tart flavour. Applefruit is a good source of B-complex vitamins such as riboflavin, thiaminand pyridoxine. Together these vitamins help as co-factors for enzymesin metabolism as well as in various synthetic functions inside the body.Apple also contains small amount of minerals like potassium,phosphorus and calcium. Potassium is an important component of celland body fluids and helps in controlling heart rate and blood pressure;thus counters the bad influences of sodium. Apple occupies around 40 per cent of total area under fruit andaccounts for 90 per cent of the total production of fruits in Jammu &Kashmir. The area under apple cultivation accounts for 87,000 hectareswith an annual production of 9.29 lakh metric tons (2009-10). But dueto unavailability of adequate packaging and processing facilities in thestate, 30 per cent of the total fruit produced gets wasted. Also,inadequate marketing facility and lack of investment and integration inthe marketing chain and value addition in the supply chain isnegligible. This leads to a huge wastage of the crop in a good season.To avoid the losses due to wastage of apples, the apple fruit can beconverted to a value added product by the pickling process. Apple pickle can be prepared by the use of various spices likefenugreek, cumin, turmeric, fennel, black pepper, rai powder, red chillipowder, salt and mustard oil. For preparation of apple pickle, the applepieces are given a pre treatment prior to pickling to stop the browningprocess. Keeping in view the nutritive value and health benefits
provided by apple fruits, pickle prepared from apples will have a goodnutritional and medicinal value.
AIMS AND OBJECTIVES• To prepare and standardize the recipe for apple pickle.• To study the physico-chemical characteristics of the final product.• To check the acceptability of the product.
CHAPTER – 2
REVIEW OF LITERATUREA review of previous study on the health benefits of apples, fenugreekseeds, turmeric, black pepper, nigella seeds, cumin seeds, fennel seedsand red chilli has been done and is compiled as under:Chipault et al. (1952) made a systematic study on antioxidant contentof red chilli. The antioxidant content was found by super critical fluidextraction of red chillies.Kurti (1969) showed that flavonoids called phloridzin found only inapples protects postmenopausal women from osteoporosis and alsoincreases bone density.Agrawhal (1979) showed that nigella seed oil increases the milk outputof breast feeding mothers.Amplis (1981) conducted a research on the cholesterol loweringproperties of apples. In his research he found that apples had pusheddown the blood cholesterol of the patients by 30%. The applesmanipulated the blood so that good HDL cholesterol went up and thedestructive LDL cholesterol went down. He suspected that pectin- asoluble fiber contained in apples caused the reduction in the bloodcholesterol of patients.
Sharma, Raghuram and Rao (1990) studied the effect of fenugreek seedson blood glucose and serum lipids in type I diabetes patients. Theirstudy showed that diabetic patients when given fenugreek seeds in dietshowed a reduction in fasting blood sugar test and an improved glucosetolerance test.Chakravarty (1993) conducted a study to see the possibility ofcrystalline nigella seeds being an inhibitory agent on histamine. Dr.Chakravartys study found that the crystalline nigellone present innigella seeds inhibits protein kinase C, a substance known to trigger therelease of histamine. In addition, his study showed that crystallinenigellone decreased the uptake of calcium in mast cells, which alsoinhibits histamine release.Alexandrovich et al. (2003) studied the effect of fennel seed oilemulsion in infantile colic. Their study showed that fennel seed oil hasbeen shown to reduce intestinal spasms and increase motility of thesmall intestine.Egan et al. (2004) reported that curcumin; a major constituent ofturmeric corrects a cystic fibrosis defect which is caused by themutation in gene encoding the cystic fibrosis transmembrane regulator.Amin et al. (2005) showed in their studies that fenugreek seeds havechemopreventive action against breast cancer. This was the first studythat suggested the chemopreventive effects of fenugreek seeds againstbreast cancer.
Lui (2005) concluded eating apples “may be an effective strategy forcancer protection”. His studies also suggest that apples can preventlung, prostate, pancreatic and other digestive cancers.Veeriah et al. (2006) reported that apple flavonoids inhibited coloncancer cell growth and significantly modulated expression of genesrelated to xenobiotic metabolism.Hsu and Cheng (2007) studied the therapeutic benefits of cumin. Theyconcluded from their study that cumin has antioxidative, anti-inflammatory and anticancerous effects on the human body.Zhang (2008) showed that quercetin found in apples prevents lungdamage in smokers. His findings were especially interesting becausetobacco smoking is the major risk factor for lung cancer. He suggestedthat the naturally occurring chemicals may be working to reducethe damage caused by smoking.Carroll et al. (2009) reported that curcumin present in turmeric shows ameans of reducing breast cancer risk among women undergoinghormone replacement therapy during menopause.Masoumi et al. (2009) reported that curcumin may help to protectagainst Alzheimers disease. In the study nine Alzheimers patients and
four people without the disease, investigators determined that acombination of curcumin and vitamin D may prompt the immunesystem to clear the brain of amyloid β (a substance that forms the brainplaques associated with Alzheimers disease).Keith (2010) studied the health benefits of black pepper. His studyprovides evidence that black pepper may have health benefits,particularly in enhancing digestive tract function. There is suggestiveevidence that piperine, which is present in black pepper may havebeneficial effects on nervous system.
