Apple (Malus domestica) belongs to the family Rosaceae. It is one of the most commonly cultivated fruit in all temperate zones of the world and holds an equally important place in the global economy. Apple is a climacteric fruit and undergoes metabolic changes even after the harvest and thus prone to post-harvest losses. The packaging of apples plays an important role in extending the shelf life of the apples and also maintains the quality during distribution and transport. The prime role of packaging is to contain the food commodity and protect the enclosed product from external damage. But other functions such as traceability, convenience and temper evidence are of secondary importance. Different packaging techniques are employed for the packaging of apples which include both conventional (wooden boxes, corrugated fiber boxes, crates) and non-conventional packaging like modified atmosphere packaging (MAP), active packaging, edible coatings, etc.

Researching on potential biopolymer sources with the aim of developing edible films with better mechanical and barrier properties has become innovative as it would be a key factor to minimize the use of synthetic polymers in food packaging. Therefore, different biopolymers such as galactomannan have been gaining attention recently. Fenugreek seed gum is a rich source of galactomannan which is minimally researched on its applicability in edible film making. The degree of galactose substitution and polymerization are the main factors that determine the functional properties of galactomannan. A strong and cohesive film matrix cannot be produced from fenugreek seed gum as its molecular interaction is weakened due to the high galactose substitution with a high galactose/mannose ratio, 1:1. Structural modifications of galactomannan in fenugreek seed gum will lead to films with the required mechanical properties. Hence, this review summarizes recent scientific studies on the limitations of fenugreek seed gum as a film forming agent and the specific modification techniques that can be applied in order to increase its film forming capability and performance.

Rice products, including those given to infants, could be naturally polluted with arsenic. This issue for all age groups should be a top priority for the world food industry and the public. Food regulators assume incorrectly that infants’ food and other rice products are safe, and health, agriculture and commerce authorities follow no clear guidelines. A common measure has been to place a ML on the amount of iAs in white rice and food intended for children and pregnant women. Although oAs is less toxic than iAs, it is still toxic; consequently, the ML of arsenic for the different age groups should be also specified. However, the ML of iAs in polished white rice for infants is very low (100 μg/kg for infants and 200 μg/kg for adults) and is difficult to measure. Using neutron activation for research is very useful in improving safety standards in the food industry. The second purpose of this review study is to report on the experimental results and methods used for measurements adopted at the Delft Reactor in the Netherlands with a colleague of the quantity of arsenic in 21 samples of different rice products from a variety of brands.

Active packaging systems come under novel techniques and are creating demands in food packaging aspects. They are specially designed for food products where shelf life is a key driving factor. Their wide range of functionality preserves the color, texture, smell, and taste of the food item retaining their freshness and edibility for longer than any other methods available on market. An active ingredient in packaging systems enables efficient consumable quality which resulted in reduced complaints from consumers. However, techniques must be inexpensive and environment-friendly. The use of biodegradable packaging systems reinforced by exploiting natural compounds forms the latest trend to attract consumer demand in substituting synthetic preservatives in foods that can protect against food spoilage. Natural extracts have gained commercial importance in active packaging nowadays for the delivery of safe and high-quality foods that are being employed in both fresh and processed produce. Development and use of innovative active packaging systems in varied forms are expected to increase in the future for food safety, quality, and stability. The review overviews the beneficial effects of plant acquired components in modulating product quality in packaged form for commercial aspects in the market.

The poultry industry is trying to reduce feed costs by replacing soybeans and corn with new protein sources like insect-derived (ID) and marine-based (MB) ingredients. This strategy requires evaluating not only chicken performance and carcass characteristics, but also the sensory properties of the produced meat and eggs. The MB and ID products are potentially valuable sources of proteins, amino acids, fatty acids, vitamins and minerals in animal nutrition. This systematic review reports the effects of using these ingredients including fishmeal and oil, fish protein hydrolysates, fish silage, and seaweeds and insect products like insects’ protein and oil on the sensory properties of poultry meat and eggs. Studies show that excessive use of these compounds in poultry diet has a significant effect on the sensory properties of meat and eggs. However, there are conflicting reports regarding the use of ID and MD ingredients and their effects on the sensory properties of poultry meat and eggs. Therefore, it is necessary to have a systematic literature review on the subject and draw a clear conclusion. The study emphasizes the importance of using sensory assessment in the poultry nutrition studies’ when using new ingredients and providing practical information for poultry nutritionists and processing professionals.

Heavy metal discharge from various metallurgical industries has been of particular concern in India over the last few decades. Similarly, management and disposal of wastes that are generated out of agricultural commodities processing is a huge task for processors. The researchers have been focusing on a new process for remediation of heavy metals, among which biosorption is an emerging technology. Adsorption using agricultural and food industry wastes (AFW) has shown a greater absorption rate than the conventional system due to the presence of the functional groups. In addition, these reported AFW exhibited better adsorption efficiency when modified with acid, alkaline, and other chemical solvents. In this context, utilization of agricultural and food waste as bio-sorbent could simultaneously benefit both water treatment and waste management. This review seeking to address the possibilities of using biosorption as green technological approach for removal of heavy metals and also focuses on various parameters that are required to use AFW as an efficient system for biosorption. However, commercialization and implementation of this process in industrial scale is necessary for successfully utilizing AFW as low-cost adsorbents.

Coffee is a complex mixture of chemicals, which provide biologically active compounds with various health benefits. The some biologically active compounds arising from both its natural structure and formed after processing were determined as an antioxidant capacity of coffee beverages. In this study, we aimed to determine how roasting levels of Arabica coffee seed (light, medium, dark) and three brewing techniques—decoction methods (Turkish coffee), infusion method (filter coffee) and pressure methods (Espresso)—affect total antioxidant capacity in a cup of coffee beverage by electrochemical methods such as square wave stripping voltammetry (SWSV), differential pulse stripping voltammetry (DPSV) and cyclic voltammetry (CV). Antioxidant capacities of the coffee samples in terms of the equivalent amounts were determined according to standard oxidation peaks of rutin and caffeic acid. The highest antioxidant capacity was found in espresso coffee prepared at light roasting coffee seeds as equivalent the routine and caffeic at 9.4 ± 0.2 g/L and 19.7 ± 0.7 g/L, respectively with SWSV on a carbon paste electrode. As a result, SWSV, DPSV and CV voltammetric methods, fast, reliable, fully validated and without any pretreatment are alternative to conventional analytical methods to evaluation antioxidant values in any food samples.

This work aimed to develop an active and intelligent film based on soluble soybean polysaccharide (SSPS)/Malva sylvestris extract (MSE) to extend the shelf life of foodstuff and detect indirectly the food spoilage. The influence of MSE content on physico-mechanical properties, biological activity, and pH sensitivity of the SSPS-based films was examined. When the MSE concentration increased from 0 to 6% (w/w), water solubility and water vapor permeability of the films decreased (p ˂ 0.05). Clear antioxidant and antibacterial capacities were observed for SSPS films incorporated with different concentrations of MSE. SSPS/MSE films could sense the pH variation in a pH range of 7 to 8. SSPS/MSE film was used to detect the spoilage of shrimp and showed a pH-sensitive highly distinctive color variation from grey to dark green as the shrimp’s quality altered. Overall, SSPS/MSE film can be introduced as a promising candidate for application as active and intelligent packaging.

This work presents the study of the moisture ratio and carotenoid compounds in dried mamey (Pouteria sapota) using non-invasive spectroscopic techniques. The drying behavior of mamey at 64 °C by a homemade solar dryer is analyzed by fitting the experimental data to four different mathematical drying models. In addition, this result is compared with other drying techniques, namely by heat chamber with natural convection at temperatures of 50 °C and 60 °C. The results show that the Lewis model is the one that best fits the experimental moisture ratio curve of mamey. On the other hand, Near-Infrared and Terahertz spectroscopic techniques are used to estimate the moisture ratio, since water absorption is most sensitive at these frequencies. Fourier Transform Infrared-attenuated total reflectance and Raman spectroscopy are performed to detect the carotenoid compounds in dried mamey. This compound has important applications in the food industry and health benefits. To our knowledge, there are few studies on the dehydration of Pouteria sapota as well as its characterization using spectroscopic techniques for the detection of moisture ratio and carotenoid content; therefore, this study can be useful in agriculture and food sectors when detailed information about the cited parameters is needed.

Alginate (ALG) and various gums are potential biomaterials to be employed in hydrogel designs for both food and biomedical applications. This study evaluated a multicomplex design by combining food grade polymers to examine their polymer–polymer interactions and design an oral delivery system for pomegranate concentrate (PC). ALG was replaced with gum tragacanth (GT), xanthan (XN) and their equal combinations (GT:XN) at 50% ratio in hydrogel fabrication. In addition to CaCI2 in binding solution, honey (H) and chitosan (CH) were also used during physical crosslinking. Relaxation time constants in NMR indicated poor ability of GT for water entrapment especially in the presence of honey (S2H). They also confirmed FTIR results indicating similar trends. Strong negative correlations were observed between T2 and texture results. GT replacement of ALG especially in the use of single CaCI2 (S2) promoted higher PC release up to 80% in digestive media compared to XN substitution (S3). This study promoted use of LF NMR as an indicator for polymer mixture characterization in complex gels. ALG based gels could be modified by replacing ALG with different kinds of gums and with use of different binding solutions to regulate target compound release in food and pharmaceutical fields.
