<p>Given its very important economic and environmental interests, the cultivation of carob tree in Algeria has experienced remarkable development, which is reflected in the methods of plant multiplication, the increase in the surface area of its cultivation, and in particular, the growing number of carob fruit processing industries (first and second transformation). In this context, the present study focused on the evaluation of the food quality of whole pod powders and carob pulps from three different regions of Algeria (Boumerdes, Relizane, and Tissemsilt). The experimental part presents a morphobiometric characterisation of carob pods carried out during the 2020–2021 production campaign — length, width, mass, volume, thickness, size index (length/width), the number and mass of seeds, analysis of the food quality of carob powders from whole pods and their pulps and determining their physicochemical properties (particle size, pH and dry matter), nutritional properties (ash, crude proteins, total sugars, crude fibres, fats) and sensory (colour, taste, texture, and smell). The results showed that the morphobiometric characteristics of the carob pods studied (physicochemical, nutritional, and sensory properties of the powders) strongly depend on the biogeographical site of the carob tree and the conditions of its production. Compared to the other carob fruit powders analysed, Relizane carob pulps powder showed a better sensory appreciation; this powder was characterised by a colour (100% light brown), taste (50% sweet, 50% very sweet), texture (100% fine), and odour (100% carob with strong intensity). Indeed, the study of the food quality of the two types of powders obtained separately from whole pods (seeds and pulps) and from the pulps is very valuable and opens possible ways of food valorisation of carob tree fruit.</p>
