Non-destructive assessment of quality parameters of white button mushrooms using image processing techniques.

Considering that appearance of white button mushroom (WBM) as the trigger for registering its quality, this study was aimed at analyzing the visual cues by the application of image processing tools. While colour space and skewness was used for estimating chromatic and morphological characteristics; onset of discolouration of WBM was predicted by hyperspectral image analysis. Undamaged (UD) and damaged (D) mushrooms were stored under refrigerated conditions (3-5 °C and 90% R).

Non-destructive classification and prediction of aflatoxin-B1 concentration in maize kernels using Vis-NIR (400-1000 nm) hyperspectral imaging.

Aflatoxin-B1 contamination in maize is a major food safety issue across the world. Conventional detection technique of toxins requires highly skilled technicians and is time-consuming. Application of appropriate chemometrics along with hyperspectral imaging (HSI) can identify aflatoxin-B1 infected maize kernels.

Chemometric strategies for nondestructive and rapid assessment of nitrate content in harvested spinach using Vis-NIR spectroscopy.

The overuse of nitrogenous fertilizers leads to an increase in the nitrate content of green leafy vegetables. Consumption of food with excess nitrate is not advisable because it results in human ailment. In this study, spinach leaves were harvested from plants grown under nine varying (0 to 400 kg/ha) nitrogenous fertilizer doses.

Rheological, nutritional, functional and sensory properties of millets and sprouted legume based beverages.

The present study investigated the effect of processing on the nutritional, functional, organoleptic and rheological properties of millet and sprouted legumes beverage flavored with jaggery (B1) and buttermilk (B2) for its processing suitability. The millets, sprouted legumes, flavoured with jaggery (B1); and buttermilk and salt (B2), used influenced the suspension stability, nutritional, sensory quality and rheology of beverages. Millets imparted minerals and starch while sprouted legumes improved solubility and extractability of nutrients and also increased the levels of anti-oxidants and flavonoids.

Effect of composition and storage time on some physico-chemical and rheological properties of probiotic soy-cheese spread.

Probiotic soy-cheese spread was prepared by fermenting soymilk with specific probiotic starter culture, and there after processing the coagulated mass. Soy cheese spread samples had more than 10 cfu/g of viable probiotic count at the time of preparation; and had around 17.6% protein, 25.

Quality characteristics of sauerkraut fermented by using a Lactobacillus paracasei starter culture grown in tofu whey.

The quality parameters of sauerkraut fermented using Lactobacillus paracasei in terms of its lactic acid bacteria count, texture, colour and biochemical properties were studied. As a starter culture L. paracasei grown in tofu whey was used for sauerkraut fermentation.

Quality characteristics of gluten free bread from barnyard millet-soy flour blends.

The effects of formulation of leavened bread by using varying levels (for 50 g base flour) of soy flour-barnyard millet blends (with 5.74, 6.25, 7, 7.

Evaluation of nutritional, textural and particle size characteristics of dough and biscuits made from composite flours containing sprouted and malted ingredients.

Composite flours (CF) using cereals, legumes, millets, soy-protein isolate, dairy ingredient and fruit without refined flour were used for preparing multi-nutrient biscuits. Dough and biscuits were evaluated for physical, nutritional and textural properties, particle size, colour and sensory evaluation and compared against refined-flour biscuits (C). Effect of malting and sprouting on biscuit quality were also analyzed.

X-ray imaging methods for internal quality evaluation of agricultural produce.

A number of non-destructive methods for internal quality evaluation have been studied by different researchers over the past eight decades. X-ray and computed tomography imaging techniques are few of them which are gaining popularity now days in various fields of agriculture and food quality evaluation. These techniques, so far predominantly used in medical applications, have also been explored for internal quality inspection of various agricultural products non-destructively, when quality features are not visible on the surface of the products.
