Mung bean is a rich protein source, but its native form has limited solubility and functionality for food applications. As a promising agro-based crop, mung bean offers a sustainable alternative to traditional protein sources, especially in regions with limited access to resources. This study optimized mung bean protein hydrolysate (MBPH) production using response surface methodology (RSM), investigating the effects of alcalase concentration (2-7%) and hydrolysis time (2-7 h) on its physicochemical and functional properties.

Lingzhi mushroom () is known as a medicinal mushroom that can be utilized in various functional foods available in the market, including powders, dietary supplements, and tea. However, its use is limited due to factors such as bitterness, flavour, and astringency. The objective of this study is to characterize and quantify the sensory profile of Lingzhi mushroom samples (fresh, dried and Lingzhi extracts) using quantitative descriptive analysis and investigate the physicochemical and sensory properties of encapsulated Lingzhi extracts using different ratios of wall material (maltodextrin, gum Arabic and modified starch from rice flour).

Article Synopsis
  • Gelatin, honey, xylitol, and propolis extract were investigated for their roles in creating honey gummy jelly (HGJ) with enhanced properties.
  • The optimal HGJ formulation included honey (32%), xylitol (14%), and gelatin (7%), which achieved a balance of hardness, gumminess, and overall acceptance in taste tests.
  • Adding 2% propolis extract not only improved the gummy jelly's phytochemical properties but also effectively inhibited the growth of various bacteria, highlighting its potential as a healthy gummy product.

This research aims to study the physicochemical and sensory evaluation of high energy cereal bars (HCB) and their consumer acceptability using logistic regression. The HCB was prepared and formulated under using a mixture design (d-optimal) experiment with three centerpoints, namely, cereals (60-66%) fruits (14-20%), and sweeteners (20-26%). The regression analysis indicated that the three main ingredients affected physicochemical properties (color value, hardness, and stickiness), chemical properties (a, total carbohydrate, gross energy, reducing sugar, non-reducing sugar, and total carotenoid), and sensory properties.
