“…The number of processing mills increased from 170 units in 1959 to over 3500 units in 2008. Half a million people were employed in the Indian cashew industry and about 95% of them were rural women [2]. Of the cashew processing units, whereas the unorganized sector accounts for 54% and the organized sector accounts for 46%.…”

Purpose: In the Indian food processing sector, the cashew nut processing industry plays a critical role. Often, the cashew is considered as ‘both a poor person’s crop and a rich person’s meal.’ From the cultivators, traders, wholesalers, processors to supermarkets and retailers, the cashew processing sector is a vital source of income. Cashew processing is a labour-intensive sector that has always employed a significant number of rural women. The purpose of this study is to gain an in-depth understanding of the Cashew Processing Sector, its position in the world market, issues it is confronting and future prospects. While doing so, the present study attempts to examine the profile of the Indian Cashew Industry, including cashew processing and international trade. The quality, flavour and appearance of the Indian cashew kernels are highly respected in other nations and are consumed in more than 60 countries worldwide. Unfortunately, it was found that cashew production in India has been fluctuating in recent years. Despite its tremendous expansion, India’s cashew sector has been affected by low-quality cashew cultivated in some regions, which is mostly due to improper harvesting techniques, inadequate drying of the nuts and insufficient storage and warehouse facilities for dried cashew nuts. Design: For the purpose of analysis, this study used secondary data sources - Google Scholar articles, cashew industry and other related websites. Moreover, the literature is used to analyse the position of the industry within SWOC and PESTLE framework analysis. Findings: Based on the analysis, the cashew business needs certain incentives to attain a better rate of production and export growth in the future. Value: This paper emphases on the growth of the cashew industry in India in relation to its current status and future opportunities. Based on findings and their interpretation, the Indian Cashew Industry must prepare itself for the ever-increasing demand of the domestic market and contribute more effectively to the country’s economic growth. Paper Type: Case Study-based Research Analysis

“…The processing of cashew nut requires passing through a complex procedure of sun drying, roasting, shelling (breaking the outer layer), heating, and peeling of testa to become appropriate for human consumption. However, in parts of India like in Maharashtra stream roasting process is followed in small scale cashew nut processing industries (Mohod et al 2010). After roasting of the raw cashew, it releases caustic acid which can burn the skin, mouth and tongue if anybody consumes it directly.…”

In the cashew nut industries, women are mainly involved in cashew nut shelling and peeling activities. The objective of this study was to investigate the occupational health hazards and risk of injury faced by the women workers employed in the cashew nut processing industry. The study was conducted in four cashew nut processing industries: two each in Selsella and Mankachar blocks of Meghalaya and Assam, respectively. Ten female workers from each industry comprising a total of 40 workers, who have normal physiological characteristics, were selected randomly. RULA and QEC tools were used for the assessment of health hazards of the women workers. Discomfort survey was done to investigate the intensity of pain in different body parts. The results of the study showed that the workers of cashew nut industries were exposed to high occupational health and safety risk due to poor working environment, awkward working posture, repetitive and tedious job.

Drying is an important process in food preservation. In cashew processing industries cashew kernels are dried for easy peeling of the thin brownish sticky layer known as testa. For this it is necessary to reduce the average moisture content of 13% to 5%. Drying is achieved by direct and indirect methods like traditional open sun and using conventional energy through dryers. Due to control of the air properties in indirect drying cashew kernels can be dried at faster rate and can retain their quality. Air flow passages also play an important role in drying process. The objective of the study is to investigate experimentally the energy consumption for drying 1 kg of cashew kernel using electrically assisted heating and to evaluate the feasibility of active solar air dryer for drying in cashew processing industries. An electrical heat-assisted dryer (EHD) and an active solar flat plate collector air dryer (ASAD) systems are designed and developed using locally available materials. Both the systems are tested for reduction in moisture content with series of experiments. EHD is tested with three different drying chambers for optimum drying rate. In its final test drying chamber without baffle plates has resulted in reduction in moisture content to required level by 5% in three hours with drying rate of 2.8 kg/h against 6.5% and 6.8% in single tray version and four trays with baffle plate version. The drying efficiency of drying chamber is found to be 30.54%. In ASAD system the experimental results ensure the drying of cashew kernels within stipulated time of 6 hours with drying rate of 1.66 kg/h and energy consumption of 255 kJ against 270 kJ of electrical heater drying. The drying chamber exhibits an efficiency of 50.89%. The study suggests that the design is feasible to small, cottage industries for cashew kernel drying. The energy savings up to 3750 kJ per day for a batch of 15 kg is possible.
