Millets are the staple grains in Asia and African countries, and they are the super future food because of their nutritive and disease-preventive nature. Pearl millet is one of the most nutritious cereal grains, and its protein lacks gluten, which makes it a suitable base material for the preparation of gluten-free products. However, gluten is necessary because of its unique viscoelastic nature, which makes the most innovative bakery items. In this study, 50% refined wheat flour (RWF) has been replaced with pearl millet flour (PMF) to prepare a muffin, and a ghee residue is utilized to make a ghee residue powder (GRP) as a functional ingredient to replace whey protein concentrate (WPC) in the eggless muffin. Substitution of fat with GRP reduced the specific gravity of batter from 1.05 to 0.99; lightness value was considerably decreased, whereas the redness and yellowness values increased from 1.06 to 8.32 and 23.62 to 26.20, respectively. Replacement of RWF with PMF affected the lightness and specific gravity of the batter. Substitution with PMF and GRP reduced the viscosity from 13.83 Pa·s to7.08 Pa·s. Gelatinization temperature of batters varied with substitution of flour and fat with PMF and GRP. Muffin volume dramatically decreased from 56.19 to 36.84 cm³ with substitution of GRP and PMF. Weight loss was increased from 12.14 to 13.68% by substitution. The hardness and springiness were reduced with substitution.

Significant variations (<i>p</i> &lt; 0.05) were detected in fatty acid composition among different foods. A comparatively higher fat content (&gt;17.5 g/100 g) was observed in 95% of pastry samples, while 51.5% of total foods exceeded the national threshold limit (8 g/100 g) for children.

Therefore, the EF becomes an alternative for coating HC because it can maintain product mass, shelf life, and flavor. This study is aimed at determining edible film (EF) characteristics and analyzing EF’s prospects in coating HC. The research method was conducted in two stages. The first stage was to make a whey base EF solution with 1%, 1.5%, and 2% KF. The EF was analyzed using a randomized complete block design. The analysis result of whey-based EF combined with KF was then conducted in the second stage of the research by applying HC produced in the laboratory and then stored for 0, 10, 20, and 30 days, respectively.

This study was performed to investigate the effect of delayed precooling on the quality and incidence of anthracnose during storage of Irwin mango at different operational times after the harvest. Therefore, in this study, Irwin was precooled for 30 min at 3, 6, 12, and 24 h postharvest and immediately stored in a cold room at 5°C. The appearance, anthracnose incidence, respiration rate, ethylene production, firmness, total soluble solids (TSS), titratable acidity (TA), and fruit overripening rate were monitored throughout the shelf life. Early precooling was found to delay anthracnose incidence during the shelf life. Furthermore, the fruit respiration rate during the shelf life was negatively correlated with the precooling delay. The respiration rate of fruits precooled for 3 h after harvest was 8.08 mg CO₂ kg^–1 h^–1 and retained a good appearance throughout the shelf life.

However, the current automated production line for green tea heavily relies on manual methods to determine M_C, which leads to low productivity and inadequate automation. Therefore, there is an urgent need for a fast, accurate, and convenient M_C detection method. In this study, near-infrared spectroscopy (NIRS) data were collected from seven stages of green tea processing and preprocessed using various techniques, such as Savitzky-Golay (SG) and detrend (DT), to reduce spectral noise. Subsequently, feature variables of the preprocessed spectral data were selected using full-band principal component analysis (PCA) and competitive adaptive reweighted sampling (CARS). Afterwards, prediction models for M_C of green tea were developed using partial least squares regression (PLSR) and back-propagation neural network (BPNN). To address the convergence speed and local optima issues of BPNN, the study proposes an adaptive probabilistic genetic algorithm (AGA) to optimize the initial weights and thresholds of BPNN, including single and double-hidden layers, respectively. The results demonstrate that the double-hidden SG-DT-PCA-AGA-BPNN model outperforms the single-hidden layer model, achieving a high correlation coefficient (<i>R</i>_<i>P</i>) of 0.994 and a low root mean square error (RMSEP) of 1.01%.
