The production of vegetables and fruits is at a high rate but the major challenging task is the postharvest handling and processing of the products. Approximately 20–30% of the production is being wasted due to a lack of proper postharvest management. Many developments were made to reduce this wastage such as cold chain development, different storage structures, some drying methodologies to promote the shelf life of produce. But all these systems need to be improved and utilized commercially. The losses still occur due to a lack of sound knowledge on the chemical nature of products and different management techniques (e.g., drying, cooling, blanching). Therefore, the successful design of the cooling, packing, storage transport, and drying processes of fresh food requires linking materials sciences, fluid dynamics, mechanical deformation, food chemistry, and process control.

In Nepal maize is produced and consumed in significant amount. Summer maize contributes about seventy percent of the total maize production but has high possibility of fungal infection before and during harvest. Traditional practices of post harvest operations and outdoor storage structures are supportive for insect infestation, mold growth and development of mycotoxins. Several studies have shown that the incidence of afl atoxin contamination in maize is high and average prevalence is about 50%. Department of Food Technology and Quality Control (DFTQC), a governmental body reports that about 20% of the maize samples contain aflatoxin greater than the ML (20ppb) as set by the government. On the basis of available data, a simple deterministic exposure assessment for total afl atoxin via maize shows that the situation is alarming and needs immediate attention. In Nepal aflatoxin concern in maize demands a need to further investigation and a risk assessment for revealing the existing situation. This review aims to fi nd out the current situation of aflatoxin contamination in maize produce of Nepal and provide possible ways to reduce the contamination.

The purpose of the paper is to gain an insight into the current status of farmers' awareness and practices towards maintaining the postharvest cold chain. The related hypotheses are developed and tested. The major findings include- marginalized and small farms, literacy and poor awareness level are the main causes for the backwardness of Indian farmers. Also, lack of funds forces farmers to ignore the use of cold storage. Further, multi-intermediaries and fluctuating consumer prices result farmers in not getting fair share of the consumer rupee. One of the major challenges in front of fresh food industry in India is to reduce postharvest losses across the chain through increasing awareness level of famers towards cold chain, building market information systems to assist farmers in decision-making and improving food safety and quality of farm produce available in the market.

The consumption pattern of Indian consumers is fast diversifying due to rapid internationalization of dietary patterns, rising double income families and ever-increasing health consciousness. As a result, consumers have shifted significantly from consuming merely food grains to vegetables and fruits. This change has accelerated the demand for more and more horticultural produce, both raw and processed. Tomato is one of the major horticulture crops consumed world widely. The consumption of tomato products increased over the past few years. According to the report of WPTC the increase in the consumption of processed tomato indicates a slow shift of consumers away from fresh products towards processed products. The demand for tomato is high in Europe, North America, Italy, U.S.A, Russia and Germany. The demand of the processed tomato is more most of the tomato is consumed as sauce for pizza and pasta. Tomato is one of the most widely grown vegetable crops in Uttarakhand and Tarai region of North India. In Uttarakhand 119742 metric tons of tomato is cultivated in an area of 9360.75 hectares (NHB, 2019). The farmers of Uttarakhand prefer tomato cultivation as the agro-climate condition is favourable. Moreover, wide spread use of tomatoes for different food preparations such as soups, salads, pickles, chutney, paste, puree, ketchups, junk and ready to eat food has increased demand for tomatoes. In Uttarakhand, the generated produce is not efficiently supported by the existing market infrastructure. The entire supply chain of tomato is laden with inefficiencies: poor transportation facilities, lack of cold chain facilities, lack of processing units, poor connectivity from farm to market, huge post-harvest losses and large no. intermediaries. The grower’s still practice traditional cultivation methods remain unaware of consumer needs, preferences and prevailing market prices. This causes large fluctuation in consumer prices and low quality of non-standardized produce. This is a double whammy as farmers realize poor prices on the one hand whereas consumers pay exorbitant prices on the other hand. Horticulture crops being high value crops are important in enhancing income for the farmers besides creating on farm and off farm employment. It is important for India to leverage its diverse agro-climates and distinct seasons, which makes it possible for farmers to grow a wide variety of horticulture crops. The objective of this paper is to design an efficient supply chain model which can better price realization of farmers and also ensures timely, adequate, quality supplies to consumers at the right prices.

Abstract The need for a shift toward healthier and more sustainable diets is evident and is supported by universalized standards for a “planetary health diet” as recommended in the recent EAT-Lancet report. At the same time, differences exist in tastes, preferences and food practices among diverse ethnic groups, which becomes progressively relevant in light of Europe’s increasingly multi-ethnic cities. There is a growing tension between current sustainable diets standards and how diverse ethnic resident groups relate to it within their ‘culturally appropriate’ foodways, raising questions around inclusion. What are dynamics of inclusiveness in migrant food practices? And what does this mean towards the transition to healthy and sustainable food? We study this question among Syrian migrants with different lengths of stay in the Netherlands. Our theoretical framework is based on practice theories, which emphasize the importance of socio-material context and of bodily routines and competences. We use qualitative methods, combining in-depth semi-structured life-history interviews with participant observation. Our findings indicate that inclusiveness takes different forms as migrants’ food practices and the food environment change. Regarding health and sustainability in food practices, understandings and competences around particularly fresh food change over time among both short- and long-term migrants, replacing making things from scratch with seasonal products with buying more processed products and out-of-season vegetables and fruits. We conclude that the performances of food practices and their configurations in food environments and lifestyles are dynamic and cannot unequivocally be interpreted as in- or exclusive, but that a more nuanced understanding is required.

The rapid development of cold-chain transportation necessitates consumers to present high requirements on safety and freshness of fresh food in recent years. The quality and taste of fresh food can be monitored and controlled through the intelligent packaging technologies and new food packaging materials such as time-temperature indicators (TTIs), Radio Frequency Identification (RFID), biological composites and polymer nanocomposites. Based on different packaging materials, indicators and sensors are employed in food packaging for real-time detection of information about freshness, temperature, microbiological, and shelf life of products in the supply chain. Wide varieties of packaging materials are suitable for providing intelligent and smart properties for food packaging, such as oxygen scavenging capability, antimicrobial activity, and recording the thermal history. Due to the special properties of prepared materials, TTIs are used to point out the remaining shelf life of perishable products throughout the supply chain. Compared with others, they have the advantages of low cost, small size and convenient indication. Additionally, the TTIs can effectively solve food quality and safety problems caused by temperature fluctuation in supply chain. Since the irreversible color change of TTIs, the food safety situation would be shown intuitively. Currently, the TTIs were widely used in application of food packaging by providing safety information. However, the application is also accompanied with some deficiencies such as the accuracy of monitoring, migration of toxic substances, stability and expensive cost etc. This review will deeply discuss the preparation of various types of TTIs based on different package indicating materials with a particular emphasis on how to improve their accuracy and stability, control the migration of toxic substances and to develop new TTIs.
