The present study aimed to investigate whether the exogenous addition of amylase enhances the nutritional value of pea seeds for broiler chickens. In total, 84 1-day-old male broiler chickens (Ross 308) were used for the experimental study. During the first phase of the experiment (1-16 d), all birds in each treatment were fed with a corn-soybean meal reference diet. After this time, the first treatment (control) was still fed the reference diet. In the second and third treatment, 50% of the reference diet was replaced with 50% pea seeds. In addition, the third treatment was supplemented with exogenous amylase. Animal excreta were collected on 21 d and 22 d of the experiment. The birds were sacrificed at the end of the experiment (23 d), and samples of ileum content were collected. The experimental results showed that the exogenous addition of amylase significantly improved ( < 0.05) the apparent ileal digestibility (AID) of the crude protein (CP), starch, and dry matter (DM) of pea. In addition, an improvement in the AID of essential amino acids in pea seeds (except Phe) was observed. The trend in the AME values was also noted ( = 0.076). It can be concluded that supplementation with exogenous amylase improves the nutritional value of pea seeds in broiler chicken nutrition.

Edible legume sprouts have been proposed as a promising plant-based source of the enzyme diamine oxidase (DAO), which plays a key role in degrading histamine at an intestinal level and preventing the development of histamine intolerance symptoms. However, the temperature and humidity conditions required for seed germination can also favor the rapid growth of yeast and mold, potentially compromising sprout yield and quality. The aim of this study was to evaluate the influence of different seed disinfection treatments on both the germination rate and DAO enzymatic activity in sprouts of four species.

Article Synopsis
- Tarhana is a traditional fermented food known for its nutritional benefits and shelf life, and this study explored how adding pea protein isolate (PPI) affects its properties.
- As the amount of PPI increased in tarhana, the protein content rose significantly, reaching over 76% in the highest PPI formulation, and also increased the antioxidant capacity and key polyphenols.
- The study found that PPI not only improved the digestibility of the protein and lowered the glycemic index of tarhana, making it healthier, but also showed potential for enhancing the nutritional profile of this traditional food.

Null mutations for genes encoding a major seed storage protein in pea, vicilin, were sought through screening a fast-neutron mutant population. Deletion mutations at four or five vicilin loci, where all vicilin genes within each locus were deleted, were combined to address the question of how removal or reduction of a major storage protein and potential allergen might impact the final concentration of protein per unit mature seed weight, seed yield and viability. While the concentration of seed protein was not reduced in mature seeds of mutant lines, indicative of a re-balancing of the proteome, notable differences were apparent in the metabolite, proteomic and amino acid profiles of the seeds, as well as in some functional properties.

Expanded insect production represents a source of post-breeding residues (frass) that can potentially be used as a soil additive. These types of biofertilizers are carriers of recirculated nutrients, as well as organic matter. In the present study, we investigated whether the bean waste (BW) and pea waste (PW) in the form of crushed seeds and post-production leftovers, naturally rich in proteins, were suitable as a substrate for rearing black soldier fly (Hermetia illucens) larvae.
