Presented by Saurav Tuteja, this document discusses factors that contribute to post-harvest loss of fruits and vegetables and methods to control such loss. Primary causes of loss include mechanical damage during handling and microbial or environmental spoilage. Secondary causes are things like inadequate facilities for harvesting, transport, storage and marketing. Control methods include proper cultural practices, harvesting, packaging, pre-cooling, transportation, marketing, controlled atmosphere storage, ionizing radiation, and waxing to extend shelf life and minimize waste of perishable agricultural produces.
Management of Post-Harvest Losses in Fruits and Vegetables
Fruits and vegetables are the most perishable agricultural produce and the post-harvest loss of these is tremendous. Producers have to suffer a huge economic loss due to lack of proper understanding about causes, nature of loss, proper preservation methods, their transportation, and marketing techniques. This paper suggests the methods of handling the fruits and vegetables after their harvest so as to reduce the loss to the minimum and obtain maximum returns from them.
Fresh fruits and vegetables are perishable and highly prone to these losses because they are composed of living tissues. These tissues must be kept alive and healthy throughout the process of marketing. These are composed of thousands of living cells which require care and maintenance.
Advances in drying and dehydration in Fruit Crops
Drying and dehydration of fruits is an important method of preservation that reduces water content and inhibits microbial growth. There are several key points made in the document:
1) Sun drying is the oldest method but modern methods using controlled conditions better maintain quality. Pre-treatments like washing, peeling, slicing, and blanching prepare fruits for drying.
2) Drying reduces weight and volume for easier storage and transport while concentrating nutrients. Dried fruits retain most vitamins and minerals.
3) Different dryers exist like sun, solar, spray and freeze drying but each has advantages and disadvantages related to costs, drying time, and quality effects. Precise temperature and humidity control in dehydration

The chemicals when added interfere with the cell membrane of the microorganisms, their enzyme activity or their genetic mechanisms. They also act as antioxidants. The common chemical preservatives permitted are
1. Benzoic acid (including benzoates) Sodium benzoate is a salt of benzoic acid and is used in preservation of colored fruit juices and squashes
2. Sulphur dioxide (including sulphites): Potassium meta-bi-sulphite is used as a source of sulphur dioxide when it is added to the juice or squash. When used in fruits with deep colours like blue grapes, jamun, watermelon it bleaches the colour and hence in such cases benzoic acid is desirable.
3. Organic acids and their salts: Foods can be preserved by adding lactic, acetic, propionic, citric acids and their salts. Nitrates and nitrite compounds are used to preserve meat and fish products. It gives desirable colour, flavor and discourages the growth of micro-organ-isms. It also prevents toxin formation by the microorganisms in food.
PROCESS
Selection of fruits and vegetables
(i) Fruits and vegetables should be absolutely fresh.
(ii) Fruits should be ripe, but firm, and uniformly mature. Over-ripe fruits should be rejected because they are infected with microorganisms and give a poor quality product. Unripe fruits should be rejected because they generally shrivel and toughen on canning.
(iii) All vegetables except tomatoes should be tender.
(iv)Tomatoes should be firm, fully ripe and of deep red colour.
(v) Fruits and vegetables should be free from dirt. (vi) They should be free from blemishes, insect damage or mechanical injury.
INTRODUCTION
Canning is defined as preservation of foods in hermetically sealed containers and usually implies heat treatment as the principal factor in prevention of spoilage.
Canning was invented by Nicholas Appert in 1910 so also termed as Appertization.
Foods that are canned
Low acid foods: Meat, fish, poultry, dairy fall into a pH range of 5.0 to 6.8. This large group is commonly referred to as the low acid group.
Acid foods: With pH values between 4.5 and 3.7. Fruits such as pear, oranges, apricots and tomatoes fall in this class.
High acid foods: Such as pickled products and fermented foods. The pH values range from 3.7 down to 2.3, also Jams and Jellies are in this classification.
PRINCIPLE OF CANNING
Destruction of spoilage microorganism within a container by means of heat.
Lecture 2.ppt
The document discusses the structure of fruits, vegetables and flowers. It begins by defining fruits as the edible product of a plant consisting of the seed and its envelope, especially when juicy and pulpy. Vegetables are grouped as seeds/pods, bulbs/roots/tubers, and flowers/buds/stems/leaves. Flowers are the seed-bearing parts of a plant surrounded by petals and sepals.
It then explains the key differences between fruits and vegetables. Fruits are generally sweet and consumed raw, while vegetables are less sweet and consumed cooked. Biochemical constituents like water, carbohydrates, proteins, lipids, minerals, vitamins and pigments determine the composition and quality of fruits
Principles and methods for food preservation
The document discusses principles and methods for food preservation. It explains that food preservation prevents spoilage by removing microorganisms, inactivating enzymes, and removing insects and rodents. Common preservation methods include dehydration (removing moisture through sun drying), lowering temperature through refrigeration and freezing, increasing temperature through pasteurization and sterilization, and using preservatives like salt, sugar, and chemicals. Specific preservation techniques are provided for items like methi, potato chips, peas, and various fruits and vegetables.

Food industrial waste from fruit and vegetable processing industry
Fruit and vegetable processing waste represents a loss of valuable biomass and nutrients. It is rich in organic matter, phytochemicals, and compounds with nutraceutical properties. However, it is often poorly disposed of, leading to environmental pollution problems. This waste can be converted into useful products like enzymes, ethanol, and biocolors. Some examples of fruit and vegetable wastes that can be utilized include orange peel for dietary fiber powder, potato peel for fibers, carrot pomace for carotenoids and fibers, and apple pomace as a source of pectin and minerals. Proper utilization of this waste can provide additional income for farmers and manufacturers while sustaining renewable resources and providing healthy ingredients for consumers.
Postharvest changes in fruits and vegetables
Post-harvest activities include harvesting, handling, storage, processing, packaging, transportation and marketing of agricultural products. After harvest, fruits and vegetables undergo various physiological changes like respiration, ripening, and senescence. Respiration rate varies between climacteric and non-climacteric fruits. Cell wall components like pectin degrade during ripening. Ripening is a genetically programmed process involving several enzymes that cause changes in color, softening, acidity, and flavor. Optimal temperature and humidity are required for ripening. Storage extends shelf life by slowing post-harvest changes through temperature and humidity control and modified atmosphere packaging. Factors like water loss, respiration, and microbes affect storage life.

What is Oxygen absorbers.pdf
An oxygen absorber is primarily designed to prolong the food's shelf-life and prevent changes in the food's colour, taste and odour. It even prevents the packed food from becoming rancid and the growth of aerobic microorganisms such as fungi. An oxygen absorber comprises powered irons, which work to eliminate oxygen within a confined environment. Therefore, an oxygen absorber absorbs the excess oxygen and effectively reduces the aerobic environment to 0% oxygen.

Nuts and Dry fruits often turn rancid if not stored properly.docx
- 1. Nuts and Dry Fruits Frequently Turn Rancid If Not Stored Properly Nuts and dry fruits such as Cashew nuts, Almonds, Walnuts, Peanuts, Pistachios, Melon seeds, and raisins are rich sources of many vital nutrients and vitamins to humans; vitamins like A, C & E are present in rich quantities in these nuts, which can get oxidized due to oxygen and consequently nuts can become devoid of these vitamins. Dry fruits and Nuts are also rich in natural fat and oils. Thus, if not protected well during storage, because they can lead to oxidation in the presence of air penetrating into the packaging. However, protective measures should be taken while packaging the nuts and dry fruits, without losing quality over time. Nuts and fruits are dry compared to foods with higher oxygen and moisture content. Still, surroundings are always a big threat to the penetration of air inside the packets, making the contents available for degradation in the presence of oxygen and moisture. Further, being rich in lipid content, nuts lead to deterioration by lipid oxidation. Therefore, they must be preserved with oxygen absorbers which not only inhibit the oxidation of lipids but also prevents the growth of mould, mildew and microorganisms in the presence of oxygen and moisture. The growth of microorganisms can further cause physical and chemical changes in nuts and dry fruits, leaving them unsuitable for consumption. All these issues can be addressed by introducing oxygen absorbers in nuts and dry fruit packaging. The oxygen absorber for dry fruit helps in bringing the oxygen level down to 0.01 %. By absorbing oxygen, it helps create a nitrogen environment that is helpful for the long-term storage of food. Sorbead India markets oxygen absorbers specially manufactured for nuts and dry fruits as dry foods need the kind of oxygen absorbers that contain deoxidizing agents and enhance oxygen absorbers' action in the low water environment in the food and ensures the preservation of such foods in the best possible way. Dry fruits and nuts preserved with oxygen absorbers manufactured for 'regular use' may not be found fresh all the time as it is ineffective in lowering the oxygen level in dry fruits. Sorbead India caters to the needs of the dry fruits and nuts packaging industry with its customized oxygen absorbers packets that show enhanced action in the presence of the deoxidizing agent. It markets USFDA-certified oxygen absorbers that maintain the freshness of packaged nuts and dry fruits and increase the shelf-life of packaged products.
