“…While being absent in BP, α-tocopherol was found for BM (0.07 AE 0.00 mg/100 g), BS (0.13 AE 0.00 mg/100 g), whereas presence of β-tocopherol was detected in BM (0.48 AE 0.01 mg/100 g), BS (0.47 AE 0.00 mg/100 g) and BH (0.50 AE 0.01 mg/100 g). Some earlier studies also reported the enhancement of α-tocopherol along with temperature till 60 C in convective drying (Laoretani et al, 2014;Al Juhaimi et al, 2018). This may be due to the stability of γ-tocopherol methyltransferase enzyme which converts γand δ-tocopherols into αand β-tocopherols at ambient and/or higher temperature (<50 C) (Shigeoka et al, 1992).…”

Aegle marmelos (L.) is a seasonal fruit that contains significant amounts of bioactives like, phenolic acids (gallic acids, 2,3-dihydroxy benzoic acid, chlorogenic acid, p-coumaric acid, vanillic acid), flavonoid (rutin), organic acids (oxalic acid, tartaric acid, malic acid, lactic acid, acetic acid, citric acid, propionic acid, succinic acid, fumaric acid), vitamin C, vitamin B group (thiamine, niacin, pyridoxine, pantothenic acid, biotin, cobalamins, riboflavin), tocopherols (α-tocopherol, β-tocopherol, γ-tocopherol, δ-tocopherol), carotenes (α-carotene, β-carotene, γ-carotene, δ-carotene) and also rich in essential minerals (potassium, calcium, phosphorus, sodium, iron, copper, manganese). This study provides a comprehensive composition analysis (determined using RP-HPLC and Energy Dispersive X-Ray Fluorescence (EDXRF) Spectroscopy). In vitro medicinal activities (antioxidant activity, anti-inflammatory activity, anti-diabetic activity) are quantified for different bael samples. The study also investigates the changes of these bioactive components with freeze, sun, hot air, and microwave drying. The study gives a proper vision to preserve the nutraceutically rich pulp by converting it into fruit leather.

“…Attempts to improve the barrier properties of these biopolymers include the addition of oil, such as vegetable oils, in film formulations. Canola oil is characterized by being very low in saturated fat and high in monounsaturated fat and contains significant amounts of omega-3 (alpha-linoleic acid) and omega-6 acids (linoleic acid), both of which are essential for the human diet (Laoretani et al, 2014) [14]. κ-carrageenan and gelatin have been known to increase the viscoelasticity of gels (Derkach et al, 2015) [15] and to exhibit good filmforming properties (Pranoto et al, 2006) [16].…”

κ-carrageenan/gelatin mixtures and canola oil can form an emulsion film when they are well combined and can mediate the release of volatile substances. The objectives of this study were: 1) to investigate the effect of different ratios of κ-carrageenan/gelatin with and without the addition of canola oil on moisture content, solubility, thickness, water vapor transmission rate, tensile strength and percent elongation, 2) to study the release of ethyl acetate with different ratios of κ-carrageenan/gelatin with added canola oil. Edible films were prepared with varying ratios of κ-carrageenan/gelatin with and without the addition of canola oil. Ethyl acetate release from selected films was also observed. The results showed that different ratios of κ-carrageenan/gelatin with canola oil addition induced changes in moisture content, thickness, water vapor transmission rate, and tensile strength (p<0.05). A significant decrease in the water vapor transmission rate of films was induced by canola oil with a ratio of κ-carrageenan/gelatin of 1.35:1.65. In addition, κ-carrageenan/gelatin at a ratio of 1.35:1.65 with added canola oil triggered a larger release of ethyl acetate. These findings confirmed that different ratios of κ-carrageenan/gelatin with canola oil could be used to tailor emulsified films with enhanced barrier properties and to trigger the release of volatile substances.

“…The grains were cleaned in dockage tester (Make: Carter‐Day company, N.E, Minneaplis, MN) and specific gravity separator (Make: Carter‐Day company, Oliver manufacturing Co. INC) for removing all foreign matters and immature small sized grains. The cleaned grains were dried in the hot air oven up to 8% (wb) moisture content (at 70°C for 24 hr; Laoretani, Fernández, Crapiste, & Nolasco, 2014) for complete dehulling of grains. Dehulling and splitting of all grains were carried out in soybean dehuller (Make: GBPUAT, Pantnagar).…”

A polar green solvent based Microwave assisted oil extraction from low oil content source like bhat seed is one of the novel and sustainable approach. The understanding of exact mechanism of mass transfer and hence oil extraction is vital for its industrial scale application. The kinetics of oil extraction and their modeling is carried out in present investigation. The MAE of oil from different size particles (<1, 2, and 4 mm) of bhat seed sample was carried out through isopropanol as solvent. Fick's law based model and two stage (washing and diffusion) extraction based empirical model was fitted to the experimental data. Fick's law shown the best fit to all three particle sizes with R 2 .98, .98, and .97, respectively. The diffusion rate was observed to be decreased from 0.54 to 0.26 min −1 with increase in particle size. Empirical model shown that the washing stage was most predominant over diffusion with extraction rate few hundred times the diffusion. Practical Application In recent years, microwave assisted extraction (MAE) attracts the industrial interest because of various advantages. But, the phenomenon of MAE is considerably different than conventional solvent extraction. The understanding of insight in to the process of mass transfer kinetics taking place during extraction is the key requirement for design and scale-up of the extraction system. Therefore, the present investigation understands the mass transfer and extraction dynamics taking place at molecular level especially in low oil content source, which will help for large-scale commercial design of MAE systems. 1 | INTRODUCTION Bhat is one of the underutilized crop belongs to the family of black colored soybean. This has been used as traditional nutritionally rich foods and in folk medicines from hundreds of years in various part of Asia. The bhat has been used traditionally as medicine, for detoxification, anti-inflammatory processes, antimutagenicity, to improve the blood, inhibition of low-density lipoprotein oxidation, and DNA dam
