Abstract

The eastern sub-Himalayan plain of India is a popular potato growing belt in which vast scope exists to introduce processing grade cultivars. The selection and introduction of a better quality processing grade cultivar in this region may pave the way for the processing industries. Keeping these in the backdrop, this study was conducted at Instructional Farm of Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India under eastern sub-Himalayan plains during winter seasons of 2016–17 and 2017–18 in which seven processing type potato cultivars (Kufri Chipsona-1, Kufri Chipsona-3, Kufri Chipsona-4, Kufri Frysona, Kufri Himsona, Kufri Surya and Kufri Chandramukhi) were evaluated in terms of different quality parameters pre-requisite for chips processing viz., dry matter content, specific gravity, starch content, chips colour score, crispiness and hardness of chips through randomised complete block design (RCBD). The study revealed wide variation in all quality parameters amongst the cultivars. Cultivar ‘Kufri Frysona’ showed the highest specific gravity (1.121) as well as dry matter content (23.35%) followed by ‘Kufri Chipsona-3’. The cultivar ‘Kufri Frysona’ showed the highest starch content (28.52%) too. Chips prepared from ‘Kufri Chipsona-1’ were recorded to be crispier with a relatively lower value of deformation before the first break and less hardness value. All processing type potato cultivar reflected the chips colour score <3 (evaluated, based on 1–10 scale, 10 being the darkest and least desirable) though ‘Kufri Frysona’ had the lowest chips colour score (1.50) signifying its superiority for the region. ‘Kufri Frysona’ cultivation could be recommended in this agro-climatic region particularly for chips manufacturing potato industries.

Highlights

This article is an open access articlePotato (Solanum tuberosum L.) is a world food crop having a significant contribution towards food and nutritional security, especially in the developing world
India is the third-largest producer in the world, mostly table purpose potato is grown in the country with a little share of processing type potatoes
It was observed that the processing type potato cultivars did not vary significantly in terms of specific gravity which ranged between 1.110 to 1.121 (Table 1)

Summary

Introduction

Potato (Solanum tuberosum L.) is a world food crop having a significant contribution towards food and nutritional security, especially in the developing world It is considered as a balanced food due to the presence of high-quality proteins, vitamins and minerals, trace elements with lesser energy [1]. These table purpose cultivars were not preferred by the industries though sometimes they used the table purpose potato for making crisps and french fries due to lack of availability of suitable cultivars. It has been estimated that the demand for processing type potato with desirable traits would rise up to 25 million tonnes by 2050 [3]
