ABSTRACT
Potatoes play an important role in ensuring food security. During the COVID-19 epidemic, consumption of processed potato products decreased, and consumption of fresh potatoes increased. China is the world's largest potato producer with more than 4.81 million hectares of area under potato production and 90.32 million metric tonnes of potatoes produced in 2018. This accounts for 27.36% of the world's planting area and 24.53% of the world's potato production. The proportion of potatoes processed in China was about 12% in 2017, mostly dominated by starch production. However, the recent policy of the Chinese government to popularise potato as a staple food has created new markets for processed potato products other than starch. A very few reports have analysed these future trends of the rapidly growing Chinese potato processing industry and its impact within and outside China. This paper provides an overview of the latest developments with a focus on processed potato products such as potato chips, French fries and dehydrated potatoes, and also, due to the unique Chinese diet culture, it highlights the need for more scientific research dedicated towards the development of novel potato-based healthy foods.
ABSTRACT
On November 24th, 2021 a case of a new viral variant of SARS-CoV-2 was reported by South Africa and Botswana to WHO, which later was designated as the variant of concern on 26th November 2021. It has around 60 mutations (50 non synonymous, 8 synonymous, and 2 non coding) as compared to the original parent strain of Wuhan. Different hypotheses have been put forward as an explanation for the origin like reverse zoonosis i.e. animal to human transmission, origin from an immune compromised patient or use of highly mutagenic drug like molnupiravir as treatment. A huge spike in cases around the globe is suggestive of a high rate of infectivity and transmissivity as compared to the previous known variants. With whatever cases have been documented so far, it is said that omicron causes mostly mild clinical illnesses and there is a less chance of hospitalization according to the clinicians. Among the reported cases, there were already vaccinated patients also. So there is a possibility that omicron might be able to evade the vaccine induced immunity due to a huge number of mutations (especially in the spike protein sequences). Until new vaccines specific to the pathogen are being developed, the coverage of the currently acceptable vaccines should be increased so that none is deprived of the mandatory doses and a third booster dose might help to reduce the chances of serious complications of this new strain beforehand. So an equal focus on the host and environment is required along with the pathogen.

Potatoes play an important role in ensuring food security. During the COVID-19 epidemic, consumption of processed potato products decreased, and consumption of fresh potatoes increased. China is the world’s largest potato producer with more than 4.81 million hectares of area under potato production and 90.32 million metric tonnes of potatoes produced in 2018. This accounts for 27.36% of the world’s planting area and 24.53% of the world’s potato production. The proportion of potatoes processed in China was about 12% in 2017, mostly dominated by starch production. However, the recent policy of the Chinese government to popularise potato as a staple food has created new markets for processed potato products other than starch.
