Rice brokens were utilized in the development of pasta products. Response surface methodology (RSM) was used to analyze the effect of pre-gelatinized rice flour (from rice brokens), vital gluten, water, glycerol monostearate (GMS) and sodium alginate on the quality responses (sensory, cooking quality, rehydration ratio and solids loss) of the pasta product. A rotatable central-composite design was used to develop models for the responses. Responses were affected most by changes in rice flour and vital gluten levels and to a lesser extent by water, GMS and sodium alginate levels. The maximum sensory score (39.69), cooking quality (12.38), rehydration ratio (3.11) and minimum solids loss (15.64) were identified at 671.05 g kg-1rice flour, 242.40 g kg-1water, 74.70 g kg-1vital gluten, 2.14 g kg-1GMS and 9.71 g kg-1sodium alginate levels.

Abstract

In the modern era, nutraceutical properties of horticultural crops are indispensable to determine their adaptability to different agro-ecological regions. The present study exploits the potential of mulches (P: plastic mulch; S: straw mulch; N: No mulch) in relation to drip irrigation (I1: 100%, I2: 80%, I3: 60% of crop evapotranspiration (Etc)), and fertigation (F1: 100%, F2: 80%, F3: 60% of recommended dose of fertilizer (RDF): 125 kg N, 62.5 Kg P2O5, 62.5 kg K2O per ha) on Pak choi at three maturity stages in the North West region of India. Plant fresh weight was the highest at 55 days after transplanting (DAT); however, maximum soil plant analysis development (SPAD) values were registered at 45 DAT. Antioxidant activity, FRAP, DPPH, phenols, flavanols, total sugars, ascorbic acid, free amino acids, and irrigation water use efficiency were observed significantly higher in plants grown on plastic mulch at different levels of irrigation and fertigation. It is envisioned that Pak choi plants had the highest nutritional value at 45 DAT from plots mulched with silver-black, irrigated at 80% Etc, and fertigated at 100% RDF. The nutrient enriched plants are used for green salad and as ingredients for the preparation of many recipes in the semi-arid and sub-tropic areas of India.
